58 Model The carbon capture model is dependent on the usage of the Central Utility Plant (CUP), and the rate at which it combusts natural gas. Initial values for CO2 captured per year are based on stateof-the-art capture efficiencies scaled to 2023 levels of plant emissions. Ideally, as the loads provided by the CUP are replaced with other technologies, the post-combustion capture scenario will proportionally scale down total CO2 captured per year, but the capital expenses have economies of scale – building and using equipment that can capture more CO2 will cost less per ton than a pilot system or one that does not operate for its useful life. However, the model assumes that the CUP will continue to operate at current levels, and levelized costs align with US Department of Energy targets and IPCC projections. Key Recommendations Post-combustion capture is a mature technology with the ability to scale to meet the level of emissions produced by the Central Utility Plant. Facilities should conduct detailed process analysis to determine the feasibility of implementing a pilot post-combustion capture system with campus energy, steam, and space constraints. Atmospheric CO2 capture and geological storage in New England are less proven technologies, but MIT’s leadership in investing in these spaces will show a commitment to the types of technology necessary globally. As an institution of innovation, the University should not shun proven, natural-based carbon removal techniques, but should pursue engineered solutions as well.
