Spring-headquartered ExxonMobil Corp. has announced a new MOU for an offtake agreement for up to 100,000 metric tons of lithium carbonate.

The agreement is with LG Chem, which is building its cathode plant in Tennessee and expects it to be the largest of its kind in the country. The project broke ground a year ago and expects an annual production capacity of 60,000 tons. The lithium will be supplied by ExxonMobil.

“America needs secure domestic supply of critical minerals like lithium,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release. “ExxonMobil is proud to lead the way in establishing domestic lithium production, creating jobs, driving economic growth, and enhancing energy security here in the United States.”

The industry currently has a lithium supply shortage due to the material's use in electric vehicle batteries and the fact that most of production happens overseas.

“Building a lithium supply chain with ExxonMobil, one of the world’s largest energy companies, holds great significance,” Shin Hak-cheol, CEO of LG Chem, adds. “We will continue to strengthen LG Chem’s competitiveness in the global supply chain for critical minerals.”

Per the release, the final investment decision is still pending.

Earlier this year, Exxon entered into another energy transition partnership, teaming up with Japan’s Mitsubishi to potentially produce low-carbon ammonia and nearly carbon-free hydrogen at ExxonMobil’s facility in Baytown.

Last month, the company announced it had signed the biggest offshore carbon dioxide storage lease in the U.S. ExxonMobil says the more than 271,000-acre site, being leased from the Texas General Land Office, complements the onshore CO2 storage portfolio that it’s assembling.

ExxonMobil signs biggest offshore CCS lease in the U.S.

big deal

Spring-based ExxonMobil continues to ramp up its carbon capture and storage business with a new offshore lease and a new CCS customer.

On October 10, ExxonMobil announced it had signed the biggest offshore carbon dioxide storage lease in the U.S. ExxonMobil says the more than 271,000-acre site, being leased from the Texas General Land Office, complements the onshore CO2 storage portfolio that it’s assembling.

“This is yet another sign of our commitment to CCS and the strides we’ve been able to make,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The offshore site is adjacent to a CO2 pipeline network that ExxonMobil acquired in 2023 with its $4.9 billion purchase of Plano-based Denbury Resources.

Ammann told Forbes that when it comes to available acreage in the Gulf Coast, this site is “the largest and most attractive from a geological point of view.”

The initial customer for the newly purchased site will be Northbrook, Illinois-based CF Industries, Forbes reported.

This summer, ExxonMobil sealed a deal to remove up to 500,000 metric tons of CO2 each year from CF’s nitrogen plant in Yazoo City, Mississippi. CF has earmarked about $100 million to build a CO2 dehydration and compression unit at the plant.

A couple of days before the lease announcement, Ammann said in a LinkedIn post that ExxonMobil had agreed to transport and annually store up to 1.2 metric tons of CO2 from the $1.6 billion New Generation Gas Gathering (NG3) pipeline project in Louisiana. Houston-based Momentum Midstream is developing NG3, which will collect and treat natural gas produced in Texas and Louisiana and deliver it to Gulf Coast markets.

This is ExxonMobil’s first CCS deal with a natural gas processor and fifth CCS deal agreement overall. To date, ExxonMobil has contracts in place for storage of up to 6.7 metric tons of CO2 per year.

“I’m proud that even more industries are choosing our #CCS solutions to meet their emissions reduction goals,” Ammann wrote on LinkedIn.

ExxonMobil says it operates the largest CO2 pipeline network in the U.S.

“The most fundamental thing we’re focused on is making sure the CO2 is stored safely and securely,” Ammann told Forbes in addressing fears that captured CO2 could seep back into the atmosphere.

Houston company scores agreement to work on Canadian green hydrogen project

contract secured

Houston-headquartered McDermott has reported that it secured an agreement to work on Canada's first commercial green hydrogen and ammonia production facility.

The Early Contractor Involvement agreement is from Abraxas Power Corp. to work on the Exploits Valley Renewable Energy Corporation (EVREC) project located in Central Newfoundland and will include developing a wind farm with up to 530 turbines that will have the ability to generate 3.5 gigawatts of electricity and 150 megawatts solar photo voltaic. Additionally, the facility, once completed, will be able to produce 165 kilo tons per Annum of hydrogen and 5,000 metric tons per day of ammonia.

