Houston-based Utility Global, a maker of decarbonization-focused gas production technology, has raised $53 million in an ongoing series C round.

Among the participants in the round are Canada’s Ontario Power Generation Pension Plan, the XCarb Innovation Fund operated by Luxembourg-based steel company ArcelorMittal, Houston-based investment firm Ara Partners, and Saudi Aramco’s investment arm.

Also, Utility Global and ArcelorMittal have agreed to develop at least one decarbonization facility at an ArcelorMittal steel plant.

The latest infusion of cash will support the rollout of Utility Global’s eXERO technology, including establishment of the company’s first commercial facilities in 2026.

“With the successful completion of its demonstration program at a commercial steel facility resulting in the first hydrogen ever produced from blast furnace off-gasses in a single reactor, the company has shifted to commercial deployments,” Utility Global says in a news release.

Utility Global’s technology enables reduction of greenhouse gas emissions along with generation of low-carbon fuels and chemicals.

“Our eXERO solution is the first of its kind to convert process gasses into clean hydrogen in a single reactor, onsite, in a cost-effective manner that extends the life of existing customer assets and processes while providing significant emissions reductions,” says Claus Nussgruber, CEO of Utility Global.

Top Houston-based sustainability startups share their 4 biggest challenges

houston innovation awards

Six Houston-area sustainability startups have been named finalists in the 2023 Houston Innovation Awards, but they didn't achieve this recognition — as well as see success for their businesses — without any obstacles.

The finalists were asked what their biggest challenges have been. From funding to market adoption, the sustainability companies have had to overcome major obstacles to continue to develop their businesses.

The awards program — hosted by InnovationMap, and Houston Exponential — will name its winners on November 8 at the Houston Innovation Awards. The program was established to honor the best and brightest companies and individuals from the city's innovation community. Eighteen energy startups were named as finalists across all categories, but the following responses come from the finalists in the sustainability category specifically.

    Click here to secure your tickets to see who wins.

    1. Securing a commercial pilot

    "As an early-stage clean energy developer, we struggled to convince key suppliers to work on our commercial pilot project. Suppliers were skeptical of our unproven technology and, given limited inventory from COVID, preferred to prioritize larger clients. We overcame this challenge by bringing on our top suppliers as strategic investors. With a long-term equity stake in Fervo, leading oilfield services companies were willing to provide Fervo with needed drilling rigs, frack crews, pumps, and other equipment." — Tim Latimer, founder and CEO of Fervo Energy

    2. Finding funding

    "Securing funding in Houston as a solo cleantech startup founder and an immigrant with no network. Overcome that by adopting a milestone-based fundraising approach and establishing credibility through accelerator/incubator programs." — Anas Al Kassas, CEO and founder of INOVUES

    "The biggest challenge has been finding funding. Most investors are looking towards software development companies as the capital costs are low in case of a risk. Geothermal costs are high, but it is physical technology that needs to be implemented to safety transition the energy grid to reliable, green power." — Cindy Taff, CEO of Sage Geosystems

    3. Market adoption

    "Market adoption by convincing partners and government about WHP as a solution, which is resource-intensive. Making strides by finding the correct contacts to educate." — Janice Tran, CEO and co-founder of Kanin Energy

    "We are creating a brand new financial instrument at the intersection of carbon markets and power markets, both of which are complicated and esoteric. Our biggest challenge has been the cold-start problem associated with launching a new product that has effectively no adoption. We tackled this problem by leading the Energy Storage Solutions Consortium (a group of corporates and battery developers looking for sustainability solutions in the power space), which has opened up access to customers on both sides of our marketplace. We have also leveraged our deep networks within corporate power procurement and energy storage development to talk to key decision-makers at innovative companies with aggressive climate goals to become early adopters of our products and services." — Emma Konet, CTO and co-founder of Tierra Climate

    4. Long scale timelines

    "Scaling and commercializing industrial technologies takes time. We realized this early on and designed the eXERO technology to be scalable from the onset. We developed the technology at the nexus of traditional electrolysis and conventional gas processing, taking the best of both worlds while avoiding their main pitfalls." — Claus Nussgruber, CEO of Utility Global

    Looking for a job? These 2023 Houston Innovation Awards finalists are hiring

    calling all applicants

    More than half of this year's startup finalists in the Houston Innovation Awards are hiring — who's looking for a job at one of the best startups in Houston?

    When submitting their applications for the 2023 Houston Innovation Awards, which is taking place November 8 at Silver Street Studios, every startup was asked if it's hiring. Twenty-seven of the 35 startup honorees said yes, ranging from over 20 to just one positions open at each company.

    Click here to secure your tickets to see which of these growing startups win.

    Here's a look at which of the top startups in Houston are seeking new team members.

    Double-digit growth

    When it comes to the awards finalists looking to scale their team by 10 or more new hires, five finalists are growing rapidly.

    Medical practice software platform RepeatMD, fresh off a $40 million raise — which included participation from Houston-based Mercury — is reportedly growing its team. The company, which has 115 employees already, is looking for over 20 new hires.

    Female-owned business Feelit Technologies, which is using nanotechnology for preventive maintenance to eliminate leaks, fires and explosions, increase safety and reduce downtime, has 50 employees, and only three of which are in Houston – for now. The company hopes to grow its team by 12 to 15 employees in Houston alone.

     Square Robot, an energy industry-focused robotics company that recently grew its presence in Houston, is hiring 10 to 30 new team members. It has 24 employees already in Houston.

    Solugen, an alternative chemicals business, has around 140 of its 200 employees in Houston. The company, which has raised over $600 million to date, is hiring an additional 10 to 15 new hires.

    Additionally, Blue People, also a finalist in last year's awards, is hiring 25 new employees. The company was founded in 2015 in Mexico and relocated its primary operations to Houston in 2020. Blue People, which develops software innovation for its clients, has over 150 employees — 10 of whom, including C-level executives, are based in Houston. Some of the company's new hires will be based in town.

    Steady growth

    Four Houston startups are hiring within the six to 10 team member range — all with fairly significant employee counts already.

    A finalist in last year's awards too, Venus Aerospace, a hypersonics company on track to fly reusable hypersonic flight platforms by 2024, is again growing its team. With 48 on-site employees and 23 working remotely, Venus's team will add another five to 10 employees.

    Syzygy Plasmonics, a deep decarbonization company that builds chemical reactors designed to use light instead of combustion to produce valuable chemicals like hydrogen and sustainable fuels, has 112 employees in Houston and plans to hire another eight to its team.

    Lastly, Fervo Energy, which recently raised $10 million, has 63 full-time employees (34 in Houston, 29 outside of Houston) and looking to hire seven more.

    Houston team’s discovery brings solid-state batteries closer to EV use

    A Better Battery

    A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

    The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

    The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

    “This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

    A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

    However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

    Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

    “By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

    The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

    “It’s about making future energy storage more reliable for everyone,” Zhao added.

    The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

    University of Houston archaeologists make history with Mayan tomb discovery

    History in the Making

    Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

    The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

    The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

    During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

    The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

    "Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

    “The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

    The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.
