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.
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.
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.
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.

Reference case provided for positioning only. Actual economics depend on load profile, tariff structure, operating strategy and final system specification.
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.
Conductive Polymer Frame
A mouldable component aimed at integrating structural, electrical and sealing functions in a simplified cell architecture, reducing part count and opening a more scalable manufacturing route.
High-Power Ministack Module
A standardised module concept intended to raise power output per unit and reduce the number of stack modules required at system level, simplifying both manufacturing and field maintenance.
Modular Stack Architecture
A repeatable architecture enabling improved scalability, easier maintenance and better electrical and hydraulic organisation across the full system platform.
Integrated System Platform
Cell, stack, hydraulics and system layout are developed as one coordinated platform, with the aim of avoiding bespoke engineering on every installation.
Target performance direction
Lower installed cost
Target installed system cost of 297 €/kWh at 6 hours, using the current design-stage assumptions.
Higher output per unit
Target operating point of 600 mA/cm², with reduced stack count at the same power output.
Industrial asset horizon
Long service life and stable cycling are central to the intended value proposition for industrial users.

Structured engagement for industrial partners, EPCs and technical stakeholders
IonVe is currently focused in disciplined validation and partner engagement around site screening, technical review and pilot preparation.
Site-Specific Screening
IonVe can review interval load data and electricity contract structure to assess whether a long-duration system is relevant for a specific industrial site, and where the economic drivers actually come from.
Request a screening discussionAccess to Technical Progress
As milestones are reached, IonVe can share selected technical information with serious counterparties, including test direction, validation logic and development-stage data packages.
Discuss technical reviewCo-Development Pilot
Following proof-of-concept validation, IonVe intends to work with a limited number of partners on pilot projects that generate real operating data and accelerate industrial learning.
