Amazon, Google make dueling nuclear investments to power data centers with clean energy

Amazon on Wednesday stated that it was investing in small nuclear reactors, coming simply two days after an analogous announcement by Google, as each tech giants search new sources of carbon-free electrical energy to fulfill surging demand from knowledge 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 purchase the facility to provide its knowledge facilities. All three corporations have been investing in photo voltaic and wind applied sciences, which make electrical energy with out producing greenhouse gasoline emissions. Now they are saying they should go additional within the seek for clear electrical energy to fulfill each demand and their very own commitments to chop emissions.

Nuclear vitality is a local weather resolution in that its reactors do not emit the planet-warming greenhouse gases that come from energy vegetation that burn fossil fuels, akin to oil, coal and gasoline. The demand for energy is surging globally as buildings and autos electrify. People used more electricity than ever final yr, inserting pressure on electrical grids around the globe. A lot of the demand additionally comes from knowledge facilities and synthetic intelligence.

The Worldwide Vitality Company forecasts that knowledge 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 Internet Providers’ vice chairman of worldwide knowledge facilities, advised The Related Press, including: “We view advanced new nuclear capacity as really key and essential.”

Vitality Secretary Jennifer Granholm stated she’s thrilled Amazon is the newest to “BYOP” or “bring your own power” to the buildout of knowledge facilities. Granholm spoke at an occasion for Wednesday’s announcement at Amazon’s second headquarters in Virginia. Virginia’s governor and two U.S. senators additionally attended.

America goals to achieve 100% clear electrical energy by 2035. Granholm stated small modular reactors are a “huge piece of how we’re going to solve this puzzle,” a technique to section out fossil gasoline energy whereas responding to the growing electrical energy demand from knowledge facilities and new factories. She stated her division will present $900 million to deploy extra of those reactors.

Small modular reactors are a sort 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 quicker and at a decrease value than giant energy reactors, scaling to suit wants of a selected location. They intention to start out spinning up electrical energy within the early 2030s, if the Nuclear Regulatory Fee offers permission to construct and function their designs and the know-how succeeds.

If new, clear energy is not added as knowledge facilities are developed, the U.S. runs the chance of “browning the grid,” or together with extra energy that is not 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 the moment beneath growth, with none at the moment offering energy to the electrical grid within the U.S. Large traders might help change that, and these bulletins could possibly 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 Know-how, echoed that, saying the trade wants clients who worth the reliability and carbon-free attributes of nuclear and are prepared to pay a premium for it at first, till plenty of the next-generation reactors are deployed and the fee comes down.

On Monday, Google said 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, advised the AP.

With Kairos, Google stated it expects to convey the primary small modular reactor on-line by 2030, with extra to return by means of 2035. The deal is projected to convey 500 megawatts of energy to the grid. For context, Google consumed greater than 24 terawatt hours of electrical energy final yr, in line with 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 present North Anna nuclear energy station in Virginia. It is 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 probably solely a small fraction of the corporate’s complete vitality consumption, a determine that Amazon doesn’t report publicly.

New reactor designs pair effectively with industrial functions as a result of they are often constructed on a small footprint and generate dependable energy, with some capable of present high-temperature warmth too, on the website, stated Doug True, chief nuclear officer on the trade 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 deal with local weather change. By 2030, Google has pledged to fulfill net-zero emissions, and run carbon-free vitality each hour of day by day on each grid the place it operates. It says it has already matched 100% of its international electrical energy consumption with renewable vitality purchases on an annual foundation. Nevertheless, the corporate has fallen short on decreasing its emissions.

Amazon has stated it will match all of its international electrical energy consumption with 100% renewable vitality by 2030, and just lately introduced it met that goal 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 called Scope 1—elevated 7%, in line with its 2023 sustainability report. The corporate can also be focusing on web zero-carbon by 2040.
