A Monumental Nuclear Fusion Energy Breakthrough Achieved
February 8, 2024
Big news from the world of energy research as scientists and engineers near Oxford, England, make a significant breakthrough in nuclear fusion energy. They’ve set a new record that further realizes the potential to harness this futuristic power source.
The team used a piece of high-tech equipment named the Joint European Torus (JET). Picture a huge, donut-like machine, known as a tokamak. It cranked out an amazing 69 megajoules of fusion energy for a full five seconds, using only 0.2 milligrams of fuel.
Nuclear fusion is the process that fuels the sun and other stars, and it’s been becoming accepted as a source of clean energy. With decades of research behind it, the idea is to replicate this process on Earth. If it can be done right, the result would be the ability to generate tons of energy with a mere trifle of fuel while emitting zero carbon — a win-win for society and the planet.
The team used two types of hydrogen — deuterium and tritium — to fuel the tokamak. They then heated the machine to 150 million degrees Celsius (10 times hotter than the sun’s core) to initiate fusion. This fusion process creates helium and releases massive amounts of heat, which can then be harnessed to generate electricity.
For context, JET has been operational for over 40 years, and this is their swan song experiment. The success bodes well for other fusion projects, like ITER, the world’s largest tokamak under construction in southern France, and DEMO, a subsequent project aiming to produce larger amounts of energy.
However, it’s important to realize that commercializing fusion energy still has a long way to go and many hurdles to overcome. For one, the energy used in the experiment was more than the energy it produced. There are also several challenges in building a fully functioning fusion power plant.
Still, progress is progress, and this landmark achievement could have huge implications for the future energy landscape. Despite the challenges ahead, investment in fusion is increasing, and tangible strides are being made.
This is a critical development since the European Union’s climate and weather monitoring service Copernicus confirmed that global warming had crossed the 1.5-degree Celsius threshold over a yearly period for the first time. This grim reminder underscores the urgency of our transition away from fossil fuels and toward sustainable, clean energy solutions while we’re still in the race against time to prevent catastrophic levels of global warming.
