Indian flow battery startup Delectrik Systems has been awarded a 20MW/120MWh vanadium redox flow battery (VRFB) project in Gujarat, an eight-hour long-duration system, according to a report published on 28 October 2026.
Eight-hour duration is the headline
20MW of power paired with 120MWh of energy: an eight-hour duration asset, the configuration reported for the Gujarat award.
The sizing places the project squarely in long-duration energy storage (LDES) territory rather than the one-to-four-hour band that dominates lithium-ion procurement. For flow technology, duration is the commercial argument: energy capacity scales with electrolyte volume and tank size, while power scales with stack area, so longer durations tend to favour vanadium systems on cost per megawatt-hour.
Part of a shift from demonstrations to commercial supply
The award fits a broader transition described in recent electrolyte market research: the VRFB electrolyte business is moving from supplying demonstration projects to large-scale commercial supply, driven by global power system demand for long-duration storage. Growth is expected to come not only from new project construction but also from capacity expansion, maintenance of existing electrolyte, concentration upgrades, recycling and reuse, and long-term supply contracts.
A startup among established electrolyte names
Delectrik Systems Pvt Ltd appears in YHResearch's list of leading VRFB electrolyte players alongside Dalian Rongke Power, Hunan Yinfeng New Energy, Pangang Group Vanadium Titanium & Resources, HBIS, Beijing Xingchen Xinneng, Sichuan Weili De Energy, U.S. Vanadium, Storion Energy, VanadiumCorp, Australian Vanadium, Vecco Group, Bushveld Electrolyte Company, LE System, Oxkem, AMG Titanium, Hong Jing Metal Corporation and others.
Why VRFB suits grid-scale duty
Compared with short-duration lithium-ion storage, vanadium flow batteries offer intrinsic safety, long cycle life, independently designable capacity and power, and stable deep charge/discharge performance. Those characteristics suit grid-side peak shaving, renewable output smoothing, industrial park storage and large microgrids, the applications that dominate the downstream buyer base for electrolyte.
What the market will watch
The announcement excerpt did not disclose contract value, the offtaker, delivery schedule or electrolyte sourcing arrangements. Those details matter because competition in the segment is shifting from pure product supply toward resource security, cost control, formulation technology, quality consistency and project delivery capability.
Vanadium price volatility remains the key variable: it feeds directly into electrolyte manufacturing cost and therefore into VRFB economics versus lithium-ion, sodium-ion and iron-based flow alternatives. With V2O5 quoted near 98,000 yuan/tonne in China in early November, the raw-material backdrop for a contract of this size is currently range-bound rather than falling.
