ExxonMobil breaks ground on Texas carbon dioxide storage project

ExxonMobil announced this month that it has officially broken ground on a groundbreaking carbon dioxide storage site.

According to a release from the company, a new rig is currently being used to gather information about an underground site in Southeast Texas. The rig stands 225 feet tall, but more importantly extends 8,000 feet below the subsurface to investigate if the site is a safe place to store carbon underground.

“Everyone’s excited about this appraisal well because we’re literally breaking ground on a new chapter of our work to help reduce industrial emissions,” Joe Colletti, who oversees carbon capture and storage development along the Gulf Coast for Exxon, says in a statement.

Exxon plans to move the rig to other sites in the Gulf Coast in the future for clients Nucor Corp., CF Industries and Linde.

In the last year, Exxon has made agreements with these regional companies to store carbon captured from their operations.

  • Exxon agreed to transport and permanently store up to 2.2 million metric tons of carbon dioxide each year from Linde’s hydrogen production facility in Beaumont, Texas when it launches in 2025.
  • Exxon agreed to store up to 2 million metric tons per year of CO2 captured from CF Industries’ ammonia plant in Donaldsonville, Louisiana, starting in 2025.
  • Exxon agreed to capture, transport and store up to 800,000 metric tons per year of CO2 from Nucor’s direct reduced iron manufacturing site in Convent, Louisiana starting in 2026.

Together, the three agreements represent a total of 5 million metric tons per year that Exxon plans to transport and store for third-party customers.

“Our agreement with Nucor is the latest example of how we’re delivering on our mission to help accelerate the world's path to net zero and build a compelling new business,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a statement over the summer. “Momentum is building as customers recognize our ability to solve emission challenges at scale.”

In addition to the carbon storage agreements, the energy giant also completed the acquisition of Denbury Inc. this month in an all-stock transaction valued at $4.9 billion. The deal adds more than 1,300 miles, including nearly 925 miles of CO2 pipelines in Louisiana, Texas and Mississippi to Exxon's CO2 pipeline network.

The deal was first announced this summer.

Dow, a major producer of chemicals and plastics, wants to use next-generation nuclear reactors for clean power and steam at a Texas manufacturing complex instead of natural gas.

Dow's subsidiary, Long Mott Energy, applied Monday to the U.S. Nuclear Regulatory Commission for a construction permit. It said the project with X-energy, an advanced nuclear reactor and fuel company, would nearly eliminate the emissions associated with power and steam generation at its plant in Seadrift, Texas, avoiding roughly 500,000 metric tons of planet-warming greenhouse gas emissions annually.

If built and operated as planned, it would be the first U.S. commercial advanced nuclear power plant for an industrial site, according to the NRC.

For many, nuclear power is emerging as an answer to meet a soaring demand for electricity nationwide, driven by the expansion of data centers and artificial intelligence, manufacturing and electrification, and to stave off the worst effects of a warming planet. However, there are safety and security concerns, the Union of Concerned Scientists cautions. The question of how to store hazardous nuclear waste in the U.S. is unresolved, too.

Dow wants four of X-energy's advanced small modular reactors, the Xe-100. Combined, those could supply up to 320 megawatts of electricity or 800 megawatts of thermal power. X-energy CEO J. Clay Sell said the project would demonstrate how new nuclear technology can meet the massive growth in electricity demand.

The Seadrift manufacturing complex, at about 4,700 acres, has eight production plants owned by Dow and one owned by Braskem. There, Dow makes plastics for a variety of uses including food and beverage packaging and wire and cable insulation, as well as glycols for antifreeze, polyester fabrics and bottles, and oxide derivatives for health and beauty products.

Edward Stones, the business vice president of energy and climate at Dow, said submitting the permit application is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the United States. The project is supported by the Department of Energy’s Advanced Reactor Demonstration Program.

The NRC expects the review to take three years or less. If a permit is issued, construction could begin at the end of this decade, so the reactors would be ready early in the 2030s, as the natural gas-fired equipment is retired.

A total of four applicants have asked the NRC for construction permits for advanced nuclear reactors. The NRC issued a permit to Abilene Christian University for a research reactor and to Kairos Power for one reactor and two reactor test versions of that company's design. It's reviewing an application by Bill Gates and his energy company, TerraPower, to build an advanced reactor in Wyoming.

X-energy is also collaborating with Amazon to bring more than 5 gigawatts of new nuclear power projects online across the United States by 2039, beginning in Washington state. Amazon and other tech giants have committed to using renewable energy to meet the surging demand from data centers and artificial intelligence and address climate change.
