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

Houston innovator on the impact of facade enhancement on the energy transition

guest column

Imagine a world where outdated building facades transform overnight into modern marvels without the chaos of construction or the burden of exorbitant costs.

In the recent podcast episode on Energy Tech Startups, Anas Al Kassas, the CEO of INOVUES, unveils a groundbreaking technology that promises just that. This isn't just about a facelift; it's about revolutionizing energy efficiency, embracing smart-class innovations, and redefining the aesthetics of urban landscapes.

The Advantages of Facade Technology

One of the key advantages Al Kassas highlighted was the ability to significantly reduce both the cost and environmental impact of upgrading building facades. Al Kassas explained that by utilizing INOVUES' technology, the existing systems can be updated and improved without the need for removing or discarding the windows. This approach not only saves on material costs but also avoids disruption during installation. Additionally, the fast installation process and lower labor costs further contribute to the overall cost-effectiveness of the solution.

The Role of Design Aesthetics in Building Upgrades

While energy efficiency is a primary driver for building upgrades, Al Kassas emphasized the importance of design aesthetics in the commercial real estate market. He explained that modernizing the appearance of older buildings, which may still perform well but suffer from outdated perceptions, can attract more tenants and make them more competitive. With INOVUES' solution, building owners have the opportunity to improve the aesthetics of their facades by incorporating the latest glass technologies, colors, and frit patterns (translucent patterns on glass). This not only enhances the building's appearance but also contributes to glare reduction and customization options for different tenants' needs.

The Potential for Rentable Facades

During the conversation, Al Kassas speculated about the potential for rentable facades powered by INOVUES' technology. Just as Apple offers an upgrade plan for its devices, this concept proposes a similar model for building owners to continually incorporate the latest technologies every few years. By avoiding upfront costs and providing immediate benefits such as lower energy bills, improved tenant satisfaction, and a more sustainable building, this rentable facade approach could revolutionize the industry and make energy-efficient upgrades more accessible for a wider range of buildings.

The Current Funding Landscape and Future Growth

INOVUES' journey in securing funding, as discussed in the podcast, sheds light on the challenges faced by energy tech startups. The CEO highlighted the importance of timing and identifying the right investors who share the vision and understand the industry landscape. Despite the difficulties, INOVUES has successfully raised capital, including participation from a multinational building technology company. The company's next goal is to secure a series A funding round to scale their operations and expand their footprint in the market.

INOVUES' technology represents a sustainable solution for upgrading building facades without the need for extensive removal or disruptions. The combination of energy efficiency, improved design aesthetics, and the potential for rentable facades showcases the versatility and value of the company's technology. As the demand for sustainable building solutions continues to grow, and regulatory changes support energy efficiency projects, INOVUES is poised to make a significant impact in the industry. By focusing on both environmental and economic benefits, they are positioning themselves as a key player in the energy tech startup landscape.

Houston sustainability startup secures major milestone for energy efficient tool

patent progress

A Houston company that retrofits windows with smart glass innovations to reduce energy use is celebrating a handful of patents across North America and China.

INOVUES announced it secured several new patents from the United States Patent and Trademark Office, the Canadian Intellectual Patent Office, and the China National Intellectual Property Administration.

“These newly awarded patents reinforce our commitment to innovation and position us as a trusted partner for investors and industry partners,” says Anas Al Kassas, INOVUES founder and CEO, in a news release.

The company now has a total of four patents granted in the United States, Canada, and China, and four more patents pending in the United States, Canada, and the European Union. Additionally, INOVUES has trademark protection granted in the EU, United Kingdom, and China.

INOVUES's unique window treatment — its Insulating Glass Retrofit (IGR) and Secondary Glass Retrofit (SWR) technologies — directly impacts the built environment. The process includes 70 percent fewer materials compared to traditional methods and building owners see a 40 percent reduction in reduction in energy consumption following installation.

Last year, the company raised $2.75 million in venture funding. Kassas said at the time that the funding was slated o be used to scale up the team and identify the best markets to target customers, adding that he was looking for regions with rising energy rates and sizable incentives for companies making energy efficient changes.

"We were able to now implement our technology in over 4 million square feet of building space — from Boston, Seattle, Los Angeles, New York City, Portland, and very soon in Canada," he said in a December episode of the Houston Innovators Podcast.

Texas ranks below average on most energy-efficient states report

room to improve

Despite being home to a booming energy sector, Texas ranks below average on a new list of the country’s most and least energy-efficient states.

