electrolyzers

An international team from the University of Adelaide, Australia, Tianjin and Nankai Universities in China and Kent State University in the US has published new research claiming that a simple, cheap acid layer over the catalyst in an electrolyzer allows it to split seawater with "nearly 100 per cent efficiency," without any pre-treatment other than filtering.A typical electrolyzer catalyst, says the team, might be made from cobalt oxide, with chromium oxide on its surface. Seawater would generally ruin these catalysts…

RMIT researchers say they've unlocked cheaper, more energy-efficient green hydrogen production with a new electrolysis technique boosted by sound waves. With these high-frequency vibrations active, standard electrolysis produces 14x more hydrogen.Where batteries can't carry enough energy, or take too long to charge, green hydrogen is rising as an important zero-emissions fuel that carries a higher density of electrons and supports fast refueling. Green hydrogen is created through electrolysis; splitting water molecules…
