VRB® Energy’s GW-Class VRB-ESS® are specially engineered to deliver power for 4 to 10+ hours.

Suitable for pairing with solar and wind generation as power plants of the future, 250MW 1GWh systems are custom engineered in large-footprint configurations utilizing super-sized tanks and large-format cell stacks.

From California to China, from Saudi Arabia to South Australia, the rapid transition to low-cost renewable energy will be enabled by pairing it with long-duration (4 to 8 hours) storage to deliver firm power on demand, and when it is needed most.

Unlike other battery formats, VRB Energy systems are industrial-scale equipment well-suited to this task: manufacturing of large-format cell stacks (which determine system power rating) is easily scalable, and electrolyte (which determines the energy rating) is scaled up using large tank farms; both of these elements together result in a much more effective solution than trying to string millions of tiny cells of differing voltages together.

VRB-ESS® GW-Class systems are robust systems specially engineered to deliver 100 MW or 250 MW of power for 4 to 10 hours to meet the needs of large-scale solar and wind farms, and to replace utility peak power plants.

Utilities and grid operators from Australia to Arizona are struggling with integration of large amounts of solar power replacing fossil fuel in wholesale grid supply projects. Solar power is also being adopted at a rapid pace by commercial, industrial and residential users alike. This creates a “duck curve” problem, where utilities have to turn down other forms of generation during the peak solar hours – only to ramp up the power as solar output wanes and evening peak power usage spikes.

This can be addressed with our 4-8 hours of energy storage products, to balance electricity grids and shift valuable solar energy from day to night.

VRB-ESS® GW-Class benefits:
• Pair VRB-ESS® with solar and wind generation to create a power plant solution that delivers firm and reliable power throughout the day
• Lower lifecycle cost of energy LCOE than traditional forms of generation
• Shorter lead time to implement than a new peaker plant
• More than 100% of hours provide a variety of ancillary services (as opposed to peaker plants that are only operated about 5% of hours)

Low LCOE

100% depth of discharge with no degradation yields low LCOE.

Recyclable

The electrolyte can be fully recycled at end of project lifetime, saving cost and avoiding the expensive disposal costs of other batteries.

System Safety

Systems are non-flammable and operate at low temperature and low pressure.

Reliable

Proven performance and robust design yield high availability and low maintenance costs.

Fast Response

Fast dynamic response for transition between charge and discharge or between operating power levels as fast as 50ms.

Quality

VRB-ESS® have been reviewed and are in compliance with European system quality and safety guidelines.

Each VRB Energy VRB-ESS® Power Module is composed of 12 stacks, pumps and controls. Tanks and electrolyte are separate based on desired system energy rating. A power conversion system (PCS) is included for a complete AC system.

VANADIUM vs LITHIUM

Flow batteries store energy in liquid electrolyte, which doesn't degrade.

VRBs boast a longer continuous discharge run time (6-10 hours versus 2-5 hours) than lithium-ion batteries.

While lithium-based batteries are well suited to consumer electronics and electric vehicles, thier lifetimes can be limited.

VRB Energy’s VRB-ESS® technology 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.
