Stationary storage is delayed electricity.
Saving the planet and reducing local pollution and costs means mainly solar and wind power for the next 20 years with its sudden shut-downs, extended weaknesses and inability to follow demand even when it is working. Major stationary storage will be demanded in three waves. First is grid support rocketing as countries reach 60% renewables. Secondly will be local grid support particularly when most houses go solar at the tipping point of price and legislation. Both will primarily employ up to six hours' storage to manage demand through the day. Third will come Long Duration Energy Storage LDES for grids. This massive demand will be for over six hours to six months storage due to wind dead for months - as recently happened in the UK- and solar weak in winter. This webinar will help you answer key questions.
Can today's favourites - pumped hydro and lithium-ion batteries - cope? What about their planned variants? Why have redox flow batteries and compressed air recently beaten lithium-ion in several tenders for 4-8 hour storage? Why do we need yet more options? Why will lithium-ion batteries be shunned beyond six hours' storage? With LDES, what are the huge number of options (new batteries and many non-battery options) emerging for up to several weeks' storage and why is there tiny choice for months to seasonal storage with even that useless for microgrids? Although most LDES solutions can also do short term, why will they not be used for that? Will less-intermittent, more-predictable zero-emission sources such as geothermal and tidal power significantly reduce the need for all this storage over the next twenty years?
