Proven Energy Storage Systems Designed for Today’s Renewable Energy Storage Needs

Posted: 15 August 2019

Severn Drives & Energy are working with a leading global technology developer to introduce to the market a cost-effective vanadium flow battery storage solution, being 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 some of 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.

Our grid-scale energy storage systems provide flexible, long-duration energy with proven high performance. Systems start at 250kW / 1MWh and can be as large as 100MW / 800MWh in size, installed at utility, commercial and industrial sites, in support of solar or wind farms or in isolated microgrids.

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.

UTILIZED CAPACITY 100% DISCHARGE CYCLE TO FULL DEPTH-OF-DISCHARGE

Vanadium flow 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

Vanadium flow batteries 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 COST OF OWNERSHIP 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).

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

Unlike other battery systems, vanadium flow batteries are a robust product, contains no heavy metals like lead, nickel, zinc or cadmium and the liquid electrolyte in our products is non-toxic, non-flammable and is 100% reusable.
