Houston-based biotech company Cemvita has achieved a key production goal five years ahead of schedule.

Thanks to technology advancements, Cemvita is now capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita has quadrupled output at the Houston plant. The company had planned to reach this milestone in 2029.

Cemvita, founded in 2017, says this achievement paves the way for increased production capacity, improved operational efficiency, and an elevated advantage in the sustainable oil market.

“What’s so amazing about synthetic biology is that humans are just scratching the surface of what’s possible,” says Moji Karimi, co-founder and CEO of Cemvita. “Our focus on the first principles has allowed us to design and create new biotech more cheaply and faster than ever before.”

The production achievement follows Cemvita’s recent breakthrough in development of a solvent-free extraction bioprocess.

In 2023, United Airlines agreed to buy up to one billion gallons of sustainable aviation fuel from Cemvita’s first full-scale plant over the course of 20 years.

Cemvita’s investors include the UAV Sustainable Flight Fund, an investment arm of Chicago-based United; Oxy Low Carbon Ventures, an investment arm of Houston-based energy company Occidental Petroleum; and Japanese equipment and machinery manufacturer Mitsubishi Heavy Industries.

Houston-based biotech company Cemvita recently tapped two executives to help commercialize its sustainable fuel made from carbon waste.

Nádia Skorupa Parachin came aboard as vice president of industrial biotechnology, and Phil Garcia was promoted to vice president of commercialization.

Parachin most recently oversaw several projects at Boston-based biotech company Ginkjo Bioworks. She previously co-founded Brazilian biotech startup Integra Bioprocessos.

Parachin will lead the Cemvita team that’s developing technology for production of bio-manufactured oil.

“It’s a fantastic moment, as we’re poised to take our prototyping to the next level, and all under the innovative direction of our co-founder Tara Karimi,” Parachin says in a news release. “We will be bringing something truly remarkable to market and ensuring it’s cost-effective.”

Moji Karimi, co-founder and CEO of Cemvita, says the hiring of Parachin represents “the natural next step” toward commercializing the startup’s carbon-to-oil process.

“Her background prepared her to bring the best out of the scientists at the inflection point of commercialization — really bringing things to life,” says Moji Karimi, Tara’s brother.

Parachin joins Garcia on Cemvita’s executive team.

Before being promoted to vice president of commercialization, Garcia was the startup’s commercial director and business development manager. He has a background in engineering and business development.

Founded in 2017, Cemvita recently announced a breakthrough that enables production of large quantities of oil derived from carbon waste.

In 2023, United Airlines agreed to buy up to one billion gallons of sustainable aviation fuel from Cemvita’s first full-scale plant over the course of 20 years.

Cemvita’s investors include the UAV Sustainable Flight Fund, an investment arm of Chicago-based United; Oxy Low Carbon Ventures, an investment arm of Houston-based energy company Occidental Petroleum; and Japanese equipment and machinery manufacturer Mitsubishi Heavy Industries.

Houston cleantech company sees shining success with gold hydrogen

bling, bling

Houston-based cleantech startup Cemvita Factory is kicking things into high gear with its Gold Hydrogen product.

After successfully completing a pilot test of Gold Hydrogen in the oil-rich Permian Basin of West Texas, Cemvita has raised an undisclosed amount of funding through its new Gold H2 LLC spin-out. The lead investors are Georgia-based equipment manufacturer Chart Industries and 8090 Industries, an investment consortium with offices in New York City and Los Angeles.

Gold Hydrogen provides carbon-neutral hydrogen obtained from depleted oil and gas wells. This is achieved through bioengineering subsurface microbes in the wells to consume carbon and generate clean hydrogen.

Cemvita says it set up Gold H2 to commercialize the business via licensing, joint ventures, and outright ownership of hydrogen assets.

“We have incredible conviction in next-generation clean hydrogen production methods that leverage the vast and sprawling existing infrastructure and know-how of the oil and gas industry,” Rayyan Islam, co-founder and general partner of 8090 Industries, says in a news release.

Traditional methods of producing hydrogen without greenhouse gas emissions include electrolysis powered by renewable sources like wind, solar or water, according to Cemvita. However, production of green hydrogen through normal avenues eats up a lot of energy and money, the startup says.

