Revenues from flexibility provided to the power system

In addition to selling hydrogen, electrolysers can gain revenues by providing various grid services (e.g. offering reserves, peak shaving, capacity firming or alleviating grid congestion). Although these services are unlikely to provide the main revenue stream, when added to the revenues from providing hydrogen, their revenues can significantly improve the economics of electrolyser operation.

Electrolysers can provide valuable grid services and help keep the power grid stable by ramping production up and down depending on its needs. The additional revenue from these services would then drive down the final price of green hydrogen, helping to accelerate the development of the green hydrogen economy.
