Fusion energy and ITER

Could fusion, the energy source of the sun and stars, be the energy of the future? Fusion has the potential to provide a safe, cost-efficient and sustainable solution to European and global energy needs. For this reason, the EU is part of one of the most ambitious energy projects in the world, called ITER in the south of France.

ITER is a unique project to build the world’s biggest fusion machine. By fostering innovation and international collaborations, the project creates economic growth and job opportunities while putting the EU in the lead of global fusion research.  Although a purely experimental device, ITER will help advance fusion energy technology for a greener and more sustainable energy mix.

The road to fusion

Fusion science and technology have a long history in Europe and their development was accelerated from 1957 by the Euratom Treaty, which established a European atomic energy community. Since then, European fusion research is better coordinated to make sure that the technology moves forward, as quickly as possible.

European fusion laboratories collaborate through a consortium called EUROfusion, in line with the long-term strategy set out in the European research roadmap to the realisation of fusion energy.

ITER is of key importance in the roadmap, particularly as it aims to prove the scientific and technological feasibility of fusion as a future energy source. Although ITER itself will not produce electricity, DEMO - the device that will follow - will likely model a real future fusion power plant and produce electricity. This in turn will pave the way for future commercialisation and use of fusion power, possibly from 2050 onwards.  

ITER governance and funding

The project stems from the ITER agreement, which was signed by China, Euratom (represented by the European Commission), India, Japan, South Korea, Russia and the USA in 2006.  Together, they govern the ITER Organization, which is responsible for constructing and managing the project.

Members have a domestic agency that manages their contributions. The EU’s domestic agency is called Fusion for Energy.

The European contribution to ITER is funded from the EU budget; for the period 2021 to 2027 the European Commission has proposed to contribute €6.07 billion to ITER.

The Broader Approach

In parallel to their collaboration on the ITER project, the EU and Japan are working together on three fusion-related projects.

The projects, all located in Japan, aim to complement ITER and accelerate the development of fusion power. The work includes the construction of an advanced fusion device, research into durable materials for use in future devices, and the setting-up of a remote operation room for ITER.

The cooperation was established by the signature of the Broader Approach Agreement in 2007 and a new, second phase of activities is being launched in 2020.

Fusion for Energy and industry engagement

The EU’s domestic agency, Fusion for Energy, established in 2007 and based in Barcelona, Spain,  is responsible for delivering Euratom’s contribution to the ITER project and the Broader Approach, and contracts businesses and research organisations in the EU to achieve this.

By participating in ITER, the EU makes substantial investment in European industry. More than €4 billion has already been invested in this way, which has had a strong and positive impact on the European economy in terms of producing economic growth and boosting employment.

Moreover, individual businesses that have produced components and provided services for ITER have reported being able to expand their facilities, upgrade equipment, and hire staff.
