Good. Now we are motoring! Power to Gas (P2G) is best for (solar, wind etc.) farm-scale energy storage for most farms where there is no possibility of farm-scale pumped hydro. P2G is excellent for mopping up all the surplus farm power because any energy which P2G can store is an efficiency gain compared to the 100% loss of all curtailed generation. Grid managers should cease paying curtailment payments and spend the same money more wisely offering incentives to farm operators to install farm-scale energy storage. P2G is not as efficient as pumped hydro so the primary grid-scale energy storage will be pumped hydro, reverting to secondary grid P2G when all the hydroelectric reservoirs have been topped up.
