The latest greatest utility-scale battery storage technology to emerge on the commercial market is the vanadium flow battery - fully containerized, nonflammable, reusable over semi-infinite cycles
Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources. Their advantage is that they can be built at any scale, from the lab-bench scale, as in the PNNL study, to the size of a city block.
The study, published in the journal Joule, reveals that the flow battery maintained its capacity for energy storage and release for over a year of constant cycling. A common food and medicine additive has shown it can boost the capacity and longevity of a next-generation flow battery design in a record-setting experiment.
Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design. In the everyday batteries used in phones and electric vehicles, the materials that store the electric charge are solid coatings on the electrodes.

China and Russia dominate the market for vanadium, the metal that makes flow batteries durable and easy to maintain. “The supply chain for vanadium is extremely precarious,” said Kara Rodby, a battery analyst at the investment firm Volta Energy Technologies. Still, flow batteries are making their debut in big real-world projects.
The work on flow batteries is part of a large program at PNNL to develop and test new technologies for grid-scale energy storage that will be accelerated with the opening of PNNL’s Grid Storage Launchpad in 2024.
