99.5% is compressed well above 200 bar/~3000 psi and delivered in STEEL WELDING TANKS for everyday use from every major gas welding supplier known. Look forward to any help or advice.Thank you. i guess i can do same with bigger maybe cylindrical balloon (human size could be) and cook something. Hydrogen; maintenance of liquid state and the devices in order to do this requires an industrial MAZMAT type licensing and certification. Rinse wash and repeat till it equals out. Don't think you can get around this problem by using a thicker walled metal tank such as one designed for CNG or Acetylene. Why or why not? The main function of the compressor is to compress the gas … Really gets the imagination going.... http://www.treehugger.com/sustainable-product-design/is-a-hydrogen-powered-house-really-green.html. The composition of wood gas and the necessary fuel-to-air combustion ratio make storing wood gas uneconomical. Reply 0. http://hydrogenhouseproject.org/hydrogen-myths.html. Do you just make this up or are you paraphrasing (badly) some other source? Such firms as Quantum (partly own by GM) and Dynatek now sell filament-wound carbon-fiber tank lined with an aluminized polyester bladder instead of the TRADITIONAL SOLID METAL LINER.". This I have personally seen done. ok, this is getting more interesting... Materials to store hydrogen: www.sigmaaldrich.com/materials-science/material-science-products.html?TablePage=16375039. Peace and common fear mongerers..... work together to find a solution don't be a wet towel. Answer 2) The amount of space necessary to compress hydrogen far exceeds the capacity of a propane cylinder. Other applications are wood gasifiers & they can be junctioned in to run engine in emergencies ,can use all sorts of fuel sources. Gearhead318@hotmail.com is my email to order my hydrogen generator plans. Yet natural gas doesn't compress as easily. That is why the use of a metal hydride is mentioned so you can store vast amounts in a small space then chemically release the hydrogen when needed, by releasing into a secondary holding container to be used on demand. What happens if you take a gas and squeeze it into a smaller volume at a constant temperature? 1) hydrogen and oxygen explode so you would need to evacuate ALL oxygen from the cylinder. It is then safe to handle. How is the power capacity (kW or MW) of a biogas installation determined? If this fails! Could you store it in a a propane tank for a grill, or maybe a refrigerant tank? The forums are retiring in 2021 and are now closed for new topics and comments. Looking forward to perfecting my PEM cells. Think of others in your science project. CNG combustion produces fewer undesirable gases than the aforementioned fuels. The higher energy cost of production is offset by much lower energy costs in distribution and handling. 4 years ago. Methane is considered to be a non-compressible gas. I was getting 300 grams from Prius batteries using a metal saw to cut into the battery, separating the plates, and scraping off the MH. I ran a hose out of the check valve to hot-glued bottle cap where you attatch a plastic bottle of your gas. Then it maybe one of the following: If a gas spring has been lying in stock for a while, the seal with which the nitrogen gas is kept inside can stick to the rod of the gas spring, when this … I modified a $10 air compressor from radio shack in a similar way to drcrash did it here: https://www.instructables.com/id/convert-a-tire-inflator-type-air-compressor-into-a/instead of using the hose fitting he used, you should use a small check valve you can find at any pet store in the aquarium section arranged so that you can blow air into the compression area, and not out. 6 … That means that whatever the mix proportion between air and hydrogen, a hydrogen leak will lead to an explosion, not a mere flame. but why I cant use the extracted metal hydride as it is? In the gas state, widely-spaced particles move around randomly. If you gave more information, for instance - what gas you want to compress - whether it is flammable - how much you want to store - what pressure you need to store it as - what kind of tank or bottle and valve you have to store it with - what it will be used for then you might get a more helpful answer. This makes the use of hydrogen particularly dangerous in closed areas (tunnels, parkings)..[47] Some differences with common fuels include the fact that pure hydrogen-oxygen flames burn in the ultraviolet color range and are nearly invisible to the naked eye, thus it requires a flame detector to detect if a hydrogen leak is burning. I was thinking of running an engine with pure hydrogen, not hho. If people are intersted there are some hints above to follow and learn more. I'm working on a hydrogen gas system in tanks and it's not the "scary everything dies" story. In this video I explain how you can compress hydrogen in propane tanks. Liquefied Gases. H2 can be heated providing it is not mixed with O2. It is wise not to say "can't" in our evolving science, my friends. ", Answer They here speak about how we can store large amounts of $\ce{CO2}$ in depleted oil fields, natural gas reserves or other such underground storage reserves. You just have to know the dangers and put in the steps to protect yourself. However storage of H2 in solid array is