CO₂ stores energy by being “squished” (i.e., compressed) and “released” (i.e., expanded). This enables electricity to be captured when it’s abundant and generated when it’s needed.

The concept behind the “CO2 Battery” is straightforward. Excess renewable energy from the sun and wind is used to compress CO₂ into liquid form. The heat created during compression is saved.

When electricity is needed, the saved heat is used to warm the liquid CO₂ so it expands back into gas form and spins a turboexpander that produces energy to power data centers.

Energy Dome aims to provide electricity-guzzling data centers with round-the-clock renewable energy, even when the sun isn’t shining or the wind isn’t blowing.

It returns about 75% of the energy put in, doesn’t lose performance over 30 years, and can continuously supply electricity for up to 24 hours. More importantly, it’s roughly 50% cheaper than lithium-ion battery farms optimized for utility-scale storage.

He believes AI’s shifting from discovery to diffusion, where the “aha!” moments matter less and the practical applications matter more. In other words, it’s all about how AI can improve society at scale.

This transition mirrors historical patterns across technological advancements. Consider electricity: the initial thrill was generating power, but the real transformation came when it diffused into homes, factories, and warehouses.

Nadella also referenced a famous quote from legendary entrepreneur Steve Jobs: “Computers are like bicycles for the mind.” Just like bicycles amplify a human’s physical ability to travel faster, AI amplifies a human’s mental ability to make decisions faster.

“We’ll evolve from models to systems when it comes to deploying AI for real-world impact,” Nadella added. In other words, companies must develop full systems around multiple models to manage, integrate, and orchestrate AI effectively.

He framed AI as a “socio-technical test”: it challenges society’s willingness to trust it, and that trust is earned through delivering concrete, measurable, and observable outcomes.
