The Building Technologies Office (BTO) hosted a workshop, Priorities and Pathways to Widespread Deployment of Thermal Energy Storage in Buildings on May 11–12, 2021. It was focused on the goal of advancing thermal energy storage (TES) solutions for buildings.
Participants included leaders from industry, academia, and government. They discussed the latest developments in low-temperature TES technologies and systems to identify approaches that overcome technology gaps, building integration issues, and market adoption challenges that are preventing the widespread deployment of TES solutions in buildings. Advanced TES technology is a key enabler for achieving a zero-carbon power sector by 2035 and an equitable transition to a decarbonized energy system by 2050. The discussions throughout the workshop helped inform BTO's planned TES technology roadmap and potential future R&D and market-scaling activities related to latent, sensible, and thermochemical TES for buildings.
The workshop was co-hosted by the National Renewable Energy Laboratory, Oak Ridge National Laboratory, and Lawrence Berkeley National Laboratory.
