This layout purifies water first and then uses a conventional alkaline electrolyser.

This research grants no UK approval and states no installed price. A coastal scheme would still need a lawful seawater intake and a lawful way to return or treat concentrated brine, plus landward consents for pipes, compounds and buildings. Regulators differ between England, Scotland, Wales and Northern Ireland, and exact thresholds depend on site and scale. The project would also need a grid or private-wire connection, hydrogen handling and a buyer for the gas.
