Carbon capture from point sources and negative emission technologies such as direct air capture and biomass gasification with carbon capture are both required to achieve the net-zero carbon emission targets in 2050.
Point-source carbon capture
The mixed ionic-electronic conducting (MIEC) membranes developed in our group can be integrated thermochemically with various energy conversion (e.g., integrated gasification combined cycle) and chemical production processes (e.g., methane partial oxidation) to facilitate carbon capture.
Direct air carbon capture
We are developing an open-source distributed direct air carbon capture technology with OpenAir.
The captured CO2 can be effectively converted back into fuels utilizing the oxygen permeable membrane technology (read more on MIT News) or high temperature electrolysis with methanation (read our paper on Applied Energy).
