Thermal Energy Storage for Grid Resilience

Date: October 18, 2024; Time: 2:30 PM Location: PWEB 175

Abstract: The energy sector is undergoing a major transformation.  More renewable energy resources are being added to the energy grid to replace aging fossil fuel power plants and meet growing demand.  However, these renewable energy resources are more intermittent and rely on favorable weather conditions to produce energy often resulting in a misalignment of energy generation and demand.  Thermal energy storage (TES) is a powerful tool to combat this misalignment.  This talk will discuss how TES can improve the resilience of the evolving energy grid.  Near-ambient temperature TES can complement building technologies to reduce building energy usage for heating and cooling, shift energy usage from on-peak to off-peak times, and extend the capabilities of existing building heating and cooling systems.  At elevated temperatures, TES can serve as a peaking resource delivering power to the grid by discharging high grade heat to a thermal power cycle when renewable generation drops or demand rises.  As the energy grid continues to evolve, TES provides unique opportunities to further enable widespread renewable energy deployment.
