|The Utsira Project|
Hydro and its partner Enercon have decided to extend their combined wind power and hydrogen facility on Utsira until spring 2008. The demonstration project on the island Utsira off the coast of western Norway started operating in summer 2004 and was originally scheduled to run two years.
Two wind turbines at the combined wind and hydrogen plant on Utsira produce power for 10 households. Surplus electricity is stored in the form of hydrogen produced via electrolysis. When the wind doesn’t blow, a hydrogen motor and fuel cell convert the stored hydrogen back into electricity.
The partners have decided that there is still much valuable experience to gain, together with the need to test new components and solutions for use on future facilities. Among other plans are testing of new internally designed electrolyzer technology at the facility.
The Utsira project has provided us lots of valuable experience in an area that the entire world is interested in and where Hydro is at the forefront of development. We now want to make some adjustments and try out new technological solutions to optimize the facility.—Ulf Hafseld, business development manager, Hydro New Energy
