Google’s Nuclear Energy Deal for AI Power

October 21, 2024

Google announced a groundbreaking agreement to purchase nuclear energy from small modular reactors (SMRs) developed by Kairos Power. This marks the first corporate deal of its kind. The initial SMR is expected to be operational by 2030, contributing 500 MW of carbon-free power to the U.S. electricity grid. Google aims to leverage this energy to support AI technologies and major scientific advances.

Google’s Energy Needs

Google’s shift to nuclear energy stems from its increasing energy demands. Training AI models and maintaining data centers require substantial power. In its 2024 Environmental Report, Google acknowledged a 13% rise in global greenhouse gas emissions in 2023. The company faces challenges in reducing emissions while expanding its technical infrastructure for AI.

Benefits of Nuclear Energy

Google views nuclear energy as a clean and reliable power source. Unlike solar energy, nuclear power can generate energy continuously, making it suitable for round-the-clock operations. The smaller size and modular design of SMRs allow for quicker deployment, aligning with Google’s rapid growth.

Other Corporate Partnerships

Google is not alone in pursuing nuclear energy. Microsoft signed a 20-year agreement with Constellation to develop the Crane Clean Energy Center and restart the Three Mile Island Unit 1, adding approximately 835 MW of carbon-free energy. Amazon has also committed to nuclear energy, partnering with Energy Northwest and investing in SMR technology.

Public Perception of Nuclear Energy

Despite its potential, nuclear energy faces public scepticism. Past accidents, like Chernobyl and Fukushima, have left a lasting negative impression. These incidents involved severe environmental damage and ongoing health concerns. The Three Mile Island accident in 1979, while less catastrophic, still raised alarms about nuclear safety.

Environmental Opposition

Many environmental groups oppose nuclear energy. Friends of the Earth criticises it as one of the dirtiest and most dangerous energy sources. They highlight the risks of accidents, leaks, and the challenges of operating nuclear plants in earthquake-prone areas. Concerns about nuclear waste management and high costs also persist.

Small Modular Reactors (SMRs)

SMRs are seen as a potential solution to some of the issues associated with traditional nuclear power. Their compact designs reduce construction and operational costs. They can be deployed in areas unsuitable for larger plants, making them more versatile. The U.S. Department of Energy has noted their potential to function in regions that cannot support older nuclear facilities.

U.S. Government’s Stance

The U.S. government views nuclear energy as a vital component of its clean energy strategy. The Department of Energy aims to re-establish the U.S. as a leader in nuclear technology amid global competition with China and Russia. Existing nuclear plants in the U.S. prevent nearly 500 million metric tons of carbon dioxide emissions annually, equivalent to removing 100 million cars from the roads.

The future of nuclear energy, particularly through SMRs, remains uncertain but promising. As companies like Google, Microsoft, and Amazon invest in nuclear technology, the landscape of energy production may shift . The balance between public concerns and the need for clean energy will shape the future of nuclear power in the coming years.
