Decarbonization of the electric power sector is essential for sustainable development. Low-carbon generation technologies, such as solar and wind energy, can replace the CO2-emitting energy sources (. Kobe Steel's CAES technology comprises storing compressed air in a tank with a screw-type compressor first; and subsequently expanding the stored compressed air with a screw-type expander to drive a power generator that is directly connected to the expander and thus to generate electricity, wherein the heat generated by the compression is collected by a heat medium for preheating the compressed air before it flows into the expander, thereby improving charge/discharge efficiency.

Barbados Light & Power Company's technical assessments have revealed that the currently approved 15 MW of battery energy storage systems (BESS) possesses the capability to maintain grid stability only up to a maximum of 99.9 MW of total installed distributed photovoltaic (DPV) systems. 12 As of August 1, 2024, the cumulative capacity of DPV systems connected to the grid was nearing this threshold, reaching almost 100 MW. 12 This near-capacity situation has a direct and immediate consequence: no additional renewable energy customers can be connected to the grid until further BESS capacity is brought online. 12 This bottleneck in grid connectivity poses a significant impediment to the continued expansion of renewable energy generation within Barbados, potentially affecting homeowners and businesses eager to adopt cleaner energy solutions. 14 [pdf]
