North Sea CO2 storage leads global efforts with advanced US projects underway

During a recent Senate Conservation meeting, New Mexico legislators discussed the growing importance of carbon dioxide (CO2) storage technology as a critical component in addressing climate change. The meeting highlighted the advancements in CO2 storage projects, particularly in the United States, where 276 projects are currently in development, with 19 already operational.

The discussion emphasized the significant progress made in CO2 storage, particularly in the Permian Basin, which is responsible for storing millions of tons of CO2 annually. In 2023 alone, the U.S. stored approximately 6.75 million tons of CO2, with a majority of this occurring in New Mexico and West Texas. Experts noted that the technology for capturing and storing CO2 is mature and readily available, with a notable increase in direct air capture (DAC) companies from three to over 4,000 in just four years.

Legislators expressed concerns regarding the long-term impacts of CO2 storage, particularly the chemical reactions that occur when CO2 is injected underground. Experts reassured attendees that extensive studies have shown that CO2 behaves predictably when stored, initially dissolving in water and eventually transforming into solid rock over time, making the process safer as it matures.

Despite the promising developments, some legislators voiced skepticism about the reliance on CO2 storage as a solution to climate change. They stressed the need for a balanced approach that includes reducing emissions alongside technological advancements. The meeting concluded with a call for continued regulatory support to foster the growth of CO2 storage initiatives, underscoring their potential role in mitigating climate change impacts in New Mexico and beyond.
