To all those who think that solar thermal power or in fact any renewable power employing natural flows will still have limited 24/7 base power output- there are a number of storage options already in existence. A star performer in these is the disassociation of ammonia closed loop system. This enables power to be produced 24/7 even in the wintertime from a summer sun without any power loss from storage at ambient temperatures! Correct scaling with input, load and time enables this as with any storage system. And there is an explosion of promising technologies being developed. It’s worth keeping in mind that the mount of the sun’s energy falling on Australia in one day is equal to all the world’s requirements for 6 months 24/7. And wind, tidal and wave are equally of large scale and can be stored actually surprisingly cheaply.
