Rotterdam Port to house Battolyser plant for green hydrogen production

By Toby Sterling

AMSTERDAM (Reuters) – The Port of Rotterdam on Monday said it will help develop a 14,000 square metre factory for Battolyser Systems, a company that designs combined battery and green hydrogen production machines.

Financial terms were not disclosed.

The port, which has announced a series of hydrogen-related deals this year, said it views the company, a spin-off from the Delft University of Technology, as an anchor for a part of the port that will be devoted to companies helping to get carbon out of supply chains.

“Companies in the port are already actively working on projects regarding production, imports, shipping, storage and use of green hydrogen,” port CEO Allard Castelein said in a statement. “With this factory we add green hydrogen equipment manufacturing to that portfolio.”

Battolyser, which has funding from entrepreneur Kees Koolen, is seeking to commercialise systems based on iron nickel batteries, which produce hydrogen by electrolysis — using electricity to “split” water — once fully charged.

The idea is that during the day, when electricity from wind and solar power is cheap and abundant, the battery will charge and convert power to hydrogen. And at night the system switches off and the battery may feed electricity back into the grid.

“So when there is an imbalance in power markets and prices shoot up, we can help balance that, so we can make money whilst balancing the grid,” CEO Mattijs Slee said in an interview.

Battolysers are also the first locally made electrolysers, he said. With many Dutch companies seeking to replace with hydrogen, demand for electrolysers is expected to rise.

“Even though we are sort of the epicentre of hydrogen in Europe, we do not have a electrolyser manufacturing facility, or capacity at all in the Netherlands,” he said.
