Energy generated from the sun, wind and other renewable sources naturally varies – when the supply dips, there’s less electricity available to power and heat our homes. Being able to store it is ...

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an ...

Researchers have uncovered a way to improve the efficiency of a type of grid-scale storage crucial for a global transition toward renewable energy. Research by the Oregon State University College of ...

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 world's transition to a net-zero future requires vast amounts of long-duration energy storage, a need that current lithium-ion batteries cannot fully meet because they can only store energy for a ...
