Neptune Energy and RWE agreed to jointly develop H2opZee—an offshore green hydrogen project—ahead of 2030.
H2opZee is a demonstration project which aims to build 300-500 megawatts (Mw) electrolyzer capacity in the North Sea to produce green hydrogen using offshore wind. The hydrogen will then be transported to land through an existing pipeline with 10-12 Gw capacity.
A feasibility study is expected to begin in second-quarter 2022. The project is an initiative of TKI Wind op Zee, an initiative supported by the Dutch government.
Future energy supply, decarbonization
H2opZee consists of two phases. The first includes the feasibility study and setup of an accessible knowledge platform, Neptune said in a Feb. 15 release. The objective is to start roll-out of hydrogen at sea in the Netherlands. Implementation is expected to occur in the second phase. A tender methodology is not yet defined.
Green hydrogen can play a role in future energy supply, and the energy transition can be “faster, cheaper and cleaner if we integrate existing gas infrastructure into new systems,” said Lex de Groot, managing director, Neptune Energy.
The company will apply lessons learned from PosHYdon—the world's first offshore hydrogen pilot on a working platform—to H2opZee, he said (OGJ Online, July 22, 2021).
“The faster we can scale up green hydrogen at sea, the faster industries such as chemicals and steel production can become more sustainable,” he said.
