Texas Battery Factory Powers Clean Energy for Data Centers

Former SpaceX engineers just broke ground on a factory that could change how the internet stays online.

Ambrosia Energy is building a 10 gigawatt-hour battery manufacturing plant near Austin, Texas. The facility will produce enough batteries annually to power a 300-megawatt solar energy plant, delivering clean electricity to data centers around the clock.

Co-founders Ben Longmier and Sara Spangelo, who previously sold their satellite company Swarm to SpaceX, spent years searching for the cheapest, fastest way to power data centers off the grid. They landed on a surprisingly simple solution: lots of solar panels during the day, lots of batteries at night.

The 150,000-square-foot factory should reach full production within two to three years. Meanwhile, Ambrosia is already building its first commercial power plant in West Texas later this year.

That plant will pair 300 megawatts of solar panels with 660 megawatt-hours of battery storage to deliver 30 megawatts of continuous power. The team aims for 99.3% uptime, meaning the lights stay on almost all the time.

Here's what makes this exciting: Ambrosia can deliver electricity at $100 per megawatt-hour while still making a profit. That matches the cost of natural gas turbines that big tech companies currently plan to use, but without the carbon emissions.

The secret lies in smart manufacturing. Ambrosia designs its own battery packs and solar mounts with far fewer parts than competitors use. By building components in-house rather than buying from suppliers, they've slashed costs dramatically.

Their custom battery packs cost just 1.3 times the price of bare cells. Industry standard stationary storage systems typically cost five to seven times more than the cells themselves.

The Ripple Effect

A pilot plant has already been running continuously for more than 100 days, generating 200 kilowatts of electricity around the clock. That steady performance proves the concept works in real-world conditions.

As artificial intelligence and cloud computing demand more power, tech companies face a choice between building more fossil fuel plants or finding clean alternatives. Ambrosia's approach shows that renewable energy can match traditional power sources on both cost and reliability.

The data centers powering our daily lives, from streaming videos to video calls with loved ones, could soon run on pure sunshine and smart engineering instead of natural gas.
