This chapter examines the use of pumped hydro techniques in configurations other than well-established pumped hydroelectric storage (PHES). Most are of similar scale, aiming to bring high-power, high-energy storage to regions where PHES is not feasible. The largest geological piston-in-cylinder systems can also address emerging markets that require energy levels beyond the capability of PHES. Future networks, relying more heavily on variable renewables, may require 100 h or more of gigawatt-class storage capacity to harvest large energy surpluses and to ride through prolonged periods of low power generation.
