The race to curb emissions from the AI-driven data center boom is on, and a new study suggests that carbon capture and storage (CCS) could be a game-changer. This technology, which captures carbon dioxide emissions from power plants and stores them underground, might just be the key to managing the climate impact of our growing digital infrastructure.
The study, co-authored by Hon Chung Lau, an adjunct professor at Rice University and founder of Low Carbon Energies LLC, paints a picture of a rapidly expanding data center landscape. By 2030, U.S. data center power capacity is projected to skyrocket from 40 gigawatts in 2025 to a staggering 169 gigawatts. This massive growth in computing power will come with a significant carbon footprint, with emissions rising from 90 million metric tons per year in 2025 to over 404 million metric tons per year by 2030.
What's more, the study highlights the concentration of this growth in specific states like Texas, Virginia, Pennsylvania, Ohio, Arizona, Colorado, Utah, and Illinois. Texas, for instance, is expected to shoulder a massive 25 gigawatts of additional power capacity by 2030 to meet the projected demand.
Here's where CCS steps in as a potential solution. The study finds that natural gas combined cycle power plants equipped with CCS technology could be a practical near-term strategy for providing low-carbon power. Natural gas, being abundant in the U.S., emits less carbon dioxide than coal, and many major data center growth areas are conveniently located near underground saline aquifers, which can be used for long-term carbon storage.
The geology, it seems, is on our side. The study estimates that 34 states have enough saline aquifer storage capacity to handle more than 100 years of projected data center-related carbon dioxide emissions beyond 2030. In 2025, these aquifers could store an estimated 59 million metric tons of data center-related carbon dioxide, and by 2030, that number could grow to 299 million metric tons.
When considering out-of-state storage options, the researchers found that over 90% of data center-related carbon dioxide emissions could potentially be mitigated through CCS. This is a significant finding, as it suggests that the geology and technology exist to make a substantial impact, especially in states where data center growth is most intense.
However, the study also acknowledges its limitations. It only includes data centers with publicly announced power requirements and assumes a constant state energy mix through 2030. Despite these constraints, the results offer a valuable state-by-state framework for balancing digital infrastructure growth with climate goals.
In conclusion, the AI economy's energy demands are immense, and our study helps pinpoint where that demand is headed, where emissions are likely to soar, and where carbon storage could be a lifesaver. As we navigate the challenges of the AI era, carbon capture and storage might just be the key to unlocking a more sustainable future for our digital world.
