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.

Houston-headquartered McDermott has received a new contract on a Louisiana clean ammonia project.

Clean energy development company Clean Hydrogen Works tapped McDermott for the front-end engineering and design contract for the Ascension Clean Energy Project. ACE — located in Ascension Parish, Louisiana — is jointly developed by CHW with strategic shareholders ExxonMobil, Mitsui O.S.K. Lines, and Hafnia and is expected to initially produce 2.4 million metric tons per annum of clean ammonia and expand to total 7.2 million metric tons per annum production down the road.

“We are thrilled to partner with McDermott, a company renowned for its extensive experience in mega module construction, demonstrated by a remarkable track record of on-time, on-budget execution of major energy and chemicals projects," Johnny Cook, CHW senior vice president of engineering, procurement, and construction, says in a news release. "This collaboration further strengthens key competitive advantages of our project, including being a mega module capable site with ready infrastructure access to gas, shipping and CCS, an unmatched shareholder base with expertise in CCS and maritime transport, and an experienced team with demonstrated success in executing mega module projects.”

The project has carbon capture and sequestration contracts with ExxonMobil and expects regulatory approvals by early 2025. ACE is expected to reach its final investment decision by late 2025 and start production in 2029. McDermott’s Houston office will lead the project with support from its Gurugram, India, office.

“This FEED award is testament to McDermott’s industry-leading mega-module delivery and installation expertise, and the breadth of our capabilities across the energy transition,” Rob Shaul, McDermott’s senior vice president of Low Carbon Solutions, adds. “Our integrated delivery model, with self-perform construction capabilities and portfolio of McDermott-owned, globally diversified, module fabrication yards means we can offer CHW a repeatable modular implementation solution that is expected to maximize value, reduce risk and provide quality assurance.”

Earlier this year, Houston-based Element Fuels completed the pre-construction phase of its hydrogen-powered clean fuels refinery and combined-cycle power plant in the Port of Brownsville — a project that McDermott is also providing FEED services for.

Also recently, McDermott secured an agreement to work on Canada's first commercial green hydrogen and ammonia production facility.

Houston lab develops reactor that sustainably turns waste into ammonia

seeing green

A team of Rice University engineers has developed a reactor design that can decarbonize ammonia production, produce clean water and potentially have applications in further research into other eco-friendly chemical processes.

Led by Rice associate professor Haotian Wang, the team published a study this month in the journal Nature Catalysis that details how the new reactor system sustainably and efficiently converts nitrates (common pollutants found in industrial wastewater and agricultural runoff) into ammonia, according to the university. The research was supported by Rice and the National Science Foundation.

“Our findings suggest a new, greener method of addressing both water pollution and ammonia production, which could influence how industries and communities handle these challenges,” Wang says in a statement. “If we want to decarbonize the grid and reach net-zero goals by 2050, there is an urgent need to develop alternative ways to produce ammonia sustainably.”

Other methods of creating ammonia include the Haber-Bosh process and electrochemical synthesis. The Haber-Bosh process requires large-scale centralized infrastructure and high temperature and pressure conditions. Meanwhile, electrochemical synthesis requires a high concentration of additive chemicals.

According to Rice, the new reactor requires less additive chemicals than the electrochemical synthesis, allowing nitrates to be converted more sustainably. The reactor relies on an innovative porous solid electrolyte as well as recyclable ions and a three-chamber system to improve the reaction’s efficiency.

Additionally, this development provides an effective water decontamination method.

“We conducted experiments where we flowed nitrate-contaminated water through this reactor and measured the amount of ammonia produced and the purity of the treated water,” Feng-Yang Chen, a Rice graduate student who is the lead author on the study, says. “We discovered that our novel reactor system could turn nitrate-contaminated water into pure ammonia and clean water very efficiently, without the need for extra chemicals. In simple terms, you put wastewater in, and you get pure ammonia and purified water out.”

Pedro Alvarez, the George R. Brown Professor of Civil and Environmental Engineering, director of the Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT) and the Water Technologies Entrepreneurship and Research (WaTER) Institute at Rice, says the reactor is "very timely and important" for growing cities that must deal with nitrate-contaminated groundwater supplies it.

"Conventional nitrate removal in drinking water treatment involves ion exchange or membrane filtration by reverse osmosis, which generates brines and transfers the nitrate problem from one phase to another,” he continues.

Wang's lab has been making headlines in recent years for innovative processes and technologies focused on the energy transition.

Last year, the lab published a study in Nature detailing a new technology that uses electricity to remove carbon dioxide from air capture to induce a water-and-oxygen-based electrochemical reaction, generating between 10 to 25 liters of high-purity carbon using only the power of a standard lightbulb.

