New technology is offering an economic approach to large scale energy storage. An electro thermal energy storage (ETES) breakthrough does more than address bulk power storage though.
By coupling electricity, heat and cooling ETES represents an opportunity to break the energy system from reliance on fossil fuels.
There's a compelling need to increase utility-scale energy storage capacity in response to the dramatic growth in intermittent renewable generating capacity like wind and solar. Although current technologies such as chemical batteries are rapidly improving, to date bulk power storage has been dominated by pumped storage hydropower.
