The report defines clean firm generation as dispatchable, low-emission electricity sources that do not rely on weather, including nuclear fission, fusion, geothermal, and carbon-capture-enabled fossil or bioenergy. It argues that integrating these technologies can significantly lower the total amount of wind, solar, and storage capacity needed, thereby reducing land use, critical mineral requirements, and overall system costs. The authors identify a 'missing middle' or 'valley of death' in financing for these capital-intensive projects and propose a multi-layered policy approach—combining RD&D, direct procurement, and technology-neutral targets—to achieve systemic bankability.
