Generation integrated medium duration energy storage

From the earliest days of electricity systems, there has always been heavy reliance on energy storage. Energy was stored in a compact and dense form close to the point where it could be turned into electricity. Usually, that energy was in the form of hydrocarbon fuels that release CO2 when burned. With decarbonisation, we are turning to renewables for capturing primary energy and it is not obvious to most people that the opportunity to store energy prior to generating electricity still exists. It does. Moreover, some of the storage technologies best suited to the multi-hour (medium-duration) timescales that are most relevant for integrating renewables are also particularly compatible with integration. This webinar lifts the lid on a set of technical possibilities that could have very strong economic importance for countries and continents navigating towards the enviable “100% renewables” status.
