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.

Houston clean hydrogen producer teams up with O&G for series of pilots

piling on pilots

Gold H2, a Houston-based producer of clean hydrogen, is teaming up with a major U.S.-based oil and gas company as the first step in launching a 12-month series of pilot projects.

The tentative agreement with the unnamed oil and gas company kicks off the availability of the startup’s Black 2 Gold microbial technology. The technology underpins the startup’s biotech process for converting crude oil into proprietary Gold Hydrogen.

The cleantech startup plans to sign up several oil and gas companies for the pilot program. Gold H2 says it’s been in discussions with companies in North America, Latin America, India, Eastern Europe and the Middle East.

The pilot program is aimed at demonstrating how Gold H2’s technology can transform old oil wells into hydrogen-generating assets. Gold H2, a spinout of Houston-based biotech company Cemvita, says the technology is capable of producing hydrogen that’s cheaper and cleaner than ever before.

“This business model will reshape the traditional oil and gas industry landscape by further accelerating the clean energy transition and creating new economic opportunities in areas that were previously dismissed as unviable,” Gold H2 says in a news release.

The start of the Black 2 Gold demonstrations follows the recent hiring of oil and gas industry veteran Prabhdeep Singh Sekhon as CEO.

“With the proliferation of AI, growth of data centers, and a national boom in industrial manufacturing underway, affordable … carbon-free energy is more paramount than ever,” says Rayyan Islam, co-founder and general partner at venture capital firm 8090 Industries, an investor in Gold H2. “We’re investing in Gold H2, as we know they’ll play a pivotal role in unleashing a new dawn for energy abundance in partnership with the oil industry.”

Houston company breaks ground on 'world's largest' geothermal project with next-generation tech

coming soon

Houston-based cleantech startup Fervo Energy has broken ground on what it's describing as the "world’s largest next-gen geothermal project."

Fervo says the a 400-milliwatt geothermal energy project in Cape Station, Utah, will start delivering carbon-free power to the grid in 2026, with full-scale production beginning in 2028.

The project, in southwest Utah, is about 240 miles southwest of Salt Lake City and about 240 miles northeast of Las Vegas. Cape Station is adjacent to the U.S. Department of Energy’s Frontier Observatory for Research in Geothermal Energy (FORGE) and near the Blundell geothermal power plant.

The company says Cape Station will generate about 6,600 construction jobs and 160 full-time jobs.

“Beaver County, Utah, is the perfect place to deploy our next-generation geothermal technology,” Tim Latimer, co-founder and CEO of Fervo, says in a news release. “The warmth and hospitality we have experienced from the communities of Milford and Beaver have allowed us to embark on a clean energy journey none of us could have imagined just a few years ago.”

In February, the U.S. Bureau of Land Management gave its blessing to the project, allowing Fervo to undertake exploration activities at the site.

“Geothermal innovations like those pioneered by Fervo will play a critical role in extending Utah’s energy leadership for generations to come,” says Utah Gov. Spencer Cox, who attended the groundbreaking ceremony.

Since being founded in 2017, Fervo has raised more than $180 million in funding. Its highest-profile investors are billionaires Jeff Bezos, Richard Branson and Bill Gates. They’re backing Fervo through Breakthrough Energy Ventures, whose managing director sits on Fervo’s board of directors.

Other investors include the Canada Pension Plan Investment Board (CPP Investments), DCVC, Devon Energy, Liberty Energy, Helmerich & Payne, Macquarie, the Grantham Foundation for the Protection of the Environment, Impact Science Ventures, and Prelude Ventures.

Fervo aims to generate more than one gigawatt of geothermal energy by 2030. On average, one gigawatt of power can provide electricity for 750,000 homes. Two coal-fired power plants can generate roughly the same amount of electricity.

Earlier this year, Fervo announced results of a test at Nevada’s Project Red site, which will supply power to Google data centers in the Las Vegas area. Fervo says the 30-day well test established Project Red as the “most productive enhanced geothermal system in history,” the company says. The test generated 3.5 megawatts of electricity.

In 2021, Fervo and Google signed the world’s first corporate agreement to produce geothermal power. Under the deal, Fervo will generate five megawatts of geothermal energy for Google through the Nevada project, which is set to go online later this year.

Houston subsea firm Zupt acquired in offshore tech deal

m&a activity

Houston-based Zupt LLC, a provider of advanced metrology, inspection, and engineering services for offshore energy and renewable projects, has been acquired by Columbus, Ohio-based Rosenxt Holding USA for an undisclosed amount.

Rosenxt says the deal, which closed July 21, represents another step in its long-term strategy to build a portfolio of technology and engineering capabilities for the subsea market in the energy sector.

“Our ambition has always been to think decades ahead,” Hermann Rosen, chairman of Switzerland-based Rosenxt Group, the parent company of Rosenxt Holding USA, said in a news release.

“The future of subsea and offshore industries will be shaped by intelligent technologies that fundamentally change how critical infrastructure is explored, installed, inspected and operated,” he added. “Zupt is another important building block in this vision.”

Rosenxt says offshore operators and installation contractors face pressure to execute subsea projects more efficiently amid workforce shortages, weather concerns, tougher safety standards, and rising capital and operating expenses.

“The offshore sector continues to embrace technologies that enhance data quality, reduce operational risk, and improve decision-making across the asset lifecycle,” Houston M&A attorney Amelia Zhang, who led law firm Norton Rose Fulbright’s representation of Zupt, added in the release.

Rosenxt provides services for the subsea market that combine sensing, robotics, AI, analytics and engineering. Zupt complements those services with offerings for operations, such as high-resolution 3D inspection, digital twin generation, and inspection and engineering technologies for subs.

Zupt President Keith Vickery founded the company in 2005.

Vickery says Zupt “has focused on solving some of the subsea industry’s most demanding marine construction and inspection challenges through innovative engineering, operational experience, and close collaboration with our customers.”

Mordor Intelligence estimates the value of the subsea market will climb from $19.75 billion this year to $25.03 billion in 2031. North America represents the largest segment of the global market.

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."
