Bolivia Advanced Compressed Air Energy Storage Project

What is advanced compressed air energy storage (a-CAES)?

Hydrostor has a patented Advanced Compressed Air Energy Storage (or A-CAES) technology that delivers clean energy on demand, even when solar and wind power are unavailable. A-CAES can provide energy for 8-24+ hours, helping to balance supply and demand on the grid, with an operational lifespan of 50+ years with no efficiency degradation.

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.

How does a compressed air power plant store off-peak energy?

Conventional compressed air energy storage (CAES) power plants store off-peak energy by compressing air into underground caverns. During periods of peak demand for energy the compressed air can then be released from underground, then heated and used to drive turbines as it expands.

What are the heating demands in Bolivia?

Residential heating demands in Bolivia are quite low, though they do notably increase throughout the transition as access to energy services increase, except for biomass for cooking, which is phased out by the end of the transition. Heating demands are projected to increase from 52 TWh in 2015 to 205 TWh in 2050. Fig. 12.

Can compressed air energy storage improve the profitability of existing power plants?

Linden Svd, Patel M. New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants.

Will Electric based heating drive the transition in Bolivia?

Heating demand in Bolivia transitions from a system dominated by natural gas and biomass to a largely electrified heating sector. Because of the low cost of renewable electricity, electric based heating will drive the transition for Bolivia’s heat sector. Fig. 13.
