Fusion for Energy (F4E) is the European Union’s Joint Undertaking for ITER and the Development of Fusion Energy. The organisation was created under the Euratom Treaty by a decision of the Council of the European Union in order to meet three objectives:

F4E is responsible for providing Europe’s contribution to ITER, the world’s largest scientific partnership that aims to demonstrate fusion as a viable and sustainable source of energy. ITER brings together seven parties that represent half of the world’s population – the EU, Russia, Japan, China, India, South Korea and the United States.

F4E also supports fusion research and development initiatives through the Broader Approach Agreement, signed with Japan – a fusion energy partnership which will last for 10 years.

Ultimately, F4E will contribute towards the construction of demonstration fusion reactors.

F4E is established for a period of 35 years from 19 April 2007 and is located in Barcelona, Spain.
