Big Tech Backs Tripling of Global Nuclear Power Capacity by 2050
A group of large energy users, including technology giants Amazon, Google, and Meta, on Wednesday pledged their support to the goal of at least tripling global nuclear capacity by 2050.
The tech firms were among the founding signatories of the pledge as a cross-industry group of eight large energy users teamed up for the first time to launch a cross-sector pledge “to emphasize nuclear energy’s essential role in enhancing energy security, resiliency and providing continuous clean energy.”
The pledge was signed on the sidelines of CERAWeek 2025, the top U.S. energy conference running in Houston this week.
The founding signatories – Amazon, Google, Meta, Dow, Occidental, Allseas, OSGE, and IHI – expect the pledge to gain more support over the coming months, reflecting growing interest in nuclear power from industries including the maritime, aviation, and oil and gas sectors.
The eight companies have come together to publicly back an extensive and concerted expansion of nuclear power to meet increasing global energy demand. They also urge other energy users to support the goal to triple nuclear energy.
With Wednesday’s pledge, the signatories join 14 major global banks and financial institutions, 140 nuclear industry companies, and 31 countries in supporting the goal to triple global nuclear capacity by 2050.
In September 2024, banks including Morgan Stanley, Goldman Sachs, Bank of America, Barclays, and BNP Paribas, recognized the key role that nuclear energy must play in the global energy transition and that improving access to financing can help unlock nuclear energy’s potential.
As energy demand is soaring with the advancements in AI, Big Tech firms are backing the development of next-generation nuclear reactors.
Renewables plus battery storage cannot meet all the growth in demand, so nuclear power has become the next best thing for Big Tech, which is looking to boost AI advancements and climate commitments at the same time.

The announcement, at CERAWeek 2025 in Houston, Texas, in the USA, of the Large Energy Users Pledge, follows earlier pledges by 31 countries, by 140 nuclear industry companies and 14 major global banks and financial institutions to support the tripling goal.
The pledge says that "despite ongoing energy efficiency and optimisation efforts, energy demand in many industries is expected to increase significantly in the coming years in order to support growing economies" and the signatories "agree that nuclear energy capacity should at least triple by 2050, from current levels, to help achieve global goals for enhanced energy resiliency and security, and continuous firm clean energy supply".
It recognises "that large energy users often depend on the availability of abundant energy for their successful and cost-competitive operations, and that nuclear energy can provide round-the-clock energy independently of the weather, the season or the geographical location" and that "safe, clean, firm energy technologies, including nuclear, play an important role in creating a diversified and reliable grid".
They also agree "that there is a significant role for nuclear technologies to provide generation for a wide range of economic activity, including the technology sector, increased electrification, the provision of high temperature industrial process heat, hydrogen production, district heating and the production of synthetic fuels" and "by ensuring that nuclear and other energy sources have equal access to finance, governments can enable nuclear capacity deployment at scale worldwide". It also calls "on other large energy user companies to join this pledge".
What the signatories said
Google's Lucia Tian, Head of Clean Energy & Decarbonization Technologies, said: "We are proud to sign a pledge in support of tripling nuclear capacity by 2050, as nuclear power will be pivotal in building a reliable, secure, and sustainable energy future. Google will continue to work alongside our partners to accelerate the commercialisation of advanced nuclear technologies that can provide the around-the-clock clean energy necessary to meet growing electricity demand around the world."
Amazon Web Services' Brandon Oyer, Head of Americas Energy and Water, said: "Accelerating nuclear energy development will be critical to strengthening our nation’s security, meeting future energy demands, and addressing climate change. Amazon supports the World Nuclear Association’s pledge, and is proud to have invested more than USD1 billion over the last year in nuclear energy projects and technologies, which is part of our broader Climate Pledge commitment to be net-zero carbon by 2040."
Meta's Urvi Parekh, Head of Global Energy, said: "As global economies expand, the need for a reliable, clean, and resilient energy supply is paramount. Nuclear energy, with its ability to provide continuous power, can help meet this rising demand. We’re excited to join alongside this multi-organisational effort with the Tripling Nuclear Pledge to reiterate our commitment to nuclear energy."
