Switzerland to host world’s largest redox flow storage project
Flexbase plans to build a 500 MW redox flow storage project in Laufenburg in early 2025.
Dual-source CO2 heat pump based on photovoltaic-thermal evaporators
Researchers in Italy have conceived a dual-source heat pump system that uses both a finned-coil evaporator and a solar evaporator made with three photovoltaic-thermal panels. Thanks to the combined action of the two evaporators, the heat pump can achieve higher evaporation pressure and coeffficient of performance.
JSW Energy, Reliance Power win SECI’s new 1 GW/2 GWh storage tender
JSW Neo Energy and Reliance Power have secured 500 MW each in Solar Energy Corp. of India’s (SECI) latest tender to set up 1 GW/2 GWh of standalone battery energy storage projects.
Greece announces downsized auction for battery storage in coal regions
The Greek government decided to auction 100 MW less capacity than initially sought and to offer more money to the awarded projects than expected.
Firebrick thermal energy storage could reach 170 GW in the U.S. by 2050
Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.
The Hydrogen Stream: Equatic making anodes to produce H2 from seawater
Equatic says it has started annual production of 4,000 anodes for hydrogen generation from seawater in Singapore and Canada, while Nuvera Fuel Cells says it will demonstrate its first operational hydrogen-powered AC generator set and DC fast charger.
IEA calls for stronger solar, wind integration measures
The International Energy Agency’s (IEA) latest report warns that failing to support integration at the point of deployment could jeopardize up to 15% of solar and wind projects by 2030. This shortfall would reduce their combined share of the global electricity mix by 5%.
Grant launches air source heat pump for residential applications
The novel propane heat pump has a coefficient of performance of up to 4.9 and can reportedly achieve a flow temperature of up to 55 C.
Fronius debuts hybrid residential solar inverter
Designed for U.S. solar installations, the GEN24 Plus inverter enables users to connect their solar array to home energy storage.
Researchers develop lithium-sulfur battery that can be cut, folded
By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.
