- The EUROfusion consortium announced records results on fusion energy technology which is the clearest demonstration in a quarter of a century of the potential for fusion energy to deliver safe and sustainable low-carbon energy.
- Researchers from the EUROfusion consortium – 4,800 experts, students and staff from across Europe, co-funded by the European Commission – used the Joint European Torus (JET) device to release a record 59 megajoules of sustained fusion energy.
Fusion, the process that powers stars like our sun, promises an inherently safe, near-limitless clean electricity source for the long term, using small amounts of fuel that can be sourced worldwide from inexpensive materials. The fusion process brings together atoms of light elements like hydrogen at high temperatures to form helium and release tremendous energy as heat, which can then be converted into electricity.
The achievement on JET, the largest and most powerful operational tokamak in the world at the UK Atomic Energy Authority (UKAEA) site in Oxford, more than doubles the previous fusion energy record of 21.7 megajoules set there in 1997. It comes as part of a dedicated experimental campaign designed by EUROfusion to test over two decades’ worth of advances in fusion and optimally prepare for the start of the international ITER project.
The record and the scientific data from these crucial experiments are a major boost for ITER, the larger and more advanced version of JET. ITER is a fusion research project based in the south of France. Supported by seven members – China, the European Union, India, Japan, South Korea, Russia and the USA – ITER aims to demonstrate the scientific and technological feasibility of fusion energy.
As pressures mount to address the effects of climate change through decarbonising energy production, this success is a major step forward on fusion’s roadmap as a safe, efficient, low carbon means of tackling the global energy crisis.
Tony Donné, EUROfusion Programme Manager (CEO), said:
“This achievement is the result of years-long preparation by the EUROfusion team of researchers across Europe. The record, and more importantly the things we’ve learned about fusion under these conditions and how it fully confirms our predictions, show that we are on the right path to a future world of fusion energy. If we can maintain fusion for five seconds, we can do it for five minutes and then five hours as we scale up our operations in future machines.
“This is a big moment for every one of us and the entire fusion community. Crucially, the operational experience we’ve gained under realistic conditions gives us great confidence for the next stage of experiments at ITER and Europe’s demonstration power plant EU DEMO, which is being designed to put electricity on the grid.”
