The growing proportion of renewable energies in worldwide power generation is playing a key role in the reduction of global CO2 emissions. However, this development poses huge challenges to power grids, which will have to become much more flexible in the future in order to accommodate these fluctuating energy sources. Technologies such as electrolysis that Siemens is developing, can help to meet this challenge.
Electrolysis uses electrical energy to split water into oxygen and hydrogen, which can serve as a storage medium, energy carrier, CO2-neutral fuel or feedstock for many industrial applications. As a result, hydrogen is driving the decarbonization process and paving the way for a new age — one of affordable renewable electricity.
