Google invests in a US gas-powered plant that captures carbon dioxide for Midwest data centres

Google announced on Thursday that it had entered into the nation's first corporate agreement for the purchase of electricity from a U.S. plant that uses carbon capture and storage. The deal is to fuel the company's data centers located in the Midwest. Big Tech's plans for expanding technologies such as generative artificial intelligence that will require huge amounts of electricity have clashed with the reality of a U.S. grid that is running out of supplies.

In recent months, companies such as Google have made a number of announcements to fund the construction of new and expanded plants in the United States. Google has recently made deals to purchase electricity from advanced nuclear power plants, geothermal energy and hydropower. Google is working with PJM Interconnection - the largest U.S. grid that covers the world's biggest concentration of data centres - to accelerate the connection of power sources.

Google's latest agreement to purchase power involves a 400 megawatt power plant being built in Decatur, Illinois by Low Carbon Infrastructure, a privately owned company. In the early 2030s, it is anticipated that power will be produced using carbon capture. This involves trapping around 90% of CO2 emission and injecting it underground. Google has not disclosed the financial terms of this deal. Low Carbon Infrastructure stated that the project financing is expected to reach a final investment decision by the first half 2026.

Michael Terrell, Google's head of Advanced Energy, explained that the concept of natural gas-fired electricity, which captures and stores carbon dioxide, had been absent from the equation.

Terrell stated, "We have been focusing on developing all these new clean technologies that are available 24/7. This is a very important piece of the puzzle." It's an important technology the world needs. The Broadwing project is being built on an industrial site owned by Archer Daniels Midland, a company that has been injecting carbon dioxide into the ground from ethanol production.

Jonathan Wiens is the CEO of Low Carbon Infrastructure. He said, "Broadwing shows that carbon capture today can be commercially feasible." The companies say that the construction is expected to take four years, and will create 650 jobs for union workers and 100 positions in construction management and support.

The carbon sequestered on the site will be permanently stored in wells 5,000 to 7,000 feet (1 524-2 2,133 m) below ground. ADM can also purchase electricity from this operation. It will deliver power to the Midcontinent Independent System Operator (MIDSO), which covers 15 Midwest States and multiple Google data centres.

Google and Low Carbon Infrastructure have said that they intend to pursue CCS facilities elsewhere in the U.S. but they did not reveal specific locations or timeframes.

The International Energy Agency (IEA) and the Intergovernmental Panel on Climate Change have promoted carbon capture and storage as a way to reduce emissions in heavy industry and power plants that use fossil fuels. Critics have however questioned the cost, scalability, and long-term efficacy of carbon capture and storage. (Reporting and editing by Marguerita Chy)