The list, compiled by personal finance website WalletHub, puts Texas at No. 34 for energy efficiency. It ranked 27th for energy efficiency of homes and 41st for energy efficiency of cars. Texas improved by one spot on the 2026 report, after coming in at No. 35 last year and No. 36 in 2024.

California took the top spot on the list this year, beating out Vermont, which claimed the No. 1 rank in 2025. South Carolina ranked No. 48. Due to data limitations, Alaska and Hawaii were excluded from WalletHub’s analysis.

In the WalletHub study, California had the lowest residential energy consumption per capita and the third-highest efficiency for home energy. At the bottom of the list, South Carolina ranked 48th for energy efficiency of homes and 35th for energy efficiency of cars.

Here’s who joined California in the top 5:

No. 2 Vermont
No. 3 New York
No. 4 Washington
No. 5 Massachusetts

WalletHub notes the average U.S. family spends at least $2,000 per year on utilities, and the average consumer spent $2,411 on gasoline in 2024.

The U.S. Department of Energy estimates that adopting energy-efficient measures in the home could reduce a family’s utility costs by as much as 25 percent. As for gas, the agency found a more fuel-efficient vehicle could save the average driver more than $1,000 per year.

“Energy efficiency doesn’t just help save the planet — it also helps save you money by lowering the amount of electricity, gas, oil, or other types of energy you need to consume,” WalletHub analyst Chip Lupo says.

“While there are some steps you can take to become more energy-efficient on your own, living in the right area can give you a big boost,” he adds. “For example, certain states have much better public transportation systems that minimize your need to drive, at least in big cities. Some places also have better-constructed buildings that retain heat better during the winter or stay cooler during the summer.”

WalletHub compiled the listing using data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration, and Federal Highway Administration.

Utility Global's H2Gen named one of the best inventions of 2026

Best of 2026

One of the year's most buzzworthy innovations comes from a Houston-based leader in the energy transition. Utility Global's H2Gen recently made Time magazine’s list of the 300 best inventions of 2026.

The H2Gen is an innovative system that produces low-cost clean hydrogen from water and industrial off-gases. The company says the process doesn’t require electricity, a notable claim since hydrogen production typically consumes a lot of power.

"Using a tubular electrochemical cell containing a proprietary electrolyte and water, the company can turn industrial off-gases into hydrogen at scale—no extra electricity required," writes Time. "Bonus: the process also pulls out carbon dioxide as a separate stream, where it can be captured and kept out of the atmosphere.

CEO Parker Meeks tells Time, it's “a practical pathway to decarbonize existing industrial assets."

The startup is on a roll. It has raised $100 million so far in an ongoing Series D round to offer its decarbonization technology at industrial scale around the world.

H2Gen is joined by 10 other inventions with Texas connections onTime's list, as well as one "special mention."

In North Texas, they are:

Samsung
Plano-based Samsung Electronics America pulled off a hat trick this year, with three products making Time’s list. First up is the Galaxy S26 Ultra smartphone. It packs a more powerful camera, Galaxy AI features, and pro-level content creation tools. But Time singled out its new built-in privacy display as the phone’s “biggest selling point.”

Samsung’s Bespoke AI Family Hub refrigerator also got smarter. When AI first came to the Family Hub in 2024, it could recognize some fresh foods, but you still had to log packaged items by hand, Time noted. Now, with Google Gemini built in, the fridge can identify more than 2,000 packaged foods, read handwritten labels, and warn you when food is about to expire. It then uses what’s inside to build grocery lists and suggest recipes.

And for gamers, there’s the Odyssey G8 monitor. Its 6K resolution leapfrogs the 4K standard, delivering what Samsung calls “exceptional visual clarity and detail” on a screen big enough for gaming and multitasking.

OxeFit
Plano-based OxeFit’s XS1 Peak is about the size of a treadmill but works like an entire gym. It can be set up for strength training, simulated skiing or kayaking, Pilates, or rowing. What makes it stand out is a built-in virtual spotter. According to Time, the machine “uses AI, computer vision and sensors to correct the user’s form, change resistance in the middle of a rep and reduce the weight when the user is struggling, much like a human spotter.”

