3 Thermal Energy Storage Thermal storage systems remove heat from or add heat to a storage medium for use at another time like the hot water heater in a home. For ice or water based commercial systems, this means using a chiller to produce ice or chilled water when electric rates are lower or the utility needs load and using the ice for cooling during the peak periods.

4 It s a BATTERY for Commercial Air Conditioning (10-30 kw)

5 Thermal vs. Battery Storage What to remember Electric batteries are great and an important part of the storage solution. They serve many needs since they can deliver electrons. However, Thermal Energy Storage (TES) has significant benefits for commercial air conditioning applications: 1. TES is less expensive 2. TES will not degrade over time, 20+ years life 3. TES will not create disposal issues 4. TES has longer discharge times 5. Tanks are modular and mobile, can be relocated 6. IT DOES WHAT A BATTERY DOES, IT STORES ENERGY. BUT FOR AIR CONDITIONING -YOUR LARGEST ELECTRICAL LOAD 5

11 Drivers for Energy Storage Lower Electric Bills for Owner Reduced Carbon Footprint o Less source energy consumed at power plants at night Water Usage o Air cooled plants with water cooled efficiencies during the day LEED o New buildings based on energy cost Net Zero Design or Zero Net Energy o All forms of energy storage will enable net zero designs Electric Supply Issues o Extra Capacity without additional electrical supply to the site Grid Issues (Utilities) o Many utilities, including HECO, are investigating incentives for storage to manage grid issues resulting from renewable energy additions to the grid 11

12 Old Grid Energy flows mostly one way

13 Modern Grid Energy Flows into and out of the grid

14 The New Shape of the Electrical Grid

15 Net Zero Grid Wind Turbine Solar Panel zero Batteries Fossil Fuels The grid becomes responsible for backup energy when the wind stops blowing or the sun is not shining Fossil fuel is a form of stored energy Thermal Designers tend to remove building sited renewable back up equipment

16 Opportunities Typical applications: o Offices o Education o Military Bases o Government s o Large Retail & Resorts o Hospitals Pacific Palms Hotel, LA
