ExxonMobil, Worley to bring low-carbon hydrogen project to Baytown

big deal

ExxonMobil selected Australia-based engineering and professional services company Worley to provide engineering, procurement and construction services for a proposed hydrogen and ammonia production facility in Baytown, which is expected to have a production capacity of 1 billion cubic feet of blue hydrogen per day. ExxonMobil expects the facility will be the largest of its kind in the world.

“We are delighted to continue our strategic, global relationship with ExxonMobil in its execution of upcoming projects, particularly in delivering this EPC project on the US Gulf Coast, which contributes significantly to strengthening Worley’s backlog,” Chris Ashton, CEO of Worley, states, according to Offshore Energy.

The facility in Baytown is expected to produce 28.3 million cubic meters (1 billion cubic feet) of low-carbon hydrogen daily and nearly 1 million metric tonnes (more than 1 million tons) of ammonia per year, which will also capture more than 98 percent of the associated CO2 emissions.

The facility will leverage advanced carbon capture and storage technologies to reduce emissions associated with hydrogen production. ExxonMobile also said its carbon capture and storage system would be available for use by third-party CO2 emitters in the area.

A final investment decision is expected in 2025 , and an anticipated startup in 2029. “Blue” hydrogen is expected to be a top energy driver in 2025 according to global consultancy Wood Mackenzie who predicts that at least three large-scale blue hydrogen projects in the U.S will reach FID by next year.

The company hopes the new facility will help in creating U.S. jobs and supporting community development initiatives throughout the Houston area, and the state.

Carbon capture and storage

The first full-scale implementation of carbon capture and storage technology at a natural gas combined cycle power plant in the U.S. is coming to Baytown.

Houston power company Calpine announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), which is a carbon capture demonstration facility that aims to capture carbon dioxide from the Baytown Energy Center (BEC). The BEC is a natural gas combined-cycle power plant in Baytown.

The Department of Energy recently announced that it will share in the cost of up to $270 million on the Baytown project. The DOE revealed more details on the project on its website.

The project aims to utilize Shell’s CANSOLV point-source technology to capture up to 2 million metric tons of CO2 per year, which is equivalent to the annual emissions of nearly 450,000 gasoline-powered cars. In addition, the project plans to sequester the CO2 in saline storage sites on the Gulf Coast.

Evaluating the use of greywater cooling to minimize freshwater consumption by reusing wastewater, the project’s primary power and steam off-taker Covestro hopes to prove “technologies that showcase the benefits of decarbonized process heat and electricity in the industrial sector,” according to a news release.

In December of 2023, Calpine was selected by the Department of Energy's Office of Clean Energy Demonstrations for a cost-sharing agreement for a commercial-scale carbon capture and storage project.

"This is a critical step towards decarbonizing Calpine’s facility, which is located on our Covestro Baytown site,” Demetri Zervoudis, Covestro head of operations for North America and Baytown site general manager, said in a previous news release. “Carbon capture and storage technology is an important tool for the chemical industry to reduce carbon emissions, and it is encouraging to see Calpine at the forefront of this transition.”

The Baytown Decarbonization Project was developed collaboratively with local stakeholders in East Houston. According to the company, the project has already incorporated community feedback into the project designs to reduce non-CO2 air pollutants and minimize the usage of freshwater. The company estimates creating 22-26 permanent jobs and 1,500,000 hours of construction jobs and has partnerships with minority-serving institutions.

“Carbon capture is an important technology for decarbonizing the electricity sector and the economy,” Thad Hill, CEO of Calpine Corp said in 2023 when the DOE decided to work with the CSS program. “Calpine is very grateful for the commitment and support for the project by our stakeholders.”

Spring-based energy giant ExxonMobil has enlisted Air Liquide as a partner for what’s being billed as the world’s largest low-carbon hydrogen project.

The deal will enable transportation of ExxonMobil’s low-carbon hydrogen through Air Liquide’s pipeline network. Furthermore, Air Liquide will build and operate four units to supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen each day for the ExxonMobil project.

Air Liquide’s U.S. headquarters is in Houston.

ExxonMobil’s hydrogen production facility is planned for the company’s 3,400-acre Baytown refining and petrochemical complex. The project is expected to produce 1 billion cubic feet of low-carbon hydrogen daily from natural gas and more than 1 million tons of low-carbon ammonia annually while capturing more than 98 percent of the associated carbon emissions.

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The hydrogen project is expected to come online in 2027 or 2028.

ExxonMobil says using hydrogen to fuel its olefins plant at Baytown could reduce sitewide carbon emissions by as much as 30 percent. Meanwhile, the carbon capture and storage (CSUS) component of the project would be capable of storing 10 million metric tons of carbon each year, the company says.
