Scientists in Europe have just sent waves around their nuclear energy, placing the world in a position where there is hope for clean energy. The donut-shaped box is called Tokamak, with temperatures reaching a good 150 million degrees Celsius. These temperatures are hotter than the sun’s core itself. The groundbreaking experiment was conducted in France at CEA’s WEST fusion reactor.
The CEA’s WEST machine managed to sustain a plasma for over 22 minutes on February 12. It broke the previous record for plasma duration using a tokamak in the process. This advancement gives hope that fusion plasmas can be stabilised for longer periods of time in devices like ITER and shows how our understanding of plasmas and our ability to manage them technologically over longer periods of time are maturing.
How the energy crisis could be solved by nuclear fusion
I am sure you are aware that we are in an era where everyone is trying to find ways to solve the energy crisis in the global community. If it is not about energy being expensive, it is also about reducing carbon emissions produced by substances such as fossil fuels. Therefore, nuclear fusion works by releasing massive amounts of energy through the combination of hydrogen atoms.
The advantage of this and why it is being pursued is that it does not emit any carbon emissions, gas or utilised fuels such as hydrogen, which is commonly known to only emit water. Maintaining the extreme conditions required for fusion to occur—in particular, maintaining plasma stability at extremely high temperatures—has traditionally been the most difficult task.
Europe is leading the world towards a fusion race
Fusion energy is also common in other countries that are fighting for sustainability, such as the U.S., China, and Japan, as they are working at their own scale and capacity. Europe, on the other hand, has joined the team, and its WEST tokamak is now leading. By doing this, it is setting the standards, showcasing the most sophisticated plasma control yet.
This development is especially important for the largest fusion experiment in the world, ITER (International Thermonuclear Experimental Reactor), which is presently being constructed in France. ITER’s capacity to produce large-scale, sustainable fusion energy will be directly impacted by the lessons learnt from WEST, which could render fossil fuels obsolete in the ensuing decades.
The challenge that Europe is facing to make this a reality
A report by New Atlas states that getting atoms to fuse is not the difficult part. That is a rather straightforward bench experiment in the lab. Establishing the ideal circumstances for the fusion reaction to be self-sustaining with net energy production is the challenge. This entails maintaining a high-energy plasma stable for at least 10 seconds, reaching temperatures of 100 to 150 million °C (180 to 270 million °F), and applying pressures of five to ten atmospheres at the reaction site.
Does this mean we are within the infinite energy era?
All we can say is we are getting closer. This is because fusion power plants still need years to be fully secure and established. If fusion can be successfully manufactured at a large scale, there is an assurance that the global energy crisis will come to an end, and we will not depend on the toxic resources we have been using for the past decades that have harmed the environment.
Europe has proved to us that we are closer than ever before because of this breakthrough, all because of a donut-shaped enclosure that can reach the universe’s most severe temperatures. However, it seems unlikely that fusion technology would significantly contribute to reaching net-zero carbon emissions by 2050, considering the infrastructure required to generate this energy on a big scale.
