Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort.

Houston innovator on how health tech’s rise offers roadmap for climatetech growth

guest column

Over the past several decades, climate tech has faced numerous challenges, ranging from inconsistent public support to a lack of funding from cautious investors. While grassroots organizations and climate innovators have made notable efforts to address urgent environmental issues, we have yet to see large-scale, lasting impact.

A common tendency is to compare climate tech to the rapid advancements made in digital and software technology, but perhaps a more appropriate parallel is the health tech sector, which encountered many of the same struggles in its early days.

Observing the rise of health tech and the economic and political support it received, we can uncover strategies that could stabilize and propel climate tech forward.

Health tech's slow but steady rise

Health tech’s slow upward trajectory began in the mid-20th century, with World War II serving as a critical turning point for medical research and development. Scientists working on wartime projects recognized the broader benefits of increased research funding for the general public, and soon after, the Public Health Service Act of 1944 was passed. This landmark legislation directed resources toward eradicating widespread diseases, viewing them as a national economic threat. By acknowledging diseases as a danger to both public health and the economy, the government laid the groundwork for significant policy changes.

This serves as an essential lesson for climate tech: if the federal government were to officially recognize climate change as a direct threat to the nation’s economy and security, it could lead to similar shifts in policy and resource allocation.

The role of public advocacy and federal support

The growth of health tech wasn’t solely reliant on government intervention. Public advocacy played a key role in securing ongoing support. Voluntary health agencies, such as the American Cancer Society, lobbied for increased funding and spread awareness, helping to attract public interest and investment. But even with this advocacy, early health tech startups struggled to secure venture capital. VCs were hesitant to invest in areas they didn’t fully understand, and without sustained government funding and public backing, it’s unlikely that health tech would have grown as quickly as it has.

The lesson here for climate tech is clear: strong public advocacy and education are crucial. However, unlike health tech, climate tech faces a unique obstacle — there is still a significant portion of the population that either denies the existence of climate change or doesn’t view it as an immediate concern. This lack of urgency makes it difficult to galvanize the public and attract the necessary long-term investment.

Government support: A mixed bag

There have been legislative efforts to support climate tech, though they haven’t yet led to the explosive growth seen in health tech. For example, the Federal Technology Transfer Act of 1986 and the Bayh-Dole Act of 1980 gave universities and small businesses the rights to profit from their innovations, including climate-related research. More recently, the Inflation Reduction Act (IRA) of 2022 has been instrumental in advancing climate tech by creating opportunities to build projects, lower household energy costs, and reduce greenhouse gas emissions.

Despite this federal support, many climate tech companies are still struggling to scale. A primary concern for investors is the longer time horizon required for climate startups to yield returns. Scalability is crucial — companies must demonstrate how they will grow profitably over time, but many climate tech startups lack practical long-term business models.

As climate investor Yao Huang put it, “At the end of the day, a climate tech company needs to demonstrate how it will make money. We can apply political pressure and implement governmental policies, but if it is not profitable, it won’t scale or create meaningful impact.”

The public’s role in scaling climate tech

Health tech’s success can largely be attributed to a combination of federal funding, public advocacy, and long-term investment from knowledgeable VCs. Climate tech has federal support in place, thanks to the IRA, but is still lacking the same level of public backing. Health tech overcame its hurdles when public awareness about the importance of medical advancements grew, and voluntary health agencies helped channel donations toward research and innovation.

In contrast, climate nonprofits like Cool Earth, Environmental Defense Fund, and Clean Air Task Force face a severe funding shortfall. A 2020 study revealed that climate nonprofits aiming to reduce greenhouse gas emissions only received $2 billion in donations, representing just 0.4% of all philanthropic funding. Without greater public awareness/sense of urgency and financial support, these groups cannot effectively advocate for climate tech startups or lobby for necessary policy changes. This type of philanthropic funding is also known as ‘catalytic capital’ or ‘impact-first-capital’. Prime Impact Fund is one such fund that does not ‘view investments as concessionary on return’. Rather their patient and flexible capital allows support of high risk, high-reward ventures.

