Surrounded by the sea off the coast in MidNorway, there is an island called Myken. This small island has about ten permanent residents, and for more than 50 years has been supplied with electricity via a 32kilometre undersea cable (电缆). A break that appeared in the cable last autumn resulted in two months without power, so the island community started looking into a better way of sourcing their electricity.
“Myken is far out at sea, so as far as possible it should be taking care of things itself,” says Trude Tokle, who is the project manager of Myken's energy project. “This is why we want Myken to become entirely selfsufficient in energy. It is also important to take the environment into consideration,” she says.
Many point to the idea that the solution may lie in a hydrogen (氢) plant, specifically tailored for small islands. The “raw materials” for hydrogen production come from nature itself in the form of the sun and wind, Researchers have calculated that energy costs will be lower by using hydrogen production than the undersea cable option. And it is possible to store energy in the form of hydrogen for longer periods. This means that supplies will not have to rely on a lot of expensive batteries or external energy sources, even during periods when the sun isn't shining, or the wind isn't blowing.
The Myken project has attracted several technology companies. They are currently working on a pilot project. The project involves experiments on the feasibility (可行性) of the hydrogen system in which electricity is generated from solar and wind sources. The electricity can be used immediately, but during periods when all the energy generated is not required, the spare energy can be used to split seawater into hydrogen and oxygen. The hydrogen can be stored in a tank, and used later to generate electricity. The pilot project will help researchers know more about how effectively the system will work in the hydrogen plant. Since the island has a distillery (酿酒厂), where the distillation (蒸馏) process relies on energy, a hydrogen plant on Myken offers an even greater environmental benefit. Spare heat from the hydrogen system can also be used for the heating part in the distillation process.
“In Norway alone there are about 300 islands inhabited all year round by small populations,” says Kyrre Sundseth, a hydrogen researcher in Norway. “All of these islands may be candidates for using this technology. In global terms we're talking about 10, 000 similar islands.”
