Long-Duration Energy Storage intelligence — updated daily.
Rongke Storage is moving into Australia to build a local vanadium flow battery ecosystem, while the 300 MW / 1200 MWh Yongren project in Yunnan nears grid connection and Western Australia advances a 50 MW / 500 MWh flow tender.
NYSERDA has awarded nearly $13 million to 15 projects under its Power Generation and Storage Innovation programme, backing iron-sodium, advanced compressed air and underground vanadium flow technologies.
Wien Energie has commissioned an 80 kW / 230 kWh vanadium redox flow battery at its Donaustadt power plant — Austria's largest operating system of its type and the utility's first water-based electrolyte battery.
SMEGSolar's two-site, 21 MW / 84 MWh storage portfolio carries a total cost of HUF 14.73 billion, of which EU Recovery and Resilience Fund support covers only HUF 2.17 billion at a 14.75% intensity.
SMEGSolar has commissioned a 3 MW / 10.8 MWh vanadium redox flow battery co-located with a solar PV plant in Balatonberény, Hungary — a rare non-lithium project in a market dominated by LFP.
CATL has shipped the first 5.64 MWh EnerQB units to Quinbrook for an Australian 3 GW/24 GWh long-duration storage programme, marking an early GWh-scale batch delivery.
NTU Singapore and spin-off VFT have started a four-year, SGD 15 million research programme on vanadium flow batteries covering stacks, AI monitoring and vanadium recycling.
Eight UK battery operators argue that an oversized first round of a 25-year cap-and-floor revenue guarantee for long-duration storage could raise consumer bills by £1.6 billion.
Anhui's draft capacity mechanism would scale payments by discharge duration, potentially improving revenue for four-to-six-hour flow battery projects.
China's new battery industry plan lists flow batteries alongside lithium-ion and sodium-ion for the first time, signaling a policy shift from demonstration projects to industrial scale-up.
A 2.1 GWh vanadium flow battery project under construction in Europe and Blackridge Research’s 2026 top 10 supplier ranking show flow batteries moving deeper into long-duration storage deployments.
New work from Yongtai Energy, Zhonghe Energy and Chinese researchers targets vanadium electrolyte cost, membrane efficiency and zinc-bromine corrosion, pointing to lower-cost and more durable flow battery systems.
