Flow batteries are a type of electrochemical batteries that use externally stored electrolytes, making them cost less, safer, and more flexible and adaptable. They are particularly well-suited for grid storage needs. Flow batteries are not the same as lithium-ion batteries, which are commonly used in electric vehicles and portable devices for various applications.
Usually, when I talk about new battery technology, they tend to be concepts currently being developed in a lab, where they won't see the light of day for years. But flow batteries are already a reality. Fort Carson, a US military base, has contracted Lockheed Martin to build a 10 MWh redox flow battery to store its solar farm's energy.
The manufacturing of flow battery systems is the focus of the "$24.5 Million for Manufacturing Innovation" funding opportunity. Flow batteries are electrochemical batteries that use externally stored electrolytes, making them cost less, safer, and more flexible and adaptable. The funding opportunity will award up to $20 million for R&D projects in this area.
Flow batteries have long been considered the most flexible answer to grid scale energy storage, and modelling is a key component in their development. Recent modelling has moved beyond macroscopic methods, towards mesoscopic and smaller scales to select materials and design components.
