Summary

This chapter reviews the transformation of renewable electricity via electrolysis to gas that is subsequently stored or fed into gas grids as hydrogen or methane after methanation. The different technologies for transforming the electric power into gas are outlined. Emphasis is put on the methanation step including the generation of CO2. The capacity and limitations of the natural gas grid to absorb hydrogen are discussed, and also the options for geological storage. The use of hydrogen in transportation and reconversion to power are compared from the economic point of view.
