Amazon on Wednesday stated that it was investing in small nuclear reactors, coming simply two days after an identical announcement by Google, as each tech giants search new sources of carbon-free electrical energy to satisfy surging demand from information facilities and synthetic intelligence.
The plans come because the proprietor of the shuttered Three Mile Island nuclear energy plant stated final month it plans to restart the reactor so tech large Microsoft should buy the ability to provide its information facilities. All three firms have been investing in photo voltaic and wind applied sciences, which make electrical energy with out producing greenhouse fuel emissions. Now they are saying they should go additional within the seek for clear electrical energy to satisfy each demand and their very own commitments to chop emissions.
Nuclear vitality is a local weather resolution in that its reactors don’t emit the planet-warming greenhouse gases that come from energy vegetation that burn fossil fuels, corresponding to oil, coal and fuel. The demand for energy is surging globally as buildings and automobiles electrify. Folks used extra electrical energy than ever final yr, inserting pressure on electrical grids around the globe. A lot of the demand additionally comes from information facilities and synthetic intelligence.
The Worldwide Vitality Company forecasts that information facilities’ complete electrical energy consumption may attain greater than 1,000 terawatt hours in 2026, greater than doubling from 2022. Estimates counsel one terawatt hour can energy 70,000 houses for a yr.
“AI is driving a significant increase in the amount of data centers and power that are required on the grid,” Kevin Miller, Amazon Net Companies’ vice chairman of world information facilities, informed The Related Press, including: “We view advanced new nuclear capacity as really key and essential.”
America is pursuing small modular reactors, a kind of nuclear reactor that may generate as much as roughly one-third the quantity of energy of a standard reactor. Builders say small reactors might be constructed sooner and at a decrease price than giant energy reactors, scaling to suit wants of a selected location. They purpose to start out spinning up electrical energy within the early 2030s, if the Nuclear Regulatory Fee provides permission to construct and function their designs and the know-how succeeds.
If new, clear energy isn’t added as information facilities are developed, the U.S. runs the chance of “browning the grid,” or together with extra energy that isn’t constructed from clear sources, stated Kathryn Huff, a former U.S. assistant secretary for nuclear vitality who’s now an affiliate professor on the College of Illinois Urbana-Champaign.
The reactors are at present underneath growth, with none at present offering energy to the electrical grid within the U.S. Huge traders can assist change that, and these bulletins may very well be the “inflection point” that makes scaling up this know-how really doable, Huff stated.
Jacopo Buongiorno, professor of nuclear science and engineering on the Massachusetts Institute of Expertise, echoed that, saying the business wants clients who worth the reliability and carbon-free attributes of nuclear and are keen to pay a premium for it at first, till various the next-generation reactors are deployed and the price comes down.
On Monday, Google stated it was signing a contract to buy nuclear vitality from a number of small modular reactors that Kairos Energy, a nuclear know-how firm, plans to develop.
The information highlights “the technologies that we’re going to need to achieve round the clock clean energy, not only for Google but for the world,” Michael Terrell, Google’s senior director of vitality and local weather, informed the AP.
With Kairos, Google stated it expects to carry the primary small modular reactor on-line by 2030, with extra to return by 2035. The deal is projected to carry 500 megawatts of energy to the grid. For context, Google consumed greater than 24 terawatt hours of electrical energy final yr, based on the corporate’s annual environmental report. One terawatt is the same as 1,000,000 megawatts.
In the meantime, Amazon’s bulletins Wednesday included working with utility Dominion Vitality to discover placing a small modular reactor close to its current North Anna nuclear energy station in Virginia. It’s investing in reactor developer X-energy for its early growth work, and collaborating with regional utility Vitality Northwest in central Washington to place 4 of the X-energy reactors there.
Mixed, the three bulletins may account for greater than 5,000 megawatts of energy by the late 2030s with the potential of extra. All of that’s nonetheless possible solely a small fraction of the corporate’s complete vitality consumption, a determine that Amazon doesn’t report publicly.
New reactor designs pair nicely with industrial purposes as a result of they are often constructed on a small footprint and generate dependable energy, with some in a position to present high-temperature warmth too, on the web site, stated Doug True, chief nuclear officer on the business commerce affiliation, Nuclear Vitality Institute.
“It seems like a really good fit to support those facilities, and for a lot of different applications depending upon the amount of power that’s needed by the customer,” he stated.
Each Amazon and Google have dedicated to utilizing renewable vitality to handle local weather change. By 2030, Google has pledged to satisfy net-zero emissions, and run carbon-free vitality each hour of every single day on each grid the place it operates. It says it has already matched 100% of its world electrical energy consumption with renewable vitality purchases on an annual foundation. Nevertheless, the corporate has fallen quick on reducing its emissions.
Amazon has stated it might match all of its world electrical energy consumption with 100% renewable vitality by 2030, and not too long ago introduced it met that purpose early in 2023. Although the corporate has matched its consumption so far as purchases of an equal quantity of renewable vitality, that doesn’t essentially imply it’s utilizing that to energy its operations.
Amazon noticed its electrical energy emissions drop 11%, however direct emissions — often known as Scope 1 — elevated 7%, based on its 2023 sustainability report. The corporate can be concentrating on internet zero-carbon by 2040.
