New Catalyst for Electrolysis Reduces Costs by 97% and Increases Hydrogen Production Fourfold

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.

Electrode Surface Texture: Key to Using Less Platinum in Methanol Fuel Cells

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).

Dealloying Process Creates More Efficient and Cheaper Platinum for Fuel Cells

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.

On-Demand Hydrogen Production System for Commercial Use Released

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).

Energy-Efficient Way to Produce Hydrogen from Noise and Vibrations

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.
