Scientists at the UK Atomic Energy Authority (UKAEA) have successfully tested a world-first concept that could clear one of the major hurdles in developing fusion energy.

Initial results from UKAEA鈥檚 new 鈥楳AST Upgrade鈥� experiment at Culham, near Oxford, UK, have demonstrated the effectiveness of an innovative exhaust system designed to make compact fusion power plants commercially viable.

With no greenhouse gas emissions and abundant fuels, fusion can be a safe and sustainable part of the world鈥檚 future energy supply.

Fusion energy is based on the same principle by which stars create heat and light. Using a machine called a 鈥榯okamak,鈥� a fusion power station will heat a gas, or 鈥榩lasma鈥�, enabling types of hydrogen fuel to fuse together to release energy that can generate electricity.

A key challenge in getting tokamaks on the electricity grid is removing excess heat produced during fusion reactions.

Without an exhaust system that can handle this intense heat, materials will have to be regularly replaced 鈥� significantly affecting the amount of time a power plant could operate for.

皇冠体育app new system, known as a 鈥楽uper-X divertor鈥�, would allow components in future commercial tokamaks to last for much longer; greatly increasing the power plant鈥檚 availability, improving its economic viability and reducing the cost of fusion electricity. 皇冠体育app concept for the Super-X divertor originally came from the .

Tests at MAST Upgrade, which began operating in October 2020, have shown at least a tenfold reduction in the heat on materials with the Super-X system.

This is a game-changer for achieving fusion power plants that can deliver affordable, efficient electricity.

UKAEA is planning to build a prototype fusion power plant 鈥� known as STEP 鈥� by the early 2040s, using a compact machine called the 鈥榮pherical tokamak鈥�. 皇冠体育app success of the Super-X divertor is a huge boost for engineers designing the STEP device, as it is particularly suited to the spherical tokamak.

UKAEA is announcing the results at today鈥檚 official opening of the MAST Upgrade facility, where guest of honour, British astronaut Tim Peake, is creating his own artificial 鈥榮tar鈥� by running a plasma test on the machine.

MAST Upgrade is funded by the UK Government鈥檚 Department for Business, Energy & Industrial Strategy, the Engineering & Physical Sciences Research Council (EPSRC) and the EUROfusion consortium.

UKAEA鈥檚 Lead Scientist at MAST Upgrade, Dr Andrew Kirk, said:

皇冠体育appse are fantastic results. 皇冠体育appy are the moment our team at UKAEA has been working towards for almost a decade.

We built MAST Upgrade to solve the exhaust problem for compact fusion power plants, and the signs are that we鈥檝e succeeded.

Super-X reduces the heat on the exhaust system from a blowtorch level down to more like you鈥檇 find in a car engine. This could mean it would only have to be replaced once during the lifetime of a power plant.

It鈥檚 a pivotal development for the UK鈥檚 plan to put a fusion power plant on the grid by the early 2040s 鈥� and for bringing low-carbon energy from fusion to the world.

Science Minister Amanda Solloway said:

This is an incredible breakthrough for fusion energy in the UK. Just seven months since MAST Upgrade was powered up, it may already have found a solution to one of fusion鈥檚 greatest challenges.

Innovative projects like this one are crucial to cementing our status as a science superpower, and I am excited to see how it develops.

EPSRC Executive Chair, Professor Dame Lynn Gladden, said:

皇冠体育app UK has been a leader in the development of fusion energy for many years, strongly supported by EPSRC since the early 2000s. 皇冠体育appse first results from the MAST Upgrade project demonstrate that fusion as an energy source has the potential to radically change the world鈥檚 energy supply.
