Partnership to develop floating green ammonia production facility

Supported by Norway-based BW Offshore and Dutch Oceans Capital, Rotterdam-based SwitcH2 is developing industrial-scale offshore green hydrogen and green ammonia production units based on FPSO (floating production, storage, and offloading) technologies.

Supported by grant funding from the Dutch Government’s GroenvermogenNL TSE (Top Sector Energie) scheme, SwitcH2 aims to launch a new open-sea project in northern Portugal utilising CorPower Ocean’s wave energy technology, plus wind and solar. CorPower Ocean’s wave energy converters turn wave motion into rotation, which is converted into electricity by generators inside a buoy.

SwitcH2 said its NH3-FPSO unit will use a vessel nearly the size of a VLCC (Very Large Crude Carrier), to support a 300MW electrolysis plant on deck. The produced green ammonia will be temporarily stored in pressurised tanks in the vessel and then exported to shore via shuttle carriers. The floating facility is expected to reach an annual production capacity of almost 300kton of green ammonia when operational from 2029.
