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.

Newly Houston-headquartered ExxonMobil acquires carbon capture company in $4.9B deal

M&A Moves

Spring-based energy giant ExxonMobil is making a nearly $5 billion bet on its future in the carbon capture sector.

ExxonMobil announced July 13 that it has agreed to buy Plano-based Denbury, a publicly traded company specializing in carbon capture, utilization, and storage (CCUS), in an all-stock deal valued at $4.9 billion. The deal’s value is based on ExxonMobil’s July 12 closing stock price — $89.45 per share.

Darren Woods, chairman and CEO of ExxonMobil, says the pending acquisition of Denbury “reflects our determination to profitably grow” his company’s low-carbon business unit.

The deal will give ExxonMobil the largest CO2 pipeline network in the U.S. at 1,300 miles, including nearly 925 miles in Texas, Louisiana, and Mississippi, along with 10 onshore carbon sequestration sites.

Dan Ammann, president of ExxonMobil Low Carbon Solutions, says Denbury’s CO2 infrastructure “provides significant opportunities to expand and accelerate ExxonMobil’s low-carbon leadership across our Gulf Coast value chains.”

“Once fully developed and optimized,” Ammann adds, “this combination of assets and capabilities has the potential to profitably reduce emissions by more than 100 million metric tons per year in one of the highest-emitting regions of the U.S.”

ExxonMobil explains that CCUS — when carbon dioxide is captured and stored deep underground instead of being released into the atmosphere — is viewed as critical to meeting net-zero goals. The company forecasts the global market for CCUS will catapult to $4 trillion by 2050. Houston-based consulting firm Rystad Energy predicts total spending on CCUS projects in 2023 will reach $7.4 billion.

In addition to Denbury’s CCUS assets, the deal with ExxonMobil includes Gulf Coast and Rocky Mountain oil and natural gas operations. These assets consist of reserves exceeding the equivalent of 200 million barrels of oil, with 47,000 oil-equivalent barrels per day of current production.

Directors at ExxonMobil and Denbury have unanimously approved the deal, which is expected to close in the fourth quarter of 2023.

Denbury, founded in 1951, posted $1.7 billion in revenue last year, up from 36 percent from 2021.

Chris Kendall, president and CEO of Denbury, launched his oil and gas career at Mobil Oil. Mobil merged with Exxon in 1999 to form the country’s largest oil and gas company, which just made official its headquarters relocation from Irving to Spring.

ExxonMobil generated revenue of nearly $413.7 billion in 2022, making it one of the country’s biggest publicly traded companies.

Engie signs deal to supply wind power for Texas data center

wind deal

Houston-based Engie North America, which specializes in generating low-carbon power, has sealed a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

Under the tentative agreement, Cipher could buy as much as 300 megawatts of clean energy from one of Engie’s wind projects. The financial terms of the deal weren’t disclosed.

Cipher Mining develops and operates large data centers for cryptocurrency mining and high-performance computing.

In November, New York City-based Cipher said it bought a 250-acre site in West Texas for a data center with up to 100 megawatts of capacity. Cipher paid $4.1 million for the property.

“By pairing the data center with renewable energy, this strategic collaboration supports the use of surplus energy during periods of excess generation, while enhancing grid stability and reliability,” Engie said in a news release about the Cipher agreement.

The Engie-Cipher deal comes amid the need for more power in Texas due to several factors. The U.S. Energy Information Administration reported in October that data centers and cryptocurrency mining are driving up demand for power in the Lone Star State. Population growth is also putting pressure on the state’s energy supply.

Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. Also last year, Engie signed a new contract with Meta (Facebook's owner) and expanded its partnership with Google in the U.S. and Belgium.
