Hydrogen’s Recent Ascension as Fuel for Future Electric Cars

Effie P — Wed, 27 Feb 2019 13:17:04 +0000

Fuel cells produce electrical energy directly from the chemical potential energy that is stored in H2 and O2 molecules. Using a Proton Exchange Membrane (PEM), the unit needs only to be supplied with pressurized H2. Fuel cells are inherently more efficient and reliable than combustion engines, and their only by-product is water. These advantages make […]

How Hydrogen Can Become the Fuel of Choice in the Future

Arsenij Percov — Thu, 26 Jul 2018 19:39:29 +0000

The idea of using hydrogen fuel as an energy source is amazing since it doesn’t produce any pollution. However, producing pure hydrogen from water (the only clean way to do it) requires more energy than it will generate. Hydrogen fuel can be used as storage The solution to the problem mentioned above is using hydrogen […]

Controlling Electron Spin to Improve Hydrogen Production Efficiency

Ece Polat — Fri, 03 Feb 2017 20:19:57 +0000

During hydrolysis, water is split into hydrogen and oxygen gas; however, during this process hydrogen peroxide forms too. As a byproduct, hydrogen peroxide intervenes with the reaction rate. The production of hydrogen peroxide is due to the spin of electrons. Thus, the Eindhoven University of Technology and the Weizmann Institute researchers found the way to […]

Modified Enzyme May Bring Affordable Hydrogen Fuel One Step Closer

Samantha Joe — Wed, 06 Jan 2016 18:48:21 +0000

Hydrogen has high potential to fuel vehicles, but as pure hydrogen does not exist naturally, it must be derived from other compounds that contain hydrogen. Researchers have been able to make headway on the journey towards taking hydrogen fuel from water, and now in a cost-effective way. Hydrogen fueled cars have not been able to […]

Hydrogen Fuel Cars Focus of Department of Energy Grant

Annika Tostengard — Sat, 10 Oct 2015 19:24:07 +0000

One of the major factors holding back hydrogen cars up until now has been storage. There is currently no economical way to store the gas onboard a vehicle. However, the Lawrence Livermore Nationa Laboratory aims to solve this problem as part of a tri-lab consortium working on new materials and tools to make hydrogen fuel […]

Toyota to Produce Hydrogen Fuel from Cow Dung

Sarah Higman — Tue, 05 May 2015 10:53:56 +0000

Toyota engineer Scott Blanchet has been working on a new car engine – one that is powered by cow dung. Exploiting a waste product to harvest the universes most abundant element hydrogen is the plan. Toyota will extract the hydrogen out of the manure using large digesters; essentially lagoons where the dung is broken down […]

Hydrogen from Corn Waste Obtained at Virginia Tech

Anthony Petrolo — Fri, 24 Apr 2015 12:47:06 +0000

US scientists have recently developed a hydrogen fuel cell prototype battery, produced in a more rapid and cost-effective manner, and utilises organic content to facilitate electrolysis. This will play a vital role in fast-tracking a transition to cleaner and more energy-efficient renewable fuels. Professor Percival Zhang, his research team at Virginia Tech’s Department of Biological […]

First Commercial-Scale Solar Hydrogen Fuel Generator Opens in UK

Benji Jerew — Tue, 11 Nov 2014 15:03:06 +0000

Hydrogen fuel can indeed be produced via electrolysis, which requires connection to some kind of power source, be it a coal-fired power plant or an array of solar panels, and this raises a question… “Renewable energy, such as wind power and solar power, are typically intermittent, so how can they be used as a reliable […]

Makes Its Own Hydrogen Fuel – Mercedes-Benz Vision G-Code Concept

Benji Jerew — Mon, 10 Nov 2014 21:35:26 +0000

Unveiled at the opening of the Beijing Product Engineering Centre, the Mercedes-Benz Vision G-Code Concept looks like most any futuristic vehicle, except that, even paint-deep, this isn’t any ordinary hydrogen fuel vehicle. You’ll note, for starters, that it would be entirely incorrect to call the Mercedes-Benz Vision G-Code a hydrogen fuel cell vehicle. Like hydrogen […]

Solar Powered Hydrogen Fuel – The Rebellion

Benji Jerew — Wed, 18 Jun 2014 16:07:25 +0000

Hydrogen fuel cell and battery electric vehicles have one very important thing in common: they’re both emissions-free sort of. While it’s true that hydrogen fuel cell and battery electric vehicles do not generate any emissions in themselves, their upstream emissions cannot be ignored. Really, it all depends on where the power grid gets its electricity […]

Recycling – Human Waste to Hydrogen Fuel

Benji Jerew — Fri, 21 Feb 2014 17:23:16 +0000

As hydrogen fuel cell vehicles get closer to production, refueling stations are going to be needed. For fueling stations, of course, a fuel source is necessary. While the gasoline and natural gas infrastructure is fairly ubiquitous, hydrogen fuel infrastructure is still somewhat behind. Some suggest that the existing natural gas network could be used, while […]

Japan’s Hydrogen Fuel Infrastructure is World’s Most Advanced

Benji Jerew — Wed, 22 May 2013 19:20:26 +0000

As automakers gear up to release even limited numbers of hydrogen fuel cell vehicles, perhaps the biggest struggle will be getting infrastructure in place. Electric vehicles have pretty much the same problem right now, with limited opportunities for fast charging on the road. Efforts are well under way, but this is mostly on the part […]

Nanosize Silicon Found to Generate Hydrogen Efficiently

Benji Jerew — Thu, 24 Jan 2013 07:33:26 +0000

The science of nanotechnology, specifically nanomaterials, has grown by leaps and bounds in the last decade, and scientists are discovering more material characteristics than they ever could have before, just examining macromaterials. For example, when silicon [Si] oxidizes with water [H2O], it gives off hydrogen gas [H2], leaving a layer of silicon dioxide [SiO2]. While […]

Artificial Photosynthesis Could Generate Hydrogen Fuel

Benji Jerew — Tue, 22 Jan 2013 18:42:38 +0000

Hydrogen could be the perfect zero-emissions fuel, if only the generating process could eliminate its carbon-footprint. There are a couple of ways to produce hydrogen for use in hydrogen fuel cell or even internal combustion engined vehicles, but they are not without their quirks. Electrolysis splits the hydrogen and oxygen from water molecules, but unless […]

New Vanadium Oxide Fuel Cell Can Both Generate and Store Energy

Maria Reyes — Mon, 09 Jul 2012 14:04:28 +0000

It is now entirely possible for electrical gadgets to keep on running after fuel is depleted. Materials scientists at Harvard have developed a solid-oxide fuel cell (SOFC) that uses hydrogen as fuel to generate electricity, but can store electrochemical energy like a battery as well. Recent advances in low-temperature operation allowed the thin-film SOFC to […]
