VRB® Energy is a global leader in vanadium redox battery (VRB®) technology-driven to empower a clean energy future for the world.

Today the world is faced with the twin challenges of global warming and air pollution; this destructive combination is damaging and costly in terms of both human health and the environment.

The good news is that new solar and wind power installations are now recognized as the lowest cost of generation in most parts of the world, and our long-duration, deep-discharge, long-life batteries are the best way to integrate these variable renewable energy sources onto the grid.

Unlike other batteries, our systems are safe, reliable, and recyclable.

VRB® Energy, formerly known as Pu Neng, is a private company, majority-owned by Ivanhoe Electric, a US corporation specialized in mining resource exploration and related technologies. Ivanhoe Electric is privately owned by I-Pulse, a global leader in developing innovative commercial applications for pulsed power technologies.

PROVEN ENERGY STORAGE SYSTEMS

Grid-Scale Energy Storage Systems

Our grid-scale energy storage systems provide flexible, long-duration energy with proven high performance. Systems start at 500kW / 2MWh and can be 100MW and larger, typically of 4 to 8 hours duration, installed at utility, commercial and industrial sites, and in support of solar or wind farms.

Microgrid Energy Storage Systems

Our long-duration systems are ideally suited to stabilize isolated microgrids, integrating solar and wind power in a safe, reliable, low maintenance, and environmentally friendly manner.
 
 

WHY VRB® ENERGY?

CAPACITY
100%
DEPTH-OF-DISCHARGE,
NO CYCLE LIMIT

Vanadium redox batteries can be discharged over an almost unlimited number of charge and discharge cycles without wearing out. This is an important factor when matching the daily demands of utility-scale solar and wind power generation.

LONG LIFE
25,000+
PRODUCT LIFE CYCLES
AT FULL POWER

VRB® Energy products have a proven life of at least 25 years without degradation in the battery. Annual maintenance is low, and the vanadium electrolyte, which is 40-60% of battery cost, retains its value at end-of life.
 

ECONOMICS
2-3x
LOWER LCOE THAN
LITHIUM BATTERIES

Lithium-based batteries have inherently shorter lifetimes and are not well suited for longer duration storage (4+ hours). Vanadium outperforms lithium on depth-of-discharge (DoD), cycle life, and end of life value (lithium carries a disposal cost).

PROVEN

With over 1,000,000 hours of operation on systems in our research and development labs and in the field, VRB® Energy has the most proven technology and reliable energy storage products in the industry today.

SAFETY

Unlike other battery systems, VRB® Energy’s robust products contain no heavy metals like lead, nickel, zinc or cadmium. The liquid electrolyte in our products is non-toxic, non-flammable and is 100% reusable.

RECYCLABLE

At the end of 25 or more years, our electrolyte can be reused in another battery or recycled for reuse for use as commodity vanadium. This is dramatically different than other battery types that ultimately bear a waste disposal cost.

SCALABLE

VRB Energy's products are available with customized power ratings that range from 500 kilowatts to over 100 megawatts, and scalable energy capacity from four to eight hours or more by expanding the amount of electrolyte.
