The UK's ambition for fusion energy

The UK government is firmly committed to establishing the nation as a global leader in fusion technology, viewing it as a critical component of future energy security and economic growth. This commitment is backed by considerable financial investment and a clear strategic direction.

Government investment and strategic goals

The UK government has pledged over £2.5 billion towards fusion research and development. This substantial funding is designed to accelerate research and development, foster investment, cultivate supply chains, and develop essential skills within the fusion sector. This includes Spherical Tokamak for Energy Production (STEP), a government-backed programme to build a prototype fusion power plant in the UK, where Tokamak Energy has been involved as part of the wider UK fusion supply chain.

The overarching goal is to position the UK to capture the economic benefits of rapidly advancing fusion technology, including innovation, the creation of secure, well-paid jobs, and the commercialisation of new fusion-derived technologies. Foreign Secretary Ed Miliband has stated, "Fusion has the potential to strengthen our energy security, create skilled jobs and drive growth here in the UK."

Oxfordshire: a hub for fusion innovation

Oxfordshire has emerged as a vital centre for fusion activity and related high-skilled clean energy jobs in the UK. The region is home to the UK Atomic Energy Authority (UKAEA) at Culham, which employs around 2,000 people, with a further 6,000 jobs supported across its supply chain. This region, part of the Oxford-Cambridge Growth Corridor, hosts around 500 companies linked to fusion, including Tokamak Energy, which employs over 300 people in the county. This concentration of expertise and industry makes Oxfordshire a significant hub for fusion innovation and a magnet for investment in advanced technologies.

Key players driving UK fusion development

The UK's pursuit of fusion energy is a collaborative effort, bringing together both domestic innovation and international partnerships.

Tokamak energy and private sector leadership

An Oxfordshire-based firm, Tokamak Energy, is at the forefront of private sector-led fusion development in the UK. The company has partnered with US firms Type One Energy and AECOM to form the UK Infinity Fusion Consortium. This consortium aims to develop the UK's first private-sector-led fusion power plant1. This initiative is intended to create a commercially credible fusion project that can attract private capital and align with the UK's broader fusion strategy.

Ross Morgan, Tokamak Energy’s Fusion managing director, has highlighted the transformative potential, stating, "Fusion will transform global energy markets as a clean, limitless, on-demand power source of the future."

International partnerships: UK-us collaboration

Collaboration with international partners is a cornerstone of the UK's fusion strategy. The UK and the US have deepened their cooperation on advanced nuclear technologies, including a formal fusion energy partnership and a landmark nuclear partnership. This strategic alliance aims to accelerate the deployment of commercial fusion power plants by strengthening cooperation on research and development, knowledge-sharing, and skills development. This collaboration includes a formal fusion energy partnership signed in 2023 and a landmark nuclear partnership agreed in 2025, boosting joint work between the two countries. In September, the UK and US will co-host the Global Fusion Policy Summit in London, bringing together countries, and fusion industry leaders and experts, to help accelerate fusion development and commercialisation.

The promise of fusion power

Fusion energy holds immense promise for a future powered by clean, abundant, and reliable sources.

Clean, limitless, on-demand energy

Fusion energy, which mimics the process powering the Sun, involves fusing light atomic nuclei to release vast amounts of energy. This process offers a low-carbon, secure, and virtually limitless energy supply. Unlike fossil fuels, fusion does not produce greenhouse gases, and it provides a constant, on-demand power source that is not reliant on environmental conditions, addressing the intermittency challenges of some renewable sources. Minister for Energy Michael Shanks emphasised that "Fusion is one of the most exciting technologies being developed in the UK today, with the potential to create skilled jobs, attract investment and generate virtually limitless energy."

Distinguishing fusion from fission

It is crucial to differentiate nuclear fusion from nuclear fission, the process used in traditional nuclear power plants. While both release energy from atomic nuclei, they operate on opposite principles and have distinct safety and waste profiles. Fission involves splitting heavy atoms, which produces long-lived radioactive waste and carries the risk of a runaway chain reaction.

In contrast, fusion combines light atoms, producing significantly less long-lived radioactive waste. The primary product of the fusion process is helium, an inert gas. Fusion reactors are considered intrinsically safe because they are not based on a chain reaction; if conditions are not precisely met, the reaction simply stops, eliminating the risk of a meltdown.

Economic and societal impact for the UK

The development of fusion power plants is expected to bring substantial economic and societal benefits to the UK.

Strengthening energy security

Fusion energy has the potential to significantly bolster the UK's energy security by providing a reliable, indigenous source of power. By reducing reliance on imported fossil fuels, fusion can help stabilise energy supplies and contribute to long-term energy independence. This strategic shift is vital for national resilience and economic stability in a volatile global energy market.

Creating high-skilled clean energy jobs

The UK's investment in fusion research and development is already supporting the creation of high-skilled clean energy jobs across the country, particularly in innovation hubs like Oxfordshire. The government's strategy aims to support over 10,000 UK jobs by 2030 through fusion-related activities. These roles span various fields, including science, engineering, manufacturing, and construction, fostering a new generation of experts and contributing to regional growth.

The future outlook for UK fusion

The path to commercial fusion energy is a long-term endeavour, but the UK is positioning itself to lead this transformative journey.

Accelerating commercialisation

While commercial fusion power is not an immediate solution to current energy crises, the UK government and private sector are actively working to accelerate its commercialisation. The goal is to move fusion from the laboratory to the grid, with the STEP programme aiming to build a prototype fusion power plant in the UK. This involves fostering a robust ecosystem of companies, developing strong supply chains, and creating regulatory frameworks that support the emerging fusion industry. The UK Infinity Fusion Consortium aims to develop the UK's first private-sector-led fusion power plant. Fusion is expected to become a multi-trillion-pound global market in the second half of the century, presenting a major long-term growth opportunity for the UK.

Towards an energy-abundant future

The long-term implications of successful fusion power are profound. It promises a future where energy is not a scarce resource but an abundant, clean commodity, fundamentally altering the global energy landscape. This vision of energy abundance aligns with Fuse Energy's core belief that humanity has the right to use more energy, not less, and its mission to deliver the abundant, clean energy the future requires. By championing and building towards a future where fusion power makes energy so abundant it stops being a concern, Fuse Energy positions itself as "the good timeline's energy company." This proactive approach, mirroring the UK's investment and private sector initiatives in fusion, demonstrates a refusal to settle for conventional energy limitations and instead builds towards a future with "power to play with."
