“It seems pretty clear to me, I think two years ago, I've got a blog post on this saying that, like, we're going to have to go to solar and batteries for AI data centers at scale and back then everyone was still talking about, like, oh, we're going to build SMRs, you know, and like, well, I love SMRs as much as the next guy.”

The claim, plainly

AI data centers at scale will inevitably rely on solar power and battery storage rather than small modular nuclear reactors.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Casey Handmer's prediction that AI data centers at scale will inevitably rely on solar and battery storage rather than small modular nuclear reactors (SMRs) remains open. The horizon date (2030-10-28) is a default pipeline date rather than a speaker-stated deadline. As of September 2026, operational deployment heavily favors solar and battery storage (over 50 GW of hyperscaler clean energy PPAs contracted, with massive multi-gigawatt battery storage additions in 2025-2026 and 0 GW of operational commercial SMRs for US data centers). However, hyperscalers (including Google, Amazon, and Meta) have signed multi-gigawatt SMR commitments targeting initial commercial operations between 2028 and 2035, while also utilizing conventional nuclear restarts, geothermal, and gas. Whether solar and battery storage permanently outpaces or displaces SMR adoption for hyperscale AI compute will depend on deployment outcomes over the next several years.

As of late August 2026, there are zero fully deployed commercial SMRs operating for data centers in the United States.
Hyperscalers (Google with Kairos Power, Amazon with X-energy, Meta with Oklo) have contracted multi-hundred-megawatt to gigawatt-scale SMR pipelines with commercial operational targets between 2028 and 2035.
Major hyperscalers have contracted over 50 GW of direct clean energy PPAs dominated by solar PV and battery storage by early 2026, with U.S. utility-scale battery storage expanding rapidly.
The IEA projects renewables will supply nearly 50% of additional global data center power demand through 2030, while commercial SMR generation will primarily enter the energy mix after 2030.

Opinion

Mechanical solar tracking systems became economically obsolete in 2016

“Economically speaking we should have deleted trackers in 2016, right? Like the trackers are the systems that move the panels around. Obviously we're still in 2025 installing trackers.”

Handmer: Desalinated water can be produced for $99 per acre-foot

“So I believe that it should be possible to produce water, desalinated water, for 99 bucks an acre foot, which would be transformational, right?”

Handmer predicts China will beat the United States to the Moon

“Relax the outer space treaty in 2017 with the outer space, so the Artemis Accords, so we can go and kind of make a land grab on the moon, and then it turns out China's going to get there first.”

Insight

Synthesizing natural gas from air and water is now financially viable

“The solar has gotten so cheap that you can actually kind of do the reverse process, and it makes financial sense, increasingly so over time.”

Synthetic fuel production is 100 times more land-efficient than biological photosynthesis

“Plants are great. Even this plastic one here but their net throughput efficiency is about a hundred times lower than a synthetic process like the one we're using in terms of like, Area of land into reduced carbon fuel.”
