The first stage of a giant 2.3GW floating wind-fuelled hydrogen complex off Wales could be online within five years, following the signing of a deal between UK-headquartered developer Source Energie and technology outfit ERM Dolphyn.

The pair plan to advance the 300MW Dylan development, sited some 60km off the Pembrokeshire coast in the Celtic Sea, as the lead-off array, with an eye on a “deployment date of 2027/2028”.

“Source Energie is sure that green hydrogen will play a significant role in energy storage, as a fuel for future transportation needs and as a source of hydrogen for industrial processes,” said CEO Kevin Lynch.