Dow Energy & Climate Business Vice President Edward Stones said: "Energy is the lifeblood of global manufacturing and therefore investing and expanding access to clean, reliable, cost-competitive nuclear energy is critical to industrial progress. Dow considers nuclear energy, especially the promising technology of advanced small modular nuclear, to be a long-term competitive source of safe, firm and clean energy."
The announcement
The official unveiling of the pledge will take place at a CERAWeek event co-hosted by World Nuclear Association and Urenco on Wednesday evening. Sama Bilbao y León, Director General of World Nuclear Association, said: "The unprecedented support announced today by some of the world’s most influential companies to at least triple global nuclear capacity by 2050 sends a clear signal to accelerate policy, finance and regulatory changes that enable the rapid expansion of nuclear power. The global shift towards more nuclear highlights this is the only way we’ll deliver the abundant firm clean energy required to power growth and innovation in technology, a host of other industries and the entire economy."
Urenco Chief Commercial Officer Laurent Odeh said: "It will be a lot harder to address environmental concerns while facilitating economic development in the world without the reliable, 24/7 baseload power nuclear energy provides. This support from large energy users is another sign for governments to enable new nuclear projects so we can accelerate construction and meet the energy needs of both industry and the public.”
The background
Over the past year there have been a growing number of companies which use large amounts of energy - and expect their needs to increase - who have announced plans to invest in nuclear energy as a way to meet their requirements while also cutting their carbon emissions. The growing energy demands of AI and data centres has led to large numbers of small modular reactor, and some large-scale new nuclear units, being planned or discussed, as well as growing recognition from other industries that they can use nuclear-generated energy and heat to decarbonise their industrial processes.
The initial pledge to triple global nuclear energy capacity was launched by World Nuclear Association in partnership with Emirates Nuclear Energy Corporation ahead of the COP28 summit in Dubai in 2023.
Nuclear energy currently accounts for 9% of the world's electricity from 439 operable nuclear power reactors. Global energy demand is projected to grow at about 4% per year, according to the International Energy Agency.
Data4 and Westinghouse to evaluate AP300 for data centre deployment
European data centre developer and operator Data4 is to evaluate the AP300 small modular reactor for deployment at one of its future European data centres under an agreement with Westinghouse Electric Company.
_31352.jpg)
The AP300 - which is based on the Westinghouse AP1000 pressurised water reactor - has been selected by Data4 as its technology of choice in a memorandum of understanding signed by the two companies on 11 March.
Data centre operators need abundant, highly reliable and clean power to operate 24/7, mission-critical digital services. Westinghouse says its AP300 technology meets this critical need by providing cost-effective, carbon-free baseload nuclear power in a safe, compact and flexible design based on the proven Westinghouse AP1000 pressurised water reactor.
The data centre industry is undergoing a profound transformation with the rise of artificial intelligence, Data4 CEO Olivier Micheli said. "In the past, data centres relied solely on traditional power utilities. Today, we are entering an era where the campuses of the future will be powered by multiple intelligent sources, seamlessly integrating on-site generation, traditional grid supply and energy storage," he said.
"By integrating a solution such as the Westinghouse AP300 SMR, these campuses will gain greater energy autonomy, reducing their reliance on traditional grids and helping to alleviate pressure on public power networks. This marks a major step toward a more resilient, sustainable and self-sufficient data centre infrastructure."
Westinghouse President and CEO Patrick Fragman said small modular reactors offer a promising solution for powering the next generation of energy-intensive computing. "Our AP300 modular reactor can provide data centres with a dedicated, on-site power source for reliable and carbon-free energy," he added.
Westinghouse claims its 300 MWe reactor design is the most proven and readily deployable small modular reactor solution, without the first-of-a-kind risks associated with other designs that are under development, because it uses AP1000 engineering, licensing, components and supply chain. The company says it expects the AP300 to be in operation by the early 2030s.
