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.

Founded by brother-and-sister team Moji and Tara Karimi in 2017, Cemvita uses synthetic biology to turn carbon dioxide into chemicals and alternative fuels.

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.

Houston Innovation Awards honor Don Kendall Jr. with posthumous​ Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.
