Project Description:
§ Proposes to research the feasibility of using 3% by volume of anti-freeze filled copper tubing in the storage tanks of a CAES (tank) system to assure that the temperature swing and pressure swing are acceptable as inputs to the effective operation of a turboexpander.
Proposed Outcomes:
§ A scaled prototype will be fabricated and tested.
Anticipated Benefits:
§ The system has the potential to provide cost effective energy storage for wind farm applications as well as possible industry applications.
§ Compared to batteries, the proposed system offers the potential of greater energy storage capacity and longer life (20 years compared to 5 years for batteries). Also, there would be no need to purchase, maintain, and dispose of toxic and corrosive chemicals.
§ When incorporated into a wind farm operation the cost of power from the CAES is projected at $.07/kWh which is competitive.
