Gravity storage would be a cheap though limited method, salt liquification and sand banks (sand heated to 500C) already in use. Many of our reservoirs plus London barrage may be useful for hydro or in the case of lakes like Vyrnwy pumped storage and many could also be fitted with floating solar and floating wind turbines, the former to reduce evaporation
