But bringing them to market will require new policies and regulations, and the nuclear industry must win public trust by addressing concerns over cost, safety, and waste. The amount of waste is relatively small because nuclear fuel is very dense and very little of it is required to produce immense amounts of electricity. Fusion mimics the process that powers the sun, creating massive energy without carbon emissions or long-lasting radioactive waste.
Inside a doughnut-shaped machine called a ‘tokamak,’ hydrogen isotopes will collide at enormous speed, fusing into helium. One day in the early 2030s, an engineer at a newly constructed power plant near Richmond, Virginia, in the United States, will press a button.

AI and nuclear fusion
The same resurgence can be seen with the origins of fusion research in the stellarator, replaced with the tokamak due to seemingly insurmountable difficulties at the time. The resurgence of the electric vehicle could prove similar to another source of innovation, this time in fusion science. Fusion also is the critical driver for enabling exciting artificial intelligence applications powered by energy-hungry data centres.

In 1968, scientists in the Soviet Union released the results of their tokamak machines, which were simpler to make, as part of the magnetic field cage is created by a strong current flowing in the plasma. The stellarator concept was an elegant solution to a fundamental problem in fusion research but it was challenging to build such a device to the precision needed. The arrangement would allow the plasma to confine long enough to make fusion happen. And since then, a frenzy of research and a wide range of new electric models have hit the market.

Australia, Germany and Japan are also pursuing fusion, according to Reuters. Kerry’s announcement followed the news of Britain and the US signing a cooperation agreement on fusion in November 2023. By using reinforcement learning, scientists were able to predict plasma tearing in the tokamak reactor DIII-D at the National Fusion Facility in San Diego, which would disrupt the reaction. Artificial intelligence could help solve a problem faced by the biggest magnetic fusion facility in the US, according to research published in February 2024 in the journal Nature.
Challenges for nuclear fusion researchers
Modelling the impact of fusion power — which has been compared to the discovery of fire fusion markets review and called “the last energy source humanity will ever need” — is challenging. DeepMind is also developing an AI pilot to control magnetic configurations, optimize fusion power and manage heat load for CFS’s SPARC reactor outside Boston. Early power-purchase agreements from end users such as Google, global energy company Eni and Microsoft signal rising industry confidence. Fusion, the process that powers the sun and stars, promises nearly limitless energy without carbon emissions or long-lived waste, which has excited scientists since the 1950s. These are just a few of the ways affordable commercial fusion energy could reshape life on Earth as we know it, which is why it’s worth pursuing. But all that cold air takes a lot of electricity to generate, making the coldscape a significant contributor to the food sector’s carbon emissions.
‘Make or break’ moment for renewables targets, and other top energy stories
Iran is implementing power blackouts as it struggles with a shortage of natural gas ahead of the winter. Developers have submitted plans for what would be the world’s biggest renewable energy project in Australia. Fusion research is taking place across various projects around the world but its use as an energy supply is considered to be many years away.
Conducted by the Massachusetts Institute of Technology, the study projects that fusion generation will rise from 2 TWh in 2035 to 375 TWh in 2050, reaching nearly 25,000 TWh by 2100. At least 45 companies worldwide are pursuing commercial fusion and the IAEA reports that more than 160 fusion facilities are now operational, under construction or planned. US Energy Secretary Chris Wright has underscored AI’s emerging role by noting its potential to enable breakthroughs in materials science, digital modelling of stellar fusion processes and molecular dynamics.
Pioneering nuclear fusion
4 ways the private sector can empower utility resilience amid severe climate risks The heat and pressure cause expansion but any contact with the reactor walls instantly cools it and halts the fusion reaction. Major hurdles remain, however, before fusion becomes a staple of the energy mix. A recent report from Swiss company EconSight, which tracks technology trends and patents, shows China leading the field, filing 67% of world-class fusion patents between 2016 and 2023, compared to 19% in the US and 5% in Europe. Since the 1980s, 33 nations and thousands of engineers and scientists have collaborated to build and operate a “tokamak” – a magnetic fusion device – as part of the ITER project, the world’s largest fusion experiment.
South Korean nuclear fusion reactor sets new record, and other technology news you need to know
The easing of inflation is expected to drive demand recovery in emerging markets, while increasing integration of AI technology is likely to attract buyers to premium devices. The global smartphone market is set to rebound 3% in 2024, according to a new report from Counterpoint Research. The World Economic Forum’s Centre for Health and Healthcare works with governments and businesses to build more resilient, efficient and equitable healthcare systems that embrace new technologies.
The long-due rebirth of the stellarator
MIT found that incorporating fusion into New England’s grid would cut annual energy costs by $36 billion — or 7% — by 2050. One way to understand fusion’s potential global economic impact is to look at a single market. The 10 countries that score the highest in terms of readiness account for only 2.6% of global annual emissions. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.
In the rural northeast, heat pumps, in combination with rooftop solar, are increasingly common, moving residents away from burning fuel and firewood. Right up against the arctic circle in Norway, nearly two thirds of homes rely on heat pumps to stay warm, and just over 40% have them in Sweden and Finland. But, as widespread adoption in Scandinavia over the last ten to fifteen years has shown, heat pumps can operate in frigid temperatures. In the past, the biggest hurdle to actually getting a heat pump has been cost. During the summer, the process can be reversed, moving heat out of the house in order to cool it.
South Korean nuclear fusion reactor sets new record
The global impact of electricity from fusion will be huge. In 2013, Lockheed Martin showed how compact fusion could meet global electricity consumption (44,000,000 GWh per year) by 2045. The JET tokamak at Culham Laboratory achieved 16MW of fusion power in 1997 with 24MW of input power. A nuclear fusion reactor in South Korea has set a new record, superheating a plasma loop to 100 million degrees Celsius for 48 seconds. Stellarators to return as key fusion energy research concept after tokamak focus. The global race for commercial fusion is on while the fusion-powered future is just beginning.
Given the difference in the maturity and level of development of these technologies, let’s unpack the status of each and the expected outlook. Without that, future winters will be just as chaotic and damaging, from both a social and climate perspective, as this year’s already is — if not worse. As more cities follow San Francisco and San Jose in banning gas hookups for new construction, heat pumps will be the de facto replacement system.
The world’s mindset will shift from energy as a constraint to limitless energy, reshaping the geopolitics of energy in its wake. From the United States to the UAE, governments are investing serious resources — in fusion R&D and commercialization. Extending this 7% price reduction across all energy consumption in the United States could save consumers $119 billion per year and help curb inflation, as energy costs are a significant driver of consumer prices. But these energy sources are inherently variable; the wind doesn’t always blow and the sun doesn’t always shine. That’s what the MIT Energy Initiative did using New England’s electrical grid as its case study. Benchmarking progress is essential to a successful transition.
A gallon of seawater (3.8 litres) could produce as much energy as 300 gallons (1,136 litres) of petrol. The process, which requires temperatures of approximately 72 million degrees Fahrenheit (39 million degrees Celsius), produces 17.6 million electron volts of energy. Recent surveys indicate that technology is now the primary driver of change and disruption for businesses across sectors and leaders will need to be equipped with a new leadership toolkit to adapt to and fully capitalize on these deep and structural changes. Estimates put the country’s fusion budget at around $1.5 billion a year – almost double that allocated by the US government to research in 2024.
