Abstract

Electrification to reduce or eliminate greenhouse gas emissions is essential to mitigate climate change. However, a substantial portion of our manufacturing and transportation infrastructure will be difficult to electrify and/or will continue to use carbon as a key component, including areas in aviation, heavy-duty and marine transportation, and the chemical industry. In this Roadmap, we explore how multidisciplinary approaches will enable us to close the carbon cycle and create a circular economy by defossilizing these difficult-to-electrify areas and those that will continue to need carbon. We discuss two approaches for this: developing carbon alternatives and improving our ability to reuse carbon, enabled by separations. Furthermore, we posit that co-design and use-driven fundamental science are essential to reach aggressive greenhouse gas reduction targets. (Figure presented.)

Funding

This Roadmap is the outcome of a workshop entitled Closing the Carbon Cycle: Opportunities in Energy Science, organized by seven Department of Energy, DOE, national laboratories and held at Pacific Northwest National Laboratory on July 18 and 19, 2022, with co-organization from Ames, Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge and SLAC National Laboratories. In attendance were representatives from ten national laboratories, 35 academic institutions, several government agencies and four companies. The authors are indebted to the agencies responsible for the funding of their individual and group research efforts, without which this work would not have been possible. These include the US DOE, Office of Science, Basic Energy Sciences, Chemical Sciences, Geosciences and Biosciences; DOE-Office of Science Basic Energy Science Materials Science and Engineering; DOE-Fossil Energy and Carbon Management (FECM); DOE-Energy Efficiency and Renewable Energy (EERE); DOE-EERE, Hydrogen Fuel Cell Technology Office (HFTO); DOE-EERE, Bioenergy Technologies Office (BETO); DOE-EERE, Advanced Materials and Manufacturing Technology Office (AMMTO); DOE-EERE, Industrial Efficiency and Decarbonization Office (IEDO); US Department of Agriculture National Institute of Food and Agriculture; and National Science Foundation.
