A fresh $12 million round of funding will enable Houston-based Citroniq Chemicals to propel planning, design, and construction of its first decarbonization plant.

An unidentified multinational energy technology company led the series A round, with participation from Houston-based Lummus Technology Ventures and cooperation from the State of Nebraska. The Citroniq plant, which will produce green polypropylene, will be located in Nebraska.

“Lummus’ latest investment in Citroniq builds on this progress and strengthens our partnership, working together to lower carbon emissions in the plastics industry,” Leon de Bruyn, president and CEO of Lummus Technology, says in a news release.

Citroniq is putting together a decarbonization platform designed to annually capture 2 million metric tons of greenhouse gas emissions at each plant. The company plans to invest more than $5 billion into its green polypropylene plants. Polypropylene is a thermoplastic resin commonly used for injection molding.

The series A round “is just the first step in our journey towards building multiple biomanufacturing hubs, boosting the Nebraska bioeconomy by converting local ethanol into valuable bioplastics,” says Kelly Knopp, co-founder and CEO of Citroniq.

Citroniq’s platform for the chemical and plastics industries uses technology and U.S.-produced ethanol to enable low-cost carbon capture. Citroniq’s process permanently sequesters carbon into a useful plastic pellet.

Lummus Technology licenses process technologies for clean fuels, renewables, petrochemicals, polymers, gas processing and supply lifecycle services, catalysts, proprietary equipment, and digital transformation.

Houston companies partner on sustainable plastics alternative

green polypropylene

Two Houston companies, Lummus Technology and Citroniq Chemicals, have paired up to build North American plants that produce green polypropylene.

Polypropylene is a thermoplastic used to manufacture items such as plastic packaging, plastic parts, medical supplies, textiles, and fibers. Green polypropylene is made from biomass.

Lummus and Citroniq say their first plant, set for completion in 2027, will produce 400,000 metric tons of green polypropylene each year. The plant will be at an undisclosed location in the Midwest.

In April, Lummus and Citroniq signed a letter of intent to develop Citroniq green polypropylene projects in North America using Lummus’ Verdenesuite of polypropylene technology. Their newly announced licensing and engineering agreements apply to the first of four planned facilities.

“This agreement demonstrates the progress we continue to make with Citroniq in establishing the first world-scale sustainable bio-polypropylene production process in North America,” Romain Lemoine, chief business officer for polymers and petrochemicals at Lummus, says in a news release.

“Combining Lummus’ leadership in polypropylene licensing with Citroniq’s carbon-negative production capabilities will help us meet the growing demand for bio-polypropylene and accelerate the decarbonization of the downstream energy industry,” Lemoine adds.

Citroniq says it’s investing more than $5 billion to expand its E2O process. The process produces carbon-negative plastics and hydrogen-and-carbon compounds called olefins from fully sustainable feedstocks. This eliminates the use of convention fossil-fuel hydrocarbons, Citroniq says.

Mel Badheka, principal and co-founder of Citroniq, says his company aims “to meet the market’s growing need for sustainable carbon-negative polypropylene at a competitive price.”

The global market for green polypropylene was valued at $123.5 billion in 2022, according to Grand View Research. Growth in the sector is being driven in part by the construction industry, the firm says.

Local energy innovators recognized at annual Houston Innovation Awards

the big winners

This week, the Houston innovation ecosystem celebrated big wins from the year, and members of the energy transition community were recognized alongside other innovators.

The Houston Innovation Awards honored over 40 finalists across categories, naming the 12 winners and honoring the two Trailblazer Legacy Awards at the event. The event, hosted at TMC Helix Park on November 14 named and celebrated the winners, which included four energy transition innovators.

Here's what energy leaders secured wins during the evening.

Corrolytics is a technology startup founded to solve microbiologically influenced corrosion problems for industrial assets. Co-founder and CEO Anwar Sadek says he's collected over $1 million in dilutive and non-dilutive funding from grants and other opportunities thanks to help from mentors. The company won both the Minority-Founded Business category and the People's Choice: Startup of the Year category.