Data4 finances, designs, builds and operates its own data centres. Its 35 European data centres in France, Italy, Spain, Poland, Germany and Greece are grouped together on campuses, a model the company says offers an efficient and scalable solution for its customers.

The United States is experiencing renewed bipartisan support for nuclear energy, with recent legislation and investments aimed at expanding its role in the global market.
A global nuclear energy renaissance driven by increased energy demands and climate change goals presents an opportunity for the US to challenge Russia's significant influence in the sector.
The US government and private sector, including tech giants, are actively working to develop and deploy advanced nuclear technologies to ensure energy security and reduce reliance on Russian nuclear energy sources.
In a time of extreme contention and relentless flux in United States politics, at least one thing appears to be a consistent bipartisan priority: defending the nation’s position as the world’s premier nuclear energy producer and expanding the nation’s presence in the global nuclear energy marketplace.
Nuclear energy is currently undergoing an international renaissance as energy demand continues to balloon and decarbonization goalposts draw nearer. As developing countries continue to electrify and expand their economies in the climate change era, baseload clean energy is an increasingly enticing option. And now energy demand in developed economies, too, is skyrocketing thanks to runaway energy demand from data centers, propelled in large part by the rapid expansion of energy-intensive Artificial Intelligence.
“The market, technology and policy foundations are in place for a new era of growth in nuclear energy over the coming decades,” the International Energy Agency (IEA) wrote in a report published in January. The IEA says that the world will produce more nuclear energy in 2025 than ever before. In addition, Birol stated that “more than 70 gigawatts of new nuclear capacity is under construction globally, one of the highest levels in the last 30 years, and more than 40 countries around the world have plans to expand nuclear’s role in their energy systems.”
While the United States is still the largest nuclear energy producer in the world, accounting for nearly a third of global capacity, the sector has been underfunded to the point of neglect in recent decades, as nuclear fell out of favor. Now, the U.S. aging nuclear fleet is in decline, with no new reactors currently under construction.
But public and private support for nuclear energy are at their highest point in a decade, and politicians on both sides of the aisle are clearly eager to retain the United States’ dominance in the sector. During Trump’s first administration, the Nuclear Energy Innovation and Modernization Act became law in 2019, facilitating a more advanced reactor licensing process. At the end of 2023, the United States was one of more than 20 countries that cooperated to launch the Declaration to Triple Nuclear Energy at the COP28 global climate conference. Then, in June of 2024, Congress passed the ADVANCE Act in a bipartisan landslide to increase the number of nuclear reactors coming online. And a few months later, Late last year, tech giants Google, Amazon, and Microsoft publicly pledged to invest in small reactors, an emerging technology that could provide cheaper, safer, and more reliable nuclear energy expansion.
And so far, the new Trump administration remains committed to the cause under its current term. Just last month, U.S. Secretary of Energy Chris Wright said that the Trump administration intends to “lead the commercialization of affordable and abundant nuclear energy” in the interest of energy security.
And while the Trump administration is no enemy of Vladmir Putin, expanding U.S. influence in global nuclear energy markets would also serve to counteract Russian geopolitical leverage. The Atlantic Council recently urged that “In partnership with allies, the United States should advance financial and commercial solutions to help countries dependent on Russian nuclear energy diversify their domestic power programs,” before going on to emphasize that “the United States is well positioned to do so.”
The global nuclear energy renaissance has been a major boon to the Russian economy, as the nation’s state-operated nuclear energy firm Rosatom is a giant in international nuclear energy supply chains. Nearly one in five nuclear power plants worldwide are either in Russia or are Russian-built, and any other nation building a nuclear power plant likely has to go through Rosatom for at least some part of the process. Rosatom is a key player in markets for nuclear fuel, enrichment services, and providing lines of funding for new nuclear facilities, which are prohibitively expensive for practically any private company.
The nuclear energy sector has not only shielded the Russian economy from broader energy sanctions, it has also granted the Kremlin significant geopolitical leverage. But years of strong pro-nuclear policy in the United States, as well as demonstrated support from the private sector and especially Silicon Valley, have given the United States the opportunity to exert its own influence in the sector. Moreover, Trump’s “embrace of financial vehicles” to bridge public and private sectors could help fund new nuclear projects, which tend to carry monumentally expensive up-front costs.
