How much resistance is there in making an electric motor spin so it generates electricity? Idiots. , 4 Ways to Make Hydrogen Gas at Home or in the Lab, Free Printable Periodic Tables (PDF and PNG), Electrolysis of Water and the Concept of Charge, List of Electron Configurations of Elements, Periodic Table For Kids With 118 Elements. You simply continue to fill your storage tank or, if necessary, get a bigger tank. Dont use metal or plastic because the drain cleaner could react with the metal. (Or a fuel cell that works with any other energy feed molecule which we can conveniently produce), I REALLY dont want to stop by the hydrifen stations and buy a product to enable my transportation. Why dont you just make stronger alternator that way people can can make their own hydrogen fuel in their cars and they would only have to use water and they wouldnt have to pay for it. Its quite obvious the #1 atom on the chart is the most important. What will be the concerns when we have excess hydrogen from storage containers all over the place, especially cars. Personallymy money is on the unicorn farts.The only real alternative to carbon fuel is nuclear.Unfortunately, thanks to the Luddites that seem to make up the majority of the dumbmasses, nuclear is not really an option.Fortunately, we have a virtually unlimited supply of carbon based fuels, and after the current hysteria over carbon runs its course well get back to making the planet a better place with carbon based fuels. The refuelling could be done in a matter of minutes as compared to hours in the case of lithium-battery powered electric cars. 
Its a much harder build but worth it. None beats the H2/Air fuel cell at about 50%. The ports targeted under TNPAs renewable energy program include Port Elizabeth, Ngqura, East London, Mossel Bay, Saldanha Bay, Cape Town, Durban and Richards Bay. The reason you want water in the container is so you can collect hydrogen without obtaining air. The problem has been to find materials that can meet the rigorous demands encountered when steam reaches 600 degrees. Cost savings and been down the road with energy retailerswho take advantage of every political and financial blip to bend is over and scalp the public of more money. The graphite makes good electrodes because it is electrically neutral and won't dissolve during the electrolysis reaction. A new Columbia University AI program observed physical phenomena and uncovered relevant variablesa necessary precursor to any physics theory. What Is Battery Acid? It does not say if the process is scale-able to produce large quantities which is currently the biggest issue with all break-thoughts in energy production. 
I myself have got a lawnmower to run from an hho generator that i built from watching youtube videos 8 years ago. I almost want to apologise for posting a comment here, but I truly appreciate any source that can potentially increase science knowledge and understanding.I also hope that its no to absurd for me too hope that folks will research and truly think about issues before posting about them.I fear that we have long ago crossed that [unwritten] rule/prerequisite.. What is the benefit of converting Hydrogen into Orthohydrogen with 42.8 kHz PWM ??? Insert the pencils through the cardboard so that the lead is submerged in the liquid, but not touching the bottom or side of the container. It would be suicide not to. As for the universe, its all indefinitely moving. I have never seen anything published with regards to safety with a hydrogen energy infrastructure. Compared with batteries, our process consumes much smaller volumes of raw materials in relation to the amount of energy that is stored,"says Vllestad. 
That only works for suburban and rural people, I know.
Please use a nice languate, Mark. Hydrogen and wind, however much there is available at night, is the only way, aside from nuclear, that can facilitate the excising of fossils from our energy mix. SMH at sam harris losers again online. Place the other ends, not touching, into a container of water. This is not a very complicated process, but the extra work means that the plant units have to be larger. Low emission hydrogen generation through carbon assisted electrolysis.. I disagree, however, that large-scale creation and storage is the way forward. We all understand the article within its context, so why does it seem that you cannot understand? Op-Ed: Unequal Distribution of Profits May Be Fueling Port Strikes, BP and Iberdrola Partner for Hydrogen, Ammonia and Methanol Production, South Africas Ports Authority Explores Investment in Renewables, Coast Guard Investigating Laser Strikes During Buffalo Rescue Missions, Mixed proton and electron conducting double perovskite anodes for stable and efficient tubular proton ceramic electrolysers., Fincantieri Delivers Prototype Cruise Ship to Norwegian Cruise Line, Drought Threatens Major Rivers in the U.S. and Europe, Royal Navy Buys a Commercial Crewboat for High-Tech Testing, First Solid Form Hydrogen Propulsion Vessel Ordered for Amsterdam, Interview: Nicholas Bourque, CSO of OneOcean, Opinion: "Narco-Drones" Are Here, and Our Maritime Laws Aren't Ready. ThoughtCo. He could not pulse some juice hundreds of thousands of times a second like we can today. Hydrogen is the future.