stable and safe. Please check out my other videos. Wood gas can be compressed and stored in a tank. 3. it is composed of elements. Employed internationally offshore on rigs, here's a standard rack of STEEL H2 gas bottles compressed at 200 bar: You cannot, I repeat cannot compress hydrogen into a propane tank, period, end of story. "Intelligent Application in Material World Select Papers from IPMM-2001". This will produce a good amount of hydrogen which can be used instantly. Answer The work done in this case and hence the power required to run this type of cooled compressors is the theoretically minimum possible limit. The exaggerated fear of hydrogen gas storage and "embrittlement" is epidemically rampant! """Gorrie’s process took advantage of the difference between temperature and heat. There is no reason you couldn't. The only _viable_ low carbon way of making hydrogen fuel requires a very high temperature nuclear reactor and if you're going to do it that way you might as well just expend extra energy and tack on extra carbon atoms extracted from the atmosphere. Read the "Storage" section of http://en.wikipedia.org/wiki/Hydrogen_economy#Production.2C_storage.2C_infrastructure for ideas. Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). Removing oxygen from a tank can be done, and using a compressor you can get more than a small amount. Helium is indeed smaller, because H2, but Hydrogen can permeate materials and diffuse in materials Helium cannot because Helium is mostly non reactive. 6 years ago, can i storage on a big hard balloon and connect to a little stove heater just for a evening cooking ? This explains why you can compress gases and why they flow. A gas will fill any container, but if the container is not sealed, the gas will escape. In other words you would have to heat the hydride to get the H2 out.The reason hydrogen tanks and hydride hydrogen service has been found to be save in cars if due to the fact that hydrogen is much safer than gasoline. This is not something I'd encourage an amateur to attempt. Collect enough of it and you can fill a small cylinder.Be careful of the white film that separates the two plates, this is potassium hydroxide and works like an acid. http://hydrogenhouseproject.org/the-first-consumer-hydrogen-house.html. but it doesn't matter any more because i find out that its impossible to do it at home (at least for me). Hydrogen is extremely dangerous. Hydrogen must be remove from all oxygen making hydrogen an inert gas form.2. A certain amount of pressure, around 46 bars, is recommended for the methane gas. A liquid will take the shape of its container, but is hard to compress. You do NOT need an engineering degree to handle liquified gases, including hydrogen. If hydrogen is introduced into combustion chamber without oxygen mixture then it is inert until contact with oxygen, therefore none explosive till that O2/Oxygen contact point of gas mixture. Refueling stations already in use afford H2 refueling within 3 minutes employing high-pressure hydrogen gas. Many thanks John. However, gasifiers used to collect and condense wood gas for immediate use may prove valuable as a future alternative fuel source. This is why you can pour, but not compress, a liquid. The inside plate is the positive side (contains NOOHI and not very good for hydrogen storage) and the outside plate is the negative side, that's the one you want. Can you send me the quotation of your generator on "indradeep1989@gmail.com". 2. it is composed of large particles. More on that in 12 hours. Ah I should have read down before I commented about fear mongering. The report is from Rocky Mountain Institute. Can we explain what happens in terms of the gas particles? Also, I remembered this project in Island where they have hydrogen stations performing electrolysis, and running different car brands running on hydrogen. yes but buying oxenated air would be much more expensive sinse all i haveto do for hydrogen in put in some water and plug it in. Answer Ahh the danger of speaking in absolutes. Purified hydrogen gas >99.5% is compressed well above 200 bar/~3000 psi and delivered in STEEL WELDING TANKS for everyday use from every major gas welding supplier known. The most common method the days is reduction of natural gas (the Haber process), at a net 60% energy loss over the raw stock. If you expose dry NIMH powder straight from a battery, as soon as it loses the moister it bursts into flames. Why: Apart from being hard to contain (a propane tank would lose substantial amounts of gas straight through the walls), Hydrogen is _extremely_ reactive and makes metals brittle - especially steels. Turn on the compressor and let it compress the gas. 3) Did I mention it will explode?Now, do some research into storing your hydrogen in a metal hydride state. sorry my bad english. In this state, with a temperature approaching absolute zero, it would be liquid methane. At some point, the air particles are start bumping into each other more and more and the ideal gas equation starts to break down. But show it a leak, even minute, and it will find its way out. Do not attempt liquid or compressed gas storage, it is just asking for trouble. [60][61] Its Maribor counterpart, Marprom has 19 CNG city buses in their fleet, … This minimum possible power to compress a gas from