Buoyancy Drives Hydrogen Convection For Mass Production
December 15, 2020 | Leave a Comment
A Helmholtz-Zentrum Berlin team has now presented a method to visualize convection in the electrolyte and to reliably simulate it in advance with a multiphysics model. Hydrogen produced by using solar energy could contribute to a climate neutral energy system of the future. But there are hurdles on the way from laboratory scale to large-scale […]

The Bubbles That Hold Back Hydrogen Production Studied
January 8, 2020 | Leave a Comment
Helmholtz-Zentrum Dresden-Rossendorf researchers’ laboratory experiments and a parabolic flight campaign have enabled an international team of researchers to gain new insights into water electrolysis, in which hydrogen is obtained from water by applying electric energy. Water electrolysis could play a key role in an energy transition if efficiency improvements can be achieved. The findings offer […]

20 Times More Hydrogen Produced With New Catalyst
December 18, 2019 | Leave a Comment
Eindhoven University of Technology (TU/e) researchers have now developed a pure platinum alternative with a 20x higher activity. It is a catalyst with hollow nanocages of an alloy of nickel and platinum. Working together with Chinese, Singaporean and Japanese researchers, TU/e researcher Emiel Hensen wants to use this new catalyst to develop a refrigerator-size electrolyzer […]

Tungsten Suboxide Improves Platinum Making Hydrogen
November 19, 2019 | Leave a Comment
Korea’s Advanced Institute of Science and Technology (KAIST) researchers presented a new strategy for enhancing catalytic activity using tungsten suboxide as a single-atom catalyst (SAC). This strategy, which significantly improves hydrogen evolution reaction (HER) in the metal platinum (pt) by 16.3 times, sheds light on the development of new electrochemical catalyst technologies. The research group’s […]

Doubling Hydrogen Production Using Sunlight
May 14, 2019 | Leave a Comment
Princeton University engineer’s research has harnessed sunlight to isolate hydrogen from industrial wastewater, doubling the previous standard for splitting hydrogen from water in a scalable way. Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. In a paper […]
