Defense and Energy 


High power density energy storage is large, heavy, or expensive leading to problems in the defense in energy industry. The CSC is a fundamental technology that can integrate into a wide variety of systems and industries. Through feedback from ~110 interviews, we focused our efforts to advanced warfare technology for the military as well as power factor correction for individual buildings and utilities. Both require high power density energy storage which are either large, heavy, or expensive due to the lack of advanced energy storage technologies. For the defense industry, large/heavy technologies limits the agility/mobility of the user and if it is expensive it is limited to elite military groups only. In the energy industry, large technologies leads to a limitation of physical space (a waste of real estate), and if it is expensive the technology may not be adopted due to long return periods. We propose the CSC technology as a way to reduce the size, weight, and the cost of high power density storage. A single military division (~60,000 soldiers) uses about 2 million pounds of batteries each year for 57,000 soldiers which equates to about 1,419 cubic feet of batteries. Using the CSC as an advanced textile in soldier’s uniforms will reduce these numbers by 570,000 pounds (29%) and 354 cubic feet (25%). In terms of power factor correction, an average 3MW commercial grid with a power factor of 0.8 actually requires 3.75MVA to operate. Using the CSC in utility transmission lines and to distribute power in IT equipment for businesses, will improve this city’s power factor by ~5%, which requires only 3.53MVA to operate reducing the apparent power by 0.22MVA and saving ~$800 per day in this example (assuming $0.15/KWhr).
