Why Redox Flow Batteries Are Special
Updated: Dec 21, 2021
With the effects of climate change happening in real time, the urgency to control greenhouse gas emissions and transition to renewable energy is more pressing than ever. One of the most promising technologies in helping us achieve this goal is the vanadium redox flow battery. What makes redox flow batteries so unique? Why are they up to the task of making renewable energy more accessible to a wider range of businesses and consumers? Here’s what you need to know about vanadium flow batteries and their benefits.
Redox Flow Batteries Offer Sustainable Energy Storage
First and foremost, vanadium redox flow batteries enable homeowners and businesses to use more sustainable solar energy by collecting it when it’s readily available and storing it for nighttime and overcast days. In addition to this, vanadium flow battery technology itself is also more sustainable than lithium batteries, as the electrolyte can be reused. (Learn more: What is a redox flow battery?)
Redox Flow Batteries Are Safer
Vanadium flow batteries are superior to lithium batteries from a safety standpoint. The water-based electrolyte is non-explosive and non-flammable, making these redox flow batteries a safer alternative to lithium, which is especially important when a battery is used to store energy for residential purposes.
Redox Flow Batteries Have Better Discharge Capacity and Longer Lifespan
Vanadium flow redox batteries don’t lose capacity or decay over time like other types of batteries, so they always discharge fully at 100 percent capacity no matter their age. In contrast, other types of batteries lose capacity as they get older, so it’s often necessary to oversize during installation in anticipation of this. With a redox flow battery, matching daily demands with storage capacity is straightforward.
Vanadium redox flow batteries also have a longer lifespan than lithium batteries, typically lasting 25 years or more without changes in performance, even near the end of their lifespan.
Redox Flow Batteries Are Cost-Effective
Transitioning to renewable energy has a number of barriers related to cost, but vanadium redox flow batteries are an option that is cost-effective thanks to their extended lifespan and discharge capacity. In fact, redox flow batteries have the lowest cost/cycle on the market today. Because vanadium electrolyte retains its end-of-life value, vanadium batteries have lower disposal costs.
Redox Flow Batteries Are Low Maintenance
StorEn vanadium redox flow batteries offer simplified maintenance, making these batteries more practical for widespread use. No routine maintenance visits are necessary; instead, a built-in Battery Management System sends an alert when maintenance is required.
Redox Flow Batteries Are Versatile
Vanadium flow batteries can be used in a number of different settings and environments. They can withstand outdoor and indoor use at a range of different temperatures, and with StorEn Tech’s advances in redox flow battery design, we anticipate that they’ll also be versatile enough for widespread residential use, in addition to use in industrial applications.
