According to current scientific knowledge the emission of greenhouse gases is the source for anthropogenic climate change. In line with its strategy for sustainable growth, the European Union has put in place a series of energy policies strongly promoting the long-term reduction of greenhouse gas emissions. Moreover, a major challenge in the EU energy sector continues to be security of supply and strong dependence on fossil fuel imports from foreign countries. It is well known that the EU imports over 60% of its gas and 80% of all the oil, this situation affects strongly all sectors, but in particular the transport sector. To reduce the impact of CO2 emissions on climate and improve the socioeconomic conditions of its Member States, renewable Energy policy is central on the EU political agenda, particularly over the last decade during which time ambitious targets for renewable energy production and consumption have been set up to 2020 and 2050. Hydrogen is expected to play a key role in a transition towards a low-carbon economy, especially within the transport sector, the energy sector and the (petro) chemical industry sector.
