Long-Duration Energy Storage intelligence — updated daily.
Anhui has proposed tying capacity payments for grid-side independent energy storage to discharge duration, using a 165 yuan/kW-year baseline and a duration-divided-by-six-hours formula that could improve revenue for 4–6 hour flow storage projects.
China’s 15th Five-Year Plan for a new energy system sets a 300 GW new energy storage target for 2030 and identifies long-duration storage, sodium-ion batteries and flow batteries as priority technology pathways.
Wien Energie has commissioned its first redox-flow battery pilot at the Donaustadt power plant site in Vienna, using an 80 kW/230 kWh vanadium system to store surplus solar power and assess the technology's role in its future storage mix.
Energy Dome commissioned a Piacenza manufacturing plant for CO2 storage core equipment on 8 October 2026, a week after Antora Energy announced a 5.8GWh multi-day thermal storage project using 2,400°C carbon blocks in Pratt, Kansas.
A UK government fund led a £25 million equity raise for Invinity Energy Systems, while Australian Vanadium advanced an electrolyte leasing model, reported A$12.4 million in cash and continued bidding for the Kalgoorlie VBESS project.
A seven-ministry plan for the 15th Five-Year period lists flow batteries alongside lithium and sodium for the first time, while Anhui proposes capacity payments benchmarked at RMB165/kW-year and scaled by discharge duration relative to six hours.
Delectrik Systems won GIPCL's tender to supply a 20MW/120MWh all-vanadium flow battery in Gujarat, while Bondada Engineering received an LOI for EPC plus O&M worth about RMB168 million, or roughly RMB1.40/Wh.
A KAIST team replaced chemical reduction with a catalytic route at an average vanadium oxidation state near +4.1, cutting V3.5+ electrolyte production time by 67% and eliminating residual oxalic acid, with a Pt/C catalyst reused more than 2,500 times.
Antora Energy has begun building a 5.8 GWh multi-day thermal storage system at Pratt Energy's biorefinery in Pratt, Kansas, using 2,400°C carbon blocks to supply industrial heat.
A Dalian Institute of Chemical Physics and Wuhan University team has reformulated tin flow battery chemistry to reach 89% round-trip efficiency, up from 53%, and validated it in a 20-cell, 800 W prototype.
UK vanadium flow battery maker Invinity Energy Systems has closed a £25 million equity financing led by a British government fund, one of the sector's larger single raises this year.
Singapore's Nanyang Technological University and VFT have opened a four-year, S$15 million joint laboratory focused on making vanadium redox flow batteries safer, longer-lasting and cheaper.
