Hydrogen Production: Photocatalytic Water Splitting or Solar-Electrolysis?

Recently, a paper was published in Nature (doi.org/10.1038/s41586-021-03907-3), demonstrating a 100 m2 array of panel reactors to produce hydrogen from water under the sun. Hydrogen is an attractive and versatile energy carrier, which can be produced from water through photocatalysis using sunlight, and through electrolysis driven by solar or wind energy. Photocatalytic water splitting reaches notably lower conversion efficiencies of … Read More

Record Water Electrolysis Efficiencies

Panasonic Researchers Reach Record Efficiencies With Sustainion® A group of researchers at Panasonic Corporation, Japan recorded an energy conversion efficiency of 74.7% for an alkaline water electrolysis cell flowing 1.0 A cm-2 in 1 M KOH at 80 °C. The use of NiFe based cathodes was enabled by using our base stable anion conducting Sustainion® membrane and the corresponding results … Read More
