Titanium emerges as a vanadium alternative for redox flow batteries
A Japanese-Chinese team developed a titanium molten salt redox-flow battery using abundant titanium ions and molten salt electrolytes to enable high-voltage, fast, and stable grid-scale energy storage. The system demonstrates high efficiency of over 97%, strong cycling stability, and improved cost and scalability compared to vanadium-based batteries, with further optimization underway.
Spain completes testing of Europe’s largest research vanadium BESS
Spain’s Fundación Ciudad de la EnergÃa (Ciuden), a government energy research foundation, has completed operational testing of a 1 MW/8 MWh vanadium redox flow battery (VRFB) system at its Cubillos del Sil technology center, which it says is the largest vanadium flow battery in Europe dedicated to applied research.
