Civil air defense energy storage system

What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

Does the Department of Defense need a new approach to electrical grid infrastructure?

T he Department of Defense (DOD) needs a new approach to electrical grid infrastructure to maintain security and access to operational energy. Recent natural disasters and cyber attacks have exposed the vulnerability of the current system, posing threats to military operational readiness.

Can a diesel power system meet DoD's electric energy resilience requirements?

Such a system can: Meet DoD’s electric energy resilience requirements with a higher reliability than typically found in diesel-fueled systems. Provide resiliency without use of diesel fuel, thus eliminating the risk and vulnerability associated with the diesel fuel supply chain during a long-duration grid outage.

What are the components of a thermal energy storage system?

The major components—the compressor, expander, heat exchangers, thermal energy storage medium, and storage containers—experience cycles of temperature and pressure. The combination of pressure and temperature causes fatigue and cycling processes accelerate their failure and replacement.

What is energy storage or duration?

Energy storage or duration is scalable and affordable. Because energy storage capacity or duration is solely dependent on the volume of carbon blocks, it can easily be increased without significant costs. This allows the BESS to have durations of multiple days at an affordable price. The BESS is inherently safe.