P 1 to P 2 is given by following equation, Here subscripts 1 and 2 correspond to inlet and outlet states of the gas, V is the inlet volumetric flow of gas. If you're using HHO forget that, it has it's own oxygen in the mixture. If you want, you can have a look at the article World can ‘safely’ store billions of tonnes of CO2 underground on carbonbrief.org (accessed 2019-10-13). Apart from the handling issues mentioned above, hydrogen fuel must be made from _something_. Metal hydride storage of hydrogen is very safe and stable. From the first fuel cell design in 1801 (that's 214 years ago), much of this has been considered, designed, and tested. I can do anything!! If its hho gas you want to compress, its also very simple and its very dangerous!!!! Hydrogen is more volatile than gasoline, hence it wil dissipate faster than gasoline. Yes, but don't expect that balloon to last more than a day. Atmospheric pressure is normally about 101.4 kPa (14.7 psi). Therefore, do not ruin this new H2 application to further your fuel economy, please be careful and be certain hydrogen will not have any areas to pocket in engine compartment awaiting an ignition point explosive. Putting aside the CO2 emissions, bear in mind that large chunks of the pollution issues with both gasoline and diesel revolve around the issue that the fuel isn't "pure" octane or the same long chain hydrocaron (diesel is at least 30 different hydrocarbons plus contamination). Will it not react with water and become obsolete? Thus, compression, which is essentially forcing the gas particles closer together, has a great deal of space to reduce. Hydrogen requires super high compression to store efficiently in gas form. If you gave more information, for instance- what gas you want to compress- whether it is flammable- how much you want to store- what pressure you need to store it as- what kind of tank or bottle and valve you have to store it with- what it will be used forthen you might get a more helpful answer. I will keep posted on it... What I do is run my electrolosis cell for the hydrogen-oxygen gas, and store it in plastic bottles. i want to compress hydrogen or methane. Solids are generally defined as "incompressible," but it is actually possible to compress some to a very small degree. dried pellets made from hay or manure or wood chip or lawn clippings, lantana, coal. Then close the valve and rebuild pressure in the hydrogen tank that's connected to your hydrogen generator. lol. But it is not at all as dangerous as the myth want you to believe. L. The forums are retiring in 2021 and are now closed for new topics and comments. https://hydrogenhouseproject.org/index.html. Fun fun. Helium will actually diffuse far quicker than Hydrogen. I don't know if it's exactly 90PSI so I only go for around 40PSI max for me. I have been looking at this for a little while now, and digging into metal hydrides. Then hook it to your hydrogen tank from your generator. There are many systems that use a hot H2 environment.Neodymium and Samarium can also be used to absorb and store H2. Safeopedia explains Compressed Gas Liquefied gasses are liquid at normal temperatures when they are inside cylinders under pressure. They won't sell to anyone that does not have a business license or has a business designed for chemical storage. Hopefully get a doctorate out of it. Hydrogen partially makes up for that fact by being more energy dense per unit mass — about 3 times as much as natural gas. (Think about a diving tank – 600 L of gas is compressed into a 3 L cylinder.) Best Answer If you really must use hydrogen then make it as you need it. Don't be such a "STOP DANGER" monger.

https://www.instructables.com/id/convert-a-tire-inflator-type-air-compressor-into-a/, https://www.instructables.com/id/How_to_use_Answers_Effectively/. "Myth #7 - we lack a safe and affortable way to store hydrogen in cars. You would have to lower the temperature of the tanks (substantially) before you could get it to compress. 2 years ago. High pressure hydrogen is even worse. 4 years ago. HHO does not seem sufficiently potent to run the engine. This is one of the reason oil refineries flare (burn off) excess methane. Hydrogen; if you do not storage H2 in liquid form, or gas form and have proper ventilation is still considered illegal for vehicular combustion volume metric efficiency usage in public highway motor applications, but currently is not enforced. Daniel Creaney in Manitoba Canada just add me . Don't try it. I also fill these tanks and blow them up to understand the dangers. Suppose I can provide a vacuumed propane cylinder, can you explain to me why I can not just keep pumping the hydrogen gas into the cylinder until it reaches the pressure I want? One gram of hydrogen takes up as much physical space as 11 liters of oxygen. 