We're keeping a keen eye on stuff like this, things are happening fast, and will have big consequences:
The world's next energy revolution is probably no more than five or ten years away. Cutting-edge research into cheap and clean forms of electricity storage is moving so fast that we may never again need to build 20th Century power plants in this country, let alone a nuclear white elephant such as Hinkley Point. The US Energy Department is funding 75 projects developing electricity storage, mobilizing teams of scientists at Harvard, MIT, Stanford, and the elite Lawrence Livermore and Oak Ridge labs in a bid for what it calls the 'Holy Grail' of energy policy.
Holy Grail of energy policy in sight as battery technology smashes the old order
China has installed 20 gigawatts of new solar power just in the first half of this year. This achievement beats analysts’ expectations by a wide margin. China wants to add 20 GW of new solar every year for the next four, but apparently could do twice that. At the end of 2015, China had about 40 gigawatts of installed solar power, so in just six months it has added half as much again. It already surpasses the previous solar champ, Germany.

The Crescent Dunes “concentrating solar power” plant in Nevada, operated by a Santa Monica firm, is using molten salt as a battery so that it can generate electricity 24/7. It is the first such plant to use solar energy to melt the salt directly instead of via oil, which is a huge advance in efficiency. All electricity plants are just a way to turn turbines using boiling water. If you can turn the turbines with molten salt heated hours ago by the sun, then you can make electricity all day and all night. The Crescent Dunes plant can power 75,000 homes. All those critics of solar power who maintain that it needs gas or nuclear for baseload generation when it is dark or very overcast can now find some other talking point. Solar can do it all. Concentrating solar power costs as little as 10 cents a kilowatt hour, making it competitive with nuclear both in cost and in non-intermittency. Photovoltaic cells plus battery storage may ultimately be cheaper but this means that at the very least we have a relatively inexpensive solar technology that isn’t intermittent.
