400-kWh Honeywell flow battery prototype will test at Duke Energy site

Honeywell is working on a new flow battery design with a non-flammable electrolyte that will be tested for the first time by Duke Energy at its Emerging Technology and Innovation Center in Mount Holly, North Carolina.

“Duke Energy has been following power battery technology for a number of years and is interested in the advancements Honeywell is pursuing,” said Tom Fenimore, director of Smart Grid Emerging Technology and Operations. “Our Emerging Technology and Innovation Center is an ideal testing ground to study this technology.”

Honeywell’s new technology can store and discharge electricity for up to 12 hours, which is longer than the duration of lithium-ion batteries, which often only discharge for up to 4 hours. The battery is designed with recyclable components and should not deteriorate over time. It maintains system performance and provides a reliable and cost-efficient system for 20 years.

Honeywell will supply a 400 kWh unit to Duke Energy’s Mount Holly facility by 2022.

“With this flow battery, Honeywell has developed an innovative energy storage technology to meet future energy storage needs beyond current technologies available on the market,” said Ben Owens, vice president and general manager of Honeywell Sustainable Technology Solutions.

The Honeywell Flow battery can also be combined with Honeywell’s unified system for process, business and asset management, Experion PKS, and its enterprise performance management solution, Honeywell Forge, for remote monitoring. The combination of technologies and renewables will provide an integrated energy storage solution for utilities and independent power producers to meet net zero carbon targets.
