Hydrogen coming from renewable electricity is identified by energy policies as promising strategy due to its greening effect on power generation and its use as driver of a renewable fuel economy. The decrease in renewable electricity production costs as well as the balancing and power stability issues induced by the dramatic expansion of renewable energy installations drive the market and the policy to account for hydrogen as a solution. In this chapter, an overview of the Research & Development projects funded by the European Union in the field of solar hydrogen is presented.

Geographical Islands have been considered a challenge environment to test renewable energy integration strategies as well as cutting-edge technologies due to the alternation between actual grid-connected and island mode. This is due to the weak connection to the mainland and, subsequently, the Power Grid as well as the strong changes in seasonal energy demand leading to congestion and stability issues.