EssilorLuxottica
EssilorLuxottica, the French eyewear giant whose U.S. headquarters is in Farmers Branch, makes Essilor Stellest lenses. The lenses correct nearsightedness while also slowing the eye growth that makes it worse over time. Stellest is the first and only eyeglass lens authorized by the U.S. Food and Drug Administration to control myopia, Time said. The lenses look like regular glasses but contain 1,021 tiny lenslets. In a U.S. trial of kids ages 6-12, myopia progression slowed by an average of 71 percent over two years compared with standard lenses.

Helpany
Helpany, a startup based in Phoenix that manufactures its devices in DFW, makes Paul, a ceiling-mounted gadget that uses radar and AI to spot subtle changes in how residents move and flag those at higher risk of falling. Helpany says the technology can cut falls by as much as 72 percent.

Aurora Innovation
Aurora, based in Pittsburgh with a corporate and operations hub in Coppell, rolled out its second-generation Driver 2 system in July. By September, Driver 2 trucks had logged more than 500,000 driverless miles without a single at-fault crash, Time reported, and the company expects 200 of them on the road by the end of 2026.

Colossal Biosciences
Dallas-based Colossal Biosciences built an artificial egg by placing an ultra-thin, transparent silicone membrane inside a rigid 3D-printed cup, letting scientists watch the embryo develop. Twenty-six chickens have already been hatched.

In Austin, they are:
Cedar Park-based Hyliion landed on Time’s list with its Karno Power Module, a modular generator designed to produce power wherever it’s needed. The Karno represents a big pivot for the company. Hyliion got its start building electrified powertrains for 18-wheelers before shifting into power generation after acquiring the Karno generator technology from GE Aerospace. Founded in Pittsburgh in 2015, the company relocated to Cedar Park in 2018.

The other Austin-associated honoree is Moment Energy. As more electric vehicles hit the road, a growing number of their batteries are nearing retirement, while demand for power keeps climbing. Moment Energy found a way to tackle both problems at once. The company’s Megafactory 1, which opened in Vancouver, Canada, in June, turns old EV batteries into modular energy storage systems for hospitals, factories, data centers, and other big power users. “Our goal is to make sure these batteries don’t end up in landfills,” founder Edward Chiang told Time.

In the “Special Mentions” category, Austin-based Renzoe Box gained notice for its refillable custom makeup palette for on-the-go people. Licensed architect René Graham designed the box. She graduated from Houston's Rice University, and was born and raised in Dallas.

Houston researchers develop heating method to recover critical minerals from e-waste

hot new research

Researchers at Rice University have developed a new technique to efficiently recycle electronic waste and harvest critical minerals using rapid heating.

Most electronic devices use flame-retardant plastic. The plastic is formulated from a critical metal called antimony.

However, recapturing antimony is typically a challenging task since it first has to be released from the plastic. As it is released, other compounds can form, such as organic bromides, which are toxic and difficult to capture. However, the organic bromides can also be reused and have applications in industrial chemicals when safely captured.

“Conventionally heating the plastic releases the antimony in a volatile and difficult-to-collect form as well as creating and releasing hazardous organic bromide compounds,” Leo Haoxin Ye, first author of the paper and a graduate student at Rice, said in a news release. “Other options are risky or more impractical, such as using strong acids, organic solvents or multistep treatment options.”

To address this issue, leading Rice chemistry professor James Tour, Ye and their team adapted Tour’s flash Joule heating technique, which heats materials to hundreds of degrees Celsius in milliseconds, according to Rice.

The team ground up flame-retardant plastic waste and placed it between two sheets of electrically heated carbon paper before using what’s known as isothermal-clamped flash Joule heating to release and collect the antimony.

The team found that limiting the time the plastic spent in the high temperature range dramatically reduced the production of the hazardous organic bromide compounds. The plastic remained between 200 degrees and 500 degrees Celsius for only 9.4 milliseconds, according to Rice.

Through the process, the team recovered 90 percent of antimony from tested materials and converted 83 percent of the bromide into hydrogen bromide. Their findings were published this month in the journal Nature Chemical Engineering.

“Isothermal-clamped flash Joule heating could improve the speed, safety and practicality of antimony recovery from discarded flame-retardant plastics,” Tour added in the release. “This represents an important step forward to conserving and reusing our critical antimony supply while also regenerating bromide salts for reuse.”

The study noted that the world is currently trending toward producing 82 million metric tons of flame-retardant plastic waste by 2030, which adds to the fact that e-waste is the fastest-growing solid waste stream in the world.

The research was funded by the Air Force Office of Scientific Research and the U.S. Army Corps of Engineers.
