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.

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Houston hypersonic engine co. completes first successful test flight

Taking Off

Houston-based Venus Aerospace successfully completed the first U.S. flight test of its proprietary engine at a demonstration at Spaceport America in New Mexico.

Venus’ next-generation rotating detonation rocket engine (RDRE) is supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA and aims to enable vehicles to travel four to six times the speed of sound from a conventional runway. The recent flight test was the first of an American-developed engine of its kind.

"With this flight test, Venus Aerospace is transforming a decades-old engineering challenge into an operational reality,” Thomas d'Halluin, managing partner at Airbus Ventures, an investor in Venus, said in a news release. “Getting a rotating detonation engine integrated, launch-ready, and validated under real conditions is no small feat. Venus has shown an extraordinary ability to translate deep technical insight into hardware progress, and we're proud to support their bold approach in their attempt to unlock the hypersonic economy and forge the future of propulsion."

Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel. It is designed to be affordable and scalable for defense and commercial systems.

The RDRE is also engineered to work with the company's air-breathing detonation ramjet, the VDR2, which helps enable aircraft to take off from a runway and transition to speeds exceeding Mach 6. Venus plans for full-scale propulsion testing and vehicle integration of this system. Venus’ ultimate goal is to develop a Mach 4 reusable passenger aircraft, known as the Stargazer M4.

"This milestone proves our engine works outside the lab, under real flight conditions," Andrew Duggleby, Venus co-founder and chief technology officer, said in the release. "Rotating detonation has been a long-sought gain in performance. Venus' RDRE solved the last but critical steps to harness the theoretical benefits of pressure gain combustion. We've built an engine that not only runs, but runs reliably and efficiently—and that's what makes it scalable. This is the foundation we need that, combined with a ramjet, completes the system from take-off to sustained hypersonic flight."

The hypersonic market is projected to surpass $12 billion by 2030, according to Venus.

"This is the moment we've been working toward for five years," Sassie Duggleby, CEO and co-founder of Venus Aerospace, added. "We've proven that this technology works—not just in simulations or the lab, but in the air. With this milestone, we're one step closer to making high-speed flight accessible, affordable, and sustainable."

Houston startup with unique engine tech reports milestone testing results

high-speed travel

A Houston-headquartered hardtech company that's working on technology to enable hypersonic travel has announced a partnership with NASA to test its tech.

Venus Aerospace has partnered with NASA’s Marshall Space Flight Center in Huntsville, Alabama, on what is reportedly the longest sustained tests of a rotating detonation rocket engine, also known as an RDRE.

“Venus believes strongly in the performance step-change that RDREs bring for both hypersonic and space applications. The partnership with NASA has been key in maturing this new technology.” Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in a news release.

The company's engine injector, which used regeneratively-cooled RDRE architecture, was tested in a "flight-like manner," according to the company. The technology operated successfully for 4 minutes of hotfire testing — a significant improvement, as engine tests of this type last for only 1 to 2 seconds, according to Venus.

"This long-duration hotfire means RDRE’s have retired a major risk area and are able to move into the few remaining steps before a flight demonstration," reads the press release from Venus.

As Venus continues to develop its technology for research, defense, and commercial missions, it will continue to work with NASA, which is also looking into RDRE technology for lunar and martian landers, in-space operations and logistics, and other deep space missions, per the release, because RDREs are more compact, efficient, and versatile than traditional rocket engines.

"Venus has entered into a second-year contract with NASA to provide engine parts for research and development of NASA’s RDRE," the news release continues. "In year two, NASA, with Venus’s support, will test different propellant combinations on hardware, to operate at even higher thrust levels and to demonstrate efficiency gains promised by the detonation engine."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sarah "Sassie" Duggleby in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round.

San Antonio company breaks ground on 347MW solar project outside of Houston

coming soon

Crews have broken ground on the forthcoming 347-megawatt direct-current SunRoper Solar project in Wharton County, Texas, that will add capacity to the ERCOT grid.

The solar project, which is slated to begin operations in December 2027, will provide electricity to an undisclosed Fortune 100 company under a long-term power purchase agreement, according to a news release.

San Antonio’s OCI Energy and Israel's Arava Power are developing the project. It's being financed by ING Capital and constructed by Louisiana-based WHC Inc. The project received $394 million in construction financing in February.

