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.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.

7 Houstonians from energy sector make Forbes list of richest Americans

Rich List

The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston. Seven of them have ties to the energy industry.

Oil tycoon Jeffery Hildebrand, 67, now reigns as the No. 1 richest Houstonian, the 9th richest Texan, and the 88th richest person in America for 2026. Hildebrand's net worth has surged $4.7 billion since last year, bringing his current net worth to $14.7 billion. He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Kinder Morgan chairman Richard Kinder is the No. 2 richest in Houston. Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list. His net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Houston pipeline heir Randa Duncan Williams ranks 124th on the list with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.

Energy exploration chief executive George Bishop of GeoSothern Energy ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Here's how the rest of Houston's billionaires, outside of the energy industry, ranked on this year's list:

  • Toyota mega-dealer Dan Friedkin, 61, is the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.
  • Hospitality honcho Tilman Fertitta, 69, has a net worth of $12.3 billion and is the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.
  • Texans owner and CEO Cal McNair, 64, ranks as the 218th richest person in America with an estimated net worth of $7.7 billion.
