Houston is home to some of the nation's largest oil and gas exploration and production firms, making it one of the world’s most important energy capitals. Growing regional support for pioneering clean tech, such as carbon capture, will help achieve the crucial transition to net zero whilst maintaining economic stability, boosting local industries and creating jobs.

According to the International Energy Agency (IEA), North America and Asia Pacific are expected to hold the largest share in carbon capture capacity. North America’s world-leading carbon capture potential comes as no surprise given the nation’s dominance in oil and gas, and ideal geology for sequestration.

The IEA’s recently published World Energy Outlook 2023 depicts a global market that is in transition. With more companies, world leaders and governments recognizing that a shift towards sustainable energy is both inevitable and transformative, the question is no longer whether we switch to clean energy, but rather how soon the transition can happen.

For every $1 in investment spending on fossil fuels globally, $1.8 is now being spent to develop clean energy, according to the IEA. Although the clean energy market has almost doubled in the past five years to reach an estimated $2.8 trillion in 2023, investment needs to hit $4.2 trillion per year by 2030 to achieve the universally shared goal of net zero. The IEA believes around 1 Gigaton of CO2 must be captured in 2030, rising to 6 Gigatons by 2050 to achieve the Net Zero Emissions by 2050 Scenario (termed NZE Scenario). This presents a tremendous opportunity for government stakeholders and the business community in Houston to turbocharge the economy and protect the planet from the impact of climate change.

While volatility around the energy market lingers, sustainable technologies remain one of the most dynamic areas of global energy investment. An essential ingredient to its success is bringing on board innovators, entrepreneurs, corporations, and financiers to ensure technology innovation is front and center in facilitating the clean energy transition.

Carbon capture technology is critical, but energy leaders and hard-to-abate industries are under pressure to move faster. To do that, the carbon capture industry must scale up its deployment and increase adoption if hard-to-abate sectors are to address the 30 percent of global CO2 emissions for which they are responsible. Governments have a pivotal role to play in providing financial, regulatory and policy incentives, facilitating a collaborative environment between financiers, hard-to-abate operators, and clean tech companies. While we are moving in the right direction, there is no room for complacency or procrastination given the short timescales for meaningful action.

Over the past several years, Carbon Clean, a global company that is revolutionizing carbon capture, has enjoyed significant expansion in North America. Following the passage of the Inflation Reduction Act (IRA) in August 2022, we saw huge interest in our modular industrial carbon capture technology almost overnight, resulting in a 64 percent increase in inquiries from the U.S. To meet this booming demand, we have opened a U.S. headquarters in Houston, and have plans to double our U.S. headcount to meet industry requirements for our scalable and cost-effective technology, CycloneCC. In short, the United States is poised to become our biggest market. Given our latest lead investor and partner is Houston-based Chevron New Energies, there is no better place than Houston to drive innovation in the country’s energy sector.

The IRA did more than just bring in new inquiries for our breakthrough technology – it also signaled to the energy sector that the federal government is getting serious about bringing emissions down. The impact of the IRA cannot be overstated, especially for the point-source carbon capture technology pioneered by Carbon Clean. While the IRA involves billions of dollars of public investment, it is set up in such a way that companies must make substantial investments first, acting as a down payment on fostering jobs and ensuring the business community is delivering ambitious climate action. The benefits are being felt locally as well – cities like Houston are at the forefront of what the IRA has to offer, taking advantage of these investments and reducing emissions.

Companies and stakeholders across the energy spectrum need to act together and act fast. With the dramatic growth required for carbon capture to have full effect, it will be essential for government, industry, and innovators to join together to concentrate on a number of projects and clusters. We are confident that with new cutting-edge technology and broad collaboration we can rapidly get the world on the right path to net zero.

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.
