Electrification and automation company ABB, whose U.S. headquarters for its Energy Industries business is in Houston, has tentatively agreed to supply power for a $10 billion hydrogen project in South Texas.

Under a new memorandum of understanding, ABB plans to collaborate with Houston-based Green Hydrogen International on the Hydrogen City project. The first phase of the project is expected to generate 280,000 tons of green hydrogen per year. This green hydrogen will then be converted to one million tons of green ammonia each year.

“Together, we will enable efforts to decarbonize global industry and progress towards a net-zero future,” Brandon Spencer, president of ABB Energy Industries, says in a news release.

The memorandum of understanding calls for ABB’s technology to be assessed for delivery of solar and onshore wind energy to the 2.2-gigawatt electrolyzer facility at Hydrogen City.

The project will store up to 24,000 tons of green hydrogen in underground salt caverns. A 75-mile pipeline to the nearby Corpus Christi energy port will carry the green hydrogen to an ammonia production facility. At this facility, green hydrogen will be turned into green ammonia that’ll be shipped to Europe and Asia.

Green Hydrogen International is in talks with companies interested in using green hydrogen from Hydrogen City as feedstock for sustainable aviation fuel and e-methane.

Hydrogen City will serve a global green ammonia market whose value is projected to reach $17.9 billion by 2030. Construction on Hydrogen City is scheduled to start in 2026, with initial production set for 2030.

Green Hydrogen International unveiled the multiphase Hydrogen City project in 2022, saying it would be “the world’s largest green hydrogen production and storage hub.” At his month’s CERAWeek in Houston, officials provided an update on Hydrogen City.

“Ammonia has the potential to support decarbonization efforts as part of the energy transition through its use as an alternative fuel for heavy transport such as shipping, as well as its current major use in fertilizer production,” ABB says in the news release.

Last October, Green Hydrogen International announced a Hydrogen City partnership with Japanese oil and gas giant Inpex, whose U.S. outpost is in Houston.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