A path forward for climate tech

The most valuable insight from health tech’s growth is that government intervention, while critical, is not enough to guarantee the success of an emerging sector. Climate tech needs a stronger support system, including informed investors, widespread public backing, and nonprofits with the financial resources to advocate for industry-wide growth.

If we can channel the same sense of urgency and public commitment toward climate change as we did for health crises in the past, climate tech could overcome its current obstacles.The future of climate tech depends not just on government policies, but on educating the public, rallying financial support, and building a robust infrastructure for long-term growth.

Houston climatetech incubator brings in new automation tools for startup use

Houston’s Greentown Labs announced new resources and equipment for its members thanks to two corporate partnerships.

Greentown Houston is now home to new tools from Emerson and Puffer to help members implement strong foundations for access to contextualized data.

Automation is the theme with the latest resources, as the process assists with a startup's journey to “standardization and scalability” according to a news release from Greentown Labs. Members will have access to these two units and platforms. The DeltaV Automation Platform is a data-driven decision-making resource that aims to improve operational performance while reducing risks, costs, and downtime. It integrates real-time analytics, advanced automation solutions, sophisticated control systems, and lifecycle services.

Puffer-Sweiven is a localized, single point of contact for sales, service, and applied engineering for Emerson Automation Solutions in the Texas Gulf Coast and Central Texas area with the capabilities to combine with other members in North America to leverage global reach and technologies. Puffer is an Emerson Impact Partner.

With access to the two units, Greentown Labs member companies can further explore easy-to-use, integrated-by-design DeltaV Distributed Control System. With the system, companies and members can better scale new technologies into pilot scale, optimize processes for high quality products, and implement a smart foundation for access to contextualized data. Global ROC is one company that is already utilizing the new resources at Greentown Labs.

“Our member Global ROC, which is developing a solution for cooling tower systems that reduces chemical consumption, saves water, and reduces energy costs, plans to use the system in two ways,” Global ROC CEO Ely Trujillo said to Greentown Labs via LinkedIn.

The startup will be able to create a control method that can be applied to future projects by using and comparing Global ROC’s products with the Delta V’s advanced function blocks. Trujilloalso plans to train team members to set up a Proportional Integral Derivative (PID) controller. The PID involves building a lab test box that connects to the DeltaV’s CHARM modules to control a process to a temperature by varying amperage through the DeltaV’s PID controller.

As part of the 3-year kickoff of the Texas Exchange for Energy and Climate Entrepreneurship (TEX-E), Greentown Labs also celebrated 87 Texas students from The University of Texas at Austin, Texas A&M University, University of Houston, Rice University, Prairie View A&M University, and the Massachusetts Institute of Technology have been accepted into this year's Fellowship. The students will gain access to hands-on experiences including internships, pitch competitions, entrepreneurship bootcamps, courses, and conferences geared to help the climate and energy-transition innovation field.

In

March, Greentown Labs and Browning the Green Space were named the newest accelerator for the Advancing Climatetech and Clean Energy Leaders Program, or ACCEL. The seven selected startups will have a year-long curated curriculum, incubation at Greentown's two locations, and a non-dilutive $25,000 grant.

Houston geothermal startup secures $244M in funding round led by energy corporate

fresh funding

An Oklahoma-based shale oil and gas leader has backed Fervo Energy's latest round of funding, supporting the startup's geothermal technology yet again.

Fervo announced its latest round of funding this week to the tune of $244 million. The round was led by Devon Energy, a company that's previously backed the startup.

“Demand for around-the-clock clean energy has never been higher, and next-generation geothermal is uniquely positioned to meet this demand,” Tim Latimer, Fervo CEO and co-founder, says in a news release. “Our technology is fully derisked, our pricing is already competitive, and our resource pipeline is vast. This investment enables Fervo to continue to position geothermal at the heart of 24/7 carbon-free energy production.”