"SunRoper demonstrates how strategic partnerships can help meet Texas' growing demand for electricity through investments in critical energy infrastructure," Sabah Bayatli, president of OCI Energy, said in the release.

Project partners, landowners and company executives attended a groundbreaking event for SunRoper on Sept. 1 at the site outside of the Houston metro area. The companies say they are advancing this energy project to strengthen grid reliability and to help deliver affordable power to one of the highest-demand areas in the state.

“WHC is proud to serve as EPC contractor on the SunRoper Solar project, bringing our construction expertise to bear on a facility that will deliver meaningful power to the Houston region,” Randel Badeaux, president of power North America for WHC, added in the news release. “This groundbreaking reflects months of careful planning and coordination with OCI Energy, Arava Power and our project partners, and we look forward to executing a safe, high-quality build through to completion in 2027.”

OCI Energy currently operates several utility-scale solar and battery energy storage system projects outside of the San Antonio area, and has five other projects under construction outside of San Antonio and Waco, with more than 30 under development in Arkansas, Mississippi, Georgia, Colorado and Alberta, Canada. The company also has existing projects in New Jersey and Georgia.

In $2 billion deal, NVIDIA takes 20% stake in Woodlands-based Lancium

power play

With an initial investment of $2 billion, AI chip manufacturer NVIDIA just acquired a 20 percent stake in The Woodlands-based Lancium, which develops large-scale campuses that combine AI data centers and onsite power supplies.

Lancium recently announced the investment but didn’t disclose the dollar amount. The Information news website reported NVIDIA’s investment totaled $2 billion, with the possibility of an additional $1 billion if Lancium achieves certain milestones.

Dealroom.co calls NVIDIA’s investment a “form of supply-chain insurance.”

NVIDIA “is gaining exposure to the scarce physical assets that determine whether its chips can be deployed,” Dealroom.co says. “The move makes Nvidia look less like a pure chip company and more like an allocator of infrastructure capacity.”

Investment precedes possible IPO in 2027

Thanks to NVIDIA’s cash infusion, Lancium and its portfolio of land and power connections carry an enterprise value of about $10 billion, according to The Information.

The investment should enable Lancium to expand as it explores a potential IPO next year, The Information reported.

Neither Lancium nor NVIDIA is responding to requests for comment about the deal.

Lancium’s marquee project is a 1,000-acre data center and power generation campus in West Texas for the $500 billion Stargate initiative. Stargate, a joint venture comprising MGX, OpenAI, Oracle and SoftBank, is building data centers equipped to handle AI-level workloads.

“Epicenter of energy and AI infrastructure”

Founded in 2017, Lancium has 4 gigawatts of leased capacity and a more than 15-gigawatt development pipeline. In 2024, Blackstone Energy Transition Partners invested about $500 million in Lancium, giving Blackstone a roughly 50 percent stake.

“This partnership with NVIDIA is a strong testament to Lancium’s position at the epicenter of energy and AI infrastructure … . We look forward to continuing to partner with these leading companies to help power the next generation of AI innovation,” Bilal Khan, senior managing director at Blackstone, said in a release.

Through the NVIDIA partnership, Lancium’s data center and power generation campuses will use the tech company’s “AI factory” platform, including software, computing, and networking capabilities. This will give NVIDIA customers and partners access to power capacity that supports heavy AI workloads.

“We have spent years assembling the power, the land, and the infrastructure expertise needed to deliver AI data center capacity at a scale the world has never seen,” Michael McNamara, co-founder and CEO of Lancium, said in the release.

“Partnering with NVIDIA — the definitive technology platform for AI computing — ensures that every campus in our portfolio will be deployed with the industry’s most advanced technology and that NVIDIA’s customers will have access to the capacity they need to compete and lead in the AI era.”

U.S. oil giant Chevron confirms it will expand operations in Venezuela

O&G News

Oil giant Chevron confirmed that it will expand operations in Venezuela after President Donald Trump announced an ambitious deal to develop the nation’s oil reserves and give the Pentagon a stake in the profits.

Chevron, the only U.S. oil company with a major presence in Venezuela, said Wednesday that it has been assigned additional acreage in the Orinoco Belt, where it has active operations. The company plans to invest more than $7 billion over the next five years, with the goal of more than doubling its current production to about 600,000 barrels a day.

