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. Stellarators to return as key fusion energy research concept after tokamak focus. As fusion power transforms the economics and geopolitics of energy, it will reshape industries and regions that need it most.
SDG 07: Affordable and Clean Energy
In a statement, the US Department of Energy hailed the breakthrough as a “historic, first-of-its kind achievement” that will provide “invaluable insights into the prospects of clean fusion energy.” If we as a society are going to electrify home heating and other residential appliances, we need affordable, carbon-free electricity to power them. The transition to nuclear fusion in the coming decade could provide just that. A nuclear fusion reactor in South Korea has set a new record, superheating a plasma loop to 100 million degrees Celsius for 48 seconds. Organic, sustainable food powered by fusion energy, harvested when it’s ripe and sold at an accessible price point, could offer another ripple effect of increased enthusiasm for eating tastier fresh foods and better health. That ability could come from commercial fusion energy, creating a game changer for desalination by taking the energy overhead costs of desal and cutting them to nearly zero.

In recent years, some have been questioning the possibility of a smaller way to fusion. The magnetic fusion approach uses strong magnetic fields to pressurize and trap the hot plasma fuel. And the stellarator’s re-emergence will bring advanced computing and additive manufacturing.
AI and nuclear fusion
- Fusion mimics the process that powers the sun, creating massive energy without carbon emissions or long-lasting radioactive waste.
- Unlike traditional nuclear power (fission), which splits atoms, fusion joins smaller atoms to make heavier ones.
- While achieving net-energy gain has long been a scientific challenge, progress is accelerating across multiple fronts, putting the technology on the radar of the World Economic Forum’s Global Future Council on Energy Technology Frontiers.
- And it will be the cheapest reliable power, and incidentally, the cleanest power too.
- If we as a society are going to electrify home heating and other residential appliances, we need affordable, carbon-free electricity to power them.
Inexpensive, plentiful power derived from a nuclear fusion-fueled grid could spell the end of heating-season chaos like we’re seeing this winter. Nuclear fusion power would revolutionize the energy sector — and one of the most environmentally impactful and increasing needs is in home heating and cooling. The US Department of Energy has announced a breakthrough on nuclear fusion, achieving a net energy gain for the first time, in a fusion experiment using lasers. But fusion power can make the prospect of electric heating via heat pumps a zero-emission future. With fusion energy, those emissions could disappear — and the dramatic drop in cooling costs would make tropical fruits and out-of-season produce easier on your wallet too. From the way we heat our homes to more water in times of drought, here’s just a glimpse of how fusion power could help change the world.
- What’s the World Economic Forum doing about the transition to clean energy?
- Fusion is the future of the global energy sector — the near future.
- 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.
- General Fusion in Canada, Helion Energy in the United States and others are investigating new approaches to fusion energy.
And for a long time, building stellarator coils to the required precision posed a major issue, putting the stellarator at another disadvantage. This challenge was especially true for stellarators with more complicated coil configurations than tokamaks. In December 2017, it set a new stellarator world record for fusion products. 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. fusion markets 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 Princeton Plasma Physics Laboratory (PPPL) was created based on his ideas. American scientist Lyman Spitzer developed the idea of the stellarator in 1951. And since then, a frenzy of research and a wide range of new electric models have hit the market. How financial regulators are using technology to protect consumers and strengthen the financial system Skills development is critical to bridging the global digital talent gap The world’s mindset will shift from energy as a constraint to limitless energy, reshaping the geopolitics of energy in its wake.
Nuclear fusion’s future, according to the woman leading the charge
Thanks to its success in advancing fusion technology, it operated for 40 years before entering decommissioning in October 2023. Microsoft President Brad Smith said Helion’s work “supports our own long-term clean energy goals and will advance the market to establish a new, efficient method for bringing more clean energy to the grid, faster”. “If we want to take this forward, public-private partnerships are going to be essential,” she said. Using laser beams, the amount of energy from the fusion reaction surpassed that concentrated on the target for an instant. In August 2023, scientists at the US Lawrence Livermore National Laboratory in California repeated a breakthrough they first made in December 2022, achieving a “net energy gain” in fusion ignition. It produced 69 megajoules of energy over five seconds – or enough energy to heat up to five hot baths, according to the BBC, triple what it generated back in 1997.