Founded in 2017, Fervo provides carbon-free energy through development of next-generation geothermal power. The company has recently reported its success at its Cape Station project, a400 MW project in Beaver County, Utah, as well as at its full-scale commercial pilot, Project Red, in northern Nevada and made possible through a 2021 partnership with Google.

Galvanize Climate Solutions, John Arnold, Liberty Mutual Investments, Marunouchi Innovation Partners, Mercuria, and Mitsubishi Heavy Industries also contributed to the round with existing investors Capricorn’s Technology Impact Fund, Congruent Ventures, DCVC, Elemental Excelerator, Helmerich & Payne, and Impact Science Ventures.

“The energy trilemma is one of the defining global challenges of our time; how can we generate power that is affordable, reliable, and clean,” Houstonian John Arnold, founder of Centaurus Capital and co-chair of Arnold Ventures, says in the release. “Fervo has transformed geothermal into a scalable carbon-free resource ready to meet the moment.”

The fresh funding, according to the company, will go toward Fervo’s work in Cape Station, that is slated to begin delivering clean electricity to the grid in 2026.

“Fervo’s approach to geothermal development leverages leading-edge subsurface, drilling, and completions expertise and techniques Devon has been honing for decades,” David Harris, chief corporate development officer and executive vice president at Devon, says in the release. “We look forward to deepening our partnership with Fervo to capture the full value of Fervo’s first-mover advantage in geothermal and the adjacencies to Devon’s core business.”

In 2022, Fervo raised a $138 million series C round to support the completion of power plants in Nevada and Utah and evaluate new projects in California, Idaho, Oregon, Colorado, and New Mexico, as well as in other countries. This latest investment brings the company's total funds raised to $431 million since its inception in 2017, according to Crunchbase.

5 tips for people looking to expand their career into climate tech, according to this Houston expert

guest column

If hard times build strong people, then extreme weather events build strong climate tech ecosystems. Nobody knows this conventional wisdom better than Houston.

The past six years alone have seen the second costliest natural disaster in United States history (Hurricane Harvey), the longest power outage in Texas history (Winter Storm Uri), and this June, a heat wave that pushed the ERCOT power grid to record levels.

Combine our ever more volatile climate with a post-COVID-19 reckoning of what it means to work for what you believe in, and you get a recipe for the most significant workforce shift the world has ever seen. This workforce shift rules in favor of climate tech, and it will largely target those who’ve grown up, come of age and started their careers in the midst of this increasing volatility. Climate tech will no longer be considered a standalone industry; it will be baked into all existing industries, and those that don’t accept it will die.

I’m proud to be a climate optimist, but I’m also a realist. The truth is no matter what we do, our volatile climate is going to get worse before it gets better. But if extreme weather events build strong climate tech ecosystems, I can live with that.

To students and young professionals considering a jump into climate tech: There is no better place to be right now. Here are five things to keep in mind as you make that jump.

1. Meet as many people from diverse backgrounds working on as many different things as you can. You will likely feel awkward at first, especially if you don’t naturally gravitate toward conferences and happy hours. At the risk of sounding trite, just treat every stranger like a friend you haven’t met yet. Some of us could probably use more friends anyway.

2. The advice in the self-help book How to Win Friends and Influence People, originally published in 1936, is timeless. Possibly the most useful (and most obvious) point is this: Remember that a person’s name is to that person the sweetest and most important sound in any language. Whenever possible, repeat your new friends’ names when you meet them. Especially if you’re seeking a business development, sales or other external-facing role, perfecting this point should be your Holy Grail.

3. Depending on how new you are to energy and climate tech, you’ll hear lots of unfamiliar lingo. Ask questions, take note of what you still don’t get, and do your best to fill in the gaps on the side. Eventually, acronyms will become your best friend. For example: Have you seen what the ITC and the PTC from the IRA will do to the LCOE of PV according to NREL? IYKYK.

