Integration of Renewable Energy Sources and Hydrogen Storage in the Azores Archipelago

This paper analyses some technological scenaria to increase of the penetration of RE sources in Corvo and Graciosa islands. The H2RES model, specially developed for this type of work was used to simulate several scenaria integrating RE sources and hydrogen storage or batteries. Based on existing load and meteorological data, several scenaria are developed and fully modelled for those two islands, in order to increase security of supply and reduce pollution. The scenaria modelled were envisaging the following technologies: wind, solar PV, and batteries and hydrogen storage. The present study can be the base for a complete approach of a 100% RES island. The Azores archipelago has been very conscious on environmental concerns and the reduction of pollutants and dependence on imported fuels, mainly by the use of renewable energies. For an appropriate integration scheme, strategies should be developed for a regional high-level energy production with RE systems, taking into account local characteristics. They must specifically reflect the needs and behaviour of consumer daily and seasonal patterns, taking into account the economic development and human needs that have an impact on energy consumption. In Corvo island the main drive for RE integration is security of supply and in Graciosa is fuel dependency.
