Integration of Renewable Energy Sources and Hydrogen Storage in Porto Santo

With respect to energy production, most of the islands in Europe and in the other parts of the World depend on importation, mainly from oil and its related products. Islands are trying to increase the penetration of renewables and some of them have as target to become 100% renewable energy based - island, satisfying their energy demand 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, but also for transport. This paper describes one model for optimising the integration of hydrogen usage with intermittent renewable energy sources. The model is applied to the island of Porto Santo, Madeira, Portugal. Dimensioning the components of such a system, including renewable energy intermittent source, electrolyser, hydrogen storage and a fuel cell, that can be successfully integrated in the island power system, and help securing the supply, is not an easy task. Since the intermittence of a renewable source has a different pattern from the intermittence of the load, and when both are of the same order of magnitude, it is very hard to use the statistic approach with load duration and Weibull curves. It is necessary to model the system on hour per hour basis, during a representative year. For energy planning it would be necessary to build a model over the planning horizon, usually 20-30 years. The H2RES model was developed to simulate the integration of renewable sources and hydrogen into island energy systems. The use of the model will demonstrate the problems of increasing the penetration of renewable energy source in islands. The H2RES model was applied to the power system of Porto Santo island, Madeira, Portugal, in two test cases, peak shaving and 100% renewable. A model for optimisation and energy planning of integration of hydrogen storage and renewable energy sources has been devised for small and medium power systems (1-100 MW). The model includes a wind and solar PV modules, while others can be straightforwardly added. The model was tested on the data for Porto Santo island, for two different cases, peak shaving and 100% renewable power system. For each of the test cases two scenaria were optimised, one with only wind as a renewable source, and the other with a wind-solar mix. The results have shown that in case of peak shaving wind-solar mix might be more effective, but that for the case of 100% renewable wind system be certainly more cost effective.