“Chevron’s history in Venezuela spans more than a century, and our expanded position reflects our confidence in the country’s deep resource potential,” CEO Mike Wirth said in a prepared statement.

Venezuela holds the world's largest proven reserves, totaling more than 303 billion barrels of crude oil, according to OPEC's 2025 Annual Statistical Bulletin. Saudi Arabia is a distant second with 267 billion barrels.

Yet because Venezuela's energy infrastructure is severely degraded and the nation is operating under international sanctions, its daily production is just over 1 million barrels, compared with the 10 million to 11 million barrels that Saudi Arabia produces each day. The U.S. produces almost 14 million barrels per day.

Chevron, the second-largest U.S. oil company, has had a presence in Venezuela since 1923.

“President Trump’s mission in Venezuela is straightforward. The mission is to bring peace, freedom, opportunity and prosperity to the people of Venezuela,” Energy Secretary Chris Wright said Wednesday in Caracas, Venezuela. “I believe the deals that are signed today – tens of billions of dollars of investment, ultimately many thousands of jobs – are critical in starting this ball rolling of peace, opportunity and prosperity for everyone in Venezuela.”

The White House confirmed Monday that it is partnering with North American Blue Energy Partners, NABEP, as part of Trump ’s push to tap into Venezuela’s oil industry.

Yet the agreement has been met with skepticism from energy experts who say it will take years to revive Venezuela’s oil industry, which is in disarray after years of neglect.

There are also questions about whether Venezuela’s acting president, Delcy Rodríguez, has the authority to give NABEP 100-year rights over 17 oil fields with reserves of 65 billion barrels — and whether future Venezuelan or American administrations would overturn the agreement.

Venezuela's constitution states that arrangements like the one that the United States announced this week must be approved by the National Assembly, which has not happened, wrote Ian Vásquez, vice president for international studies at the Cato Institute.

“The deal lacks legitimacy since it was agreed to with a dictatorship that has clung to power for decades through violence and by committing what was probably the largest electoral fraud in Latin American history in 2024,” Vásquez wrote. “The agreement was also reached under overwhelming pressure, military and otherwise, from the United States. As such, any future Venezuelan democracy will question the deal, thus undermining confidence in the current arrangement.”

Wright on Wednesday told reporters during a joint press conference with Rodríguez pushed back on criticism.

“This is a deal that’s a massive win and benefit for the people of the United States of America and a massive win for the people of Venezuela," he said. "Because what it’s going to do is take resources that are underground, not helping anyone, and invest capital and money and technology and bring them to the surface to better the lives of Venezuelans, better supply energy to Americans.”

Trump has eyed Venezuela’s oil since the January capture of then-President Nicolás Maduro and has pressed to get U.S. businesses back into the country. “We have Exxon going in, we have Chevron going in. We have our big oil companies going in,” he said that same month.

He suggested again on Monday that other U.S. oil majors were preparing for a return, though other than Chevron, there is no evidence of that.

Exxon Mobil CEO Darren Woods said in January that Venezuela was “ uninvestable.” An Exxon spokesman said this week that “nothing has changed.”

The history of U.S. oil majors in Venezuela explains the hesitation.

Venezuela nationalized its oil industry in 1976 and created the state-owned company Petróleos de Venezuela S.A. A second nationalization occurred in 2007, when President Hugo Chávez pushed foreign oil companies into state-controlled joint ventures and seized the assets of companies that refused. Chevron agreed to a joint venture. Others, including Exxon and ConocoPhillips, refused, and Venezuela took their assets.

Trump has said that the agreement with Venezuela would “substantially lower” gasoline prices in the U.S. However, analyst have repeatedly warned that Venezuela’s dilapidated oil infrastructure will require years of restoration work and tens of billions of dollars to resuscitate.

“It could take 2 to 4 years to get new greenfield facilities online in the Orinoco region,” Amy Jaffe, director of the Global Energy, Climate, and Sustainability Lab at New York University, said in an email. "Other places where there is no pipeline and other kinds of support infrastructure could take longer.”

Meanwhile, the national average price for a gallon of regular gasoline jumped overnight to $4.12, according to the motor club AAA. That is 93 cents more than it cost at this point last year.