In 2022, Rice reported that Wang’s lab in the George R. Brown School of Engineering had also replaced rare, expensive iridium with ruthenium, a more abundant precious metal, as the positive-electrode catalyst in a reactor that splits water into hydrogen and oxygen.

The lab received a portion of $10.8 million in research grants from the Houston-based Welch Foundation for research focused on converting carbon dioxide into useful chemicals, such as ethanol, last year. And Solidec, founded by Ryan Duchanois and Yang Xia from Wang's Lab, also received a $100,000 award from Rice as part of the One Small Step Grant program.

Wang has also been named among one of the most-cited researchers in the world.

ExxonMobil’s low-carbon hydrogen project in Baytown adds Air Liquide as partner

team work

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.

Oxy subsidiary granted landmark EPA permits for carbon capture facility

making progress

Houston’s Occidental Petroleum Corp., or Oxy, and its subsidiary 1PointFive announced that the U.S Environmental Protection Agency approved its Class VI permits to sequester carbon dioxide captured from its STRATOS Direct Air Capture (DAC) facility near Odessa. These are the first such permits issued for a DAC project, according to a news release.

The $1.3 billion STRATOS project, which 1PointFive is developing through a joint venture with investment manager BlackRock, is designed to capture up to 500,000 metric tons of CO2 annually and is expected to begin commercial operations this year. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted. Major companies, such as Microsoft and AT&T, have secured carbon removal credit agreements through the project.

The permits are issued under the Safe Drinking Water Act's Underground Injection Control program. The captured CO2 will be stored in geologic formations more than a mile underground, meeting the EPA’s review standards.

“This is a significant milestone for the company as we are continuing to develop vital infrastructure that will help the United States achieve energy security,” Vicki Hollub, Oxy president and CEO, said in a news release.“The permits are a catalyst to unlock value from carbon dioxide and advance Direct Air Capture technology as a solution to help organizations address their emissions or produce vital resources and fuels.”

Additionally, Oxy and 1PointFive announced the signing of a 25-year offtake agreement for 2.3 million metric tons of CO2 per year from CF Industries’ upcoming Bluepoint low-carbon ammonia facility in Ascension Parish, Louisiana.

The captured CO2 will be transported to and stored at 1PointFive’s Pelican Sequestration Hub, which is currently under development. Eventually, 1PointFive’s Pelican hub in Louisiana will include infrastructure to safely and economically sequester industrial emissions in underground geologic formations, similar to the STRATOS project.

“CF Industries’ and its partners' confidence in our Pelican Sequestration Hub is a validation of our expertise managing carbon dioxide and how we collaborate with industrial organizations to become their commercial sequestration partner,” Jeff Alvarez, President of 1PointFive Sequestration, said in a news release.

1PointFive is storing up to 20 million tons of CO2 per year, according to the company.

“By working together, we can unlock the potential of American manufacturing and energy production, while advancing industries that deliver high-quality jobs and economic growth,” Alvarez said in a news release.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

CenterPoint reports progress on grid improvements ahead of 2025 hurricane season

grid resilience

As part of an ongoing process to make Houston better prepared for climate disasters, CenterPoint Energy announced its latest progress update on the second phase of the Greater Houston Resiliency Initiative (GHRI).

CenterPoint reported that it has completed 70 percent of its resiliency work and all GHRI-related actions are expected to be complete before the official start of the 2025 hurricane season.

"Our entire CenterPoint Houston Electric team is focused on completing this historic suite of grid resiliency actions before the start of hurricane season,” Darin Carroll, Senior Vice President of CenterPoint's Electric Business, said in a news release. “That is our goal, and we will achieve it. To date, we have made significant progress as part of this historic effort.”

CenterPoint’s resiliency solutions include clearing higher-risk vegetation across thousands of miles of power lines, adding thousands more automation devices capable of self-healing, installing thousands of storm-resistant poles, and undergrounding hundreds of miles of power lines.

CenterPoint's GHRI efforts, which entered a second phase in September 2024, aim to improve overall grid resiliency and reliability and are estimated to reduce outages for customers by more than 125 million minutes annually, according to the company. It has undergrounded nearly 350 miles of power lines, about 85 percent of the way toward its target of 400 miles, which will help improve resiliency and reduce the risk of outages. CenterPoint also aims to install the first of 100 new local weather monitoring stations by June 1.

In March, CenterPoint cleared 655 miles of high-risk vegetation near power lines, installed 1,215 automated reliability devices capable of self-healing, and added an additional 3,300 storm-resilient poles.

In April, CenterPoint will begin building a network of 100 new weather monitoring stations, which will provide 24/7 weather monitoring and storm response preparation.

“We will continue to work every day to complete these critical improvements as part of our company's goal of building the most resilient coastal grid in the country,” Carroll added in the release.
