Increasing the supply of renewable energy sources in island energy systems

With respect to energy production, most of the islands depend on importation, mainly from oil and its related products, while other islands rely on usually weak electricity grid connection to the mainland. In some cases, there is no way to link the islands to continental European energy networks, making difficult the implementation of the solutions to reduce environmental costs, while at the same time increasing the security of supply to the level necessary to maintain the quality of life and competitiveness of island economies. Due to high energy costs the islands are proving to be excellent test beds for introduction of new technologies, and some islands are trying to become so called renewable islands, to satisfy their energy demand mainly or entirely from indigenous and renewable sources, thus increasing the security of supply, and employment opportunities, without necessarily increasing the costs. Islands that have energy sources like hydro or geothermal can easily integrate them into the power system, but those with mainly intermittent renewable energy sources are confronted with the necessity of energy storage. The most promising technologies are reversible hydro, where geography allows, and storing hydrogen where it does not. Also, in order to increase the efficiencies of the supply systems of electricity, water and transport fuel, these could be analysed in an integrated approach. This paper describes the H2RES model for optimisation of integration of hydrogen usage with intermittent renewable energy sources on the example of an isolated island in Madeira archipelago, Porto Santo. It shows that it is possible to significantly increase the penetration of renewable energy sources, albeit at a relatively high cost, with hydrogen storage technology.
