The study, for a 30–50 MW offshore green hydrogen production facility within the Hollandse Kust Noord offshore wind area, follows H2DO securing a 2025 funding award under the Dutch Topsector Energie programme. The consortium includes H2sea, Haskoning, TCI Risk Management, and ECHT Regie in Transitie, with support from Smulders HSM; the work will deliver a FEED entry-ready concept and compare the business case for offshore hydrogen production against onshore electrolysis with HVDC connections, while assessing RFNBO compliance under RED III.
