Energy storage has long been regarded as something close to a holy grail. Of course, there are ways of storing some forms of energy – using pumped water or compressed air for instance. There are conventional batteries – and there have been advances in their capacity over the last few years. But the search for storage systems which are simultaneously economic and practical for use at scale in the modern energy market has long been a source of frustration.
Recent advances made by scientists in the US suggest, however, that real progress is now being made and that major breakthroughs are close. The whole of the energy sector should be watching because any such breakthrough could transform the economics of the whole industry. Read more