Together, the Atlantic Council argues, “these factors bode well for the United States to substantially weaken Russia’s share of global nuclear markets and its geopolitical influence.”

Minister updates parliament on Indian SMR project
The first two lead units of a 55 MW variant of the Bharat small modular reactor will be built at a Department of Atomic Energy site by 2033, Minister of State Jitendra Singh has told parliamentarians.
_68796.jpg)
Singh provided information on the status of the Department of Atomic Energy's (DAE) Bharat small modular reactor (SMR) offering in a written answer to the Lok Sabha, the lower house of the Indian parliament, providing information on the 200 MW version - the BSMR-200 - and a 55 MW version.
The BSMR-200 pressurised heavy water reactor (PHWR) will use slightly enriched uranium fuel, Singh said, adding that the "majority of equipment are within the capability of Indian industries" - India has built 220 MWe PHWRs since the 1980s, and is now constructing a fleet of indigenously designed 700 MWe PHWRs.
The reactor is being designed and developed by Bhabha Atomic Research Centre and Nuclear Power Corporation of India Limited (NPCIL) to provide "captive" power generation for energy intensive industries such as steel, aluminium and cement; for repurposing retiring thermal power plants; and to provide electricity to remote locations without grid connectivity, Singh said.
"The lead unit will be located at a DAE site. The subsequent units are to be located at the sites of the end-user industry in case of captive power plants and at brownfields sites of retiring thermal power plants," he said.
"Manufacturing and delivery of equipment and components will be carried out through various indigenous nuclear vendors developed by DAE. Development of critical items such as low alloy steel forgings required for manufacturing the reactor pressure vessel and reactivity control drive mechanisms have been realised by the domestic private vendors. Development works for other critical items such as reactor coolant pumps have been initiated with the private vendors. All major development works will be completed in the pre-project phase. The concept design of BSMR has been completed and is in approval stage. Estimated time for construction of BSMR is 60 to 72 months after receipt of project sanction."
The BSMR will have passive safety features as well as "several engineered safety systems to ensure nuclear safety during accidents", Singh said. Used fuel will be handled and stored in-situ, in line with India's broad philosophy to recover "useful radioisotopes" by reprocessing, with remaining waste vitrified and stored in engineered facilities in line with internationally accepted practices. "However, in the case of SMRs the reprocessing technology is to be re-engineered based on the fuel configuration," he said.
The 2025 budget includes an allocation of INR20,000 crore (around USD2.5 billion) for the design and deployment of SMRs, Singh noted (1 crore is 10 million).
Deployment plans
A 55 MWe SMR - targeted at deployment in remote locations - is also being developed, Singh said, with the lead twin units to be "set up in a DAE site by 2033".
"Depending on the projected demand, BSMR-200 also can be deployed for such purposes. Both these plants are designed to operate in isolated mode not connected to the grid," he said.
New funding to advance Thorizon molten salt reactor development
Thorizon of the Netherlands announced it has secured EUR20 million (USD22 million) in funding to accelerate the development of its advanced small modular molten salt reactor, Thorizon One. It said the funding will be used to advance prototyping, licensing and demonstration of Thorizon One's cartridge fuel system.
_176032_38177.jpg)
The company said the latest funding includes EUR16 million as the first tranche of its Series A round, led by the Dutch National Promotional Institution, Invest-NL, backed by an InvestEU guarantee from the European Commission for the research part, with strong backing from Positron Ventures, PDENH, and Impuls Zeeland. It said all of Thorizon's existing shareholders have reinforced their commitment in this investment round.
Thorizon recently secured an additional EUR4 million grant from the Dutch Province of Noord-Brabant in consortium with VDL Groep and Demcon. The recent investments follow an earlier EUR10 million grant from the France 2030 Innovative Reactor Programme of the French government in 2024.
