Dannie Pengin BeijingAt a laboratory in northern China, less than an hour away from Beijing, a team of scientists is working on a new technology with huge potential as a clean energy source: nuclear fusion.Advertisement
The spacious ENN Group campus in Langfang, Hebei province, is home to a cluster of experimental facilities. At its heart is a spherical device called the EXL-50U – a compact tokamak that uses a magnetic field to confine charged gas, or plasma, to fuse hydrogen nuclei.
On the day the South China Morning Post visited, engineers were installing new neutral beam – or heating – systems to increase its plasma temperature.
Chief engineer Yang Yuanming said they aimed to get the plasma to 100 million degrees Celsius (180 million degrees Fahrenheit).
To achieve fusion, light atoms must be heated to extremely high temperatures and confined long enough to fuse them into heavier atoms. The energy released when this happens could then potentially be converted into vast amounts of clean electricity.
