Google is backing green steel for data center construction
The data center boom is also a materials story, and Google is now using its buying power to help scale near-zero-emissions steel.
Original Geekish context based on the source linked below.
The short version
Google says it is partnering with Stegra to support what it calls the world's first large-scale, green hydrogen-based, near-zero-emissions steel plant. The plant is in Boden, Sweden.
How the steel changes
Traditional steelmaking relies on coal to process iron. Google says Stegra's process uses renewable electricity to generate green hydrogen, then reacts that hydrogen with iron ore to produce iron. Stegra estimates the process can cut emissions by up to 95% compared with traditional blast furnace manufacturing.
What Google is buying
Under the agreement, Google will receive environmental attribute certificates from a portion of Stegra's first year of production, tied to up to 91,000 metric tons of steel. Google frames those certificates as a way to create demand for cleaner building materials and help finance early-stage industrial technology.
Geekish take
AI infrastructure is usually discussed in chips, power, and water. Steel belongs in that conversation too, because the physical shell of a data center has its own carbon bill before a single server starts running.
