The role of power-to-gas in the European Union

The primary energy panorama in the European Union is still dominated by a significant share of fossil fuels in the form of coal,natural gas and oil.As a result,an ecological transition is encouraged in order to curb the related CO_(2)emissions from fossil fuels thus providing an alignment with the Paris Agreement.In the light of a renewable dominated future in the EU,Power-to-Gas technologies can play a major role not only to curb the current CO_(2)emissions but add extra flexibility to the power network.Great challenges remain ahead,due to the difficulties to couple all the elements needed in such a complex value chain,from technical to financial.
