Abstract: Decarbonizing the electric grid is essential for climate change mitigation and it requires a shift from fossil fuel-powered generation technologies to renewable energy technologies. The intermittency of renewables means that they can only be reliably integrated into the grid when complemented with long-duration energy storage technologies. An emerging storage technology, termed Thermal Energy Grid Storage (TEGS), has been shown to have low enough energy and power capacity costs such that it can enable a cost-effective decarbonization of the grid. The design optimization of this TEGS system for its integration into the electric grid is explored here.
