A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

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 UT Austin technique is aimed at the latter.

U Oregon team advances effectiveness of catalytic water dissociation in bipolar membranes

Green Car Congress

Researchers at the University of Oregon have advanced the effectiveness of the catalytic water dissociation reaction in bipolar membranes. The technology behind bipolar membranes, which are layered ion-exchange polymers sandwiching a water dissociation catalyst layer, emerged in the 1950s. —Oener et al.

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

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.
