STORING HEAT FOR POWER

Thermal Energy Storage; Thermal Storage for HVAC in Commercial Buildings, District Cooling and Heating, Utility and Grid Support Applications, and High-Temperature Storage at CSP Facilities

“Thermal energy storage (TES) is an often unrecognized but important component of the developing market for energy storage systems…[TES is presently most] often used to provide cooling capacity for commercial buildings…

“…TES systems are also increasingly seen as an effective means of shifting electricity use from daytime peak periods into less expensive periods of the day or at night, saving money and increasing overall system efficiency…Newer forms of TES, including molten salt storage, may be used with concentrated solar power generation facilities to store energy collected in daylight hours for later use.”

“Pike Research’s analysis finds that the annual U.S. market for incremental TES capacity totals $268 million, with 246 megawatts (MW) of new capacity installed in 2011 in five market segments: packaged air conditioning, chiller TES systems, district energy, residential heat TES, and commercial heat TES…

“The report forecasts that the TES market will expand at a compound annual growth rate of 13.5% through 2020, resulting in an $850 million annual domestic market and cumulative TES capacity of 4,500 MW. Globally, TES is expected to grow substantially through 2020, with worldwide revenues of $3.6 billion and added capacity of 3,824 MW in that year…”
