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.

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”
