Energy storage is the key to balancing the supply and demand equation. It serves as a method to advance the relationship between energy consumption and production in order to increase efficiency and reduce production costs.
Solar Energy Storage
UC San Diego partners with technology leaders to implement solar energy projects.
- The campus serves as the host site for a Panasonic/ Sanyo 30 kW/30 kWh photovoltaic integrated storage system.
- The California Energy Commission is funding testing of ultracapacitors –devices that charge quickly and store energy from an electric source and discharge it on demand. Maxwell Technologies is testing ultracapacitors with concentrating photovoltaic systems from Soitec (pictured above) to better integrate solar panels with the campus microgrid.
UC San Diego currently has approximately $5 million in California Self Generation Incentive Program and other funding to procure an additional 1.3/2.6 MWH of photovoltaic integrated storage plus 2.5 MW/5 MWH of stand-alone electric energy storage.
2nd Life Batteries
The campus receives Department of Energy/National Renewable Energy Laboratory funding for the endurance testing of 2nd Life electric vehicle batteries in stationary applications. While electric vehicles are charging at campus stations, they can provide electricity to the campus microgrid, if needed, creating a vehicle-to-grid energy storage system.
- BMW Group and UC San Diego are currently deploying a 108 kW/180 kWh 2nd Life battery system that will be integrated with an existing photovoltaic system.
- The California Center for Sustainable Energy and the National Renewable Energy Laboratory are sponsoring the 2nd Life Electric Vehicle Battery Project.
