Maritime Hydrogen Highway Work Package 3

Offshore hydrogen generation

A major innovative aspect of offshore generation of green hydrogen is the design of modular offshore generation platforms. Three main units – production, storage, and bunkering – are designed as add-ons, which can be easily upscaled and fitted to various offshore wind projects and platform types.

Two case studies are designed to look at the most likely variations in platform design. The first is a retrofit of the required modules to an existing, bottom fixed oil & gas platform in close proximity to existing offshore wind farms with relatively close distance to shore. The second, a new design of a floating platform that can be used on a wider range of wind farms, located further from shore in deeper waters to accommodate the developments of the UKs floating offshore wind industry in the decades to 2050. Both designs will be evaluated against the alternative of transporting electricity to shore or connecting large offshore structures to the national grid by means of existing or new pipeline networks.

Provide an assessment of the hydrogen generation capabilities for a range of offshore wind farm locations and develop a concept design for modular generation, storage and offloading units for integration into standard offshore platform design. Separate case studies are conducted for retrofitting existing Oil & Gas platform and developments of novel floating offshore wind platforms, assessing the various options for hydrogen storage and transport and provide recommendations on the ideal combinations for key operational scenarios. Larger infrastructure characteristics around the UK will be included in the judgement such as existing structures, pipeline networks and readiness of ports and industrial areas to accommodate large amounts of energy generated offshore.
