Purdue University chemical engineers have invented a method of storing hydrogen and releasing it safely without the need for high-pressure tanks, only by using the fuel cell’s dissipated heat.
Hydrogen fuel cells generate electricity when fed with hydrogen, which combines with oxygen and results water. Still, hydrogen fuel cells are expensive due to the catalyst used in the cathode for the reaction known as oxygen reduction. That catalyst is 100% pure platinum, which is a rare and expensive material.
India’s largest bus manufacturer, Ashok Leyland, is going to implement a 6-liter engine that will run on clean natural gas (CNG) enriched with hydrogen, making it the first bus powered by an internal combustion engine aided by hydrogen.
Dr. Georgia Antonopoulou, a biochemical engineer from the University of Patras in Greece, has discovered that whey coming from cheese factories can be used by cultures of bacteria contained in microbial fuel cells to generate electricity. Whey is a lactose-rich organic material, and it is usually disposed.
Fuel cells are indispensable for hydrogen powered cars, and it looks like hydrogen may be the ultimate energy storage that meets all the demands of a clean “fuel” (though it’s only a carrier, not a fuel). Fuel cells, are expensive, though, and their price is due to platinum, which is a rare metal.
Hydrogen, the cleanest energy storage in the Universe, is most of the time associated with high costs, although it is extracted from water, which is the cheapest yet the most precious element to life. Extracting hydrogen from water is done through a method called electrolysis, but doing electrolysis efficiently requires the usage of catalysts such as platinum, which is very expensive.

A team of researchers from the Lawrence Berkeley National Laboratory and the University of California, Berkeley, has discovered a catalyst metal 70 times cheaper than platinum for use in electrolysis systems, to generate hydrogen from water.
MIT researchers, along with their colleagues from the Brookhaven National Laboratory and the Japan Institute of Science and Technology have found a method of decreasing the amount of platinum used in DMFCs by increasing the efficiency of the fuel cell’s electrodes. Others have tried to replace the platinum on the cathode with a liquid regenerating catalyst system (catholyte solution).
Fuel cells are usually expensive because they use platinum as a catalyst. To make them more appealing to the market, researchers from the DOE’s National Accelerator Laboratory and the University of Houston, have created a new type of platinum catalyst, reducing the use of the pure metal down to 80 or even 70 percent, thus reducing the overall cost.
Vitalij Pecharsky, a researcher from the U.S. DOE – Ames Laboratory, along with his team, studies the possibility of storing hydrogen at room temperatures, in a recyclable container – just like your car’s reservoir.
A team of researchers from the MIT, led by Professor Angela Belcher, used a modified virus as a biological scaffold for assembling the nanoscale components needed to split water into hydrogen and oxygen. The bacterial virus is called “M13″, and it’s said to be harmless.
eHydrogen Solutions, a company specialized in the development of on-demand hydrogen power stations, issued a press release announcing that they launched the “H2-Reactor Development Project”. The H2-Reactor uses water as the hydrogen source, is self-contained and has an alloy of aluminum or magnesium as the reactive material (to get the hydrogen out of the oxygen bond).
A team of researchers from the University of Wisconsin-Madison have just discovered that crystals of zinc oxide, if submerged, absorb its vibrations and act like a piezoelectric material, developing areas of strong negative and positive charges.
Researchers at the University of Wisconsin-Madison have found a new way to produce hydrogen by using ambient noise to turn water into usable hydrogen fuel. The process harvests small amounts of waste energy in the form of stray vibrations and noise from the environment to break the chemical bonds in water and generate hydrogen and oxygen.
