Agora Energy Technologies Ltd
As part of the Impact Canada Charging the Future Challenge, Agora successfully developed a non-metal CO2 rechargeable flow battery (CRB) designed to use captured carbon from flue gas emissions to store renewable electricity generated on-site. The battery, developed to use CO2 sourced from major industrial emitters (including cement, steel, petrochemical, aluminum manufacturers, coal and natural gas fired power plants), is safer and more affordable than competitors, while also reducing GHGs.
This is a first large-scale long-duration energy storage flow battery technology that uses carbon dioxide as an active battery material. This type of battery offers high energy densities, low cost, temperature swing resilience, and excellent durability.
“This Challenge was of paramount importance as the developmental fund to our company. We were able to advance our novel technology from a small half-cell scale to 300 times larger electrode area and to attract the interest of global partners, major companies in the renewable energy and industrial sectors, as well as investors.” – The team at Agora Energy Technologies
