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. What will it take for India to lead on deep tech and the global space race? None can be certain of success yet, globally, we must try. Can we get to fusion breakeven in a compact device? Can we get to fusion temperatures in a compact device?
Is the world ready for the transformational power of fusion?
Nuclear fusion gets a lot of public attention due to its fantastic potential. Advanced nuclear technologies can help address some of the concerns around safety and cost. In New York City, heat pumps are becoming common in new developments, and a new programme will start introducing them into the city’s public housing this winter, which has long-standing problems with broken furnaces and inadequate heat. 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.
Fusion mimics the process that powers the sun, creating massive energy without carbon emissions or long-lasting radioactive waste. 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.
Small modular reactors
- But she said the timescale to generating power could be “two or three decades away” and urged great collaboration to build a fusion “ecosystem”.
- 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.
- During the summer, the process can be reversed, moving heat out of the house in order to cool it.
- A nuclear fusion reactor in South Korea has set a new record, superheating a plasma loop to 100 million degrees Celsius for 48 seconds.
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. Commercial fusion energy alone is exciting, but consider the ripple effect of how a shift in energy supply can affect industry and our environment. 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.
CFS is racing against Helion, another US fusion startup backed by OpenAI CEO Sam Altman, which plans to bring a fusion power plant online by 2028 and has signed Microsoft as its first off-take partner. In parallel, governments, utilities and private industry are expanding the fusion ecosystem. A new fusion roadmap published by the US Department of Energy in October outlines how the technology could enter that country’s energy mix by the early 2030s.
While nuclear fusion power offers the prospect of an almost inexhaustible energy source for future generations, it has also presented many so-far-insurmountable scientific and engineering challenges. In May 2023, Microsoft announced a deal with private US nuclear fusion company Helion to buy electricity made using fusion technology in 2028. A concerted effort towards fusion energy is the best way to solve the pressing need to reduce greenhouse gas emissions and ensure the supply of safe, clean energy long into the future. But fusion power can make the prospect of electric heating via heat pumps a zero-emission future.
The challenge is that fusion only happens in stars, where the huge gravitational force creates pressures and temperatures so intense that usually repulsive particles will collide and fuse. Read this piece to explore the industry’s potential. Meanwhile, the space economy is expected to reach $1.8 trillion by 2035 as space-enabled technologies advance. For over half a century, microchips have paved the way for increasingly powerful electronic devices. Sales of electric and plug-in hybrid vehicles increased by 12% in March compared to the same month in 2023, data from Rho Motion shows. 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 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. It only lasted for a fraction of a second, but it proved fusion could be a power source, rather than a power drain. Then, in 2022, Lawrence Livermore National Laboratory in California achieved ‘Lawson’s criterion,’ making the first net-positive energy gain from a controlled fusion reaction.
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 fusion markets review 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.
Pioneering nuclear fusion
Fusion also is the critical driver for enabling exciting artificial intelligence applications powered by energy-hungry data centres. 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.
We have built and demonstrated a tokamak with all its magnets made from HTS and we are now designing the device to get to fusion temperatures. Can we get sufficiently beyond breakeven to produce electricity for the first time? One showed for the first time that it is feasible to build a low power (~100MWe) tokamak with a high power gain. On Earth we need to create similar conditions and hold a hot electrically-charged plasma at high enough pressure for long enough for fusion reactions to occur. Controlled fusion is the ideal long-term energy source, complimentary to renewables. Fusion – with no CO2 emissions, no risk of meltdown and no long-lived radioactive waste – is the obvious solution and has been for decades, but it is so hard to achieve.
In brief: Other tech stories to know
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.
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. One new way we could grow food that would be more environmentally sustainable would be hydroponic vertical farms — if the need for electricity to power the grow lights and other necessary equipment weren’t so high.

Type 1 Diabetes patients in England are to be offered a new technology described as an artificial pancreas. KSTAR is the prototype of the International Thermonuclear Experimental Reactor (ITER) based in France. However, there are still many challenges to overcome before the technology is commercially viable. As the electric vehicle’s story shows, a technological resurgence can take time and may need to demonstrate breakthroughs in adjacent fields – e.g. the electric car brought advances in high-capacity batteries and low-losses electrical engines.
More on energy from the Forum
Nuclear energy produces about 10% of the world’s electricity, according to the International Energy Agency (IEA). In the US — where the heating oil used to fuel furnaces in the northeast is in short supply, and the closure of nuclear plants across the country is leading to skyrocketing electric bills — many are in the midst of a cold and expensive winter. Commercial fusion power generation is expected by some to roll out in the 2030s — which could give the world a seismic final push to meet the UN’s 2050 climate goals, if implemented broadly and quickly. Pioneering inventors, including TAE Technologies in Southern California, are racing to bring this natural process that fuels the sun down to Earth, with terrestrial fusion power plants. While the growth in renewables over the past decade has been promising, nuclear fusion is only beginning to gain the recognition and support required to push it toward commercial use.
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. 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. Brazil is on the way to becoming a ‘nature superpower’, says this expert
With fusion powering the factory (and the logistics infrastructure too), those reductions would be even greater. 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. 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. 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. At the same time, the Forum is also working to support a more integrated approach to energy solutions, including advanced nuclear, clean fuels, hydrogen and carbon removal.
Nuclear fusion, the process that powers the Sun and stars, merges two atomic nuclei into a larger one. Our current nuclear power stations use nuclear fission – essentially splitting an atom’s nucleus. Through its Centres, the World Economic Forum integrates public-private efforts to achieve greater impact. While advancements in AI, quantum computing, biotech, robotics and automation and other fields present numerous opportunities, new technologies are also hiking energy demand. A competitive race and more private investment would be good for the progress of fusion.
