“Natural gas will play a central role in a low-carbon economy: with the advent of power-to-gas and biogas, it will evolve from being a fossil energy to become a green energy. And it presents an indispensable advantage to facilitate the emergence of renewable, but intermittent energy sources such as wind or photovoltaic: it is storable, in already existing infrastructures!”