By contrast, Cemvita relies on depleted oil and gas wells to cheaply produce carbon-free hydrogen.

“The commercialization and economics of the hydrogen economy will require technologies that produce the hydrogen molecule at a meaningful scale with no carbon emissions. Gold H2 is leading the charge … ,” says Jill Evanko, president and CEO of Chart Industries.

Investors in Cemvita include Oxy Low Carbon Ventures, an investment arm of Houston-based Occidental Petroleum, as well as BHP Group, Mitsubishi, and United Airlines Ventures.

Oxy Low Carbon Ventures and United Airlines Ventures are financing Cemvita’s work on sustainable jet fuel. United Airlines operates a hub at George Bush Intercontinental Airport Houston.

Houston biotech startup scores $5M to fuel sustainable aviation innovation

seeing green

Houston cleantech startup Cemvita Factory has scored a $5 million investment from United Airlines Ventures, the venture capital fund of the Chicago-based airline.

The equity investment is aimed at propelling commercialization of sustainable aviation fuel through a process involving carbon dioxide (CO2) and synthetic microbes.

Oxy Low Carbon Ventures, a subsidiary of Houston-based Occidental Petroleum that’s a founding investor in Cemvita, and United Airlines Ventures are financing the startup’s work on sustainable jet fuel. United Airlines operates a hub at George Bush Intercontinental/Houston Airport.

If that work pans out, the United and Occidental investment arms plan to form a joint venture to commercialize the technology. The joint venture might include construction of plants for the production of sustainable aviation fuel.

Sustainable aviation fuel, known as SAF, is an alternative to jet fuel that uses non-petroleum feedstock and offers lower greenhouse gas emissions.

Founded by brother-sister team Moji and Tara Karimi in 2017, Cemvita Factory relies on synthetic biology to turn carbon dioxide into chemicals and alternative fuels, including SAF. The startup, founded in 2017, is among the first companies to employ this technology to support heavy-industry decarbonization and find ways to take advantage of microbiology to convert CO2 into fuel.

“The use of SAF is a promising approach that we believe can significantly reduce global emissions from aviation and further decarbonization initiatives to combat climate change,” Richard Jackson, president of operations for U.S. onshore resources and carbon management at Occidental, says in a news release.

Cemvita is the third SAF-related startup to receive an investment from United Airlines Ventures.

The partnership among Cemvita, Occidental, and United is among many initiatives seeking to ramp up production of SAF. For instance, the U.S. Department of Energy is collaborating with the U.S. Department of Transportation, the U.S. Department of Agriculture, and other federal agencies to develop a strategy for scaling SAF technology.

The global SAF market is projected to grow from $219 million in 2021 to more than $15.7 billion by 2030, according to Research and Markets.

The International Air Transport Association says more than 370,000 flights have been fueled by SAF since 2016. Over 26.4 million gallons of SAF were produced last year.

Last month in France, aircraft manufacturer Airbus flew a A380 test jet for about three hours with one of the four engines operating solely on SAF. The three other engines ran on conventional fuel.

In December 2021, United flew a 737 MAX 8 jet from Chicago O’Hare International Airport to Washington Reagan National Airport outside Washington, D.C., with one of the two engines operating only on SAF. It was the first commercial flight with passengers aboard to use SAF in that capacity. The other engine ran on conventional fuel.

United CEO Scott Kirby, who was aboard the historic flight, said the flight was “not only a significant milestone for efforts to decarbonize our industry, but when combined with the surge in industry commitments to produce and purchase alternative fuels, we’re demonstrating the scalable and impactful way companies can join together and play a role in addressing the biggest challenge of our lifetimes.”

For now, airlines are allowed to use up SAF for up to 50 percent of the fuel on commercial flights.

Houston-based carbon negative biotech startup closes series A round

money moves

A promising Houston startup using biotechnology to reduce carbon emissions is celebrating the initial closing of its series A fundraising round.

Cemvita Factory announced the news of its round closing, but didn't disclose the amount raised. 8090 Partners, a new investment group of entrepreneurs turned investors, led the round. Existing investor Oxy Low Carbon Ventures also contributed, along with Seldor Capital, Climate Capital, and others.

