Renewables-powered high temperature heat pumps are cheapest option for industrial steam
New research from Austria has compared different industrial heat-generating techniques and has found that wind or solar-powered heat pumps are the cheapest and most environment-friendly solution.
Kuwait tenders 1.1 GW solar project
Kuwait has tendered a 1.1 GW solar project to supply electricity to the Ministry of Electricity, Water, and Renewable Energy under a 30-year power purchase agreement (PPA).
Energy trade model for interconnected renewable microgrids
Scientists from China proposed a new method for energy trade optimization between interconnected microgrids and the main utility grid. The novel approach utilizes particle swarm optimization and gravitational search algorithms with Nash Bargaining.
US battery storage demand to surge within this decade, says SEIA
US demand for battery energy storage systems will grow sixfold by 2030, according to a recent report by the Solar Energy Industries Association (SEIA), but only with serious investment, coordination with experienced manufacturers, and collaboration with allies.
Solar-assisted heat pump for biomass drying
Scientists from Finland have built an experimental system that allows the drying of woody biomass with solar thermal energy and a heat pump. They claim PV may play a complementary role in the proposed setup.
Asantys Systems offers containerized solar-storage solutions in Sierra Leone
Asantys Systems has developed containerized solar-storage solutions in Sierra Leone, featuring solar containers with capacities ranging from 30 kW to 130 kW. The containers include inverters from German manufacturer SMA and batteries from Hoppecke Batterien.
GDI unveils 100% silicon anode for rapid charging, higher energy density
Third-party tests of GDI’s 100% silicon anodes show that they offer more than 30% energy density than graphite anodes, allowing for 15-minute rapid charging up to 80% state of charge (SOC) for hundreds of times back to back.
PV-driven liquid air storage system for buildings
An international research group has developed a PV-driven liquid air energy storage (LAES) system for building applications. Simulations suggest that it could meet 89.72% of power demand, 51.96% of heating demand, and 11% of cooling demand in a PV-powered building.
Charging quantum batteries
Researchers in Japan have taken advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the performance of so-called “quantum batteries.” They believe these advances could help to bring the technology a little closer to reality.
