- Additional information
- Calcium looping used for CO2 capture has high thermodynamic efficiency, but sintering causes capture capacity of standard sorbents to degrade by 60% over 15 cycles. By contrast, this new material exploiting reversible phase change retains capacity >95% of the original over 15 cycles and has potential for energy and industrial applications including solar thermal energy storage. Work led to Fennell being invited to be £6 million UK CCS Research Centre deputy director, where similar materials have been trialled at 100 kW scale.