5 years ago. My conclusion, the banksters/ oil industry will do everything to misinform anything about hydrogen, "this could blow up"!!!! In the old days "town/coal gas" (about 80% h2, 5% CO and assorted other volatiles) was made by pyrolisis of coal in a reducing environment with water added. A manual way with man power would be good or low dc power.We run a large battery bank charged with a diesel generator, the hope is to convert a generator to methane and lpg back up. I read the rare earth magnets use metal hydride, and I was wodnering if they could be used to store hydrogen... www.intemag.com/media/HydrogenEmbrittlementandH2coating.pdf. Propane is probably cheaper, definitely safer, and you'd get more of it in a bottle. The compressor contains a series of chambers, each one equipped with a specially designed membrane. I have better things to do with my time. So i will try with methane! It is used as a fuel gas If you don't think this is possible, there are other means to generate hydrogen, from aluminium and lie (see movie below). Some are running engines with this technique (hydrolysis). The negative terminal of a NIMH battery in most cases contains LaNi5 which is a good metal hydride for storing hydrogen.The outside case of a NIMH battery (in all cases is the size of a AA battery) and made of stainless steel. The differences between a solid, liquid and gas are simple! Turn on the compressor and the bottle will collapse, and your gas will come out of the bike pump hose end.. https://www.instructables.com/id/How_to_use_Answers_Effectively/Without more information the only answer you are likely to get it jtobako's below. There are plenty of pyrolysis setups available to do the job (and there are twice as many hydrogen atoms available in a litre of diesel than a litre of liquid hydrogen). You may only be able to store half a liter or less of compressed hydrogen in that amount of space. By doing so, you decrease its volume because now the same number of molecules occupy a smaller space; you increase its density, because now, there are more particles per unit volume; you increase its pressure, because now the molecules strike the walls of the container more often; you … There are many different methods used to compress gasses. Answer So if you compress a gas, draw off part of its heat, … i think that is not enough because i read somewhere that you must extremely cool down the methane gas and then you can pressurize it. Bringing the particles closer makes room for more interaction because repulsive forces dominate. It still contains gas at atmospheric pressure. could you clarify what you mean by "return to gas form by means of nitrogen"? In general, it’s defined as how much a liquid or a solid can resist the pressure applied to compress it from all the directions. And because the particles are far away from each other, it can be compressed easily. Get it wet as soon as you take it out of the battery. Gases can be compressed because each gas particle has relatively vast amounts of room between it and all other gas particles the majority of the time. Not all MH will store hydrogen. However, there is a lot of interest in hydrogen in powering automobiles, so storing hydrogen has been studied. It's worth noting that one of the largest contributors to pollution reduction from both fuels is down to tighter refining specifications with lower allowed limits of contaminant such as sulfur and more stringent control over the mixures of hydrocarbons beind sold as "diesel" or "gasoline" (Ethanol mixed in reduces pollution levels slightly but the overall downsides are far worse than the positives). Some gases are so toxic that their release through a safety device would be hazardous. That way you have a much easier to handle fuel with a much higher energy density (see comment above about diesel). Gas is pumped into the first chamber, where the volume is constricted by the membrane. Norway has legislated out all gasoline, diesel & hybrid autos by the year 2025. Doing do will invalidate your public liability insurance and expose you to prosecution in most countries. When your hydrogen tank fills, open the tank a hair to let the gas in. it makes 280f air with good flow. When you compressed a gas, you are decreasing the distance between the particles. http://www.itm-power.com/project/island-hydrogen. Anyway..... Just dislike fear and egotistical "only my way is right" talk. Here is a good link on hydrogen, demystifying it. When you compress a gas it will turn into a liquid until the presser is taken off the compressed liquid and then it will turn back into a gas Is compressed natural gas a liquid?  It's not impossible. The gas needs to be compressed to approximately 200 psi (pounds per square inch) if about 4 gallons in quantity. This means hydrogen is being compressed in metal tanks... Also, if you look at this hydrogen house project (link above), you will find the guy has a massive amount of steel tanks to store his hydrogen reserves... https://hydrogenhouseproject.org/index.html this guy is a genius and he has stored hydrogen in a group of propane tanks , and his project is inspected , and code compliant. In order to compress water, you would need so much pressure. A solid is an object that has a set volume, and is hard to compress. Yes … a diesel engine generally operates by squirting a small quantity of fuel into a cylinder of air, and then compressing it 22 timesand it heats sufficiently to ignite the fuel 25 views View 2 Upvoters Sponsored by Raging Bull, LLC Liquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. Sorry. In other words, if you put raw hydrogen in a metal tank, you're making a pressure bomb (like the old trick of dry ice in a plastic bottle). I just thought up a way to compress the hydro-oxy gas mix I'm gonna get from my future electrolysis tank. ---Please