Nuclear Fusion Global Market Report 2025

Nuclear fusion is the phenomenon where two light atomic nuclei merge to create a singular, heavier nucleus, resulting in the release of substantial energy. The replication of this process on an industrial scale has the potential to generate virtually limitless, clean, safe, and cost-effective energy on Earth.

The primary technologies employed in nuclear fusion are inertial confinement and magnetic confinement. Inertial confinement fusion (ICF) involves the rapid compression and heating of a small quantity of fusion fuel to create the necessary conditions for fusion. This technology utilizes fuels such as deuterium, tritium, helium-3, and proton boron to achieve controlled fusion reactions.

This nuclear fusion market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

The nuclear fusion market size has grown strongly in recent years. It will grow from $331.49 billion in 2024 to $351.11 billion in 2025 at a compound annual growth rate (CAGR) of 5.9%. The growth in the historic period can be attributed to energy security concerns, environmental sustainability, international collaboration, government funding and support, advancements in fusion research.

The nuclear fusion market size is expected to see strong growth in the next few years. It will grow to $479.5 billion in 2029 at a compound annual growth rate (CAGR) of 8.1%. The growth in the forecast period can be attributed to private sector investment, global energy transition, technological maturation, research and development initiatives, policy and regulatory support. Major trends in the forecast period include government support and funding initiatives, research on innovative fuel cycles, advances in plasma stability and control, R&D efforts in fusion materials and components, public awareness and education initiatives.

The growth of the nuclear fusion market is anticipated to accelerate due to increased government funding for nuclear energy. Nuclear energy is generated by splitting atoms in a reactor, producing steam to drive turbines and generate electricity. Numerous developed countries are investing in nuclear reactors, thereby boosting demand in the nuclear fusion market. For example, in January 2024, the Sunak Conservative government in the UK announced an extensive plan to quadruple the nation's nuclear capacity by 2050, targeting a total of 24 gigawatts (GW). This initiative, part of the Civil Nuclear Roadmap, aims to enhance energy independence and security, lower electricity bills, and create jobs within the nuclear sector. The government intends to invest up to £300 million ($389.5) in the domestic production of high-assay low-enriched uranium (HALEU) and is dedicated to constructing new large-scale reactors, alongside developing small modular reactors (SMRs) as part of this nuclear resurgence. Thus, increased government funding for nuclear energy is propelling the growth of the nuclear fusion market.

The anticipated growth in energy demand is poised to drive the expansion of the nuclear fusion market. Energy demand, representing the total energy needed by specific regions, sectors, or systems within a given timeframe, is on the rise globally. This surge in demand, coupled with the imperative for clean and sustainable energy sources, underscores the growing interest in nuclear fusion as a potential contributor to the energy landscape. As projected by ExxonMobil Corporation in August 2023, a US-based oil and gas corporation, the worldwide energy demand is expected to reach approximately 660 quadrillion Btu by 2050. This projection signifies an increase of around 15% compared to the levels observed in 2021. The escalating energy demand serves as a driving force for the growth of the nuclear fusion market, positioning it as a viable solution to address the increasing global need for sustainable energy sources.

Key players in the nuclear fusion market are forming strategic partnerships to address the intricate challenges of nuclear fusion energy production. These collaborations allow companies to leverage combined expertise, share resources, and foster technological advancements, thereby accelerating the path toward sustainable and commercially viable fusion energy. For instance, in January 2023, First Light Fusion, a UK-based fusion company, entered into an agreement with the United Kingdom Atomic Energy Authority, a government department in the UK, to design and construct 'Machine 4,' a facility aimed at hosting their new net energy gain demonstrator.

Prominent companies within the nuclear fusion market are increasingly engaging in strategic partnerships to foster innovation and enhance their market positions. Strategic partnerships involve leveraging the complementary strengths and resources of each company to achieve mutual benefits and overall success. An illustrative example is the collaboration between Focused Energy Inc., a U.S.-based energy harvesting company, and Lawrence Livermore National Laboratory (LLNL), a federally funded research and development center. In November 2023, they joined forces to develop target designs for inertial fusion energy. This strategic alliance aims to contribute to the advancement and assessment of isochoric compression target designs, furthering progress in the field of inertial fusion energy.

In March 2024, Vistra Corp, a US-based electricity generation company, completed the acquisition of Energy Harbor Corp. for an undisclosed sum. This acquisition enables Vistra to enhance its portfolio by adding approximately 4,000 megawatts of nuclear generation capacity and gaining around 1 million retail customers. Energy Harbor Corp., also based in the US, is an energy supplier that specializes in providing carbon-free and green electricity plans to residential and commercial clients across several states.
