Sodium-ion battery storage for ultra-low temperatures
U.S. researchers have developed a sodium-ion pouch cell that operates reliably at temperatures as low as –100 C. The battery was tested with simulated and real renewable energy sources, including wind and solar, and maintained stable performance in both laboratory and field conditions.
Where does solar stand in Trump’s ‘all the above’ energy policy?
Wind and electric vehicles have come under the crosshairs for the Trump administration, while solar has been relatively unscathed – so far.
Australian miner energizes 95 MW offgrid wind-solar-storage plant
Australian miner Liontown Resources has flicked the switch on one of the largest off-grid renewable energy hybrid power stations in Australia.
Chinese scientists apply new models for sustainable wind, solar investments in Belt and Road Initiative countries
To assess renewable energy, particularly solar and wind, considering the limited supply of input materials, researchers from Shenzhen University established novel hybrid multi-criteria decision-making (MCDM) models that include a circular economy principles, waste potential and life cycle assessment (LCA).
Bladeless wind energy innovation aims to compete with rooftop solar
A compact, “motionless” wind turbine with a magnetic generator designed for large commercial rooftops provides 5 kW of capacity per unit. Aeromine Technologies secured Series A funding for scaling its innovative design.
EU launches investigation into Chinese wind turbine suppliers
Margrethe Vestager, the executive vice president of the European Commission, said this week that the EU authorities are investigating the deployment of several wind farms in Spain, Greece, France, Romania and Bulgaria.
Portuguese utility says renewables covered 91% of demand in March
Redes Energéticas Nacionais (REN), the grid operator in Portugal, says that renewables covered 91% of national electricity demand in March. This marks the third consecutive month in which clean energy has exceeded 80% of total power demand.
Open-source online tool to optimize wind-solar projects
Scientists in Spain have developed a tool that optimizes the joint production of wind and solar. It combines data, patterns of solar radiation, and wind speeds over time in specific parts of Europe.
French startup reveals rooftop system with PV panels, mini wind turbines
French startup Unéole has developed a rooftop system that combines solar and silent wind turbines. It claims its system can produce 40% more energy than standalone rooftop solar arrays. It is now testing the device, with plans to commercialize it by 2023.
India’s SECI launches 1.2 GW hybrid wind-solar tender
Solar Energy Corp. of India (SECI) said developers have until Dec. 12 to submit bids for 1.2 GW of wind-solar-storage hybrid capacity. The projects will be developed on a build-own-operate basis, anywhere in India.
