The Battolyser: a battery that also produces hydrogen challenges conventional hydrogen production technology

Hengelo, The Netherlands, 26 January 2021

Delft University of Technology (TU Delft) spin-off Battolyser is preparing to install a large-scale battery-based energy storage system that will also produce hydrogen. The patented technology will challenge the dominance of conventional alkaline electrolysers in hydrogen and ammonia production and help make the transition to clean energy possible.

The Battolyser solution was designed to do three things well. One; capture and store surplus renewable energy, which is generated when there is a lot of sun and wind. Two; produce hydrogen once the battery is fully charged. Three; use the electricity stored in the battery to continue producing hydrogen or return this electricity to the grid when there is a shortage of solar and wind power.

“Conventional electrolysers can do this too, as can conventional batteries, but the patented Battolyser technology does it better and at lower costs in situations where it really matters,” said its inventor, Fokko Mulder, Professor at the Chemical Engineering department of Delft…
