A 2023 Pacific Energy Forum report revealed Niue’s pilot project achieved 78% round-trip efficiency – beating many lithium-ion systems in island conditions. Their secret sauce? Using seawater’s natural pressure at 40m depth to boost output. Talk about working smarter, not harder!
[pdf] The Botswana energy storage project is quietly becoming Africa’s dark horse in the clean energy race. As of March 2025, this $120 million initiative has already deployed enough battery capacity to power 15,000 homes during peak demand.
[pdf] For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NREL researchers study and quantify the unique economic and grid benefits reaped by distributed and utility-scale systems.