"The agreement is testament to McDermott's industry-leading delivery and installation expertise, and the breadth of our capabilities across the energy transition," Rob Shaul, McDermott's senior vice president, Low Carbon Solutions, says in a news release. "Our century of experience, from concept to completion, and integrated delivery model, means we can offer Abraxas a repeatable modular implementation solution that is expected to drive cost savings, reduce risk and provide quality assurance."

Per the agreement, the company will provide front-end engineering design, engineering, procurement, and construction execution planning services, and more for the project. According to McDermott, the company's contribution to the project will be led from McDermott's Houston office with support from its office in India.

Recently, another collaboration McDermott is working on reached a new milestone. Houston-based Element Fuels has completed the pre-construction phase of its hydrogen-powered clean fuels refinery and combined-cycle power plant in the Port of Brownsville. McDermott is providing front-end engineering design services for the project.

In October, McDermott announced that it signed a lighthouse agreement with United Kingdom-based industrial software company AVEVA and Massachusetts-based product lifecycle management platform provider Aras. With the new software, McDermott plans "to develop its asset lifecycle management capability across the energy transition, oil and gas, and nuclear sectors," per the news release.

ExxonMobil breaks ground on Texas carbon dioxide storage project

digging in

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.

Equinor buys into massive CCS joint venture project near Houston

M&A Moves

A Norwegian energy company with its United States headquarters in Houston has announced it has acquired a significant chunk of a carbon capture and storage joint venture.

Equinor now owns a 25 percent interest in Bayou Bend CCS LLC, which is reported to be one of the largest domestic carbon capture and storage projects. The project — a JV between Chevron, Talos Energy Inc., and now Equinor, is located along the Gulf Coast in southeast Texas. The terms of the deal were not disclosed.

“Commercial CCS solutions are critical for hard-to-abate industries to meet their climate ambitions while maintaining their activity," Grete Tveit, senior vice president for Low Carbon Solutions in Equinor, says in a news release. "Entering Bayou Bend strengthens our low carbon solutions portfolio and supports our ambition to mature and develop 15-30 million tonnes of equity CO2 transport and storage capacity per year by 2035. Our experience from developing carbon storage projects can help advance decarbonization efforts in one of the largest industrial corridors in the US."

According to Equinor, it purchased its share through the acquisition of Carbonvert's subsidiary, Texas Carbon 1 LLC. Chevron, the operator, holds 50 percent interest, and Talos holds the other 25 percent interest.

“We look forward to working together with our partners to further mature this exciting project. Bayou Bend is Equinor’s first announced low carbon solutions project on the Gulf Coast. Alongside our upstream production and offshore wind developments, we’re strengthening our position as a broad energy company and expanding our footprint in the Gulf region,” Chris Golden, senior vice president and US Country Manager, says in the release. "Bayou Bend is a significant milestone towards growing our low carbon portfolio in the US.”

With about 140,000 gross acres of pore space for permanent CO2 sequestration and over one billion metric tons of gross potential storage resources, according to the release, Bayou Bend is positioned to be one of the largest CCS solutions in the US for industrial emitters.The project spans around 100,000 gross acres across Chambers and Jefferson Counties in southeast Texas, and approximately 40,000 gross acres offshore Beaumont and Port Arthur.

“Delivering lower carbon solutions to harder-to-abate industries is fundamental to Chevron New Energies’ mission, and as a Southeast Texas native, I know how vital these industries are to our local communities and their economies,” Chris Powers, vice president of CCUS at Chevron New Energies, in the release. “We thank Carbonvert for its work on the project, and we look forward to Equinor bringing its expertise and resources to Bayou Bend as it joins the partnership.”

Each of the company's low-carbon innovation arms — Low Carbon Solutions at Equinor, Chevron New Energies division, and Talos Low Carbon Solutions division — are collaborating on the project.

“We continue to make significant progress in developing Bayou Bend, which we believe will be a premier regional carbon storage hub solution for Texas’ largest industrial region. Equinor is a welcomed addition to the partnership. Their experience and track record further enhance the joint venture, which is committed to developing safe, reliable, cost-effective lower carbon solutions while enabling continued economic growth,” said Robin Fielder, executive vice president – Low Carbon Strategy and Chief Sustainability Officer of Talos.

In 2021, Texas General Land Office in Jefferson County, Texas, selected Talos and Carbonvert for the carbon storage lease, located in state waters offshore Beaumont and Port Arthur, Texas. Chevron joined the JV in May 2022. The project expanded earlier this year.

