An oil and gas exploration and production company has signed on to collaborate on a green hydrogen project in Texas to keep up with growing global market demand.

INPEX Corp. and Green Hydrogen International have agreed to a Joint Study Agreement to advance a South Texas hydrogen production facility called "Hydrogen City." The project's first phase will produce 280,000 tons per year of green hydrogen and 1 million tons per year of green ammonia. Construction is slated to begin in 2026 with commercial operation expected in 2029.

INPEX's "unparalleled expertise in large energy project development combined with a world-class marketing organization will provide enormous advantages to the Hydrogen City project and our goal of producing the world's lowest-cost green hydrogen by 2029," Brian Maxwell, CEO of GHI, says in a news release.

The partnership brings together both entities' expertise, with INPEX's experience developing large scale energy projects and marketing LNG to international customers. Meanwhile, GHI uses salt cavern storage and behind-the-meter renewable power to produce low-cost green hydrogen.

"I am excited to announce this green hydrogen project in Texas, which exemplifies our unwavering commitment to environmental leadership and innovation," INPEX Representative Director, President, and CEO Takayuki Ueda says in the release. "INPEX's dedication to a brighter, greener future remains steadfast, and this endeavor in Texas marks a pivotal step in our vision for a more sustainable tomorrow."

INPEX is also a part of a large-scale, low-carbon ammonia production and export project on the Houston Ship Channel that was anounced ealier this month.

Hydrogen City, located in South Texas atop the Peidras Pintas Salt Dome, was originally announced in March 2022. There will be a 75 mile pipeline from Hydrogen City to Corpus Christi, supplying a 1 Million Tonne Per Annum (MTPA) ammonia production facility and local off-takers.

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.