In total, including its first equity round, Thorizon has now raised EUR42.5 million to drive the commercialisation of its reactor technology.
"The capital will drive the prototyping and demonstration of Thorizon One's groundbreaking 'cartridge' fuel system, designed to safely and cost-effectively generate power by recycling nuclear waste," the company said. "Additionally, Thorizon will finalise the reactor's basic design, advance licensing, and prototype key components as it progresses toward starting construction in 2030."
"With strong support from our investors and government partners, we are in a solid position to advance the development of Thorizon One," said Thorizon CEO Kiki Lauwers. "Our mission is to drive nuclear innovation in Europe - enhancing energy security while reducing carbon emissions and burning long-lived nuclear waste. We welcome new strategic partners to join us in making Europe's first molten salt reactor a reality."
Thorizon - a spin-off from NRG, which operates the High Flux Reactor in Petten - is developing a 250 MWt/100 MWe molten salt reactor, targeted at large industrial customers and utilities. The Thorizon One concept is unique in that the core is composed of a set of cartridges that is replaced every five to ten years.
The company said it is conducting pre-feasibility studies at three nuclear-designated sites in France, Belgium and the Netherlands, targeting construction by 2030.
India's Minister of Finance Nirmala Sitharaman announced in the 2024 budget the government's intention to research and develop the Bharat Small Modular Reactor. In this year's budget - announced in February - she promised federal funds to develop at least five Indian-designed SMRs to be operational by 2033, as well as amendments to Indian legislation to encourage private sector participation, as part of plans to develop at least 100 GW of nuclear energy by 2047.
Earlier this year, NPCIL issued a Request for Proposals from 'visionary Indian industries' to finance and build a proposed fleet of 220 MW Bharat Small Reactors. Tata Power and the Naveen Jindal Group have already expressed interest in setting up small modular reactors, and in February, Minister for Railways Ashwini Vaishnaw told the Rajya Sabha - the upper house of the Indian parliament - that nuclear power is under consideration to meet the growing power needs of the country's rail sector.
HD Hyundai to help commercialise TerraPower SMR
TerraPower has announced a strategic collaboration with South Korean conglomerate HD Hyundai to expand the global manufacturing supply chain for Natrium small modular reactors, supporting the rapid commercialisation of the advanced nuclear technology.
_42293.jpg)
The signing ceremony was attended by Chung Kisun, Executive Vice Chairman of HD Hyundai; Won Kwang-shik, Head of Marine Energy Business Division at HD Hyundai Heavy Industries; Bill Gates, founder and chairman of TerraPower; Chris Levesque, president and CEO of TerraPower; and other officials.
The agreement combines HD Hyundai's manufacturing expertise with TerraPower's cutting-edge reactor technology, and will build new supply chain capacity to enable large-scale production and global deployment of Natrium plants.
The agreement with HD Hyundai Heavy Industries - an affiliate of HD Hyundai specialising in shipbuilding - creates the manufacturing foundation necessary for full-scale commercialisation beyond the initial demonstration project that is currently under development. In particular, HD Hyundai will develop optimised manufacturing processes to supply key Natrium reactor components.
This partnership builds upon the relationship established in 2024 when HD Hyundai Heavy Industries was competitively selected by TerraPower to develop the cylindrical reactor vessel to be installed in the first Natrium reactor.
"TerraPower is committed to delivering our first Natrium plant in the United States, as well as rapidly deploying additional units at competitive prices during the next decade in the US and around the world," said TerraPower's Levesque. "The Natrium technology provides crucial baseload power plus gigawatt-scale energy storage; these plants will provide reliable and flexible power to address growing energy demand. HD Hyundai Heavy Industries' manufacturing capabilities are world-renowned, and I look forward to working with them to establish the commercial-scale production capacity that will be essential for successful deployment of multiple Natrium units globally."
Won added: "We expect that HD Hyundai's extensive experience and advanced technological capabilities in manufacturing will help build the foundation for commercialisation of Natrium reactors. Based on this cooperation, we will accelerate the commercialisation of next-generation nuclear energy solutions and create new growth opportunities in the global SMR market."
