World’s highest-efficiency hydrogen system scales up for mass production

Posted on by

Hysata claims its capillary-feed electrolyzer is the world's most efficient, using some 20% less energy to produce hydrogen while also being cheaper to install and maintain

You have to throw some energy away to make hydrogen – typically around 20-30%, even with the best systems, which use around 52.5 kWh of energy to create a kilogram of hydrogen that can store 39.4 kWh of energy. It’s a waste of renewable energy, and it contributes to the high cost of a green fuel option that’s really struggling to compete against fossils and batteries in many applications.

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 allo… Continue reading Acid coating converts regular electrolyzers to split seawater→

Clever device efficiently splits hydrogen and lithium out of seawater

Posted on by

One problem with renewably-produced hydrogen is that it uses fresh water – and with a quarter of the world’s population already facing severe water scarcity at least one month of every year, freshwater is an ever more finite and precious resource. So t… Continue reading Clever device efficiently splits hydrogen and lithium out of seawater→

High-frequency sound waves make electrolyzers produce 14x more hydrogen

Posted on by

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.Conti… Continue reading High-frequency sound waves make electrolyzers produce 14x more hydrogen→

World’s first direct air electrolyzer makes hydrogen from humidity

Posted on by

Australian researchers have developed and tested a way to electrolyze hydrogen straight out of the air, anywhere on Earth, without requiring any other fresh water source. The Direct Air Electrolyzer (DAE) absorbs and converts atmospheric moisture – eve… Continue reading World’s first direct air electrolyzer makes hydrogen from humidity→
