Modular approach “could help” hydrogen market grow
Connecting modular electrolyser units helps plants scale quickly and deals with the intermittency of renewable generation
A modular approach to hydrogen electrolyser technology could help the sector scale rapidly, according to the developers of a green hydrogen project in Denmark. The GreenHyScale project will demonstrate 100MW of green hydrogen based on a modular alkaline electrolyser platform delivered by Green Hydrogen Systems. A 6MW module was demonstrated as the first step in the project, which is now operating at 24MW, and will eventually lead to an electrolysis plant of at least 100MW size. “Scaling is the key word—we are scaling a market and you cannot scale up in one jump,” says Niels-Arne Baden CEO of Green Energy Systems, speaking on a webinar. “We believe in a modular approach not huge custom-built
