Do you suppose that the men who manually shovelled massive quantities of coal into the fire would’ve ever imagined that someday, exponentially more power could be generated with just a fraction of the fuel they were throwing into the furnace? That day has arrived.

This week, the world of nuclear fusion has been a sizzling cauldron of excitement. Following hot on the heels of the American’s Inertial Fusion breakthrough — an experiment where a fusion reaction released more energy than it consumed — scientists in the UK have just announced a record-breaking energy output from their own fusion experiment.

In a test that lasted five remarkable seconds, Joint European Torus (JET) squeezed 69.26 megajoules of energy from a mere 0.21 milligrams of fuel — that’s equivalent to the energy you’d get from 2 kilograms of coal! JET achieved this impressive feat via nuclear fusion, the very process that fuels our Sun. The fuel it employed is a mixture of two types of heavy hydrogen: deuterium and tritium.

While this achievement is a world record, JET isn’t aiming to be the final power station. It’s a pathfinder, paving the way for larger prototypes set to launch next year that promise to generate 10-25 times the energy they consume.

But coming back to JET’s success, it’s a validation of the tokamak design, a donut-shaped chamber where powerful magnets hold the super-heated plasma that fuels the fusion reaction. Creating and controlling this plasma at temperatures exceeding 100 million degrees is no mean feat, and JET has tackled the two key challenges:

Taming the heat: The intense energy released by the plasma can damage the chamber walls. JET has demonstrated techniques to “soften” this heat, protecting future fusion machines.

Keeping it stable: Bursts of energy can also wreak havoc. JET has shown how to control the plasma edge, preventing these bursts and ensuring smooth operation.

These are not just theoretical solutions — JET has tested them in a real-world environment using the same fuel mixture (deuterium and tritium) that will be used in future power stations. This adds a crucial layer of confidence to the entire fusion endeavour.

While a commercial fusion power plant is still decades away, these breakthroughs are like stepping stones across a river, each one bringing us closer to the other side. The UK’s achievement, coupled with the recent American success, demonstrates that there are multiple paths to this clean energy future.

Scientists hope that with continued experimentation and collaboration can refine these technologies and help us move towards a cleaner world powered by the stars, right here on Earth.
