Honeywell & ESS to collaborate on development of iron flow battery storage

September 27, 2023

Honeywell has entered a strategic collaboration with ESS to “advance technology development and market adoption” of iron flow battery (IFB) energy storage systems. 

Honeywell has made an investment in ESS as part of the collaboration.

The relationship builds upon each company’s involvement in the development of energy storage systems, and brings together ESS’ patented IFB design with Honeywell’s advanced materials and energy systems expertise.

A Honeywell/ESS statement said: “As the shift to renewable energy accelerates, challenges associated with the intermittency of wind and solar energy are becoming more apparent. Safe and sustainable IFB technology enables the transition to clean energy using Earth-abundant materials – iron, salt and water – to provide energy storage without reliance upon limited minerals such as lithium, cobalt or vanadium.”

Bryan Glover, chief growth officer, Honeywell Performance Materials and Technology (PMT) group, commented: “The demand for long-duration energy storage represents a compelling market opportunity within the energy transition and the combination of Honeywell and ESS technology can accelerate decarbonisation for the commercial, industrial and utility sectors. Our strategic collaboration with ESS will accelerate Honeywell’s ability to bring comprehensive solutions to our customers while working to advance long-duration energy storage across all industries requiring expansive energy storage.”

Eric Dresselhuys, CEO of ESS, added: “Today, we are creating superior technology in the critical long-duration energy storage industry. Combining ESS’ innovative technology and deployment experience with Honeywell’s storage and control system expertise will enable us to drive the clean energy transition and deliver value to our customers, shareholders and communities.”
