Product Features & Capabilities
- Molten-borate carbon capture materials
- High-temperature CO2 capture at 800–1200°C
- Capture efficiency over 90% in boiler environments
- Compatible with existing industrial furnaces and kilns
Use Cases
Capture CO2 from cement kilns at 1200°C; Remove emissions from steel furnaces operating at 1400°C; Apply in natural gas combined cycle plants (NGCCs); Enable BECCS in bioenergy facilities; Deploy in heat and power plants (CHPs)
Other Considerations
Developing first molten-salt capture for high-temperature industrial heat; Targets cement, steel, and power generation sectors; Operates at 800–1200°C temperatures; Reduces energy losses by over 60%; Cuts capture costs in half; Partners with industrial heat process experts; Active in DEMO (D-1) project for pilot validation
