A Superior and Distinctive
Given its performance characteristics and benefits relative to other commercially available storage technologies, A-CAES is particularly well-suited to address the growing need for long-duration energy storage on the grid. Importantly, A-CAES has a unique advantage in its ability to simultaneously provide long storage durations while being flexibly sited where the grid requires it.
Ability to Site
Proprietary purpose-built air caverns allow for flexible project siting
No toxic material, contaminants, or thermal impacts on environment; suitable for urban settings
System design optimized to match client requirements, with independent settings for charge, discharge and storage capacity
Long-duration of storage enables wide-scale provision of grid capacity
Synchronous motors and generators provide rotational inertia in support of electrical grid stability
Full suite of ancillary services available including voltage support, spinning reserve, black start and frequency response
Lowest installed cost per kWh for large-scale, long-duration energy storage (100+ MW)
50+ year system life, with no replacements required and nearly unlimited cycling
Low operating costs, and increased efficiency over traditional CAES systems