Founded by brother-sister team Moji and Tara Karimi in 2017, the company's technology biomimics photosynthesis to take carbon dioxide and turn it into something else. Cemvita uses this synthetic biology to decarbonize heavy industry across chemical manufacturing, mining, and oil and gas.

"Decarbonizing heavy industry is one of the most critical challenges in addressing climate change," says Moji Karimi, who serves as CEO, in a news release. "Synthetic biology is now primed to revolutionize heavy industries because of its inherent low-carbon advantages, and Cemvita is taking the lead in identifying and derisking the key applications."

Cemvita is currently working. with a number of clients — including Oxy, which announced its pilot in April — to reduce their carbon footprints.

"We believe the adoption rate and market size growth of our target applications will only accelerate due to the urgency for a low-carbon energy transition," Karimi continues. "The future of manufacturing will be low-carbon biomanufacturing and the future of mining will be sustainable biomining."

According to the release, the fresh funds will go toward launching Cemvita's bio-hydrogen solution, as well as to support construction and operation of a bio-ethylene pilot plant with Oxy. The pilot project, which reported success in the lab, is expected to scale.

"While synthetic biology has proven to be effective in re-imagining food and proteins, we've long held a firm belief in synthetic biology's promise in the heavy industrial space, but have waited until we've seen the right technology and team to drive real innovation in the sector," says Rayyan Islam, partner at 8090 Partners, in the release. "Cemvita's technology is a fundamental game-changer that provides a real economic solution and major players across heavy industry have taken serious notice."

It's not just investors and industrial players who have taken notice. Cemvita won the recent GS Beyond Energy Innovation Challenge from Cleantech.org. The company was also selected as a cohort member at Carbon2Value Initiative.

"Cemvita's technology is truly revolutionary in its use of CO2 and as a resource to provide viable economic solutions as more and more companies seek ways to reduce their carbon footprint. We remain impressed and excited about Cemvita's technology's positive impact on Earth and beyond," says Sidney N. Nakahodo, founder and general partner of Seldor Capital, in the release.

Oxy taps Houston startup's carbon negative biotechnology for new pilot plant

sustainability moves

Occidental's venture arm — Oxy Low Carbon Ventures — has announced its plans to construct and operate a one metric ton per month bio-ethylene pilot plant featuring Houston-based Cemvita Factory's technology that biomimics photosynthesis to convert carbon dioxide into feedstocks.

The new plant will scale the process, which was jointly developed between Cemvita and OLCV, and is expected sometime next year, according to a press release from Oxy.

"Today bio-ethylene is made from bio-ethanol, which is made from sugarcane, which in turn was created by photosynthesizing CO2. Our bio-synthetic process simply requires CO2, water and light to produce bio-ethylene, and that's why it saves a lot of cost and carbon emissions," says Moji Karimi, co-founder and CEO of Cemvita Factory, in the release. "This project is a great example of how Cemvita is applying industrial-strength synthetic biology to help our clients lower their carbon footprint while creating new revenue streams."

Oxy and Cemvita have been working together for a while, and in 2019, OLCV invested an undisclosed amount into the startup. The investment, according to the release, was made to jointly explore how these advances in synthetic biology can be used for sustainability efforts in the bio-manufacturing of OxyChem's products.

"This technology could provide an opportunity to offer a new, non-hydrocarbon-sourced ethylene product to the market, reducing carbon emissions, and in the future benefit our affiliate, OxyChem, which is a large producer and consumer of ethylene in its chlorovinyls business," says Robert Zeller, vice president of technology at OLCV, in a news release.

Moji Karimi founded the company with his sister and Cemvita CTO, Tara, in 2017. The idea was to biomimic photosynthesis to take CO2 and turn it into something else. The first iteration of the technology turned CO2 into sugar — the classic photosynthesis process. Karimi says the idea was to create this process for space, so that astronauts can turn the CO2 they breathe out into a calorie source.

"Nature provided the inspiration," noted Dr. Tara Karimi, co-founder and CTO of Cemvita Factory. "We took a gene from a banana and genetically engineered it into our CO2-utilizing host microorganism. We are now significantly increasing its productivity with the goal to achieve commercial metrics that we have defined alongside OLCV."

