Advances in research project IBUMECO 2 : project and process description, methodology, and goals expected

In this work, the research project IBUMECO 2 is presented for the first time. This project rises as a need to implement negative emissions technologies and circular economy approaches in our current energy production system. The overall goal of the project is the integration of CO 2 capture and utilization in biogas upgrading plants in combination with membrane technology for solvent regeneration. The integration of CO 2 capture and utilization in biogas upgrading plants is pivotal for two main reasons: (1) it allows to obtain biomethane, a potential substitute of natural gas; (2) the utilization of the CO 2 contained in biogas makes the idea a negative emission technology. The implementation of membrane technology for solvent regeneration makes the process affordable and includes it in a circular economy framework. In this paper, the project and the process are deeply described, including potential technological improvements identified by a state‐of‐the‐art, the methodology and goals expected. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