On the timescale for scaling to generate power
Factories could, for example, be located closer to the raw materials they rely on — or to the retail markets that goods are destined for — cutting down on transportation costs and carbon emissions. More recently, factories still need some proximity to high-wattage transmission lines that can supply large quantities of electricity. As technology developed in the early 1800s, turbine systems could power mills of all sorts.
How AI will help get fusion from lab to grid by the 2030s
But what’s next for this vital technology in the age of power-hungry AI systems? To help address that, TAE recently spun off a new company called TAE Power Solutions to create advanced technologies designed to deliver faster charging, stronger performance, greater range and longer battery life for e-mobility and stationary applications. Within electric vehicles, there’s an energy ecosystem that needs improvement to make electric vehicles a more viable choice for everyone too. Under the fusion-powered grow lights, hydroponically grown strawberries or lettuce or other crops can be grown to maturity without the use of pesticides and other harsh chemicals. Reshoring manufacturing from Asia and overseas to the US already cuts down on emissions both from shipping and production (for example, Chinese factories often rely on coal-fired power plants).

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.
It helps increase public confidence in advanced energy solutions, technology readiness, demand and business cases while enabling collaborations and informing policy. Platforms like the Forum’s Advanced Energy Solutions community can help speed up this cooperation and accelerate the deployment of new technologies from decades to years, such as clean fuels and hydrogen, advanced nuclear, storage and carbon removal. The Fostering Effective Energy Transition 2024 report showed that after a decade of progress, the global energy transition has plateaued amid the global energy crisis and geopolitical volatilities. How is the World Economic Forum facilitating the transition to clean energy? 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.
South Korean nuclear fusion reactor sets new record
While nuclear fusion is often dubbed as the holy grail of energy, it is also in the early stages of realization. Advanced nuclear technologies range from fusion and small modular reactors (SMRs) to nuclear fuels and waste management, and they can help address some of the concerns around safety and cost. As energy demand is projected to increase, particularly the demand for 24/7 clean power, nuclear energy is undergoing a renaissance as countries and industries realize that renewable sources alone won’t be able to meet this demand. “Our laser was not built for energy generation, it was built as a backbone of a national security programme. If we want to take this forward, public-private partnerships are going to be essential. If I look at the private-sector fusion companies that have already been spun out, they have needs for expertise and certain specific skills that it would be cost prohibitive to develop within a start-up framework. So they can partner with the laboratories to get access to that capability and expertise. In the inertial confinement fusion space, it’s essential. “It cost about $3.5 billion to build the facility and we spend about $350 million a year running it. It was a leading edge, high-risk project when we began to build the laser. Seven of the 10 critical technologies did not exist, they had to be created along the way. This is what public-sector investment is good at, large-scale, able to manage risk over time and bring resources to bear at the laboratory from a wide range of disciplines.
It’ll take years to get there, but at fusion’s fullest capacity, anyone will be able to use as much electricity as they need, with no environmental costs and very little expense. We are working to shepherd fusion energy’s leap from experimental laboratories to grid-ready power plants in the 2030s. That’s a huge step forward for the decades-long global mission of fusion scientists, providing humanity with a cheap, limitless and carbon-free source of electricity. In the Sun, massive gravitational forces create the right conditions for nuclear fusion in the star’s core, but on Earth, they are much harder to achieve. Emissions-free nuclear fusion technology could be a game-changer in the fight against climate change, if it can be scaled up.
The technology still needs to overcome the common misconception that heat pumps can’t hack it anywhere that experiences true winter. Despite doing all the work of central heating and cooling, heat pumps use far less energy than an oil burner or HVAC systems. By harnessing the energy in the outside air, which is present even on cold days, and moving it inside in the form of heat, heat pumps can efficiently warm a home. Nuclear fusion, however, was not a major part of the conversation — but as the drought and heat waves in Europe, the flooding in Pakistan and Nigeria and every other climate catastrophe has recently shown, we need large-scale changes. Nuclear fusion reactors around the world are being built to find the best way to control and capture the energy of such reactions. As people seek out cheap ways to keep warm this winter, it is clear that we need long-term investment in cost-competitive, stable and clean energy.
MPP is an initiative created by the World Economic Forum and the Energy Transitions Commission. Benchmarking progress is essential to a successful transition. In 2018 energy intensity improved by 1.2%, the slowest rate since 2010. What comes after could look like the space race, but this time we won’t need seven decades to reach our moon. Commonwealth Fusion Systems will turn on a demonstration power plant, called SPARC, in 2027.
