Praia, Sept. 6, 2024 (Lusa) — Cabo Verde's first pumped storage hydroelectric power station will start operating by 2028. Its power output is equivalent to more than a quarter of the largest (fuel-fired) power station on the island of Santiago. [pdf]
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]
Fast-forward to 2025: Muscat’s Nama Power recently deployed a scaled-up version, pairing 50MW solar farm with Tesla’s Megapack storage. Result? 18% reduction in diesel generator use during night shifts at Port Sultan Qaboos. [pdf]
The world's first 300-megawatt compressed air energy storage (CAES) demonstration project, "Nengchu-1," has achieved full capacity grid connection and begun generating power in Yingcheng, Central China's Hubei Province, a milestone for China's energy storage technologies. [pdf]
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.

Swiss company Climeworks has announced the start of operations of Mammoth, the world’s largest direct air capture and storage (DAC+S) facility to date, in Iceland. Like its predecessor, Mammoth is powered by the Hellisheidi geothermal power plant of ON Power. [pdf]
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywhe. In FESSs, electric energy is transformed into kinetic energy and stored by rotating a flywheel at high speeds. An FESS operates in three distinct modes: charging, discharging, and holding. Charging mode: During this phase, the flywheel rotor absorbs external energy and stores it as kinetic energy. [pdf]
PSH functions as an energy storage technology through the pumping (charging) and generating (discharging) modes of operation. A PSH facility consists of an upper reservoir and a lower reservoir, which are connected by water conveyances (e.g., penstocks, tunnels). [pdf]
These plants will use pumped storage hydropower technology, with a total estimated capacity of 2,472 MW. The first facility is expected to begin operation by 2034. The project with the fastest progress is at the Chulabhorn Dam in Chaiyaphum Province, where EGAT has already started a feasibility study. [pdf]
