RheEnergise commissions first ‘high density hydro’ long-duration storage in UK
Pilot long-duration energy storage (LDES) project uses low viscosity, denser-than-water fluid. RheEnergise is panning for future projects in 10 MW to 100 MW range, with six to 20 hours of storage capacity.
India’s THDC commissions new unit of 1 GW pumped storage project
THDC India Ltd., a subsidiary of NTPC Ltd., has commissioned a 250 MW unit of its 1 GW variable-speed pumped storage hydropower project in Uttarakhand.
Unlimited low-cost energy storage
In its latest monthly for pv magazine, the International Solar Energy Society (ISES) explains how pumped-hydro energy storage combined with PV power generation could provide 24/7 power to data centres
Hydrogen can mitigate curtailment in floating PV-pumped hydro energy storage systems
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, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.
Magtel wins €500 million Spain tender for 289 MW pumped hydro with solar
Magtel has secured a tender for a €500 million ($586 million) 289 MW/2,554 MWh pumped hydro project in Spain that will be colocated with 229 MW of solar.
CSP-driven multigeneration system combines hydrogen generation with compressed air, pumped hydro storage
Researchers have designed a novel multigeneration energy system that provides five outputs, namely electricity, hydrogen, cooling, heating, and hot water. The system is mainly powered by a solar heliostat system and incorporates compressed air and pumped hydro storage technologies for storing surplus power.
THDC commissions first 250 MW unit of 1 GW pumped hydro project
THDC India, a subsidiary of NTPC, has commissioned the first unit of 250 MW of a 1 GW variable-speed pumped storage hydropower project in India.
Supercharging pumped-hydro stations with floating PV
Scientists have simulated the addition of floating solar panels to Switzerland’s Etzelwerk, an open-loop pumped-storage hydropower plant. Using 10% of the upper reservoir for the solar panels, the research team was able to add about 20% of the energy output.
Australian state preps up to 20 GWh of battery and pumped hydro capacity
The government of New South Wales (NSW), Australia, is granting grid access to 10 renewable energy and energy storage sites in the new Central West Orana Renewable Energy Zone (REZ), while utility AGL has acquired pumped hydro energy storage (PHES) projects at the Glenbawn and Glennies Creek reservoirs.
Largest ever UK pumped hydro scheme granted consent
Planning permission granted for 1.8 GW/ 40 GWh pumped hydro project in the Scottish Highlands. Developer Gilkes Energy says the real work begins now and is seeking “substantial capital” for the project.