Be Careful, and Be safe. You can describe the situation a little longer with the slightly modified real gas equation, up to a limit. Therefore to compress the gas spring for the first time, its probably better to mount it in the application, this way the cover or hatch then acts as a lever, making it easier to push by hand. Liquid hydrogen requires cryogenic storage technology such as special thermally insulated containers and requires special handling common to all cryogenic fuels. Hydrogen can be encouraged to be absorbed by a hydride by heating. As I mentioned to the guy above, ammonia bromide is very very promising. Gases. Keep me posted if you do that ! I cannot advise putting hydrogen into a propane tank, as it would be advising you to break the law.However i may be able to help you if you contact me via email, as I can steer you to a safe way to do this. You wouldn't - and you'd stop thinking about it. But it is not practically compressible for the least. If there are any carbon atoms in the metal matrix then hydrogen which penetrates the metal will bind to them to form methane and that adds internal pressure to the metal itself, further weakening it. Solid State storage of hydrogen is very safe. You can check out my videos and everthing I am going at my facebook. 11 years ago. It can auto ignite however under some conditions of o2 is in the tank or pipes to the tank, which is why you want to filter for purity. Not all compressed gas cylinders have safety devices. Make a small snip in the metal and peal it like an apple in a circular fashion. Question. I looked at their system and they do not appear to use hydrides, they are using a HIGH PRESSURE composite tank!! This brings up the oft-touted issue of hydrogen fuelled cars. There are three ways to store hydrogen, 1) freeze it at -238 degrees Celsius, 2) compress it at 20,000 PSI and lastly 3) absorb the hydrogen into a metal hydride.You can take a cylinder the size of a 12 gram co2 cartridge, fill it 80% of the way with a metal hydride and it will hold 12 liters of hydrogen. Anyway, I plan to use soda bottles, flexible plastic tubing (thick), and PVC/ABS pipe. You have that wrong. Think about a piston such as a bicycle pump, with a gas particle bouncing back and forth between the piston head and the opposite wall. It's decompressed by a valve at the source of use, such as a barbeque grill. I however doubt you have the means to do so. Cylinders for these gases are built to withstand higher pressures than normal cylinders. Google "Norway Hydrogen Highway" and "Scandinavian hydrogen highway partnership" to see what the rest of the world is actually "doing", not just fear-mongering about. In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. This will remove the outside casing. Similarly, if you let a gas expand, its temperature will drop, even if you have not removed any heat. It can be cut open using a good pair of wire snips. For me, the issue is to find a compressor to compress hydrogen, this is now the challenge. Storage of hydrogen in bottles is dangerous. The exaggerated fear of hydrogen gas storage and "embrittlement" is epidemically rampant! Use gloves and wash your hands with water when you're done. I store it to 15 pounds and run a gas generator on it and do it safely and have been for years. The propane tank won't reach a very high psi. Biomethane — refined biogas from anaerobic digestion or landfills — can be used. You can see that the pressure increases the more you compress the air (as the volume V decreases). https://www.youtube.com/watch?v=REV739pRNcw&t=25s. Here is a book I found, talking about magnets and their hydrogen absorbtion phenomena. im new at this kind of stuff and I was wondering how to turn methane has into a liquid is there an easier way than getting dry ice to lquify the gas, I don't really know about gas compression but I do have another answer to alternative fuel in a farm situation and that is a biomass gassifier it is proven technology and can be created with very easily there are a lot of resources for this but by far the simplest and most complete is the FEMA manual here is a link https://www.google.com/url?sa=t&source=web&cd=2&ved=0CDAQFjAB&url=http%3A%2F%2Fwww.woodgas.net%2Ffiles%2FFEMA_emergency_gassifer.pdf&ei=Bm9cUL2gJoK49QTKkoDoBQ&usg=AFQjCNHhq0oqOKhTIQSr0jrycS6MibI_AQ or you could just search for FEMA wood gasifier don't be fooled by the name though it can be used with almost anything that can burn, If PKM or anyone is still interested I would like to know what gas you want to compress -Methane whether it is flammable -Yes flammable how much you want to store what pressure you need to store it as what kind of tank or bottle and valve you have to store it with what it will be used for -from 25-120psi in a large gas (LPG) tanksI live in the Dominican Republic on a off the grid farm, my needs for low tec, cheap and ease of service is very high and important as I would like to show and share with others how to us methane as a fuel. Compressing a gas held at a constant temperature. Gas can be compressed much more easily than a liquid or solid. Yes hydrogen is both explosive if handled wrong and hence dangerous but by going through a risk mitigation process you can reduce this risk pretty much to zero (aka SAFE). I run a gas generator on this fuel to