Building Innovative Green Hydrogen systems in an Isolated Territory: a pilot for Europe

BIG HIT will create a replicable hydrogen territory in Orkney (Scotland) by implementing a fully integrated model of hydrogen production, storage, transportation and utilisation for heat, power and mobility. BIG HIT will absorb curtailed energy from two wind turbines and tidal turbines on the islands of Eday and Shapinsay, and use 1.5MW of PEM electrolysis to convert it into ~50 t pa of hydrogen. This will be used to heat two local schools, and transported by sea to Kirkwall in 5 hydrogen trailers, where it will be used to fuel a 75kW fuel cell (which will provide heat and power to the harbour buildings, a marina and 3 ferries when docked), and a refuelling station for a fleet of 10 fuel cell vehicles. The project employs a novel structure to manage the hydrogen trading, and dissemination that includes a follower territory and associations of over 1640 isolated territories.
