As we look toward a sustainable energy future, one promising avenue is nuclear fusion. Recently, the UK announced a significant investment in a prototype fusion power facility, aiming to have it operational as a commercial power plant by 2040. This is an exciting development because, as of now, fusion power remains a theoretical concept.
Nuclear fusion is the process that fuels stars, including our Sun. It involves merging isotopes of light elements, like hydrogen, under extreme temperatures and pressures found in stellar cores. In these conditions, gases such as helium and hydrogen exist in a plasma state. For fusion to occur, the atomic nuclei must rearrange, typically involving heavy hydrogen isotopes like deuterium and tritium. This rearrangement produces helium atoms, neutrons, and a substantial amount of energy.
To mimic these stellar conditions on Earth, we need to create plasmas by heating gases to extremely high temperatures and densities. Various facilities are working on this, including ITER, an international fusion collaboration involving China, the EU, India, Japan, South Korea, Russia, and the U.S. Since 1985, ITER has aimed to produce fusion energy that could power the world. If successful, fusion energy promises to be a clean and virtually limitless energy source.
The UK government has committed £220 million to develop its own fusion facility, intensifying a decades-long race. Despite the potential of fusion energy, we have yet to achieve a point where the energy output from fusion exceeds the energy input required to start the reaction. Until then, fusion energy remains an unviable commercial option.
The UK’s prototype, known as the Spherical Tokamak for Energy Production (STEP), is the first step in this ambitious project. If approved, constructing the power plant could cost billions of pounds. STEP aims to innovate by using a different approach than ITER, specifically a smaller, more spherical tokamak. A tokamak is a device used to contain plasma for fusion reactions. The UK hopes this design will be more cost-effective compared to ITER’s larger, donut-shaped tokamak.
While STEP’s innovative approach carries risks, it also offers the potential to enhance energy yield with a smaller initial investment. The UK is launching this project amid uncertainties related to Brexit and its involvement with ITER. The EU is a major contributor to ITER, so the UK’s exit from the EU could pose challenges to its fusion innovation efforts. However, each of the seven ITER partners is also pursuing commercial reactors independently.
With ongoing efforts and international collaboration through ITER, there is hope to make fusion energy a reality sooner rather than later. While 2040 is an ambitious target, such bold initiatives are necessary to achieve a sustainable future for humanity.

We’re exploring the future of sustainable energy on our planet, and there are many potential directions we could take. The UK recently made a significant move by announcing a substantial investment in a prototype fusion power facility that could be operational as a commercial power plant by 2040. This is exciting for several reasons, one being that fusion power is not yet a reality.
Nuclear fusion is the process that powers stars, including our Sun. The term ‘fusion’ refers to the merging of isotopes of very light elements, such as hydrogen, under the extreme temperatures and pressures found at the center of stars. Under these conditions, gases like helium and hydrogen exist as plasmas. For a fusion reaction to occur, the nuclei of the atoms involved must change in their arrangement. Typically, heavy hydrogen isotopes like deuterium and tritium are used, which are subjected to extreme conditions. The result of this intense interaction is a rearrangement of their components, producing helium atoms, neutrons, and a significant amount of energy.
To replicate the conditions found in stars here on Earth, we need to create plasmas by heating gases to very high temperatures and densities. Various innovative facilities are working on this. One such facility is called ITER, which means ‘the way’ in Latin. It is a major international fusion collaboration that has been underway since 1985, with contributions from China, the EU, India, Japan, South Korea, Russia, and the U.S. The goal of ITER is to produce fusion energy that could power our world. If successful, fusion energy could provide clean and virtually limitless energy.
The U.K. government has dedicated £220 million for its own fusion facility, intensifying the race that has been ongoing for several decades. Despite the promise of fusion energy, we have not yet reached a point where the energy produced by the fusion reaction exceeds the energy required to initiate the reaction. Until we achieve this, fusion energy cannot be considered a viable commercial option.
The U.K. prototype fusion facility is named the Spherical Tokamak for Energy Production, or STEP. The first step in making STEP a reality is designing the plant. If the project is approved, building the power plant could cost billions of pounds. STEP aims to innovate by pursuing a different approach than ITER, specifically a different type of tokamak. A tokamak is a common design for the central machine of a potential magnetic fusion reactor, where plasma is created and fusion occurs. The proposed U.K. facility will utilize a smaller, more spherical tokamak, which they hope will be more cost-effective. In contrast, ITER’s plans involve a larger donut-shaped tokamak, which has been more thoroughly studied.
While STEP’s innovation carries some risk, it also presents an opportunity to potentially enhance energy yield with a smaller initial budget. It’s noteworthy that the UK is announcing this ambitious project amid uncertainty surrounding Brexit and its involvement with ITER. The EU is a key contributor to ITER, so if the U.K. exits the EU, it may face challenges in fusion innovation. However, each of the seven ITER partners is also exploring commercial reactors independently.
With these efforts and the ongoing international collaboration of ITER, there is hope to make fusion energy a reality sooner rather than later. While 2040 is an ambitious target, it may take such bold initiatives to achieve a sustainable future for humanity on this planet.
