Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels. —Jun Lou.

Scientists at Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) have developed a new coordination polymer glass membrane for hydrogen fuel cells that works just as well as its liquid counterparts with added strength and flexibility. Adding zinc to this liquid led to the formation of a solid, elastic polymer glass.

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

A multi-institutional team led by the US Department of Energy’s (DOE) Argonne National Laboratory (ANL) has developed a low-cost cobalt-based catalyst for the production of hydrogen in a proton exchange membrane water electrolyzer (PEMWE). Production of green hydrogen at that cost could reshape the nation’s economy.

volts (V) of water-splitting voltage with its novel low-cost electrolysis technology. The theoretical minimum voltage needed to split water molecules into hydrogen and oxygen is 1.23 Nanosystem for water electrolysis. This lowers the system cost of what is essentially an electrolysis process. HyperSolar, Inc.
