When we think of the future energyit is easy for us to think about renewables. Much of Europe has a while running with renewables, China is an expanding power and even some states in the United States They are seeing its benefits. However, the future lies in nuclear power. But not because of fission, but for the fusion. And China has just taken a giant step in the forecasts of its BEST program with a single objective.
Replicate the process that powers the Sun.
China and the ultimate energy. Fusion and fission are nuclear reactions that release energy from the nucleus of the atom, and That’s where their similarities end.. Briefly, fission consists of breaking the nuclei of heavy atoms such as uranium to release energy. It is the process that we use in current nuclear power plantsand decades ago we managed to make it something stable. Fusion is the reverse process: it joins light atoms to generate energy. It is tremendously unstable and the heat generated is enormous, but the process generates a much higher amount of energy.
Imitate that star power It is extremely complex, but we have been trying to replicate it for years for a very simple reason: it is estimated that it will offer almost unlimited energy and long-lasting waste-freesomething against which nuclear fission can’t compete. China is one of the countries that is pushing the development of nuclear fusion plants the most, so much so that it intends to put the first plant into operation a decade before its competitors.
EAST. It stands for ‘Experimental Advanced Superconducting Tokamak’, an experimental program that China has been developing since 2006 to test the viability of commercial fusion energy. After setting some records for temperature and operating time, in 2021 achieved continuous plasma operation for 17 minutes in which the core operated at 70 million degrees Celsius. They are five times the sun temperature and, although temperatures of up to 160 million degrees were previously achieved for 20 seconds, the ideal is to maintain a very high temperature for as long as possible.
Steps have continued to be taken and researchers recently discovered that the reactor could work at 165% of its maximum theoretical capacity without suffering disruptions. To contextualize, it is as if we have an engine designed to go at 200 km/h, but we discover that we can drive at 330 km/h constantly without it overheating. In short: China is taking steps to control the enormous challenge represented by the magnetic confinement of plasma.
BEST. The ‘Burning Plasma Experimental Superconducting Tokamak’, for its part, is the spearhead of its nuclear fusion program. If EAST is the proof of concept, BEST is the demonstration of feasibility. The EAST steps are those that will be replicated in BEST, a reactor built on a larger scale that will operate for a shorter period of time in a sustained manner, but under conditions of greater energy gain.
Goal: 2030. China began construction of the BEST in 2023 and hopes to complete it by 2027 to begin testing with plasma. If it goes well, the CFETR reactor will be the one that pours fusion energy into the grid. In a statement published by the state media Xinhuawe see that the intention is to generate electricity by 2030 and start do it commercially by 2035.
If the goal is reached, China will be the first country that will be able to commercially emulate the power of the Sun to light the “first nuclear fusion light bulb” in history. Although, of course, the United States and Massachusetts They also say that they will be the first.
They are not the only ones. If they reach the goal, it will be a fundamental step in achieving new generation energy, and they want to reach that future a decade before the rest of the countries, or so China suggests. In this race for nuclear fusion, the BEST is expected to begin operating commercially between 2030 and 2035. Meanwhile, in France there is the ITER. With 24,000 million euros in budgetis the most expensive international program in history, only surpassed by the Apollo Programthe International Space Stationhe Manhattan Project or the GPS system.
It aims to be very powerful, but has constant delaysa budget that has overflowed and an operational date that has not been fulfilled. In the United States, a private startup is building SPARCmuch smaller than ITER, but more profitable. United Kingdom has the STEPJapan JT-60SA and Russia the T-15MD Hybrid. Talking about dates is complicated, since there were tests that were expected to be obtained in 2025 and were not achieved… and there is talk of between 2040 and 2060 for the commercial viability of this energy “from the stars”, although the calendars have been readjusted.
China has turned new generation energy in a matter of stateand we will see if they meet their goal of starting production in 2030. And, although it seems that we have to put the artificial intelligence even in the soup, the enormous energy needs of this technology are encouraging advances in nuclear fusion. The joke that nuclear fusion energy always has 30 years to go may have come to an end.