Collect the hydrogen gas by inverting a water-filled tube or jar over the wire producing the hydrogen gas. The 2 tanker versus 1 tanker I am not sure about. Is this really useful in a sustainable energy scenario? No, that was shown impossible 500 years ago.
If research is to be applied in practice, it must be possible to run the process at larger scales. How about grid storage? They began with a list of 120 materials that they believed might be suitable for different aspects of the process. Make a Storm Glass to Predict the Weather, Experiment With Fruit Ripening and Ethylene, Grow Table Salt or Sodium Chloride Crystals, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College. Nothing bad will happen if it does, but the resulting air-hydrogen mixture is much more flammable than hydrogen on its own because it now contains oxygen, which will act as an oxidizer.
Get past the scientific whateverybody says crap and ridiculous social entertainment, and well get somewhere.k im done.peace/happy new year. Brian Gicheru Kinyua. The designer has had his technology validated by two universitys and partnered with the manufacturing company in 2019. Two recent incidents of lasers being pointed at U.S. Coast Guard boats while in operation on the Great Lakes are currently under investigation. The reaction is exothermic, so use a glass bottle (not plastic) to collect the resulting gas. UNSW School of Chemistrys Professor Chuan Zhao says in water splitting, two electrodes apply an electric charge to water which enables hydrogen to be split from oxygen and used as energy in a fuel cell. Heat produced by the reaction could damage plastic. The efficiency of water electrolysis is currently about 75-80% using Pt as catalyst. Cap or seal the container before inverting it, to avoid exposure to air. Publication in such a prestigious journal takes time, and the work has advanced considerably since the paper was submitted. Fuel transportation is likewise complicated by the need to move and store hydrogen gas at high pressure. By selecting hydrogen you still only require one pipe. It just so happens so conveniently that H is massively coupled with Oxy in a substance that covers 70% of our spinning rock. The research that has resulted in the BGLC material has now been published in the June edition of the journal Nature Materials. Hydrogen-powered cars may soon become more than just a novelty after a UNSW-led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them. Prof Zhao says that if the water-splitting technology is developed further, there could one daybe hydrogen refuelling stations much like petrol stations today where you could go and fill up your hydrogen fuel-cell car with hydrogen gas produced by this water-splitting reaction. Power in is always lower than power out Wrong way round. Once youve identified the hydrogen source, you can collect it. "Now that we pay more attention to renewable energy, the focus has intensified.". There is no doubt that a market exists and that steam electrolysis is interesting if we can succeed in maturing the technology at the right price," says Vestre. Good batteries could put this out of business. By clicking Accept All Cookies, you agree to the storing of cookies on your device to enhance site navigation, analyze site usage, and assist in our marketing efforts. Shows a dry-cell used tho, which is a cheap easy to build but in-efficient design that produces gas, cuz all these dry-cells immediately have current leakages as the water/gas mixture rises and connects at all the holes in the neutral plates, but it wont so much if you can somehow keep the fluid below the holes, but usually you cant see inside a dry-cell cuz of the gaskets used between the plates. We have manufactured the pipes that will be used, making the system entirely scalable,"says Vllestad. Keep up with the latest scitech news via email or social media. Battery (could go as low as 1.5V, since there is an electrolyte), 2 Paperclips or pieces of electrical wire. Place the other ends, not touching, into a container of water. (October 5, 2018). But you only need one pipe to generate the same amount of energy that would require several batteries. For this reason it is more important to store energy generated during peak production days, and use it when demand exceeds production. It is probably no cheaper to manufacture a pipe of this type than to produce a battery. The hydrogen will come from the metals and not water!because water is not H20! This method employs electrolysis, which breaks water into hydrogen and oxygen gas. Bit I am one of those. It pays off, because heat is cheaper than electricity. Be aware that mixing hydrogen gas with oxygen or air (which contains oxygen) increases its flammability because oxygen is an oxidizer. Do you have more information about this? An additional benefit is that our nickel-iron electrode can catalyze both the hydrogen and oxygen generation, so not only could we slash the production costs by using Earth-abundant elements, but also the costs of manufacturing one