Google announced the next step in its nuclear energy plans 

Google is 1 measurement person to reaching its atomic ambitions present that it’s moving with nationalist powerfulness inferior Tennessee Valley Authority (TVA) to acquisition energy from a next-generation reactor. It’s the archetypal powerfulness acquisition statement for technology this advanced that a US inferior has made, according to the companies. 

The program is for TVA to bargain energy from a reactor being developed by engineering institution Kairos Power successful Oak Ridge, Tennessee. Once the reactor is up and running, expected successful 2030, it should commencement supplying energy to the section grid that serves Google information centers successful Tennessee and Alabama. 

If they negociate to propulsion this each off, it could assistance jumpstart a full caller epoch for atomic vigor successful the US. The nation’s existent fleet of atomic reactors uses decades-old exertion that has struggled to vie with inexpensive energy from gas-fired powerfulness plants and star and upwind farms. Kairos Power is gathering 1 of the archetypal reactors that proponents anticipation tin usher successful a resurgence of atomic energy, and conscionable rising energy request from Big Tech and AI.

The announcement follows quality that Google would acquisition energy from “multiple” small modular reactors designed by Kairos Power. The Hermes 2 objection plant is the archetypal reactor being developed nether that agreement. It expands connected the archetypal Hermes objection reactor that Kairos broke ground connected successful July of past twelvemonth aft receiving the archetypal construction permit from the Nuclear Regulatory Commission for a non-water-cooled reactor successful much than fractional a century. 

Unlike accepted reactors that usage water, Kairos’ exertion uses molten fluoride brackish arsenic a coolant. Since the reactor’s molten brackish coolant has a overmuch higher boiling constituent than water and doesn’t scope a boil, the reactor tin operate astatine comparatively debased pressure. A low-pressure reactor similar Kairos’ exertion is expected to chopped costs for atomic vigor by getting escaped of the request to physique large high-pressure containment structures. 

Oak Ridge, Tennessee — wherever Kairos is gathering Hermes 2 — was erstwhile the office for the Manhattan Project. Now, alternatively of lodging facilities enriching uranium for the archetypal atomic bombs, Oak Ridge has go a hub for atomic vigor projects and research. 

Eventually, Google aims to assistance Kairos deploy 500 megawatts of caller atomic capableness successful the US by 2035. For context, America’s 94 operating atomic reactors had a combined capableness of 97,000MW successful 2024 and accounted for conscionable nether 20 percent of the US energy mix. Hermes 2 is expected to scope a capableness of 50MW. 

Companies that make c pollution-free electricity, similar atomic vigor and renewables, tin marque wealth by selling the energy they supply to the powerfulness grid and by selling alleged clean vigor attributes that are similar abstracted certificates representing the biology benefits of avoiding fossil substance emissions. Google volition person cleanable vigor attributes from the Hermes 2 works done TVA.

Tech companies with clime goals often bargain cleanable vigor attributes to effort to cancel retired the contamination caused by their energy use. By matching its energy usage with those certificates, a institution mightiness assertion that it runs connected cleanable vigor adjacent if it’s plugged into a powerfulness grid that inactive runs connected soiled energy. Extra income from cleanable vigor attributes is expected to assistance developers adhd much c pollution-free powerfulness to the grid (although probe has shown that the environmental benefits are often overestimated). Google’s c emissions roseate again past year arsenic it ramps up its AI offerings.
