Houston-based NanoTech Materials has closed a $29.4 million Series A.

The round was led by Austin-based HPI Real Estate & Investments. Houston-based Goose Capital and Austin-based Milliken & Company also participated.

Nanotech has developed its patented Insulative Ceramic Particle (ICP) technology, which reduces heat transfer in buildings and outdoor infrastructure, improving efficiency and safety. It's known for its Cool Roof Coat, Wildfire Shield and Insulative Coat: Cool Touch product lines.

With the new funding, Nanotech plans to scale operations and expand its market reach for its products.

“We’re addressing one of the pressing and urgent challenges facing infrastructure owners today: controlling energy costs and extending asset life,” Mike Francis, CEO and co-founder of NanoTech Materials, said in a news release. “This financing marks a transformative moment for us. It allows us to rapidly scale production and bring our high-performance materials to market faster, while delivering measurable cost savings and redefining what resilience looks like in today’s built environment.”

Nanotech launched in 2020 and was the first company selected for Halliburton Labs. It moved into a 43,000-square-foot space in Katy in 2023. It brought on new partners that expanded the company's reach in the Middle East and Singapore the following year. Its technology was recognized as one of Time magazine's 200 Best Inventions of 2024.

“We were early investors in Nanotech Materials and are pleased to continue supporting the company as it becomes a leader in breakthrough materials science and technology,” John Chaney, investor at Goose Capital and board member at NanoTech, added in the release. “NanoTech’s ability to elevate fire resilience and energy efficiency in the built environment is critical for strengthening and hardening infrastructure. Its pioneered approach is transforming current building standards and making our lives safer.”

The company has secured $34.4 million in total to date, according to the release. It raised an oversubscribed funding round in 2023 and a $5 million seed round in 2020.

Promising Houston startup expands energy efficiency product to Middle East, Singapore

big move

NanoTech Materials has announced a big expansion for its business.

The Houston company, which created a roof coating using nanotechnology that optimizes energy efficiency, has partnered with Terminal Subsea Solutions Marine Service SP to bring its products to the Gulf Cooperation Council and Singapore. TSSM will become a partner of Houston’s NanoTech Materials products, which will include the Cool Roof Coat, Vehicular Coat, and Insulative Coat for the GCC countries and Singapore.

NanoTech Materials technology that ranges from roof coatings on mid- to low-rise buildings to shipping container insulation to coating trucks and transportation vehicles will be utilized by TSSM in the partnership. NanoTech’s efforts are focused on heat mitigation that can reduce energy costs, enhance worker safety, and minimize business risks in the process.

“Businesses and communities within the GCC and Singapore feel the impact of extreme temperatures and longer Summers more acutely than any other region in the world,” Mike Francis, CEO of NanoTech Materials, says in a news release. “We have an opportunity to make a real impact here through reduced energy load, cooler and safer working conditions, and a reduced carbon emissions output from the hottest, driest place on earth. We are incredibly excited to be partnering with our colleagues at TSSM to bring this powerful technology to the region.”

One of the areas that will benefit from this collaboration is the Middle East. The GCC region is characterized by a desert climate, which has average annual temperature reaching 107.6°F and summer peaks climbing as high as 130°F. The effects of these extreme conditions can be dangerous for workers especially with strict labor laws mandating midday work bans under black flag conditions, which can result in productivity losses as well.

NanoTech’s proprietary technology, the Insulative Ceramic Particle (ICP), will be used to address challenges in energy efficiency and heat control in the logistics and built environment sector. The platform can be integrated into many applications, and the impact can range from reducing greenhouse gas emissions to protecting communities that are wildfire-prone. The core of the technology has a lower conductivity than aerogels. It also has a “near-perfect emissivity score” according to the company. The NanoTech ICP is integrated with base matrix carriers; building materials, coatings, and substrates, which gives the materials heat conservation, rejection, or containment properties.

By combining the ICP into an acrylic roof coating, NanoTech has created the Cool Roof Coat, which reflects sunlight and increases the material's heat resistance. This can lower indoor temperatures by 25 to 45°F in single-story buildings and reduce the carbon emissions of mid to low-rise buildings. This can potentially equal energy savings from 20 percent up to 50 percent, which would surpass the average 15 percent savings of traditional reflective only coatings.

“This technology will have a huge impact on supporting the region's aggressive climate initiatives, such as Saudi Arabia’s Green Initiative, aiming to reduce carbon emissions by 278 million tons annually by 2030,” Jameel Ahmed, managing director at TSSM, says in the release. “The regional efforts to enhance climate action and economic opportunities through substantial investments in green technologies and projects are evident, and we are proud to be offering a product that can make a difference.”

NanoTech says its coating maintains its effectiveness over time and doesn’t suffer UV degradation issues which are helpful, especially in extreme weather conditions workers and businesses face in regions like the Middle East.

Houston eco-focused materials startup launches initiative in Arizona

stay cool

Home to a persistent dry heat, Arizona is a prime market for energy-reducing tools and technologies — and one Houston company is jumping on the opportunity.

NanoTech Materials, which created the Cool Roof Coat that can extend a building's roof lifespan and reduce energy costs by seven to 15 percent, has announced a joint campaign with Cool Roof Coating Systems, a subsidiary of Tesson Roofing. Cool Roof Coating Systems will provide the installation of NanoTech's product, which is available nationwide.