catalyst instead of two.. 2H2O to 2H2 + O2 is never energy efficient. Hydrogen has to be highly compressed which takes a LOT of energy. Jul 29, 2022 9:29 PM by Regarding charging time, most pundits are anticipating that instead of charging the battery in the vehicle, the battery itself will be swapped at a refuelling station in a matter of minutes the technology to position a car precisely over a changing port, unclip and lower the existing battery then reverse the process for a new one is relatively simple to implement. Uuuhhhh To start with the obvious, no energy is created. Ixnay on energy cpanus powering personal transportation, because I guarantee the petroleum companies , whove all changed their names to energy companies, are behind the push for a hydrogen economy so they can profit off our need for transportation, Everyone seems to forget the fact that hydrogen burns. This sounds interesting! What we have done is to replace some of the barium in the original material with more lanthanum with the simple objective of making it more basic,"says Vllestad. UK is the latest country teetering on the edge of a potential port strike. This could severely affect shipping at Felixstowe and Liverpool, two of UKs major ports. Why do you think a small black camera roll with a drop of water in it explodes/pops instantly in a microwave.H-305k btu/gallon (not man made)Gasoline-115k btu/gallon (man made with hydrogen/carbon)Diesel-130 btu/gallon (man made with hydrogen/carbon)Water is the definitely the answer. Store hydrogen gas away from an open flame or another ignition source. Iron and nickel, which are found in abundance on Earth, would replace precious metals ruthenium, platinum, and iridium that up until now are regarded as benchmark catalysts in the water-splitting process. Pulsed DC (high frequency) changes the atomic structure of the H atom, its not about the output volume, its about the atomic quality of the gas. Battery swapping for vehicles (I published that concept over 20 years ago) wont happen especially at this pioneering stage. The Maritime Executive. Raising it to 90% is really not going to make a significant difference. Just more rainbows and unicorn farts. Much better to charge with my own solar panels. Ed, we would like to work this out with you. Place the cardboard over your container of water. To date we have made measurements in a single pipe for more than 700 hours, but at industrial scale you have to construct a system consisting of a hundred, a thousand, or perhaps ten thousand pipes.". They now have the first electrolyser that works efficiently using pressurised steam and that can be scaled up for use in industrial processes. Aug 23, 2019 1:58 PM by These are all good ideas but not necessarily practical everywhere. The volumes of available solar, wind and wave energy vary throughout the year. It was already done alongtime ago and still being done. And why? The nanoscale interface fundamentally changes the property of these materials, he says. zinc granules (or iron filings or strips of aluminum), aluminum (included in the drain removal products or you can use foil).
Connect each wire to a battery terminal. Insert the pencils through the cardboard so that the lead is submerged in the liquid, but not touching the bottom or side of the container. The 83% efficiency is based on the single process of h2o broken into [2x] h2 and o2. What we do is coat the electrodes with our catalyst to reduce energy consumption, he says. This means that less electricity is needed to get the reaction to take place, making the hydrogen generated more competitive in the market. She has taught science courses at the high school, college, and graduate levels. Helmenstine, Anne Marie, Ph.D. "How to Make Hydrogen Gas Using Simple Materials." Congratulations! Back to school and start again. Jul 29, 2022 9:15 PM by Now you may become efficient in the night power grid at low use times but is still expensive and will never be cost effective. Vllestad and Strandbakke are currently working on an EU project involving research experiments at entirely different temperatures. No one seems to mention this problem.There is already a vast infrastructure to cater for hydrogen. Hmm how comvenient IS that? One item that people are forgetting is that hydrogen is not as energy dense as a petroleum product. Were hoping our research can be used by stations like these to make their own hydrogen using sustainable sources such as water, solar and these low cost, yet efficient, catalysts., Reference: Overall electrochemical splitting of water at the heterogeneous interface of nickel and iron oxide by Bryan H. R. Suryanto, Yun Wang, Rosalie K. Hocking, William Adamson and Chuan Zhao, 6 December 2019, Nature Communications.DOI: 10.1038/s41467-019-13415-8. A quick glance at todays metal prices shows just why this could be the gamechanger needed to speed the transition towards the so-called hydrogen economy. Not exactly life changing is it? Utter drivel. *some of the following is not in order, relating to comments above*.
