Hundreds of local households will become the first in the world to use zero carbon hydrogen for heating and cooking during a five-year trial. An aerial view of the site at Fife Energy Park. If successful, up to 1,000 people will be able to sign up to the network in its initial stage. And it could eventually expand to homes and businesses across the UK. Known as the H100 Fife Hydrogen Demonstration Project, the £18 million scheme will be based at Fife Energy Park in Methil, and powered by the giant Ore Catapult wind turbine.
