Hydrogen from Renewable Energy as Energy Carrier in Island Energy Supply

The primary energy supply of most of the islands depends on imports of oil and its related products and sometimes electricity through weak electricity grid connections with mainland. Some islands are trying to become renewable islands, satisfying their energy demand mainly or entirely from indigenous and renewable sources. Since most available renewable energy sources are intermittent, energy storage has to be devised. The most promising technology is storing hydrogen, which can later be used for electricity production, and also for transport. This paper describes application of the H2RES model for optimisation of integration of hydrogen usage with intermittent renewable energy sources to the power and transport system of the island of Porto Santo, Madeira, Portugal. It shows that it is possible to significantly increase the penetration of renewable energy sources, albeit at a high cost. The H2RES model, which includes hydrogen storage, reversible hydro and batteries as storage technologies, wind, solar PV, hydro and Diesel as electricity sources, can serve as a valuable tool for island energy planning for satisfying power, water and hydrogen for transport demand.
