4 biggest challenges of Houston-based sustainability startups

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 EnergyCapital's sister site, 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.

    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

    Texas City ammonia plant acquired by Yara in $1.3 billion deal

    Ammonia Acquisition

    Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

    The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

    The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

    During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

    The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

    Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

    “Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

    Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

    However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

    Houston hypersonic engine company lands $91M to accelerate production

    Clean Speed

    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.
