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.

Houston’s Fervo Energy amasses $12B backlog of orders

q3 results

Houston-based geothermal power company Fervo Energy saw a 65 percent spike in purchase orders during the third quarter.

During Fervo’s third-quarter earnings call, Tim Latimer, co-founder, chair, president and CEO, said the company had a $11.9 billion backlog of orders, up from $7.2 billion in the previous quarter.

Those numbers didn’t translate to robust financial results in the third quarter, though. It closed the quarter with an operating loss of $43 million on revenue of just $116,000.

Beyond the billions of dollars in signed purchase agreements, Fervo is in talks with prospective customers in the utility, industrial data-center sectors, Latimer said. About half the potential customers are in the data-center sector, 35 percent in the utility sector and 15 percent in the industrial sector.

Latimer said the broad-based demand reflected by the backlog and the discussions with potential customers reinforces the critical need for reliable, readily available power.

“Our approach to power delivery will continue to blend front-of-the-meter and behind-the-meter development,” he said. “Grid-connected assets remain the foundation, though behind-the-meter gives customers a faster path to power when transmission time lines lag their need.”

Front-of-the-meter refers to power plants, utility-scale solar and wind farms, large grid batteries, and transmission and distribution infrastructure. Behind-the-meter assets sit on the customer side of the meter, such as backup generators and EV chargers at homes, businesses, factories and other everyday places.

The order backlog isn’t Fervo’s only recent milestone. In late September, the company’s Cape Station geothermal plant in Utah started delivering its first utility-scale geothermal power to the grid. The plant is producing about 33 megawatts of power.

Earlier in September, Fervo signed a 15-year deal to supply about 396 megawatts of power for Google data centers. The power will be delivered in four 99-megawatt batches. The company filed its $1.89 billion IPO this spring.

3 Houston incubators supporting hard tech, energy transition, and beyond

Meet The Finalists

It takes a village to launch a business. That's where Houston's network of incubators and accelerators can step in, providing the resources, mentorship and community needed to push a fledgling company forward.

As part of InnovationMap's 2026 Houston Innovation Awards, the Incubator/Accelerator of the Year category honors a local organization that is championing and fueling the growth of Houston startups.

Three incubators and accelerators have been named finalists for the 2026 award. They support startups ranging from hard tech companies to food and youth concepts.

Read more about these organizations below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced in 2024, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its third Houston cohort this summer.

The two-year program graduated its first class of Houston fellows in 2026 and saw its first alumni IPO from Houston-based Fervo Energy, which previously participated in a Berkley cohort. Nationally, it has supported 346 fellows and 276 companies since 2015. Those companies have raised more than $6 billion in follow-on funding, according to Activate. In Houston, it has supported Houston startups like energy transition leaders Solidec and FlowCellutions. Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with members spanning 72 countries. Launched in 2018, Impact Hub Houston says its membership tripled by the beginning of 2026. This year brought major milestones for the community, including the launch of its Ideas to Impact Accelerator, which supported 11 founders across the health, education, food systems, civic technology and workforce development sectors. It also received funding from more than 20 international Impact Hubs to develop SYNC, a collaboration platform that 25 Impact Hubs across five continents have committed to pilot. The organization has worked with local startups including Myoviva Health, The Change Lab and INNERVERSE Inc.

MarMo Innovation

Galveston-based business incubator MarMo Innovation is focused on removing barriers to entrepreneurship. It aims to provide affordable space, education, mentorship, market access, connections and real-world opportunities that help entrepreneurs move from idea to launch to sustainable growth. The "industry-agnostic" incubator was founded in 2022 and is led by Executive Director Erica Delgadillo.

This year, the organization moved from primarily serving as a coworking and community space into a more comprehensive entrepreneurial incubator by expanding its MarMo Market, MarMo Market Jr. and Lunch LineUp programs. A major focus for MarMo is food entrepreneurship. It is developing an Incubator Kitchen, which MarMo says will support programs like its Cottage to Commercial Bootcamp and Food Biz 101. The organization also expanded its board this year and says it is diversifying its revenue through memberships, events, markets, equipment and space rentals, sponsorships, grants and new entrepreneurial programming.

Sage Geosystems taps Halliburton to advance Nevada geothermal project

power partnership

Houston-based Sage Geosystems has selected oil and gas powerhouse Halliburton to provide cementing and stimulation services at its enhanced geothermal project in Nevada known as Project Vector.

“Our technology and experience will support Sage as it advances its geopressured geothermal technology,” Shawn Skobel, vice president at Halliburton, said in a news release.

Halliburton will provide Sage with technical modeling, engineering design, and field execution support as part of its specialized cementing and stimulation services at Project Vector at Ormat Technologies' Blue Mountain geothermal power plant. Sage announced the location of the geothermal project in September.

At the time, Sage said it expected to begin drilling the first well at Project Vector this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

The project will use Sage’s enhanced geothermal systems (EGS) method in a two-well system to convert geothermal heat into electricity. The project aims to help meet industrial and residential demand, especially as data centers strain energy grids.

Founded in 2020, Sage has raised $159 million across three funding rounds. Its technology aims to reach Earth’s natural heat source deep underground for more consistent power generation and utilizes engineered subsurface reservoirs to minimize water and energy losses and increase net power output. Through the process, Sage says it can enable reliable, 24/7 power generation.

“One of the keys to scaling next-generation geothermal is combining innovative subsurface technology with the proven capabilities and execution of the oil and gas industry,” Jason Peart, Chief Operating Officer of Sage Geosystems, added in the news release. “Halliburton brings decades of experience in well integrity and reservoir stimulation, two critical components of our development approach. By selecting an established industry leader, we are strengthening our ability to execute Project Vector and demonstrate that Sage’s technology can be replicated and deployed commercially across a broad range of geologies.”

Sage is building off prior success of its South Texas SMECI facility, which began operations in August. Project Vector supports Sage’s growing commercial pipeline, which includes a 150-megawatt geothermal power agreement with Meta.