Natrium technology features a 345 MWe sodium-cooled fast reactor using high-assay low-enriched uranium fuel, with a molten salt-based energy storage system that can boost the system's output to 500 MWe for more than five and a half hours when needed.
TerraPower is the first and only advanced nuclear developer with a permit application for a commercial advanced reactor submitted to the US Nuclear Regulatory Commission. That application was submitted in March 2024 and is on track for approval in December 2026.
TerraPower is constructing the Natrium demonstration plant near a retiring coal facility at Kemmerer in Wyoming. A ground-breaking ceremony held in June last year marked the start of non-nuclear construction at the site. Nuclear construction will begin after the application is approved: the company is eyeing the start of work on the nuclear island in 2026.
Eight RITM reactors currently under production
Russia's Rosatom has begun assembling the RITM-200 reactor vessel for the Leningrad nuclear-powered icebreaker, bringing the total number of RITM reactor units currently being produced at its ZIO-Podolsk plant to eight.

The new generation of Russian nuclear-powered icebreakers - the Project 22220 vessels - each feature two RITM-200 reactors and the ZIO-Podolsk plant, part of Rosatom's machine-building division, has already manufactured 10 of them for the icebreakers Arktika, Sibir, Ural, Yakutia and Chukotka.
The RITM-200 reactors, having demonstrated their suitability for Arctic conditions, are also going to be used in floating power plants which are being built to supply electricity for a large industrial consumer in Chukotka. Another project will use the RITM-200N as part of a land-based small modular reactor nuclear power plant in Yakutia. There is also an agreement for six such reactors in Uzbekistan.
According to Rosatom: "Currently, for the first time in the plant’s history, there are eight RITM series reactor units at different stages of production (for icebreakers and floating power units)."
The nuclear-powered icerbreakers are a key part of Russia's plan to develop the Northern Sea Route, the shipping lane along its north coast, which can cut the distance and speed for shipping goods by sea from northern Europe to Asia.
Plant Director Anton Lebedev said: "We have accumulated a colossal amount of knowledge and skills, and today we have competencies that no one else in the world has, having mastered and launched the flow production of the latest reactor units of the RITM series. This is not only RITM-200 for nuclear icebreakers and small nuclear power, but also their more powerful analogues RITM-400, which will help ensure year-round navigation along the Northern Sea Route."
Background
The Leningrad will be the sixth in the Project 22220 series of icebreakers that are 173 metres long, 34 metres wide and with a height from the waterline to the mainmast of 57 metres. They are designed to break through ice up to three metres thick and have a speed of 22 knots in clear water. The RITM-200 is a pressurised water reactor with a thermal capacity of 175 MW, which converts to 30 MW at the propellers. It is 7.3 metres high with a diameter of 3.3 metres and an integral layout which its manufacturers say means it is lighter, more compact and 25 MW more powerful than previous generations used on nuclear-powered icebreakers. The service life is 40 years.
Rosatom's proposed floating nuclear power plants, with power capacities of 100 MW and 106 MW, have been designed using reactors based on the RITM-200 ones used in the icebreaker fleet. Under a contract signed in 2021, Rosatom's Machine Engineering Division is supplying four floating power units, each with a capacity of up to 106 MW of electric power, for the Baimsky Mining and Processing Plant. Three of the FPUs will be primary units, while the fourth will serve as a backup and the project is designed to be the first "serial" reference for floating power units and the world’s first experience in electrification using a floating power unit for mineral extraction projects.
The nuclear power plant agreement with Uzbekistan is for a six-unit small modular reactor project featuring the 55 MW RITM-200N, adapted from that used in the icebreakers. The Yakutia plant, which was granted a construction licence in April 2023 and which has a commissioning target of 2028, is also due to feature one or two RITM-200N 55 MW reactors, with a service life of 60 years and a five-year refuelling schedule. The proposed RITM-400 is an 80 MW pressurised water reactor and is an option for a 320 MW four-SMR plant in Norilsk.
