Long-Duration Energy Storage intelligence — updated daily.
The 10 MW / 40 MWh national demonstration all-vanadium flow battery project in Chengde's Shuangluan district has completed hoisting, piping, cabling and electrolyte filling and is now in fine-tuning and grid-connection test preparation.
Bondada Engineering has secured an EPC contract from GIPCL for a 20 MW / 120 MWh vanadium redox flow battery in Gujarat, billed as India's largest grid-scale VRFB installation, with a 10-year O&M scope and an 18-month delivery window.
India's target of roughly 236 GWh of battery storage by 2030 is meeting its first utility-scale flow battery award, as state-linked utilities such as GIPCL and NTPC turn to vanadium redox flow technology for long-duration capacity.
AEMO data shows batteries taking 5.8 GW of 7.5 GW in new NEM connection applications, while Modo Energy forecasts 24.4 GW of four-hour-plus battery capacity by 2030 as the pipeline shifts towards longer durations.
Beijing Puneng's VRB Pod product line is being applied across grid-scale, industrial hybrid, distributed and off-grid projects, from a 50 MW/200 MWh Hubei installation to a copper mine in Arizona.
Invinity Energy Systems has raised GBP 25 million, including a GBP 12.2 million cornerstone investment from the UK's National Wealth Fund, to cut product costs and expand vanadium flow battery manufacturing in the UK and US.
Bondada Engineering has received a Letter of Intent from GIPCL to build a 20 MW/120 MWh vanadium redox flow battery at a gas plant complex in Vadodara, Gujarat — described as India's largest grid-scale VRFB system — with an 18-month delivery schedule and 10-year O&M.
Inlyte Energy and CutPeak Energy will deploy up to 80 MWh of iron-sodium long-duration storage at Berkshire East Mountain Resort, one of two demonstrations funded under Massachusetts' $40.3 million AMP grant program.
The world's largest vanadium flow battery came online in Dalian, China in December, pairing 175 MW of power with 700 MWh of storage and marking the largest single deployment of flow battery technology to date.
Flow batteries store energy in liquid electrolytes held in external tanks, run for up to 12 hours and are currently the cheapest option for storage beyond eight hours — a growing niche as grids shift to renewables.
Just one of 21 eligible projects using Invinity's vanadium flow batteries entered Ofgem's provisional first-round LDES portfolio, prompting the company to warn it could reconsider further investment in British battery manufacturing.
Invinity Energy Systems is seeking at least £20 million, including a conditional £10 million commitment from the UK National Wealth Fund, to fund product development, working capital and manufacturing through early 2028.