The project is located in southeast Texas, about 70 miles outside of Houston. Image via equinor.com

Houston’s data center capacity set to grow 80%, report says

data findings

Houston stands to benefit from constraints dogging data center markets elsewhere in Texas, a new report indicates. This comes against the backdrop of Texas surpassing Virginia as the country’s top state for data centers — and amid deepening opposition to these facilities.

The report, published by commercial real estate services provider JLL, foresees Houston continuing to gain traction in data center development as occupants seek “scalable alternatives” to Texas markets experiencing supply-and-demand imbalances.

The Houston area currently hosts data centers with 287 megawatts of capacity, well below capacity levels in the Dallas-Fort Worth, Austin-San Antonio and West Texas markets.

However, the region is witnessing a spike in capacity, with 390 megawatts of capacity under construction, according to the report. Counting newly built data centers, Houston would be home to 677 megawatts of data center capacity, an 80 percent increase from the current inventory, the report says.

Developers target West Houston for large-scale data centers

Developers increasingly are evaluating West Houston and surrounding areas for large-scale campuses capable of supporting behind-the-meter power, according to the report. Data center development in the region is likely to remain concentrated in those areas, where power is readily accessible and flood risks are lower, the report adds.

The report notes that Houston is evolving from a traditionally enterprise-focused co-location market for data centers into a “credible large-scale growth market,” buoyed by rising interest in hyperscale facilities and increased development activity.

Corporate, energy and healthcare users are still active in Houston’s data center market, the report says, with cloud computing and technology tenants making inroads. The Houston market absorbed 25 megawatts of data center capacity in the first half of this year.

Texas crowned No. 1 state market for data center capacity

The growth of Houston’s data center sector is occurring in tandem with Texas’ ascent as a data center market. The report shows Texas now boasts 26 gigawatts of existing and under-construction capacity, followed by Virginia at 13 gigawatts.

JLL declares that “Texas has cemented its position as the state for data centers.”

The “frontier” markets of West Texas, the Carolinas, Louisiana, and Ohio account for 77 percent of all capacity being developed nationwide, according to the report.

As evidence of Texas’ heightened stature in the data center sector, commercial real estate services provider Cushman & Wakefield recently ranked Dallas as the world’s No. 1 primary data center market, while Austin-San Antonio led the list of second-tier markets and West Texas topped the third-tier ranking.

These rankings underscore “Texas’ growing importance as a large-scale AI infrastructure hub,” Cushman & Wakefield says.

Opposition to new data centers in Texas grows

While businesses see the value of adding data centers in Texas, the state’s data center boom is rattling residents and politicians alike.

A recent University of Houston survey finds that although 85 percent of Houston-area residents use AI—a key driver of data center growth—nearly 63 percent oppose construction of a data center within a mile of their home. Experts estimate 6.5 gigawatts of capacity, or roughly one-fifth of the total U.S. pipeline, will join the Texas power grid by 2030, with Houston serving as a main hub.

A poll taken recently by the University of Texas/Texas Politics Project yielded similar results: 56 percent of Texans oppose development of data centers in their community.

“Texas’ grid is already facing pressure from population growth, extreme weather and rising industrial demand,” UH researcher Soran Mohtadi says. “When residents say they are concerned about data centers, they’re mostly referring to grid reliability and affordability.”

Data center backlash prompts action by politicians

Responding to Texans’ concerns over power and water consumption, Gov. Greg Abbott recently imposed a moratorium on new data centers in the state to allow time for regulatory agencies to assess the projects’ impact. Meanwhile, some state lawmakers are calling for a crackdown on data center development.

Last month, a state legislative committee chaired by Sen. Joan Huffman, a Houston Republican, held a hearing on the effects of state sales tax exemptions given to data centers. The cost of these exemptions has climbed from an estimated $14.6 million in 2014-15 to a projected $3.3 billion in 2028-29, according to law firm Holland & Knight.

Two backers of massive data centers in Texas, social media giant Meta Platforms and AI powerhouse OpenAI, agreed this week to comply with Abbott’s recently issued standards regarding data center projects—and more have followed suit.

Dan Diorio, executive vice president of state policy and government affairs for the industry-backed Data Center Coalition, fears backlash against data centers may curb economic growth in Texas.

“I worry that communities that put moratoriums ultimately create too much uncertainty and unpredictability, and what that ultimately means is that those communities may shut themselves off to data center development but also may shut themselves off to broader economic development,” Diorio told Fox 7 News in Austin.
