The Surge of Flow Batteries in Renewable Energy Storage
The field of flow batteries is gradually gaining traction, presenting a promising avenue for economical and long-lasting energy storage—particularly beneficial for solar and wind energy systems. Unlike traditional batteries, flow batteries offer an environmentally friendly profile, making them a compelling alternative as we move toward sustainable solutions. In an exciting development within the circular economy framework, a U.S.-based startup specializing in flow battery technology has initiated an unprecedented project aimed at repurposing decommissioned oil storage tanks as containers for renewable energy storage.
The Operational Principle of Flow Batteries
A flow battery operates by exploiting the interaction between two distinct fluids separated by a semi-permeable membrane. Besides this membrane component, the construction involves cost-effective elements such as tanks and pumps, which collectively constitute its assembly.
Vanadium has become the preferred choice for many flow battery systems owing to its ability to exist in multiple oxidation states. This characteristic not only streamlines supply chain processes but also satisfies the necessary chemical requirements of both fluids used in these systems. However, a significant challenge remains: there is currently insufficient domestic vanadium mining activity within the U.S., emphasizing opportunities for retrieving vanadium from industrial waste or co-production alongside other mineral extraction operations.
Challenges with Traditional Oil Tanks
A major obstacle arises when considering existing oil tanks for conversion; they are typically constructed from carbon steel that is prone to corrosion when exposed to conditions common in standard flow battery designs.
Pioneering New Solutions with Quino Energy
Nevertheless, there’s potential here through innovative approaches exemplified by Quino Energy—a California-based startup that may redefine how we think about both flow batteries and old oil infrastructure. This company shot into prominence earlier this year when it unveiled its water-based quinone-flow-battery system that utilizes quinones—organic molecules prevalent across various natural sources including biomass and coal tar.
In 2021, Quino secured $4.58 million funding from the U.S Department of Energy (DOE) aimed at expediting their transition from research phases into mass production capabilities; recent assessments indicate they have reached Technology Readiness Level 7—just two steps away from achieving high-volume commercial viability.
Diverse Applications Ahead
This December saw further affirmation of support when Quino announced another grant amounting to $2.6 million granted by DOE’s Advanced Materials and Manufacturing Technologies Office specifically dedicated towards demonstrating how carbon steel oil tanks can be efficiently converted into operational platforms for their novel flowing batter technology.
Aiming Towards Future Flow Battery Developments
The initial laboratory project will facilitate early detection of any technical hiccups while concurrently positioning Quino towards launching larger-scale operation plans targeting 200 kW / 2 MWh by late 2026—collecting extensive field performance data through until their projected conclusions around late 2028.
If successful outcomes are observed during this strategic rollout process—and given projections indicate ongoing declines within traditional petroleum sectors—it becomes evident that former tank farms could potentially emerge alongside green energies across America.
