In late November, in a quiet corner of Devon, England, workers began adding a secret, light brown powder to water as they mixed up a special fluid that can store energy. They blended it with the ...

Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, ...

The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according ...

China has been aggressively expanding its pumped hydro storage capacity in recent years, positioning these power plants as crucial "stabilizers" for its evolving electricity grid as the nation ...

In 2023, around 84 per cent of new global electricity generation capacity was from solar and wind power. The increasing affordability of solar, combined with the rapidly growing population, energy ...

Southeast Asia's pumped hydro capacity is projected to grow from 2.3 GW to 18 GW by 2033. Major investments are planned in the Philippines, Vietnam, Indonesia, and Thailand, driven by state-owned ...

Looking over the edge of a Columbia River Gorge slope, you can see the river more than 2,000 feet below. A former aluminum smelter sits to the left at the bottom of the cliff. Wind turbines spin ...
