Proc. ASME. ES2023, ASME 2023 17th International Conference on Energy Sustainability, V001T03A003, July 10–12, 2023
Publisher: American Society of Mechanical Engineers
Paper No: ES2023-106662
... electrochemical batteries (e.g., lithium-ion) are uneconomical in this role due to high energy capacity costs. Thermal energy storage (TES) is one promising technology for LDES applications because of its siting flexibility and ease of scaling. Particle-based TES systems use low-cost solid particles that have...
