Technology Description:

Teledyne Scientific & Imaging is developing a water-based, potassium-ion flow battery for low-cost stationary energy storage. Flow batteries store chemical energy in external tanks instead of within the battery container. This allows for cost-effective scalability because adding storage capacity is as simple as expanding the tank. Teledyne is increasing the energy and power density of their battery by 2-5 times compared to today’s state-of-the-art vanadium flow battery. Their safe, scalable, low-cost energy storage technology would facilitate more widespread adoption and deployment of renewable energy technology.

Potential Impact:

If successful, Teledyne’s new flow battery would provide a practical path to removing the cost barriers for grid-scale energy storage systems.

Security:

A more efficient and reliable grid would be more resilient to potential disruptions.

Environment:

Electricity generation accounts for over 40% of U.S. carbon dioxide (CO2) emissions. Enabling large-scale contributions of wind and solar power for our electricity generation would result in a substantial decrease in CO2 emissions.

Economy:

Increases in the availability of wind and solar power would reduce fossil fuel demand, resulting in reduced fuel prices and more stable electricity rates.
