Powering the Future
How Big Tech’s Embrace of Nuclear Energy is Fueling X-energy’s Growth
The growing demand for data centers, fueled by AI advancements, is driving tech companies to seek reliable, sustainable energy sources, with Small Modular Reactors (SMRs) emerging as a promising solution. Companies like X-energy are capitalizing on this shift, positioning themselves at the forefront of the nuclear energy revolution.
The increasing demand for data centers, driven by the rise of artificial intelligence (AI), is reshaping energy strategies for tech giants. As these companies seek reliable, scalable, and carbon-free power sources, nuclear energy—particularly Small Modular Reactors (SMRs)—is becoming an attractive solution. This shift is benefiting companies like X-energy, an Alumni Ventures portfolio company, as they position themselves at the forefront of the nuclear energy renaissance.
What are SMRs, and Why are They Gaining Traction?
Imagine a nuclear reactor small enough to be factory-assembled, transported by truck or boat, and installed virtually anywhere—from industrial sites to remote regions off the grid. These Small Modular Reactors (SMRs), which generate up to 300 MW(e) per unit, are unlocking new possibilities for industries in search of carbon-free energy. With AI-driven data centers and industrial operations demanding stable power sources, SMRs are emerging as a transformative technology.
So, what makes SMRs so exciting?

Enhanced Safety through Passive Systems
When most people hear 'nuclear energy,' safety concerns are often the first thing that come to mind. However, SMRs incorporate passive safety features, relying on natural processes like gravity and convection to prevent accidents without human intervention or external power. This design minimizes the risk of human error and ensures automatic shutdown in emergencies. - Home
Small and Flexible by Design
SMRs take up just a fraction of the space that traditional nuclear power plants need, making them ideal for locations that larger reactors can’t accommodate. Thanks to their modular construction, these reactors can be built and tested in factories, then transported to installation sites—reducing construction time and cost. They are especially well-suited for remote regions or areas with limited access to the power grid. - Home
Faster Deployment and Lower Costs
Traditional nuclear plants are expensive and can take years to complete. SMRs offer lower upfront costs and can be deployed incrementally to match rising energy demand. This flexibility ensures that power infrastructure keeps pace with growth, without the delays and cost overruns often seen in larger, custom-built plants. - Home
A Solution for Remote and Off-Grid Power Needs
Microreactors, a subset of SMRs, produce up to 10 MW(e)—perfect for remote locations or off-grid communities. These reactors can replace diesel generators and provide reliable backup power during emergencies. Their compact size makes them ideal for isolated businesses, small towns, or disaster response efforts, ensuring continuous power without reliance on fossil fuels.
X-energy: A Leader in the SMR Space
X-energy has emerged as a trailblazer in the SMR field, focusing on its innovative Xe-100 reactor and TRISO-X fuel technologies.
- Xe-100 Reactor: A high-temperature, gas-cooled reactor that can scale to 320 MWe using a four-unit configuration, with potential for further expansion. Its compact and road-transportable design makes it easier to deploy than traditional reactors, requiring smaller safety perimeters and reducing operating costs.
- TRISO-X Fuel: X-energy’s advanced fuel is highly robust and can withstand extreme temperatures without melting, ensuring a safer and more efficient energy output.
By combining cutting-edge technology with scalable solutions, X-energy offers cost-effective and carbon-free energy—a perfect match for tech giants looking to power their growing digital infrastructure.
Amazon’s Investment in X-energy: A Game-Changer
Amazon, a global technology leader, has placed a bold bet on nuclear energy with a $500 million investment in X-energy. This funding will support the completion of X-energy’s reactor design, the first phase of its TRISO-X fuel fabrication facility, and help fast-track regulatory approvals.
But Amazon’s involvement goes beyond financing. The company has committed to 5 GW of new nuclear power projects across the U.S. by 2039—the largest commercial deployment target for SMRs to date. Amazon’s need for clean, reliable energy to power its expanding data centers aligns perfectly with X-energy’s capabilities. The partnership’s first project is a 320 MW facility with Energy Northwest in Washington, with options to scale up to 960 MW.
This initiative marks a significant milestone not only for X-energy’s growth but also for Amazon’s net-zero carbon strategy, as the company aims to achieve carbon neutrality by 2040.
X-energy at the Intersection of Technology and Clean Energy
As the worlds of technology and energy converge, the need for scalable, carbon-free power solutions has never been greater. The rise of AI and the increasing energy consumption of data centers are fueling Big Tech’s interest in nuclear power, and X-energy’s SMR technology is perfectly positioned to meet this demand.
Through its innovative reactor designs and strong partnerships with industry leaders like Amazon, X-energy is poised to play a pivotal role in decarbonizing the digital economy. This strategic alignment will not only drive the company’s growth but also contribute to a cleaner, more sustainable energy future.
With SMRs leading the charge, companies like X-energy are transforming the energy landscape—ensuring that the future of technology is powered by reliable, clean, and safe energy. As Big Tech embraces these advanced reactors, X-energy stands at the forefront of the next generation of power.
