VRB-ESS® MW-Class
Based on a 250kW or 500kW containerized building block, in 4, 6 and 8 hour configurations, systems are scaled from 1MWh to 200MWh.
Slider

VRB® Energy’s MW-Class VRB-ESS® can be combined with almost any volume of electrolyte.

Suitable for deployment at utility substations, as peaker plant replacements and on solar or wind farms, as well as at commercial and industrial sites or in microgrids.

VRB-ESS® MW-Class systems are based on 250KW and 500kW containerized modules. They are typically 1MW / 4MWh up to 10MW / 80MWh in size suitable for deployment at utility substations, commercial and industrial sites, and in support of solar or wind farms, and microgrids.

Each VRB-ESS® MW-Class system can be combined with almost any volume of electrolyte according to the requirements of a particular application. Typical configurations use four, six or eight hours of storage depending on the amount of energy required.

VRB-ESS® MW-Class Power Modules have a nominal rating of 250kW AC, and have charge and discharge characteristics optimized for providing the maximum output power per unit cost.

VRB-ESS® MW-Class benefits:
• Low cost, Safe, Scalable
• 100% Capacity, Long Life

On the utility side, VRB-ESS® deliver a variety of ancillary services and peak power management. Systems can respond to grid conditions within ½ cycle, providing frequency and voltage support in real time, while simultaneously reserving energy for peak power management and ramp rate control. VRB-ESS® enable utilities and renewable energy developers to deliver energy (particularly solar and wind energy) when it is most valuable, and make more efficient use of existing infrastructure.

On the customer side, “behind-the-meter” at C&I facilities, VRB-ESS® reduce operating expenses through multiple benefit streams:
• Reduction of peak demand charges from utilities.
• Integration and optimization of on-site renewable energy.
• Provision of backup power that reduces losses in the event of utility outages.
• Reduction of wear on equipment through improvement of power quality.

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® 250kW 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.
