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.
