Non-flammable flow battery to be field tested at Duke Energy’s Mount Holly, N.C. facility for large-scale deployment for diverse energy storage solutions
Sustainable solution uses wind and solar to reduce carbon emissions and lower costs
DES PLAINES, Ill., Oct. 26, 2021 – Honeywell (NASDAQ: HON) today announced a new flow battery technology that works with renewable generation sources such as wind and solar to meet the demand for sustainable energy storage. The new flow battery uses a safe, non-flammable electrolyte that converts chemical energy to electricity to store energy for later use while meeting the environmental, longevity and safety objectives of utilities.
Honeywell’s new technology delivers greater flexibility and extended duration for utilities. The battery stores energy that can be used when wind and solar are absent, in the event of power outages and when power grids are at capacity. It can store and discharge electricity for up to 12 hours, exceeding the duration of lithium-ion batteries, which can only discharge up to 4 hours. The battery is designed with recyclable components and does not degrade over time. It maintains system performance, providing a reliable and cost-efficient system for 20 years.
The flow battery technology will be tested by Duke Energy at its Emerging Technology and Innovation Center in Mount Holly, N.C. The company has more than a decade of experience testing various battery chemistries and has deployed numerous large-scale energy storage projects across the country.
Honeywell will deliver a 400-kilowatt-hour (kWh) unit to Duke Energy’s facility in Mount Holly in 2022. If the battery is deployed at scale, it will reduce the use of Duke Energy’s fossil-fuel power plants by utilizing solar and wind. These renewable generation sources are increasingly cost competitive versus traditional fossil fuels and represent over 70% of new power generation. Honeywell aims to deploy a utility-scale pilot project of 60-megawatt-hours starting in 2023.
“With this flow battery, Honeywell has developed an innovative energy storage technology to answer upcoming energy storage needs beyond the current technologies available on the market,” said Ben Owens, vice president and general manager, Honeywell Sustainable Technology Solutions. “As utilities and corporations seek cost-effective alternatives to coal-fired plants with long-duration energy storage solutions, they are switching to renewable energy targets that work around the clock to reduce carbon emissions. By partnering with Duke, we can implement this innovate energy storage technology at scale and bring to market a revolutionary flow battery to meet growing energy storage demands while assisting companies in meeting their carbon neutral …….
