Hydrogen production through electrolysis was well underway in early 2021 in Orkney where clean energy sources (wind, waves, tides) were producing excess electricity that could be used to create hydrogen which could be stored until needed. In November 2019, a spokesperson for the European Marine Energy Centre (EMEC) made this comment: "We’re now looking towards the development of a hydrogen economy in Orkney". In late 2020, a plan was made to test the world’s first hydrogen-fueled ferry here. One report suggested that, "if all goes well, hydrogen ferries could be sailing between Orkney’s islands within six months".
