Climate Tech Bets on Space

In space, no one can oppose your data center.

An investment boom is exploding in outer space. Investors have thrown their backing behind space-based solar power, orbital data centers, and even extraterrestrial power grids. SpaceX is pursuing an IPO — potentially the largest the world has ever seen — in part to fund its own off-Earth data center ambitions. The Space Foundation reported that the global space economy reached $613 billion in 2024, combining commercial revenue and government funding, while PricewaterhouseCoopers estimates the sector could grow to reach $2 trillion by 2040, largely driven by private sector innovation and support.

Different though they may be, these technologies all leverage the vast unknown outside our atmosphere to monitor, manage, and optimize terrestrial energy and climate systems.

Current conditions: The French government has recorded at least seven deaths linked to the record early heatwave roasting Western Europe • New York City’s springtime temperature swing is surging upward to about 85 degrees Fahrenheit before dropping back into the 60s later this week • Temperatures in Berbera, the prized Red Sea port city in the de facto independent state of Somaliland, are revving up to 100 degrees today.

1. Trump wants to give weapons-grade plutonium to nuclear startups to use as fuel

The Trump administration is considering handing over leftover weapons-grade plutonium that was set to be buried to companies that aim to use the highly radioactive material as reactor fuel. On Tuesday, the Department of Energy selected five finalists to submit plans to safely transfer the plutonium from a government stockpile. The companies include fuel maker Standard Nuclear, waste reprocessor Exodys Energy, fusion company Shine Technologies, and reactor developers Flibe Energy and Oklo. The move is sure to draw criticism from non-proliferation experts who worry that, unlike the low-enriched uranium used as fuel in conventional reactors, plutonium increases the threat of a rogue actor obtaining material for a bomb. “Countries have tried this before, and they concluded that, as nice as it would be to use that plutonium as fuel, it’s really just a liability and we need to dispose of it permanently,” Scott Roecker, a vice president at the Nuclear Threat Initiative, told The New York Times. In an emailed statement to me, Shine Technologies CEO Greg Piefer said the access to fuel solves “one of the hardest problems in the advanced reactor industry right now.”
