Ambrosia Energy to Build 10 GWh Battery Factory in Texas
Ambrosia Energy, a startup founded by two SpaceX alumni, has begun work on a 10 gigawatt-hour battery factory near Austin, Texas, to support off-grid data centers. The factory will enable the company to build about 300 megawatts of power plant capacity per year. The company emerged from stealth in June to provide solar-plus-storage power plants at $100 per megawatt-hour. Its first commercial plant in West Texas, pairing 300 MW of solar with 660 MWh of batteries, will deliver 30 MW of continuous power with 99.3% uptime. The company has been operating a pilot plant for over 100 days and aims to be competitive with natural gas turbines.
While not directly about ad tech, this news is relevant to the infrastructure layer powering AI data centers, which indirectly affects the digital advertising ecosystem. The shift to renewable energy sources for data centers is a significant trend for the industry.

TerraPower Eyes AI Data Centers with Molten-Salt Storage
TerraPower, the Bill Gates–founded nuclear startup, is preparing to announce its first data center project this year, Bloomberg reported. The company is building a 345-megawatt molten salt–cooled Natrium reactor (its first plant is under construction in Wyoming) and says the design includes a large molten sodium thermal storage reservoir. Instead of throttling reactor output, TerraPower plans to store excess heat and release it to meet fast, variable data-center loads, enabling rapid power ramping while keeping the reactor at steady output. The approach is intended to pair nuclear’s high capacity factor with storage flexibility for renewable-heavy grids and AI workloads.
Google Invests $1B in Form Energy's Game-Changing Battery
Google is building a new Minnesota data center that will be powered by wind, solar and a long-duration iron-air battery supplied by startup Form Energy. According to reports, Google paid about $1 billion for the battery system, which can deliver 300 megawatts continuously for 100 hours by oxidizing iron (iron-air chemistry). The battery will help balance output from 1.4 gigawatts of wind and 200 megawatts of solar capacity. Form Energy has built a factory in West Virginia, has raised $1.4 billion to date (per PitchBook), and its CEO Mateo Jaramillo said the company is raising a $500 million round and plans to go public next year.
Google Buys Largest Solar+Battery Project Near xAI Plant
Google announced its largest solar and battery storage purchase to date: the Steel River Energy Center in Arkansas. Google is investing alongside developer Cypress Creek Energy and has contracted the full output of the project's first two phases, which add 1 GW of solar capacity and 1.9 GWh of battery storage. When completed in three phases (final connection scheduled for 2029) the facility is expected to total about 1.8 GW of solar and 2.9 GWh of battery storage; Cypress Creek secured $3.5 billion in financing for the first two phases. The project will feed electricity to the grid to offset Google’s data-center demand and support hourly matching of clean power. The announcement contrasts with xAI’s operation of an unpermitted natural-gas power plant roughly 40 miles south and wider concerns about fossil-fuel use for data centers.