Helmenstine, Anne Marie, Ph.D. (2020, August 27). In the industrial sector, Vllestad highlights steel manufacturing where large amounts of heat are required in the production process. Internal Combustion Engines need to be cooled. https://www.sciencedirect.com/science/article/pii/S1110016815001714. Methanol can also be directly used in an ICE vehicle. Doesnt all this speculation ignore the fact that the LEAST efficient way to move something around is to light it on fire? The water molecule is a basic configuration and it is hare to see how we could split it much more efficiently than we do now. Secondly, storage and leakage of hydrogen from storage will be a key problem. The research results were published recently in Nature Materials in an article titledMixed proton and electron conducting double perovskite anodes for stable and efficient tubular proton ceramic electrolysers.. This is where hydrogen can be split from oxygen and captured as fuel, and the oxygen can be released as an environmentally-friendly waste.. Unbend the paperclips and connect one to each terminal of the battery. It also has to be kept at a very low temperature to keep from boiling off. This would be a great optionFor trains,planes,boats,andTrucks . Thehydrogen bubbleswill burn; the oxygen bubbles will not burn. Not sure, but looks like you Sci-Tech guys are using 7 cells with your testing anode/cathode neutral plates in the middle with +/- on each end plate, but if your electrolyte connects in anyway from cell to cell, which it looks like it is with the hole-tube manifold connections, then your wasting current right thru the fluid from end to end. I learned it simply from guys online 15 years ago, and its very easy to do with a 12v car battery. Brian Gicheru Kinyua, Published See the Trillion dollar question, as my latest article/post.I am one of the 1st to see how plasma could explode the water molecules.that was way back in the late 1970s. Might work on a train with all the wheels available it might be possible. This is not H2 it is also O2 which is rocket fuel. Familiarize yourself with the safety information for any chemicals you may use. Beyond that, high pressure refueling is not for the casual, lackadaisical types often found at gasoline pumps. They are using steam instead of liquid water to generate the hydrogen. However, it is not sufficient simply to demonstrate this in a small laboratory. and the wiki is perdy cool too, except for the bs at bottom, that someone shud remove.https://en.wikipedia.org/wiki/Oxyhydrogenhahaaa first welding gas ever used! Ted-san and Daniel point out the gaps in this article, but we still lack an understanding of production rates, actual efficiencies (what does 83.7% actually mean?) It is unpleasant to read your impolite outbursts. Id even contemplate including regenerative energy collection from the weight of the battery being lowered into the swapping well! Thats the problem with being stationary around a center axis of gravity, you believe that everything is still, when in fact its all moving. Disconnect the battery. Compared with batteries, our process consumes much smaller volumes of raw materials in relation to the amount of energy that is stored." But if you want to store the same amount of electricity for 24 hours, you need 24 batteries. In issuing the call on Monday, TNPA said the RFI process would allow it to understand the renewable energy market. They like to forget the massive costs of infrastructure and energy usage making the components. https://rubenscamejo.wordpress.com/2019/11/26/letter-sent-to-every-mp-in-the-federal-parliament/. Not to MENTION what they do to our political system with their coffers of cash.
Some are even faster.
There are still many steps that have to be optimised and developed further,"Vllestad interjects. Ok so reading this article seems to me that if we really what to use this very old tech which has been around for years can be done quite easaly if we really want to as a spices.
Theone with more bubblesis giving off pure hydrogen. Many believe that electric vehicles are totally clean, forgetting that the electricity has to be generated by some means somewhere. Energy majors BP and Iberdrola announced plans to form a new joint venture designed to help in the acceleration of decarbonization of transport and industrial sectors. Air contains 20% oxygen, which you want to keep out of the container in order to keep it from becoming dangerously flammable. Heres a good one.. a simple HHO velocity google search gave this link. We would like to work with you on that one. We are now eighteen months into a new EU project in which we are working to meet the next raft of challenges,"say Vllestad and Strandbakke. On this catalyst there is a tiny nano-scale interface where the iron and nickel meet at the atomic level, which becomes an active site for splitting water. Materials are great research, but nothin beats good ol stainless steel plates and a simple PWM (12Volt Pulse Width Modulator) ($30 ebay) and 42.8kHz, generates Orthohydrogen not Parahydrogen. All this sounds expensive, but in reality the economics are sound. Collect the hydrogen gas by inverting a water-filled tube or jar over the wire producing the hydrogen gas. By University of New South Wales You can test which gas is hydrogen by holding a lit match or lighter over the container. Development time lines for almost all energy-related technologies are long,"says Per Vestre, who is Managing Director at CoorsTek in Norway. Oxygen Evolution ReactionThe Enigma in Water Electrolysis., Giddey, S.; Kulkarni, A.; Badwal, S.P.S.