"NanoTech products are designed to provide extraordinary heat rejection, and the team at Tesson is among the very best in the roof restoration market, which made a joint initiative in the extreme heat and intense Arizona sun a natural fit," Mike Francis, CEO and founder at NanoTech Materials, says in a news release. "As a direct-to-installer product, we rely on collaboration with highly qualified contractors. I am delighted at the founding of Cool Roof Coating Systems to bring a new level of sustainability to Arizona.

"Our vision at NanoTech is to transform sustainability in the built environment, starting with one of the biggest energy drains and sources of carbon emissions, one roof at a time," he adds.

The elastic, polymeric roof remediation solution is able to cut internal temperatures by 25°F to 30°F, which can be responsible for cutting carbon emissions by 76 tons annually in a 25,000-square-foot building, according to the company.

"Put simply, the heat-rejection performance of NanoTech Cool Roof Coat is so compelling that Tesson decided to form an Arizona-based company to tackle one of the hottest markets in the U.S. directly," Brett Tesson, president at Cool Roof Coating Systems, says in the release. "During my two decades in the roofing industry, NanoTech Cool Roof Coat is by far the most game-changing product for the roof restoration business because it allows us to coat, waterproof and protect, while adding unprecedented savings in HVAC cooling for our customers."

Last summer, NanoTech announced an oversubscribed funding round that brought onboard a handful of new investors. The details of the round were not disclosed, but the round was raised to help the company continue to roll out its product nationally.

Growing Houston startup announces latest funding to support national expansion

cool coating

A Houston startup that has developed an innovative coating material that can reduce energy consumption has raised fresh funding for its cross-country expansion.

NanoTech Inc. announced its latest funding news — an oversubscribed funding round that brings onboard a handful of new investors. The details of the round were not disclosed, but NanoTech did release that the round included participation from three institutional investors, two corporate-strategic investors, and seven family offices. These entities join initial investor, Austin-based Ecliptic Capital.

NanoTech's flagship product is a waterproof thermal coating, called the Nano Shield Cool Roof Coat, which began rolling out across the country this year. Not only does the product reduce energy costs for the building owner, but it reduces emissions as well.

"It's crucial to recalibrate the sustainability narrative – environmental responsibility and financial return can go hand in hand," says Mike Francis, CEO and co-founder of NanoTech, in a news release. “We’ve transformed the roof from a cost center to a savings source by reducing energy expenditures while also significantly shrinking the building's carbon footprint.”"The substantial decline in CO2 emissions and energy costs resulting from reduced reliance on HVAC systems is far more than a fringe benefit — it forms the cornerstone of our long-term strategy to lead the climate-resilient materials market. Beyond corporate objectives, it's a personal source of immense pride to foster a healthier planet for generations to come," Francis continues.

As the first selected company in Houston-based Halliburton Labs, NanoTech continues to benefit from the incubator's industrial scaling resources. Francis and Chief Commercial Officer Carrie Horazeck recently joined the Houston Innovators Podcast to discuss the impact their product is making as they roll out nationwide.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues.

Harris County officials seek more local control over data centers

data demands

Three Harris County officials are pushing for greater local control over the development and operation of data centers.

County Attorney Abby Kamin, County Commissioner Lesley Briones and County Commissioner Adrian Garcia recently called for action to give Harris County more power to regulate data centers.

As it stands now, Harris County “has little to no authority” over the construction of data centers, Briones said at a news conference. Harris County has 55 operating, under-construction, or planned data centers, according to a document filed with the county.

Briones outlined four steps being included in the Harris County commissioners’ exploration of potentially tighter local regulation of data centers:

Reviewing what Harris County can and cannot do regarding data centers
Creating a Harris County plan for the upcoming state legislative session aimed at granting more local control over data center construction and operations. State lawmakers would need to approve any changes in local control.
Establishing community “listening” sessions in Harris County about data centers
Notifying Harris County commissioners when a proposed data center seeks permits

Kamin noted Houston and Harris County lack zoning regulations, and the county’s 34 cities set their own zoning rules. Furthermore, she said, Texas Attorney General Ken Paxton has not issued a ruling on whether counties can impose a moratorium on development of data centers.

However, she said, “limited jurisdiction does not mean limited responsibility … New technology is arriving in our communities faster than our laws and institutions can keep up with, whether that’s data centers, AI or even drones.”

The effort by Kamin, Briones, and Garcia follows Gov. Greg Abbott’s recent statewide halt of new environmental and construction permits for data centers. State permitting is frozen until the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas complete their review of data centers.

Their initiative also comes amid growing public concern over the amount of electricity and water gobbled up by data centers, as well as residents’ own rising electric and water bills.

Houston-based CenterPoint Energy expects to connect 8 gigawatts of new data-center loads in the Houston area by 2029, with about 4 gigawatts to follow, Kamin said. That, she said, would significantly increase peak power demand.

“No industry should get to monopolize or run roughshod over residents, public safety, and our critical natural resources,” Kamin said.

That being said, Kamin and Briones stressed they take pride in Houston being the Energy Capital of the World and Texas being an economic powerhouse.

“This isn’t about being against technology or new technology, but growth has to go hand in hand with accountability,” Kamin said.

Garcia said he’s open to welcoming data centers as good corporate neighbors, but not without protecting the people who live near these projects.

“I’ll keep an open mind,” he said, “but I want to know what will ultimately be the benefit to the community. And right now, I need tools [to do that].”

Houston bio-based materials co. steps into new sustainable consumer products

a cleaner shoe

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.

Houston solar manufacturer expands facility, production capacity

houston expansion

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.
