Hustler Words – The escalating energy demands of artificial intelligence are propelling major technology firms into an urgent quest for novel power solutions, igniting a fierce competition and a wave of investment into advanced nuclear technologies like fusion and fission. As the world looks towards 2035, the question of what will reliably power our grids remains wide open, with traditional sources facing unprecedented challenges and innovative alternatives rapidly emerging.
Historically, natural gas has served as the default solution for consistent, baseload power due to its established infrastructure, relative affordability, and widespread availability. However, recent geopolitical events, particularly the conflict in the Middle East, have starkly exposed the fragility of its supply chain. Drone strikes targeting critical natural gas infrastructure in Qatar, a significant exporter, underscored this vulnerability. Compounding these issues, a surge in global demand has led to extensive waitlists for gas turbines, with current orders not expected to be fulfilled until the early 2030s. These delays not only imperil the energy security of tech giants but also threaten the long-term dominance of the natural gas industry itself.
In the United States, a substantial 40% of consumed natural gas is dedicated to electricity generation. By the time turbine shortages alleviate, the energy landscape is projected to be teeming with new contenders. Both small modular nuclear reactor (SMR) and fusion power startups are aggressively targeting the next five to seven years for connecting their inaugural commercial power plants to the grid—a timeline remarkably similar to the current lead time for new natural gas power plant components.

The Nuclear Renaissance: Fission’s Edge
SMR startups appear to hold a significant advantage in potentially displacing natural gas. Their technology often refines existing fission reactor designs, leveraging decades of proven fundamental physics. Several companies are pushing for operational reactors before the decade concludes. Kairos Power, with Google as a prospective client, secured approval for its Hermes 2 demonstration reactor in 2024 and is actively constructing it. Oklo, which merged with Sam Altman’s special purpose acquisition company in 2024, aims for commercial operations by 2028.
Other players are close behind. X-energy, backed by Amazon, targets the early 2030s, while TerraPower, founded by Bill Gates and partnered with Meta, plans to commence commercial operations in 2030. For SMRs to truly challenge natural gas, they must achieve rapid scalability and the economies of scale essential to their business models. This is no small feat, yet the confidence of major tech companies is evident through their direct investments and multi-gigawatt power agreements with these startups.
Fusion’s Ambitious Horizon
Nuclear fusion, while less empirically proven than fission, is another technology attracting substantial interest from tech firms. It promises an almost limitless energy supply, utilizing little more than seawater as fuel, with minimal long-lived radioactive waste. Fusion startups are equally ambitious, targeting the early 2030s—or even sooner—for the deployment of their initial reactors.
Commonwealth Fusion Systems, a leading innovator, is on track to activate its demonstration reactor next year, with its first commercial reactor, the 400-megawatt Arc, slated to begin generating power in Virginia in the early 2030s. Inertia Enterprises, a relatively new entrant, intends to commence construction on a grid-scale power plant by 2030, building on the National Ignition Facility’s groundbreaking achievement of net energy gain from controlled fusion.
However, Helion, a startup supported by Sam Altman, boasts perhaps the most aggressive timeline. It is racing to construct Orion, its first commercial-scale power plant, by 2028 to supply Microsoft with electricity. Reports also indicate Helion is in discussions with OpenAI to deliver up to 5 gigawatts by 2030 and an astonishing 50 gigawatts by 2035. Achieving these figures would necessitate building 800 reactors by the end of the decade and an additional 7,200 in the subsequent five years, a scale that would fundamentally reshape the global energy market. To put this into perspective, the U.S. added 63 gigawatts of new generating capacity from all sources last year; Helion alone aims to add nearly 10 gigawatts annually.
The Economic Equation: Cost and Competition
The overarching challenge for all these energy innovators, including traditional gas turbine manufacturers, remains cost. SMR startups are banking on mass manufacturing to drive down expenses, a hypothesis yet to be fully validated. Currently, nuclear power stands as one of the most expensive forms of new generating capacity, estimated at around $170 per megawatt-hour (MWh) by Lazard. Fusion faces similar scaling hurdles, compounded by greater technological unknowns, with initial predictions placing its cost at approximately $150 per MWh.
In contrast, new baseload natural gas power plants typically cost around $107 per MWh, according to Lazard, though prices have been on an upward trend. This trajectory suggests a potential collision course with both new fission and fusion reactors in the coming years.
Yet, a powerful disruptor looms: renewables paired with advanced battery storage. The costs of wind and solar power have plummeted over the last decade. While wind prices have somewhat stabilized, solar continues its downward trend. Battery technology has also become dramatically cheaper, leading to massive grid-scale deployments—58 gigawatt-hours last year alone. Even without subsidies, solar combined with batteries can range from $50 to $130 per MWh, directly competing with and often undercutting fusion, fission, and natural gas.
These figures are based on current battery chemistries primarily designed for electric vehicles. Newer designs, specifically optimized for grid connections, promise even further cost reductions. Form Energy, for instance, recently secured a deal to provide Google with electricity from a 30 gigawatt-hour iron-air battery. Another company, XL Batteries, is developing inexpensive organic fluid batteries that can repurpose old oil tanks for storage, making the battery’s size limited only by available tank capacity. By eschewing critical minerals like lithium, cobalt, and nickel, these next-generation batteries are poised to dramatically reduce the cost of long-duration energy storage, making a compelling case for their widespread adoption and potentially rendering other options less competitive. The race to power the future is not just about technology; it’s increasingly about economics.
