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.

What EPA’s carbon capture and storage permitting announcement means for Texas

The View From HETI

Earlier this month, Texas was granted authority by the federal government for permitting carbon capture and storage (CCS) projects. This move could help the U.S. cut emissions while staying competitive in the global energy game.

In June, the U.S. Environmental Protection Agency (EPA) proposed approving Texas’ request for permitting authority under the Safe Drinking Water Act (SDWA) for Class VI underground injection wells for carbon capture and storage (CCS) in the state under a process called “primacy.” The State of Texas already has permitting authority for other injection wells (Classes I-V). In November, the EPA announced final approval of Texas’ primacy request.

Why This Matters for Texas

Texas is the headquarters for virtually every segment of the energy industry. According to the U.S. Energy Information Administration, Texas is the top crude oil- and natural-gas producing state in the nation. The state has more crude oil refineries and refining capacity than any other state in the nation. Texas produces more electricity than any other state, and the demand for electricity will grow with the development of data centers and artificial intelligence (AI). Simply put, Texas is the backbone of the nation’s energy security and competitiveness. For the nation’s economic competitiveness, it is important that Texas continue to produce more energy with less emissions. CCS is widely regarded as necessary to continue to lower the emissions intensity of the U.S. industrial sector for critical products including power generation, refining, chemicals, steel, cement and other products that our country and world demand.

The Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) has supported efforts to bring CCUS to a broader commercial scale since the initiative’s inception.

“Texas is uniquely positioned to deploy CCUS at scale, with world-class geology, a skilled workforce, and strong infrastructure. We applaud the EPA for granting Texas the authority to permit wells for CCUS, which we believe will result in safe and efficient permitting while advancing technologies that strengthen Texas’ leadership in the global energy market,” said Jane Stricker, Executive Director of HETI and Senior Vice President, Energy Transition at the Greater Houston Partnership.

What is Primacy, and Why is it Important?

Primacy grants permitting authority for Class VI wells for CCS to the Texas Railroad Commission instead of the EPA. Texas is required to follow the same strict standards the EPA uses. The EPA has reviewed Texas’ application and determined it meets those requirements.

Research suggests that Texas has strong geological formations for CO2 storage, a world-class, highly skilled workforce, and robust infrastructure primed for the deployment of CCS. However, federal permitting delays are stalling billions of dollars of private sector investment. There are currently 257 applications under review, nearly one-quarter of which are located in Texas, with some applications surpassing the EPA’s target review period of 24 months. This creates uncertainty for developers and investors and keeps thousands of potential jobs out of reach. By transferring permitting to the state, Texas will apply local resources to issue Class VI permits across the states in a timely manner.

Texas joins North Dakota, Wyoming, Louisiana, West Virginia and Arizona with the authority for regulating Class VI wells.

Is CCS safe?

A 2025 study by Texas A&M University reviewed operational history and academic literature on CCS in the United States. The study analyzed common concerns related to CCS efficacy and safety and found that CCS reduces pollutants including carbon dioxide, particulate matter, sulfur oxides and nitrogen oxides. The research found that the risks of CCS present a low probability of impacting human life and can be effectively managed through existing state and federal regulations and technical monitoring and safety protocols.

What’s Next?

The final rule granting Texas’ primacy will become effective 30 days after publication in the Federal Register. Once in effect, the Texas Railroad Commission will be responsible for permitting wells for carbon capture, use and storage and enforcing their safe operation.

Houston energy expert: How the U.S. can turn carbon into growth

Guets Column

For the past 40 years, climate policy has often felt like two steps forward, one step back. Regulations shift with politics, incentives get diluted, and long-term aspirations like net-zero by 2050 seem increasingly out of reach. Yet greenhouse gases continue to rise, and the challenges they pose are not going away.

This matters because the costs are real. Extreme weather is already straining U.S. power grids, damaging homes, and disrupting supply chains. Communities are spending more on recovery while businesses face rising risks to operations and assets. So, how can the U.S. prepare and respond?

The Baker Institute Center for Energy Studies (CES) points to two complementary strategies. First, invest in large-scale public adaptation to protect communities and infrastructure. Second, reframe carbon as a resource, not just a waste stream to be reduced.

Why Focusing on Emissions Alone Falls Short

Peter Hartley argues that decades of global efforts to curb emissions have done little to slow the rise of CO₂. International cooperation is difficult, the costs are felt immediately, and the technologies needed are often expensive. Emissions reduction has been the central policy tool for decades, and it has been neither sufficient nor effective.

One practical response is adaptation, which means preparing for climate impacts we can’t avoid. Some of these measures are private, taken by households or businesses to reduce their own risks, such as farmers shifting crop types, property owners installing fire-resistant materials, or families improving insulation. Others are public goods that require policy action. These include building stronger levees and flood defenses, reinforcing power grids, upgrading water systems, revising building codes, and planning for wildfire risks. Such efforts protect people today while reducing long-term costs, and they work regardless of the source of extreme weather. Adaptation also does not depend on global consensus; each country, state, or city can act in its own interest. Many of these measures even deliver benefits beyond weather resilience, such as stronger infrastructure and improved security against broader threats.

McKinsey research reinforces this logic. Without a rapid scale-up of climate adaptation, the U.S. will face serious socioeconomic risks. These include damage to infrastructure and property from storms, floods, and heat waves, as well as greater stress on vulnerable populations and disrupted supply chains.

Making Carbon Work for Us

While adaptation addresses immediate risks, Ken Medlock points to a longer-term opportunity: turning carbon into value.

Carbon can serve as a building block for advanced materials in construction, transportation, power transmission, and agriculture. Biochar to improve soils, carbon composites for stronger and lighter products, and next-generation fuels are all examples. As Ken points out, carbon-to-value strategies can extend into construction and infrastructure. Beyond creating new markets, carbon conversion could deliver lighter and more resilient materials, helping the U.S. build infrastructure that is stronger, longer-lasting, and better able to withstand climate stress.

A carbon-to-value economy can help the U.S. strengthen its manufacturing base and position itself as a global supplier of advanced materials.

These solutions are not yet economic at scale, but smart policies can change that. Expanding the 45Q tax credit to cover carbon use in materials, funding research at DOE labs and universities, and supporting early markets would help create the conditions for growth.

Conclusion

Instead of choosing between “doing nothing” and “net zero at any cost,” we need a third approach that invests in both climate resilience and carbon conversion.

Public adaptation strengthens and improves the infrastructure we rely on every day, including levees, power grids, water systems, and building standards that protect communities from climate shocks. Carbon-to-value strategies can complement these efforts by creating lighter, more resilient carbon-based infrastructure.

CES suggests this combination is a pragmatic way forward. As Peter emphasizes, adaptation works because it is in each nation’s self-interest. And as Ken reminds us, “The U.S. has a comparative advantage in carbon. Leveraging it to its fullest extent puts the U.S. in a position of strength now and well into the future.”
