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.

California company launches Tesla Megapack battery project in Houston area

power on

Oakland, California-based Nightpeak Energy announced earlier this month that its 150-megawatt battery storage project in Brazoria County, known as Bocanova Power, is now operating to address Houston’s peak capacity needs.

“This battery storage project will enhance grid reliability in the Alvin area while continuing to support integrating renewable energy,” Cary Perrin, president and CEO of the Northern Brazoria County Chamber of Commerce, said in a news release. “I believe we need energy storage now more than ever for its pivotal role in reducing strain on the grid while meeting fast-growing power demand in Texas and Brazoria County."

The project reached commercial operation in August, according to the release. The project utilizes Tesla's Megapack 2 XL battery storage system, and the facility operates under a long-term power purchase agreement with an undisclosed “investment-grade power purchaser.”

“Bocanova Power demonstrates the speed at which Nightpeak Energy is overcoming complex challenges to energize projects that support America's growing need for affordable, reliable, and secure energy,” Paris Hays, co-founder and CEO/CDO of Nightpeak Energy, added in the news release. “Unprecedented AI data center and manufacturing growth has only accelerated the need for these resources.”

Hays added in the release that the company has plans for more energy infrastructure projects in Texas and in the Western U.S.

Nightpeak Energy develops, owns and operates power plants that support the growing capacity needs of a decarbonized grid. It also owns and operates 240 MW of battery storage and natural gas generation facilities.

The company was founded in 2022 and backed by equity funding of up to $200 million from Dallas-based investment firm Energy Spectrum Capital.

Texas ranks low on most energy-efficient states report

by the numbers

Texas has room to improve when it comes to energy efficiency, recent data from WalletHub shows.

The personal finance website ranked Texas at No. 35 on the latest Most & Least Energy-Efficient States list. Texas improved by one spot on the 2025 report, after coming in at No. 36 last year.

The report measured and ranked the efficiency of auto energy and home energy consumption in the 48 U.S. mainland states based on data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration and the U.S. Department of Transportation – Federal Highway Administration.

Texas earned an overall score of 50.60. It was ranked No. 27 for home energy efficiency and No. 41 for auto efficiency. By comparison, No. 1-ranked Vermont earned a score of 85.30, ranking No. 2 for home energy and No. 6 for out energy.

The top five overall states included:

  • No. 1 Vermont
  • No. 2 California
  • No. 3 Washington
  • No. 4 New York
  • No. 5 Massachusetts

South Dakota earned the top rank for home energy efficiency, and Massachusetts earned the top rank for energy efficiency.

“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. 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," WalletHub analyst Chip Lupo said in the report. "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.”

According to the report, some progress is being made in increasing energy efficiency across the country. The U.S. Energy Information Administration expects 26 percent of electricity generation in 2026 will come from renewables. A number of them are being developed in the Houston area, including recent announcements like the Pleasure Island Power Collective in Port Arthur.

Still, Houston earned an abysmal ranking on WalletHub's greenest cities in the U.S. report earlier this year, coming in at No. 99 out of 100. Read more here.

Port Houston reports emissions progress as cargo volumes climb

greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools.

Port Houston aims to be carbon neutral by 2050.