make free power and no electricity was used to make hundreds of liters. Right now, you are breathing in air – a mixture of gases containing many elements You just wouldn't be able to store much. Use the tractor for other things as well,run on methane. The hydrogen is released when you reach high temps, then you keep cooking it until the MH dries. To save on this loses we can compress the gas and sell it as bottled gas. Negative pressure the tank with a vacuum pump to -30lbs. When these "toxic gas" cylinders are involved in a fire, the area must be evacuated. An air compressor is designed to compress AIR, not natural gas. I don't think they are milking it properly (they are getting another company to recycle the used pellets) but hey, it's a step in the right direction. Compression Comprehension You can run 11:1 or even 12:1 compression on your pump-gas street motor, but you'll need this simple advie to make it happen. Synthetic fuels would have very low contamination levels and be of a hiughly uniform chemical structure. You cannot safely use an air compressor in natural gas service. Nothing can't be done if you have a pair! Hydrogen will still eventually weaken and destroy them. However, it is difficult, and the solids' capacity to be compressed is limited as their particles are already close together and … compress means to push down or smush together since the particles are extra far apart, when you compress a gas, the crazy movement of the particles slows down and the particles get closer together. :) re your post. For short term stationary storage, the old "gasbag" (balloon) technique is safest and loses the least gas. Purified hydrogen gas >99.5% is compressed well above 200 bar/~3000 psi and delivered in STEEL WELDING TANKS for everyday use from every major gas welding supplier known. Look forward to any help or advice.Thank you. i guess i can do same with bigger maybe cylindrical balloon (human size could be) and cook something. Hydrogen; maintenance of liquid state and the devices in order to do this requires an industrial MAZMAT type licensing and certification. Rinse wash and repeat till it equals out. Don't think you can get around this problem by using a thicker walled metal tank such as one designed for CNG or Acetylene. Why or why not? The main function of the compressor is to compress the gas … Really gets the imagination going.... http://www.treehugger.com/sustainable-product-design/is-a-hydrogen-powered-house-really-green.html. The composition of wood gas and the necessary fuel-to-air combustion ratio make storing wood gas uneconomical. Reply 0. http://hydrogenhouseproject.org/hydrogen-myths.html. Do you just make this up or are you paraphrasing (badly) some other source? Such firms as Quantum (partly own by GM) and Dynatek now sell filament-wound carbon-fiber tank lined with an aluminized polyester bladder instead of the TRADITIONAL SOLID METAL LINER.". This I have personally seen done. ok, this is getting more interesting... Materials to store hydrogen: www.sigmaaldrich.com/materials-science/material-science-products.html?TablePage=16375039. Peace and common fear mongerers..... work together to find a solution don't be a wet towel. Answer 2) The amount of space necessary to compress hydrogen far exceeds the capacity of a propane cylinder. Other applications are wood gasifiers & they can be junctioned in to run engine in emergencies ,can use all sorts of fuel sources. Gearhead318@hotmail.com is my email to order my hydrogen generator plans. Yet natural gas doesn't compress as easily. That is why the use of a metal hydride is mentioned so you can store vast amounts in a small space then chemically release the hydrogen when needed, by releasing into a secondary holding container to be used on demand. What happens if you take a gas and squeeze it into a smaller volume at a constant temperature? 1) hydrogen and oxygen explode so you would need to evacuate ALL oxygen from the cylinder. It is then safe to handle. How is the power capacity (kW or MW) of a biogas installation determined? If this fails! Could you store it in a a propane tank for a grill, or maybe a refrigerant tank? The forums are retiring in 2021 and are now closed for new topics and comments. Looking forward to perfecting my PEM cells. Think of others in your science project. CNG combustion produces fewer undesirable gases than the aforementioned fuels. The higher energy cost of production is offset by much lower energy costs in distribution and handling. 4 years ago. Methane is considered to be a non-compressible gas. I was getting 300 grams from Prius batteries using a metal saw to cut into the battery, separating the plates, and scraping off the MH. I ran a hose out of the check valve to hot-glued bottle cap where you attatch a plastic bottle of your gas. Then it maybe one of the following: If a gas spring has been lying in stock for a while, the seal with which the nitrogen gas is kept inside can stick to the rod of the gas spring, when this … I modified a $10 air compressor from radio shack in a similar way to drcrash did it here: https://www.instructables.com/id/convert-a-tire-inflator-type-air-compressor-into-a/instead of using the hose fitting he used, you should use a small check valve you can find at any pet store in the aquarium section arranged so that you can blow air into the compression area, and not out. 6 … That means that whatever the mix proportion between air and hydrogen, a hydrogen leak will lead to an explosion, not a mere flame. but why I cant use the extracted metal hydride as it is? In the gas state, widely-spaced particles move around randomly. If you gave more information, for instance - what gas you want to compress - whether it is flammable - how much you want to store - what pressure you need to store it as - what kind of tank or bottle and valve you have to store it with - what it will be used for then you might get a more helpful answer. This makes the use of hydrogen particularly dangerous in closed areas (tunnels, parkings)..