Treball desenvolupat dins el marc del programa 'European Project Semester'.

Today it is often diesel generators which provide the energy supply for remote islands in the archipelago. This project is about the development of a model for evaluation of energy needs but also to find a concept for replacing old generators by sustainable energy solution. The evaluation model was used to calculate the heat and electricity needs of two specific islands. The project included also the task to find a way to store excess energy. After comparing methods of storing energy, hydrogen fuel cells were found to have important advantages. They can store large amount of energy, are relatively cheap and are environmentally friendly. Solar and wind energy have been chosen as the main power sources. Sun and wind are widely known and available in the archipelago and obtaining energy out of these sources is known technology. The rare thing is the storage by hydrogen fuel cells. Storage by hydrogen fuel cells consists of four main stages: namely production, storage, utilization and reutilization. This research shows that it is technically possible to use wind and solar power as main energy sources as well as storing energy in hydrogen fuel cells to create an autonomous off-grid power supply all year round.
