Current Situation Energy storage is not a new requirement, but the scale of energy storage required with the increased penetration of renewables in the generation mix has changed - 100 s of MWh in any given hour. There are different ways of tackling problem of utility-scale energy storage. How to choose? Demonstration projects 25

Today, ancillary services consume generating capacity. When loads provide these reserves, generating capacity is freed up to do what it was designed for, i.e., generate electricity. Electrolyzer technology can offer grid stabilization services as a fast-acting load while simultaneously storing surplus power. 34

To conclude Large scale Alkaline and PEM are entering a phase where engineering and manufacturing will become as important as technical leadership. Focus should be on cost reduction, engineering scale-up, and market development. Hydrogenics is developing a MW PEM and alkaline stack and system building block will offer a major step toward affordable large-scale renewable hydrogen. Government-Industry investment is required to demonstrate cost and efficiency of demonstration plants.
