Charging up Stationary Energy Storage

The adoption of variable renewable energy generation based on solar and wind power is rapidly growing. Together, these sources are projected to provide up to 10% of global energy demand by 2023. 1 International Energy AgencyRenewables. https://www.iea.org/renewables2018/ Date: 2018 Google Scholar Wind and solar provide intermittent energy, 2 Sovacool B.K.

To sustain and accelerate this growth of intermittent energy production, electricity systems will require increased flexibility, including the potential to store power over long durations of time. Economical long-term energy storage for stationary applications is a pivotal missing element toward enabling a predominantly renewable energy powered future society