"As a founder, I am always eager to assist and support fellow entrepreneurs, especially those navigating the unique challenges that come with being a BIPOC founder," he says. "With the guidance of mentors, I learned to master the complexities of the application process for grants and other funding opportunities. In turn, I actively share my experiences with other founders, helping them navigate similar paths."

Founded by CEO Cindy Taff, SageGeosystems is an energy company focused on developing and deploying advanced geothermal technologies to provide reliable power and sustainable energy storage solutions regardless of geography. The company secured the win in the Energy Transition Business category, alongside finalists Amperon, ARIX Technologies, Elementium Materials, InnoVent Renewables, and Tierra Climate.

"Sage Geosystems sets itself apart from competitors with its Geopressured Geothermal Systems, which can be deployed almost anywhere, unlike traditional geothermal technologies that require specific geographic conditions," Taff says. "This flexibility enables Sage to provide a reliable and virtually limitless power supply, making it ideal for energy-intensive applications like data centers."

A finalist in both the Investor of the Year and Ecosystem Builder categories, Juliana Garaizar is the founding partner of Energy Tech Nexus, invests with groups — such as Portfolia, Houston Angel Network, Business Angel Minority Association, and more — locally and beyond.

"I'm a hands on investor," she says. "I offer mentorship and industry and other investor connections. I take advisory roles and board observer seats."

This year, the Houston innovation community suffered the loss of two business leaders who left a significant impact on the ecosystem. Both individuals' careers were recognized with Trailblazer Legacy Awards.

One of the recipients was Scott Gale, executive director of Halliburton Labs, who received the award posthumously. He died on September 24. The award was decided on by the 2024 judges and InnovationMap. Gale was honored alongside Paul Frison, founder of the Houston Technology Center.

“I am immensely proud to honor these two remarkable individuals with the Trailblazer Award this year. It is fitting, as they represent two generations of building Houston’s ecosystem," 2023 Trailblazer Award recipient Brad Burke, managing director of the Rice Alliance and the associate vice president for industry and new ventures within Rice University's Office of Innovation, tells InnovationMap.

"Paul Frison was a pioneering leader who helped establish the Houston Technology Center and fostered the city’s tech ecosystem during the initial technology boom around the year 2000. Scott Gale, through his work at Halliburton Labs over the past five years, has been instrumental in launching Houston’s energy transition ecosystem," he continues. "Both have played pivotal roles in championing technology innovators.”

In honor of his son, Andrew Gale accepted the award with his daughter-in-law, Nicole, during the event.

Pipeline robotics: How this Houston startup is revolutionizing corrosion monitoring

listen now

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes."

But it's an industry Liu knows well, so she founded ARIX in 2017 and created a team of engineers to create the first iteration of the ARIX robot, which was at first made of wood, she says. Now, years later, the much-evolved robot moves up and down the exterior of the pipe, using its technology to scan the interior to evaluate corrosion. The technology works with ARIX's software to provide key data analysis.

With customers across the country and the world, ARIX has a strong foothold in downstream, but has garnered interest from other verticals as well — even working with NASA at one point, Liu says.

"Staying in downstream would be nice and safe for us, but we've been very lucky and have had customers in midstream, upstream, and even outside oil and gas and chemicals," she says. "We've gotten inquiries ranging from cosmetics plants to water or wastewater — essentially anything that's round or a pipe that can corrode, we can help with."

Liu, who goes into detail on the show about how critical establishing a positive company culture has been for ARIX, shares a bit about what it's been like growing her company in Houston.

"Houston being the Energy Capital of the World opens a lot of doors to both customers, investors, and employees in a way that's unparalleled. It is a great place to build a company because of that — you have all this expertise in this city and the surrounding areas that's hard to find elsewhere," she says. "Being such a hub — not only for energy, but in terms transportation — means it's easy for us to get to our customers from around the world."