document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); SciTechDaily: Home of the best science and technology news since 1998. This is where materials scientists Vllestad and Strandbakke enter the stage. This technology can be cost effective without being particularly energy efficient. When the ultimate source of energy is free (solar, wind,..) and the process is nonpolluting all that matters is cost to build/maintain and sale price/value of hydrogen against fossil fuels.Inefficiencies in the process just produce heat as a byproduct. In other words, a perfect process would be 100% efficient with no waste (or heat loss).That actually seems like a moot point, since close to 90% efficiency has already been realized. The heat contributes to the reaction and at higher temperatures the catalytic activity is much greater,"say the researchers. An ethanol fuel cell would be more useful. You dont have to use noble metals.".
"Many years passed between the invention of the lithium-ion battery and its current application in millions of cars.". That way it would be a carbon neutral fuel using an infrastructure that we already have. Basically everything is wonderful in small scale but when they try to scale up it becomes impossible or prohibitively expensive. Norwegian scientists have developed a material which can make hydrogen from water vapor, instead of liquid water. Were talking about low temperature electrolysis. Collect the gas as before, in a container that has been filled with water. Attach a wire to each pencil and connect it to the terminals of the battery. Maybe the water could even be recycled if a fuel cell is used for the reverse conversion to electricity. Attach a wire to each pencil. (2015). 42.8khz = 4x energy potential. This is another lab results article of nano size reactions. Interestingly, the port strikes have spread to countries like Germany, where they have not occurred in the last three decades. Thats why you can never find a beginning and will never find an end.
by The article doesnt mention it but the authors report an extremely high efficiency of 83.7%, as well as a higher current density than with platinum. Place drain cleaner and aluminum in a glass dish. I work with solar concentrator solutions and we are experimenting with creating H2 out of water. It is probably no cheaper to manufacture a pipe of this type than to produce a battery. The biggest problem with hydrogen is that it is a gas which requires huge energy to compress or liquify. Using gaseous hydrogen directly, either as a cell fuel or in a ICE is fraught with problems, not the least of which is the need for very high pressure storage (2000-3000PSI) tanks. There are certainly pros and cons to Hydrogen, but its going to have to be more convenient and more efficient/less expensive than direct electric charging or its solving a problem that no longer exists. They are asking for the public to report anything they see or provide tips on the recent incidents. The salt is helpful because it dissociates into ions which increase the current flow. "The most frequently applied method of doing this remains the same as that carried out at the Vannstoffen hydrogen factory at the Vemork power plant in Telemark a century ago, explain Einar Vllestad and Ragnar Strandbakke. Unfortunately, it does not address a few key points that make it an unattractive option. By contrast, ruthenium, platinum, and iridium are priced at $11.77, $42.13 and $69.58 per gram in other words, thousands of times more expensive. Just a thought. The method has become better, cheaper and more efficient, but still requires a lot of energy. This is where hydrogen can be split from oxygen and captured as fuel, and the oxygen can be released as an environmentally-friendly waste.. First, to be stored, it must be compressed to be stored, which costs energy and reduces it economic viability. At higher temperatures and greater catalytic activity, we no longer need these expensive materials to complete the reaction," he says. Remember that the AvGas fuel tank is simply included as part of the aluminium (or other lightweight material) wings and belly of a commercial aircraft and lined with an impervious layer that wouldnt work for Hydrogen. You combust it with oxygen and you have water. Stopper or cap the container of water and gas before turning it rightside-up. In particular, hydrochloric acid (. There are two simple improvements you can make to improve the efficiency of hydrogen gas production. The Maritime Executive, Published So we finally decided to select this material and tweak the chemistry a little, he says. Heat is much less expensive than electricity,"says Vllestad. When you need to produce energy, you reverse the entire process by reintroducing hydrogen and generating energy and water. The company CoorsTek Membrane Sciences, which is participating in the project as an industry partner, is well aware that this will not happen overnight. Store hydrogen gas away from open flames, heat, and ignition sources.