A couple weeks ago, Moji Karimi joined the Houston Innovators Podcast to discuss growth and challenges Cemvita Factory faced.

"We're defining this new category for application of synthetic biology in heavy industries for decarbonization," he shares on the show. Stream the episode below.

UH secures $5M in philanthropic gifts to bolster engineering, nursing

major gifts

The University of Houston has received two significant philanthropic gifts to advance innovation and healthcare, the college announced this month.

Manmohan Singh Kalsi and Marie-Luise Schubert Kalsi granted $4 million to UH’s Cullen College of Engineering to support endowed and current funds for graduate fellowships and industry interest in the mechanical and aerospace fields.

The gift is the Department of Mechanical and Aerospace Engineering’s largest donation in years, according to UH, and will establish two endowed professorships to attract and retain leading faculty. It will also create the Kalsi Faculty Research Fund, which aims to take emerging research to the next level.

Additionally, UH says it will also bring industry experts to campus to present and collaborate with students via the forthcoming Kalsi Seminar Series.

Manmohan Kalsi earned both his master’s degree and Ph.D. in mechanical engineering from UH. He went on to found Sugar Land-based Kalsi Engineering in 1978, which pioneered hydrodynamic rotary sealing technology and valve technology for nuclear power plants. In 2014, he established an endowed professorship within Cullen College in honor of the late UH professor Gabriel Fazekas.

"This gift provides a tremendous boost to our department's strategic momentum,” Karolos Grigoriadis, chair of the Department of Mechanical and Aerospace Engineering, said in a news release. “By simultaneously supporting faculty, graduate researchers and collaborative seminars, the Kalsis are strengthening every part of our research enterprise and creating new opportunities for discovery, collaboration and student mentorship.”

Meanwhile, Houston’s The Hamill Foundation also gave a $1 million gift to UH’s Andy and Barbara Gessner College of Nursing. The funds will establish The Hamill Foundation Endowed Professorship in Community Care Nursing, to support a faculty member focused on community-based nursing education, partnerships, research, and outreach to underserved communities in Houston.

Additionally, the funding will go toward efforts to address nurse shortages through the newly established UH Health program. The Hamill Foundation has donated $6 million previously to UH through the years, but the latest $1 million is the largest single investment from the foundation to date.

“The Hamill Foundation continues to help us raise the bar for nursing education and address the nursing shortage,” Kathryn Tart, founding dean and professor at Gessner College and Humana Endowed Dean's Chair in Nursing, said in a news release. “The enduring commitment and generosity of The Hamill Foundation allow us to answer the call and educate generations of competent and caring nursing professionals.”

Both of the recent gifts help fund UH’s $1 billion Can’t Stop Houston: The Centennial Campaign. As of September, the university had raised more than $881 million. UH turns 100 years old in March 2027.

SpaceX's supersized Starship rocket launches into orbit for first time

Out in Space

SpaceX launched its enormous Starship into orbit for the first time Monday, September 28, and successfully delivered the most advanced Starlink satellites yet, but cut the flight short to ensure safety.

The spacecraft reentered over the Pacific and splashed down north of Hawaii three hours after blasting off from Texas. The company had been aiming for a 10-hour flight, spanning six full laps around Earth, to prove its readiness for NASA’s Artemis moon program.

Starship tipped over and erupted in flames upon splashdown, a dramatic end to the mission.

Elon Musk's Starship almost didn't make it to orbit when one of its engines shut down prematurely. But with everything else working well and the bad engine no longer needed, flight controllers decided, after several tense minutes, to proceed as planned.

“Starship is orbital,” Mission Control announced to cheers.

NASA Administrator Jared Isaacman congratulated SpaceX on reaching orbit and “managing every step in a safe, responsible and especially inspirational way.”

Rocket carries 26 of Musk's most advanced Starlink satellites

Musk’s showpiece rocket — the biggest and most powerful ever built — carried 26 of the latest Starlinks to join the 11,000 older models already providing internet service. They popped out of the spacecraft one by one, drawing more cheers from the SpaceX crowd at the Starbase launch site.

The decision to end the flight early came soon afterward. SpaceX said hours later in an online update that the decision was made “out of an abundance of caution” because of the early engine trouble.

