Problem
Many carbon capture technologies struggle to operate efficiently at the high temperatures present in industrial processes like those found in boilers, kilns, and furnaces. This limitation hinders the ability to capture CO2 emissions directly from these sources, making it difficult for industries to meet climate goals.
Solution
Mantel provides carbon capture materials engineered to function effectively at the elevated temperatures of industrial exhaust streams. These materials are designed for direct integration into existing infrastructure, enabling the capture of CO2 emissions at the source. By operating at high temperatures, the technology reduces the energy penalty associated with cooling exhaust gases, leading to more efficient and cost-effective carbon capture. This approach allows industries to mitigate their environmental impact by preventing CO2 from entering the atmosphere.
Target Audience
The primary target audience includes industries with high-temperature industrial processes, such as manufacturing, power generation, and cement production, seeking to reduce their carbon emissions.
