The project CurtHyl in the Port of Rotterdam aims to make use of the renewable electricity from Vattenfall’s existing onshore windfarm Slufterdam, which would be partly curtailed due to a grid bottleneck, to produce 100% renewable hydrogen via electrolysis. This hydrogen is to be distributed via an existing hydrogen pipeline owned and operated by Air Liquide. In the next phase, starting operation from 2025, the production shall be increased to a 100 MW electrolyser or more with electricity supply possibly from windfarm Hollandse Kust Zuid.
