01

Long-duration storage is economically viable for industry today

Industrial sites with high demand charges and time-of-use contracts can already generate a positive business case for 4–12 hour storage. The barrier is not economics; it is the absence of an affordable, reliable product.

02

Lithium-ion is not cost-effective beyond 4–6 hours

At durations of 6 hours or more, the total cost of ownership of Li-ion over a 20–30 year industrial lifetime becomes significantly higher, mainly due to pack replacements.

03

Existing RFB systems remain too expensive

Current products remain constrained by high component count, machined graphite parts and custom engineering. Standardised, catalogue-style industrial products are still missing.

Where IonVe fits

Built for industrial sites that cycle frequently and plan for the long term

IonVe is positioned for the part of the market where long lifetime, safety, and 4–12 hour duration matter. The target use case is not every storage project. It is the segment where industrial users need daily cycling, predictable maintenance and a 20–30 year asset horizon.

  • Peak shaving and electricity cost reduction at energy-intensive sites
  • PV self-consumption and energy shifting in behind-the-meter applications
  • Long-duration storage where Li-ion becomes less attractive on a full-life basis

IonVe is designed for storage durations above 4 hours. For shorter durations, Li-ion often remains the more appropriate choice.

Architecture

Cell-to-system design aimed at cost, efficiency and manufacturability

IonVe's approach is to engineer the actual Redox Flow Battery architecture. The goal is to redesign the cell and stack platform so that redox-flow systems become more practical for industrial deployment: fewer units, simpler assembly, improved hydraulic control and a more repeatable product platform.

The render shown here represents the current design direction of the module and system platform.