[47] Some differences with common fuels include the fact that pure hydrogen-oxygen flames burn in the ultraviolet color range and are nearly invisible to the naked eye, thus it requires a flame detector to detect if a hydrogen leak is burning. I was thinking of running an engine with pure hydrogen, not hho. If people are intersted there are some hints above to follow and learn more. I'm working on a hydrogen gas system in tanks and it's not the "scary everything dies" story. In this video I explain how you can compress hydrogen in propane tanks. Liquefied Gases. H2 can be heated providing it is not mixed with O2. It is wise not to say "can't" in our evolving science, my friends. ", Answer They here speak about how we can store large amounts of $\ce{CO2}$ in depleted oil fields, natural gas reserves or other such underground storage reserves. You just have to know the dangers and put in the steps to protect yourself. However storage of H2 in solid array is stable and safe. Please check out my other videos. Wood gas can be compressed and stored in a tank. 3. it is composed of elements. Employed internationally offshore on rigs, here's a standard rack of STEEL H2 gas bottles compressed at 200 bar: You cannot, I repeat cannot compress hydrogen into a propane tank, period, end of story. "Intelligent Application in Material World Select Papers from IPMM-2001". This will produce a good amount of hydrogen which can be used instantly. Answer The work done in this case and hence the power required to run this type of cooled compressors is the theoretically minimum possible limit. The exaggerated fear of hydrogen gas storage and "embrittlement" is epidemically rampant! """Gorrie’s process took advantage of the difference between temperature and heat. There is no reason you couldn't. The only _viable_ low carbon way of making hydrogen fuel requires a very high temperature nuclear reactor and if you're going to do it that way you might as well just expend extra energy and tack on extra carbon atoms extracted from the atmosphere. Read the "Storage" section of http://en.wikipedia.org/wiki/Hydrogen_economy#Production.2C_storage.2C_infrastructure for ideas. Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). Removing oxygen from a tank can be done, and using a compressor you can get more than a small amount. Helium is indeed smaller, because H2, but Hydrogen can permeate materials and diffuse in materials Helium cannot because Helium is mostly non reactive. 6 years ago, can i storage on a big hard balloon and connect to a little stove heater just for a evening cooking ? This explains why you can compress gases and why they flow. A gas will fill any container, but if the container is not sealed, the gas will escape. In other words you would have to heat the hydride to get the H2 out.The reason hydrogen tanks and hydride hydrogen service has been found to be save in cars if due to the fact that hydrogen is much safer than gasoline. This is not something I'd encourage an amateur to attempt. Collect enough of it and you can fill a small cylinder.Be careful of the white film that separates the two plates, this is potassium hydroxide and works like an acid. http://hydrogenhouseproject.org/the-first-consumer-hydrogen-house.html. but it doesn't matter any more because i find out that its impossible to do it at home (at least for me). Hydrogen is extremely dangerous. Hydrogen must be remove from all oxygen making hydrogen an inert gas form.2. A certain amount of pressure, around 46 bars, is recommended for the methane gas. A liquid will take the shape of its container, but is hard to compress. You do NOT need an engineering degree to handle liquified gases, including hydrogen. If hydrogen is introduced into combustion chamber without oxygen mixture then it is inert until contact with oxygen, therefore none explosive till that O2/Oxygen contact point of gas mixture. Refueling stations already in use afford H2 refueling within 3 minutes employing high-pressure hydrogen gas. Many thanks John. However, gasifiers used to collect and condense wood gas for immediate use may prove valuable as a future alternative fuel source. This is why you can pour, but not compress, a liquid. The inside plate is the positive side (contains NOOHI and not very good for hydrogen storage) and the outside plate is the negative side, that's the one you want. Can you send me the quotation of your generator on "indradeep1989@gmail.com". 