4. Coachability is key. You may feel like you’re getting rejected 99 percent of the time, but the way you respond to and learn from those experiences will ensure the other one percent makes all the difference. At the end of the day, climate tech is so vast that it’s impossible to become an expert in everything, and that’s okay. We may not know what’s going on 70 percent of the time, but I’ll take a .300 batting average any day.

5. It may be impossible to become an expert in everything, but you should proactively learn as much as you can, especially given how quickly the ecosystem is expanding. If you’re not embarrassed by how little you knewone year ago, two years ago or even five years ago, then you’re probably not trying hard enough.

These are only five of my takeaways over the past few years and I’ll be the first to admit that I have a long way to go in implementing them. In a way, that’s what makes this journey what it is. I just can’t wait to see what we build.

TMC lands $3M grant to launch cancer device accelerator

cancer funding

A new business accelerator at Houston’s Texas Medical Center has received a nearly $3 million grant from the Cancer Prevention and Research Institute of Texas.

The CPRIT grant, awarded to the Texas Medical Center Foundation, will help launch the Accelerator for Cancer Medical Devices. The accelerator will support emerging innovators in developing prototypes for cancer-related medical devices and advancing them from prototype to clinical trials.

“The translation of new cancer-focused precision medical devices, often the width of a human hair, creates the opportunity to develop novel treatments for cancer patients,” the accelerator posted on the CPRIT website.

Scientist, consultant, and entrepreneur Jason Sakamoto, associate director of the TMC Center for Device Innovation, will oversee the accelerator. TMC officials say the accelerator builds on the success of TMC Innovation’s Accelerator for Cancer Therapeutics.

Each participant in the Accelerator for Cancer Medical Devices program will graduate with a device prototype, a business plan, and a “solid foundation” in preclinical and clinical strategies, TMC says. Participants will benefit from “robust support” provided by the TMC ecosystem, according to the medical center, and “will foster innovation into impactful and life-changing cancer patient solutions in Texas and beyond.”

In all, CPRIT recently awarded $27 million in grants for cancer research. That includes $18 million to attract top cancer researchers to Texas. Houston institutions received $4 million for recruitment:

  • $2 million to the University of Texas MD Anderson Cancer Center to recruit Rodrigo Romero from Memorial Sloan Kettering Cancer Center in New York City
  • $2 million to MD Anderson to recruit Eric Gardner from Weill Cornell Medicine in New York City

A $1 million grant also went to Baylor College of Medicine researcher Dr. Akiva Diamond. He is an assistant professor at the medical college and is affiliated with Baylor’s Dan L. Duncan Comprehensive Cancer Center.

Musk’s SpaceX spends $17B to acquire spectrum licenses from EchoStar

SpaceX Update

Elon Musk’s SpaceX has reached a deal worth about $17 billion with EchoStar for spectrum licenses that it will use to beef up its Starlink satellite network.

The deal for EchoStar’s AWS-4 and H-block spectrum licenses includes up to $8.5 billion in cash and up to $8.5 billion in SpaceX stock. SpaceX will make approximately $2 billion in cash interest payments on EchoStar debt through November 2027.

SpaceX and EchoStar will enter into a long-term commercial agreement which will allow EchoStar’s Boost Mobile subscribers to access SpaceX’s next generation Starlink Direct to Cell service.

Shares of EchoStar surged 19% before the market opened Monday.

Last month AT&T said that it will spend $23 billion to acquire wireless spectrum licenses from EchoStar, a significant expansion of its low- and mid-band coverage networks.

EchoStar said that it anticipates that the AT&T deal and the SpaceX transaction will resolve recent inquiries from the Federal Communications Commission about the rollout of 5G technology in the U.S. The FCC had been calling for hearings on whether Echostar was properly using the spectrum that it is now selling, and its efforts to make 5G more available to communities.

EchoStar said Monday that it will use the proceeds from the sale partly to pay down debt. Current operations of Dish TV, Sling and Hughes will not be impacted, the company said.
