A new partnership between an energy and sustainability investor and a Houston-based company that focuses on cleaner solutions in the oil and gas industry will look into turning stranded natural gas into blue hydrogen.

New York-based Double Zero Holdings and SJ Environmental announced their new partnership this week in an effort to move forward the energy transition. According to the companies, stranded natural gas — mostly methane — usually remains unused where it is not economically viable to transport. By turning these gasses into into blue hydrogen, "the partnership mitigates methane and CO2 emissions while producing hydrogen—a clean fuel that could revolutionize multiple industries," reads the news release.

The initiative will use existing technologies, which can be reduced to the size of a standard shipping container, per the release.

"We're thrilled to partner with SJ Environmental to tackle one of the most pressing environmental issues today," Raja Ramachandran, managing partner of Double Zero Holdings, says in the release. "This collaboration allows us to turn stranded natural gas—a significant environmental liability—into a valuable resource, supporting the global shift toward cleaner energy."

The plan is to lower the amount of natural gas left wasted and provide a low-carbon alternative across transportation, manufacturing, and power generation.

"Our collaboration with Double Zero Holdings reflects our commitment to innovative, sustainable solutions," SJ Environmental Director John Chappell adds. "Together, we're setting a new standard for energy production, delivering hydrogen and food-grade CO₂ where natural gas would typically be flared."

Expert: Using data to reduce Houston’s oil and gas carbon footprint

guest column

Sustainability has been top of mind for all industries as we witness movements towards reducing carbon emissions. For instance, last year, the Securities and Exchange Commission (SEC) proposed a new rule that requires companies to disclose certain climate-related activities in their reporting on a federal level. Now, industries and cities are scrambling to ensure they have strategies in the right place.

While the data behind sustainability poses challenges across industries, it is particularly evident in oil and gas, as their role in energy transition is of the utmost importance, especially in Texas. We saw this at the COP26 summit in Glasgow in November 2021, for example, in the effort to reduce carbon emissions on both a national and international scale and keep global warming within 1.5 degrees Celsius.

The event also made it clear achieving this temperature change to meet carbon neutrality by 2030 won’t be possible if organizations rely on current methods and siloed data. In short, there is a data problem associated with recent climate goals. So, what does that mean for Houston’s oil and gas industry?

Climate is a critical conversation – and tech can help

Houston has long been considered the oil and gas capital of the world, and it is now the epicenter of energy transition. You can see this commitment by the industry in the nature of the conferences as well as the investment in innovation centers.

In terms of the companies themselves, over the past few years each of the major oil and gas players have organized and grown their low carbon business units. These units are focused on bringing new ideas to the energy ecosystem. The best part is they are not working alone but joining forces to find solutions. One of the highest profile examples is ExxonMobil’s Carbon Capture and Underground Storage project (CCUS) which directly supports the Paris Agreement.

Blockchain technology is needed to improve transparency and traceability in the energy sector and backing blockchain into day-to-day business is key to identifying patterns and making decisions from the data.

The recent Blockchain for Oil and Gas conference, for instance, focused on how blockchain can help curate emissions across the ecosystem. Recent years have also seen several additional symposiums and meetings – such as the Ion and

Greentown Houston – that focus on helping companies understand their carbon footprint.

How do we prove the data?

The importance of harmonizing data will become even more important as the SEC looks to bring structure to sustainability reporting. As a decentralized, immutable ledger where data can be inputted and shared at every point of action, blockchain works by storing information in interconnected blocks and providing a value-add for insuring carbon offsets. To access the data inside a block, users first need to communicate with it. This creates a chain of information that cannot be hacked and can be transmitted between all relevant parties throughout the supply chain. Key players can enter, view, and analyze the same data points securely and with assurance of the data’s accuracy.

Data needs to move with products throughout the supply chain to create an overall number for carbon emissions. Blockchain’s decentralization offers value to organizations and their respective industries so that higher quantities of reliable data can be shared between all parties to shine a light on the areas they need to work on, such as manufacturing operations and the offsets of buildings. Baking blockchain into day-to-day business practice is key in identifying patterns over time and making data-backed decisions.

Oil and gas are key players

Cutting emissions is not a new practice of the oil and gas industry. In fact, they’ve been cutting emissions estimates by as much as 50 percent to avoid over-reporting.

The traditional process of reporting data has also been time-consuming and prone to human error. Manually gathering data across multiple sources of information delivers no real way to trace this information across supply chains and back to the source. And human errors, even if they are accidental, pose a risk to hefty fines from regulatory agencies.

It’s a now-or-never situation. The industry will need to pivot their approaches to data gathering, sharing, and reporting to commit to emissions reduction. This need will surely accelerate the use of technologies, like blockchain, to be a part of the energy transition. While the climate challenges we face are alarming, they provide the basis we need for technological innovation and the ability to accurately report emissions to stay in compliance.

The Energy Capital of the World, for good

To solve the climate crisis, confidence in emissions data is crucial. Blockchain provides that as well as transparency and reliability, all while maintaining the highest levels of security. The technology provides assurance that the data from other smart technologies, like connected sensors and the Internet of Things (IoT), is trustworthy and accurate.

The need for good data, new technology, and corporate commitment are all key to Houston keeping its title as the energy capital of the world – based on traditional fossil fuels as well as transitioning to clean energy.

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.
