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.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

Record $9.6M fine for Houston-based co. after Gulf of Mexico oil spill

In the news

Pipeline safety regulators on Monday, January 5, assessed their largest fine ever against the company responsible for leaking 1.1 million gallons of oil into the Gulf off the coast of Louisiana in 2023. But the $9.6 million fine isn’t likely to be a major burden for Third Coast to pay.

This single fine is close to the normal total of $8 million to $10 million in all fines that the Pipeline and Hazardous Materials Safety Administration hands out each year. But Third Coast has a stake in some 1,900 miles of pipelines, and in September, the Houston-based company announced that it had secured a nearly $1 billion loan.

Pipeline Safety Trust Executive Director Bill Caram said this spill “resulted from a company-wide systemic failure, indicating the operator’s fundamental inability to implement pipeline safety regulations,” so the record fine is appropriate and welcome.

“However, even record fines often fail to be financially meaningful to pipeline operators. The proposed fine represents less than 3% of Third Coast Midstream’s estimated annual earnings,” Caram said. “True deterrence requires penalties that make noncompliance more expensive than compliance.”

The agency said Third Coast didn't establish proper emergency procedures, which is part of why the National Transportation Safety Board found that operators failed to shut down the pipeline for nearly 13 hours after their gauges first hinted at a problem. PHMSA also said the company didn't adequately assess the risks or properly maintain the 18-inch Main Pass Oil Gathering pipeline.

The agency said the company “failed to perform new integrity analyses or evaluations following changes in circumstances that identified new and elevated risk factors” for the pipeline.

That echoed what the NTSB said in its final report in June, that “Third Coast missed several opportunities to evaluate how geohazards may threaten the integrity of their pipeline. Information widely available within the industry suggested that land movement related to hurricane activity was a threat to pipelines.”

The NTSB said the leak off the coast of Louisiana was the result of underwater landslides, caused by hazards such as hurricanes, that Third Coast, the pipeline owner, failed to address despite the threats being well known in the industry.

A Third Coast spokesperson said the company has been working to address regulators' concerns about the leak, so it was taken aback by some of the details the agency included in its allegations and the size of the fine.

“After constructive engagement with PHMSA over the last two years, we were surprised to see aspects of the recent allegations that we believe are inaccurate and exceed established precedent. We will address these concerns with the agency moving forward," the company spokesperson said.

The amount of oil spilled in this incident was far less than the 2010 BP oil disaster, when 134 million gallons were released in the weeks following an oil rig explosion, but it could have been much smaller if workers in the Third Coast control room had acted more quickly, the NTSB said.

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."
