VRB® Energy’s MW-Class VRB-ESS® are custom engineered to pair with solar or wind farms, replace peaker plants and help large mines and C&I customers meet 100% renewable energy targets.
Suitable for pairing with solar and wind generation as power plants of the future, projects like 10MW 100MWh systems are custom engineered in large-footprint configurations utilizing our containerized 1MW Power Modules and large-sized external tanks.
From California to Texas to New York, and 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 10 hours) storage to deliver firm power on demand, and when it is needed most.
Unlike other battery formats, VRB-ESS are utility-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) can use 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® MW-Class systems are robust systems specially engineered to deliver 1, 10 or 100 MW of power for 4 to 10 hours to meet the needs of large-scale solar and wind farms, serve data center and mine applications, and to replace utility peak power plants.
VRB-ESS® deliver a variety of ancillary services and peak power management. Systems can respond to grid conditions within 100ms, 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.
VRB-ESS® MW-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
• Provide a variety of ancillary services including fast frequency response over 100% of hours (as opposed to peaker plants that are only operated about 5% of hours)
100% depth of discharge with no degradation yields low LCOE.
The electrolyte can be fully recycled at end of project lifetime, saving cost and avoiding the expensive disposal costs of other batteries.
Systems are non-flammable and operate at low temperature and low pressure.
Proven performance and robust design yield high availability and low maintenance costs.
Fast dynamic response for transition between charge and discharge or between operating power levels in less than 100ms.
VRB-ESS® have been reviewed and are in compliance with European system quality and safety guidelines.
Each VRB Energy VRB-ESS® 1MW Power Module is composed of 20 cell 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.
VRB-ESS® can be discharged each and every day to full depth of discharge without any capacity degradation, delivering greater operational flexibility and lifetime than lithium-ion batteries.
While lithium-based batteries are well suited to consumer electronics and electric vehicles, their 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.
VRB Energy currently has over 500MWh of projects under development, with increasing interest being shown for storage projects of 8-hours duration.
VRB Energy has the most proven vanadium battery technology with extensive track record of reliable performance.
Storage duration can be increased from 4 to 8 or even 12 hours at a low incremental cost providing project owners with ultimate flexibility.
