Long-duration energy storage project development and commissioning worldwide
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.
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.
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.
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.
