Transition to renewable hydrogen

Industrial hydrogen

Water electrolysis is the one discussed negative balancing energy for the electricity grid and for direct connection to renewable electricity production units as it serves not only power to power but offers a far wider product portfolio. Options for power to gas, power to fuel, power to heat and power to chemicals are available using this technology route. Direct use of hydrogen is expected to revolutionize our transport sector, with cars, buses and trucks powered by hydrogen.

Today four percent of the world’s hydrogen consumption already originates from electrolysis plants , mainly chlor-alkali installations. Dramatic changes are expected in the future as the need to avoid carbon dioxide emissions increases. Alongside renewable hydrogen production via water electrolysis, the move towards carbon dioxide as a feedstock will change the way chemicals are produced today.

In the chemical industry hydrogen plays a major role in the production of fertilizers such as ammonia and urea and is used as a desulfurization agent in oil refineries. It is also needed for all syngas routes to e.g. methanol and thus to gasoline.
