Parc Fermé Energy delivers long-duration, non-degrading energy storage systems designed for critical infrastructure, industry, and national energy resilience.
From grid-scale deployments to mission-critical facilities, we engineer Vanadium Redox Flow Battery (VRFB) solutions that operate reliably for decades — without compromise.
Parc Fermé Energy designs, deploys, and supports long-duration energy storage (LDES) systems built for reliability, safety, and scale — across infrastructure-grade applications.
Vanadium Redox Flow Batteries are fundamentally different from conventional lithium-based storage.
They are purpose-built for long-duration, high-cycle applications where reliability matters more than hype.
A flow-based energy storage system engineered for decades of operation.
Unlike conventional batteries, VRFB systems separate energy storage from power generation.
Energy capacity is defined by electrolyte volume, while power is determined by the stack — allowing independent scaling, unlimited cycling, and zero capacity degradation over time.
This architecture enables true long-duration energy storage designed for infrastructure-grade reliability, not consumer electronics.
Energy is stored in liquid vanadium electrolyte inside external tanks.
Ion exchange occurs inside the stack — converting flow into electricity.
Electricity is delivered to the grid or load with no degradation.
Electricity is delivered to the grid or load with no degradation.
Why flow batteries scale differently
Energy & Power Decoupled
VRFB systems store energy in liquid electrolyte while power is defined by the stack — allowing independent scaling without redesign.
No Capacity Degradation
Unlike lithium systems, VRFB capacity does not fade with cycling — delivering predictable performance over decades.
Built for Long Duation
Flow batteries are engineered for grid-scale, multi-hour storage where safety, longevity, and uptime matter most.
Parc Fermé Energy solutions directly support national and global sustainability targets, including UAE Net Zero 2050 and Vision 2030 energy diversification.
By enabling renewable energy to be stored and dispatched reliably, VRFB systems reduce reliance on fossil-fuel peaking plants, eliminate short-lived battery waste, and support long-term carbon reduction at infrastructure scale.
Designed to align with national energy strategies, utility-scale decarbonization, and long-term grid resilience mandates.
This is long-term sustainability — not short-term offsetting.
