Water electrolysis is a key technology to realize sector coupling and renewables integration. To establish CO 2 ‐free or ‐reduced value chains as well as carbon capture and utilization, “green hydrogen” is the essential element, serving as fuel, energy carrier, and feedstock for “green chemicals”. As a well‐developed technology, alkaline water electrolysis (AWE) enables industrial scale hydrogen production in high purity. The electrolyzers are highly dynamic in operation and can also serve as primary control reserve, thus further stabilizing the power grid.
