U.S. startup unveils zinc-polyiodid redox flow battery with energy density of 320 Wh/L
BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory.
Peak Energy announces operation of first large-scale sodium ion battery in US
Denver-based Peak Energy claims its sodium-ion battery system offers the lowest operating cost of any energy storage technology on the market today.
French startup offers water heater control to boost PV self-consumption
French startup Ecojoko has introduced a contactor that controls electric water heaters to raise solar self-consumption, with field tests underway since the summer.
Cypriot startup unveils new device to reduce solar curtailment
Cyprus-based Enerthon has developed a smart zero-export control device that prevents PV export losses from curtailment by directing generation to self-consumption. Certification is expected soon.
EcoFlow launches energy management system providing whole-home backup
Global energy company EcoFlow’s latest product, Gateway, is a wall mounted hardware system that can be installed indoors or outdoors and is compatible with third-party inverters and diesel generators as well as EcoFlow’s own extensive product suite.
New model to optimize desert PV plant cleaning schedule
Scientists have used a CPLEX-based MIP model and tested it on a section of the 10 MW Masdar City Solar Photovoltaic Plant. In their simulation, they assume the use of two robotic cleaners to operate over a 90-day horizon. Total cleaning costs were estimated at $7,987.
China Three Gorges commissions world’s largest PV-CSP solar plant
Hybrid project pairs a 100 MW linear Fresnel concentrated solar power (CSP) with a 900 MW PV facility, delivering 24-hour output and demonstrating large-scale storage integration.
Europe’s largest sodium-ion battery installation goes live
Switzerland’s Phenogy has launched a megawatt-hour-scale sodium ion energy storage system at a commercial site near Bremen Airport in northern Germany. With this project, the Swiss manufacturer is making its debut on the European energy storage scene, backed by ambitions to develop fully vertically integrated local manufacturing.
Renewables overbuilding, proactive curtailment can reduce Europe’s energy system costs
New research from the Netherlands showed that renewables and short-term storage can meet around 92.5% of Europe’s electricity demand in future energy scenarios, with the remaining 7.5% being satisfied by green hydrogen. The scientists considered Europe as fully self-sufficient with zero import-export of power or hydrogen, with each of the 37 countries included in the modeling having a self-sufficiency rate of at least 80%.
Enhancing dual-axis solar tracker performance with new optimization techniques
Researchers in India have developed two solar tracker optimization techniques can purportedly increase power generation by up to 54.36% when combined. One uses a light sensor and the other relies on data from GPS and a real-time clock.
