Sustainability consultancy ERM has launched offshore trials in South Wales to test its Dolphyn Hydrogen process at Pembroke Port. The process combines electrolysis, desalination, and hydrogen production on a floating offshore wind platform. It involves proton exchange membrane (PEM) electrolyser technology and produces green hydrogen for power generation, transport, industrial purposes, and heating. The trials aim to test various aspects of the hydrogen production process under floating conditions, including monitoring desalination and electrolyser equipment behavior. ERM's digital twin tool, emissions.AI, is being used to accelerate learning and development for the project. The trials are significant as they are the UK's first offshore hydrogen production trials and have received funding from the UK Government's Department for Energy Security and Net Zero. ERM aims to deploy full-scale production units at multiple locations if the trials are successful, marking a crucial milestone in scaling low-carbon hydrogen production.