2. it is composed of large particles. More on that in 12 hours. Ah I should have read down before I commented about fear mongering. The report is from Rocky Mountain Institute. Can we explain what happens in terms of the gas particles? Also, I remembered this project in Island where they have hydrogen stations performing electrolysis, and running different car brands running on hydrogen. yes but buying oxenated air would be much more expensive sinse all i haveto do for hydrogen in put in some water and plug it in. Answer Ahh the danger of speaking in absolutes. Purified hydrogen gas >99.5% is compressed well above 200 bar/~3000 psi and delivered in STEEL WELDING TANKS for everyday use from every major gas welding supplier known. The most common method the days is reduction of natural gas (the Haber process), at a net 60% energy loss over the raw stock. If you expose dry NIMH powder straight from a battery, as soon as it loses the moister it bursts into flames. Why: Apart from being hard to contain (a propane tank would lose substantial amounts of gas straight through the walls), Hydrogen is _extremely_ reactive and makes metals brittle - especially steels. Turn on the compressor and let it compress the gas. 3) Did I mention it will explode?Now, do some research into storing your hydrogen in a metal hydride state. sorry my bad english. In this state, with a temperature approaching absolute zero, it would be liquid methane. At some point, the air particles are start bumping into each other more and more and the ideal gas equation starts to break down. But show it a leak, even minute, and it will find its way out. Do not attempt liquid or compressed gas storage, it is just asking for trouble. [60][61] Its Maribor counterpart, Marprom has 19 CNG city buses in their fleet, … This minimum possible power to compress a gas from P 1 to P 2 is given by following equation, Here subscripts 1 and 2 correspond to inlet and outlet states of the gas, V is the inlet volumetric flow of gas. If you're using HHO forget that, it has it's own oxygen in the mixture. If you want, you can have a look at the article World can ‘safely’ store billions of tonnes of CO2 underground on carbonbrief.org (accessed 2019-10-13). Apart from the handling issues mentioned above, hydrogen fuel must be made from _something_. Metal hydride storage of hydrogen is very safe and stable. From the first fuel cell design in 1801 (that's 214 years ago), much of this has been considered, designed, and tested. I can do anything!! If its hho gas you want to compress, its also very simple and its very dangerous!!!! Hydrogen is more volatile than gasoline, hence it wil dissipate faster than gasoline. Yes, but don't expect that balloon to last more than a day. Atmospheric pressure is normally about 101.4 kPa (14.7 psi). Therefore, do not ruin this new H2 application to further your fuel economy, please be careful and be certain hydrogen will not have any areas to pocket in engine compartment awaiting an ignition point explosive. Putting aside the CO2 emissions, bear in mind that large chunks of the pollution issues with both gasoline and diesel revolve around the issue that the fuel isn't "pure" octane or the same long chain hydrocaron (diesel is at least 30 different hydrocarbons plus contamination). Will it not react with water and become obsolete? Thus, compression, which is essentially forcing the gas particles closer together, has a great deal of space to reduce. Hydrogen requires super high compression to store efficiently in gas form. If you gave more information, for instance- what gas you want to compress- whether it is flammable- how much you want to store- what pressure you need to store it as- what kind of tank or bottle and valve you have to store it with- what it will be used forthen you might get a more helpful answer. I will keep posted on it... What I do is run my electrolosis cell for the hydrogen-oxygen gas, and store it in plastic bottles. i want to compress hydrogen or methane. Solids are generally defined as "incompressible," but it is actually possible to compress some to a very small degree. dried pellets made from hay or manure or wood chip or lawn clippings, lantana, coal. Then close the valve and rebuild pressure in the hydrogen tank that's connected to your hydrogen generator. lol. But it is not at all as dangerous as the myth want you to believe. L. The forums are retiring in 2021 and are now closed for new topics and comments. https://hydrogenhouseproject.org/index.html. Fun fun. Helium will actually diffuse far quicker than Hydrogen. I don't know if it's exactly 90PSI so I only go for around 40PSI max for me. I have been looking at this for a little while now, and digging into metal hydrides. Then hook it to your hydrogen tank from your generator. There are many systems that use a hot H2 environment.Neodymium and Samarium can also be used to absorb and store H2. Safeopedia explains Compressed Gas Liquefied gasses are liquid at normal temperatures when they are inside cylinders under pressure. They won't sell to anyone that does not have a business license or has a business designed for chemical storage. Hopefully get a doctorate out of it. Hydrogen partially makes up for that fact by being more energy dense per unit mass — about 3 times as much as natural gas. (Think about a diving tank – 600 L of gas is compressed into a 3 L cylinder.) Best Answer If you really must use hydrogen then make it as you need it. Don't be such a "STOP DANGER" monger.
