Renewables face challenges such as intermittency, curtailment due to overcapacity or difficulties with long transmission distances. Vattenfall sees hydrogen as having great potential to address these challenges. The surplus of renewable energy from wind and solar can be used to produce hydrogen via electrolysis instead of leaving it unexploited due to limitations of the grid or low demand. In addition, in order to electrify all sectors and to compensate for the phase out of conventional power there will be huge demand for renewable electricity. So-called green hydrogen, as produced from renewable sources, can act as a buffer between energy demand and supply or as an energy carrier between the electricity sector and the heat or transport sector, which are otherwise difficult fully to decarbonise by electrical means.