It was Starship’s 14th full-scale launch from Texas’ southern tip in three years. Earlier test flights ventured no farther than the Indian Ocean halfway around the world, often crashing in flames and briefly skimming space.

This time, the intent was for SpaceX to circle the globe from an altitude of 170 miles (275 kilometers) — not just once but six times over almost 10 hours, ending with a Pacific splashdown near Chile. While Starship achieved the proper orbit, zipping along at 17,500 mph (28,000 kph), flight controllers opted to play it safe and bring it back several hours sooner, after just a couple of laps.

The first-stage booster was never meant to return to the Starbase launch site either, dropping instead into the Gulf of Mexico within minutes of the morning liftoff.

SpaceX wants to ensure that everything works before flying Starship back to Starbase. If the spacecraft breaks apart over land and rains debris onto people, “our popularity would diminish very rapidly,” Musk said at a business summit earlier this month. “That’s why we’re being extremely cautious here.”

Depending on the findings from Monday's orbital debut, the next Starship could return to the launch pad, where giant mechanical arms would grab the hovering spacecraft. If the catch works — Musk gives it even or slightly better odds — then SpaceX will refly the spacecraft by year’s end or early next year.

The 407-foot (124-meter) rocket was designed from the start to be fully reusable, a key to lowering launch costs. SpaceX managed to salvage the last Starship from the Indian Ocean in July. Engineers modified the newly launched Starship’s heat shield based on hands-on inspections of the recovered spacecraft, which is being tugged back to Starbase.

SpaceX wants Starship to be certified for orbital flight

SpaceX is pressing hard to certify Starship for orbital flight, a vital step toward moon and Mars travel.

NASA’s Artemis III mission is coming up as soon as next summer, a triple-launch docking exercise in orbit around Earth between an Orion capsule full of astronauts and competing lunar landers. Jeff Bezos’ Blue Moon would blast off first, followed by Orion — which would close in for a linkup — and then Musk’s Starship for a docking with Orion once Blue Moon is unleashed.

The next mission, Artemis IV, is slated for no sooner than 2028 and would have astronauts landing on the moon in either Blue Moon or Starship, whichever is ready first. Subsequent moonshots will alternate between the two billionaires’ landers.

Musk originally developed Starship for Mars, intending to launch scores of them with the red planet’s first settlers. For now, he plans to focus on the moon and use Starship to haul satellites into orbit by the truckload, phasing out the company’s frailer Falcon 9 rocket within several years. A second Starship launch site is nearing completion at Florida’s Kennedy Space Center and a third is planned for Louisiana.

Houston startup raises $2.4M for sleep apnea technology

sleep score

Houston-based Bairitone Health has closed an oversubscribed seed round and achieved a regulatory milestone, the company tells InnovationMap.

The healthtech startup, which is developing solutions and technology for untreated obstructive sleep apnea (OSA), raised $2.4 million, says CEO and co-founder Meagan Pitcher, exceeding its $2 million goal.

New York-based Golden Seeds, which invests in female entrepreneurs, led the round. Houston-based South Loop Ventures also participated, as well as MALIAM, Impact Invest Her and additional angel, venture, syndicate and family office investors. The company previously raised a pre-seed round of $435,000 in 2024.

Pitcher says the latest funding will go toward Bairitone's clinical site expansion, FDA-facing work and the continued product development of its SOMNAR technology.

"What I’m most excited about is what this lets us do next: expand our clinical testing, work with more patients and physicians, and keep improving based on what we learn," Pitcher said in a LinkedIn post.

SOMNAR is the company's noninvasive diagnostic platform for sleep apnea airway assessment. The platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

SOMNAR received Breakthrough Device Designation from the Food and Drug Administration in April. It is currently for investigational use only and is still pending FDA clearance. The new designation aims to help speed up development, assessment and review for premarket approval for medical devices, according to the FDA. It will also give Bairitone more opportunities to interact directly with FDA experts to make the approval process more efficient.

Bairitone was founded in 2022 in the Texas Medical Center's Biodesign program by Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators.

The company was a finalist for the Houston Innovation Awards in 2025 and 2024.
