Fusion can potentially provide a safe, abundant, zero-carbon-emitting source of reliable primary energy. Once developed, first-generation fusion plants may likely use a combination of abundant deuterium (an isotope of hydrogen) and lithium as fuel.
Commercial fusion energy has the potential to revolutionize the energy industry, help to achieve energy abundance and security, and help meet growing clean energy needs of the U.S. and the world. Fusion may also potentially provide a combined source of thermal energy and power for hydrogen production, industrial heat, carbon capture, and desalination. At the same time, fusion has both technology gaps (e.g., materials and fuel supply) and potential risks that need to be managed, like the generation of activated waste in structural materials requiring short-term storage as well as potential proliferation pathways. DOE stands ready to deliver innovations that not only bring fusion to technical and commercial viability but also help manage these risks.
DOE has been investing in fusion research for decades through the Office of Science (SC) Fusion Energy Sciences (FES) program to establish the scientific foundations for a fusion energy source. These efforts include support of international collaborations like ITER, as well as the National Nuclear Security Administration’s Inertial Confinement Fusion program to advance its Stockpile Stewardship mission. More recently, ARPA-E has targeted areas of potentially transformative fusion R&D with a focus on enabling timely fusion commercialization. DOE is now committed to bridging fundamental fusion research with applied research and the needs of the growing U.S. fusion industry, in support of the U.S. Bold Decadal Vision for Commercial Fusion Energy and as described in our Fusion Energy Strategy 2024 and the FES Building Bridges vision document.
