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.
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.
Ben Owens, General manager of Honeywell Sustainable Technology Solutions, said:
- 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
- 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 goals
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 MWh starting in 2023.
The company recently committed to achieve carbon neutrality in its operations and facilities by 2035.
