Thermal Energy Storage AND Batteries – “It’s not a question of one or the other, it’s which one is the right application now for my campus.”

With increased intermittent renewable power generation, there comes a need for grid scale energy storage to manage the supply and demand for electricity. Utility rates throughout the U.S. are becoming more sensitive to the time of use, and owners are concerned with the rising costs of energy.

Battery storage and Thermal Energy Storage (TES) are two types of grid scale energy storage systems that can be utilized to store energy (during the low cost of electricity) and deploy that stored energy to reduce the peak electric demand. But knowing which energy storage technology to implement first may be challenging.

Attendees will learn about some of the pros and cons of both battery and TES systems and begin to formulate their own strategy on which energy storage technology may be best for their campus. During this presentation, a case study of two example TES systems will be reviewed.

Guy Frankenfield, is responsible for the energy related projects at DN Tanks, specializing in Thermal Energy Storage (TES) tanks. Guy’s career has included working for Fortune 500 companies, including Trane, IBM, and Honeywell. His 42 years of business experience includes mechanical engineering design and energy efficiency project development. He is an active member of ASHRAE’s technical committee 6.9 Thermal Storage including past chairperson. Guy has presented at numerous National conferences including: AEE (World, East, and West), International District Energy Association (IDEA), ASHRAE, APPA, the Energy Exchange, Energy Storage Association, EUEC, and EUCI.
