This project focuses on negative emissions technologies (bioenergy with carbon capture and storage, direct air capture, etc.) and hydrogen in a portfolio of mitigation options, including strategies to advance the carbon capture and storage (CCS) option. Researchers will update/improve the accuracy of models for the deployment of negative emissions technologies and hydrogen and other competing/complementing options based on recent experience, literature and data; and use the MIT EPPA model to examine different long‑term scenarios to estimate the importance of factors influencing advanced technology deployment. Options for decarbonization in power generation, industrial, transportation and residential sectors will be assessed.
