With Battery Storage only a Partial Solution to the Efficient Use of Wind Power, Germany Plans to Exploit Helgoland as a Hydrogen Distribution Hub
Several European energy companies are currently exploring the feasibility of producing hydrogen out at sea. Although not particularly efficient, electroysis of water to produce hydrogen is a useful way to capture wind energy that might otherwise be in surplus. Batteries could of course be used shorterm energy storage and release, but future projections indicate hydrogen could handle greater quantities of energy over greater timescales and could also be an efficient way to transfer it to the mainland - with one hydrogen pipeline handling the same energy transmission as 5 DC interconnector cables.
