China Just Flipped the Switch on the World’s Tallest “Water‑Battery” Dam — A 182.3‑Meter Pumped‑Storage Giant in Jiangsu

China’s newest grid “shock absorber,” explained China has switched on a 1.35‑gigawatt pumped‑storage hydropower station in Jurong, Jiangsu—a province that anchors the Yangtze River Delta’s heavy industry and surging power demand. Built by State Grid’s pumped‑storage arm (State Grid Xinyuan), the station

Forget Dams: Startup Raises $8M to Turn the Deep Ocean Into a Gigawatt‑Scale “Gravity Battery”

In‑depth report A fresh (salty) take on a century‑old workhorse Sizable Energy’s pitch is simple: keep the proven physics of pumped hydro, but move it offshore to escape the land, water and topography constraints that dog onshore megaprojects. The company uses two

Energy Storage: The Secret Weapon of the Clean Energy Revolution

Energy storage captures energy for later use, making intermittently-produced power (like solar or wind) available on demand enelgreenpower.com, energy.gov. – Major storage types include electrical (batteries, capacitors), mechanical (pumped hydro, flywheels), thermal (molten salt, ice) and chemical (hydrogen, fuels) energy.gov, eia.gov. –
