3 Houston sustainability startups score prizes at Rice University pitch competition

seeing green

A group of Rice University student-founded companies shared $100,000 of cash prizes at an annual startup competition — and three of those winning companies are focused on sustainable solutions.

Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge, hosted by Rice earlier this month, named its winners for 2024. HEXASpec, a company that's created a new material to improve heat management for the semiconductor industry, won the top prize and $50,000 cash.

Founded by Rice Ph.D. candidates Tianshu Zhai and Chen-Yang Lin, who are a part of Lilie’s 2024 Innovation Fellows program, HEXASpec is improving efficiency and sustainability within the semiconductor industry, which usually consumes millions of gallons of water used to cool data centers. According to Rice's news release, HEXASpec's "next-generation chip packaging offer 20 times higher thermal conductivity and improved protection performance, cooling the chips faster and reducing the operational surface temperature."

A few other sustainability-focused startups won prizes, too. CoFlux Purification, a company that has a technology that breaks down PFAS using a novel absorbent for chemical-free water, won second place and $25,000, as well as the Audience Choice Award, which came with an additional $2,000.

Solidec, a company that's working on a platform to produce chemicals from captured carbon, and HEXASpec won Outstanding Achievement in Climate Solutions Prizes, which came with $1,000.

The NRLC, open to Rice students, is Lilie's hallmark event. Last year's winner was fashion tech startup, Goldie.

“We are the home of everything entrepreneurship, innovation and research commercialization for the entire Rice student, faculty and alumni communities,” Kyle Judah, executive director at Lilie, says in a news release. “We’re a place for you to immerse yourself in a problem you care about, to experiment, to try and fail and keep trying and trying and trying again amongst a community of fellow rebels, coloring outside the lines of convention."

This year, the competition started with 100 student venture teams before being whittled down to the final five at the championship. The program is supported by Lilie’s mentor team, Frank Liu and the Liu Family Foundation, Rice Business, Rice’s Office of Innovation, and other donors

“The heart and soul of what we’re doing to really take it to the next level with entrepreneurship here at Rice is this fantastic team,” Peter Rodriguez, dean of Rice Business, adds. “And they’re doing an outstanding job every year, reaching further, bringing in more students. My understanding is we had more than 100 teams submit applications. It’s an extraordinarily high number. It tells you a lot about what we have at Rice and what this team has been cooking and making happen here at Rice for a long, long time.”

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.
