Summary
Carbon dioxide (CO2) capture from air is considered an important negative emissions technology to mitigate global warming. Current sorbent-based CO2 capture processes are prohibitively expensive because the sorbent must be regenerated via an energy-intensive step to release the captured CO2. Once released from the sorbent, the captured CO2 must also be compressed and transported to sites for storage, which further reduces efficiency. An ideal CO2 capture technology would be both high-capacity and energy-efficient, while simultaneously converting the waste CO2 stream into a value-added product.
