PROJECT

HOPE Project Innovation Development • Recycled offshore barge: The structure housing the production unit will be a second-hand jack-up barge, demonstrating transformation of infrastructure previously used for oil and gas while also helping to reduce costs and lead times.

• 10 MW PEM electrolyzer: This compact electrolyzer will be the ? rst of its size to be installed offshore.

• Seawater treatment system: This low-energy system which is compact, economical and able to use the heat emitted by the electrolyzer, will be used for the ? rst time to produce green hydrogen from seawater puri? ed by evaporation.

• Underwater ? exible hydrogen pipeline work, transport and installation at sea, and commissioning and start-up of for hydrogen export: The hydrogen will be exported ashore via a ? exible thermoplastic the platform. Activities are due to start immediately and are expected to be composite pipeline of over a km long, which for completed by the end of 2025. As for the Hollandse Kust offshore wind farm, the ? rst time will transport hydrogen produced at sea.
