bp’s Archaea Energy is the largest renewable natural gas (RNG) producer in the U.S., with an industry leading RNG platform and expertise in developing, constructing and operating RNG facilities to capture waste emissions and convert them into low carbon fuel.

Archaea partners with landfill owners, farmers and other facilities to help them transform their feedstock sources into RNG and convert these facilities into renewable energy centers.

Starlee Sykes, Archaea Energy’s CEO, shared more about bp’s acquisition of the company and their vision for the future.

HETI: bp completed its acquisition of Archaea in December 2022. What is the significance of this acquisition for bp, and how does it bolster Archaea’s mission to create sustainability and stability for future generations?

Starlee Sykes: The acquisition was an important move to accelerate and grow our plans for bp’s bioenergy transition growth engine, one of five strategic transition growth engines. Archaea will not only play a pivotal role in bp’s transition and ambition to reach net zero by 2050 or sooner but is a key part of bp’s plan to increase biogas supply volumes.

HETI: Tell us more about how renewable natural gas is used and why it’s an important component of the energy transition?

SS: Renewable natural gas (RNG) is a type of biogas generated by decomposing organic material at landfill sites, anaerobic digesters and other waste facilities – and demand for it is growing. Our facilities convert waste emissions into renewable natural gas. RNG is a lower carbon fuel, which according to the EPA can help reduce emissions, improve local air quality, and provide fuel for homes, businesses and transportation. Our process creates a productive use for methane which would otherwise be burned or vented to the atmosphere. And in doing so, we displace traditional fossil fuels from the energy system.

HETI: Archaea recently brought online a first-of-its-kind RNG plant in Medora, Indiana. Can you tell us more about the launch and why it’s such a significant milestone for the company?

SS: Archaea’s Medora plant came online in October 2023 – it was the first Archaea RNG plant to come online since bp’s acquisition. At Medora, we deployed the Archaea Modular Design (AMD) which streamlines and accelerates the time it takes to build our plants. Traditionally, RNG plants have been custom-built, but AMD allows plants to be built on skids with interchangeable components for faster builds.

HETI: Now that the Medora plant is online, what does the future hold? What are some of Archaea’s priorities over the next 12 months and beyond?

SS: We plan to bring online around 15 RNG plants in each of 2024 and 2025. Archaea has a development pipeline of more than 80 projects that underpin the potential for around five-fold growth in RNG production by 2030.

We will continue to operate around 50 sites across the US – including RNG plants, digesters and landfill gas-to-electric facilities.

And we are looking to the future. For example, at our Assai plant in Pennsylvania, the largest RNG plant in the US, we are in the planning stages to drill a carbon capture sequestration (CCS) appraisal well to determine if carbon dioxide sequestration could be feasible at this site, really demonstrating our commitment to decarbonization and the optionality in value we have across our portfolio.

HETI: bp has had an office in Washington, DC for many years. Can you tell us more about the role that legislation has to play in the energy transition?

SS: Policy can play a critical role in advancing the energy transition, providing the necessary support to accelerate reductions in greenhouse gas emissions. We actively advocate for such policies through direct lobbying, formal comments and testimony, communications activities and advertising. We also advocate with regulators to help inform their rulemakings, as with the US Environmental Protection Agency to support the finalization of a well-designed electric Renewable Identification Number (eRIN) program.

HETI: Science and innovation are key drivers of the energy transition. In your view, what are some of most exciting innovations supporting the goal to reach net-zero emissions?

SS: We don’t just talk about innovation in bp, we do it – and have been for many years. This track record gives us confidence in continuing to transform, change and innovate at pace and scale. The Archaea Modular Design is a great example of the type of innovation that bp supports which enables us to pursue our goal of net-zero emissions.

Beyond Archaea, we have engineers and scientists across bp who are working on innovative solutions with the goal of lowering emissions. We believe that we need to invest in lower carbon energy to meet the world’s climate objectives, but we also need to invest in today’s energy system, which is primarily hydrocarbon focused. It’s an ‘and’ not ‘or’ approach, and we need both to be successful.

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.
