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. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

Why this entrepreneur believes Houston should lead resilience technology alongside the energy transition

tune in

When it comes to developing resilience technology, Houston startup founder Ali Mostafavi knows he's in the right place.

Mostafavi, a civil and environmental engineering professor at Texas A&M University, co-founded Resilitix.AI two years ago, and with the help of his lab at A&M, has created a platform that brings publicly available data into AI algorithms to provide its partners near-real time information in storm settings.

"We are very excited that our company is Houston based," he says on the Houston Innovators Podcast. "We should not be just ground zero of disasters. We have to also be ground zero for solutions as well. I believe Houston should be the hub for resilience tech innovation as it is for energy transition.

"I think energy transition, climatetech, energy tech, and disaster tech go hand in hand," Mostafavi continues. "I feel that we are in the right place."

Earlier this month, Mostafavi got an unexpected chance to pilot his company's data-backed and artificial intelligence-powered platform — all while weathering one of Houston's most impactful storms.

As Hurricane Beryl came ashore with Houston on its path, Mostafavi says he had the opportunity to both test his technology and provide valuable information to his community during the storm.

"We were in the process of fine tuning some of our methods and algorithms behind our technology," Mostafavi says. "When disasters happen, you go to activation mode. We put our technology development and R&D efforts on hold and try to test our technology in an operational setting."

The platform provides its partners — right now, those include local and state organizations and emergency response teams — information on evacuation reports, street flooding, and even damage sustained based on satellite imagery. Mostafavi says that during Beryl, users were wondering how citizens were faring amid rising temperatures and power outages. The Resilitix team quickly pivoted to apply algorithms to hospital data to see which neighborhoods were experiencing high volumes of patients.

"We had the ability to innovate on the spot," Mostafavi says, adding that his own lack of power and internet was an additional challenge for the company. "When an event happens, we start receiving requests and questions. ... We had to be agile and adapt our methods to be responsive. Then at the same time, because we haven't tested it, we have to verify that we are confident (in the information we provide)."

On the episode, Mostafavi shares how Hurricane Harvey — which occurred shortly after Mostafavi moved to Houston — inspired the foundation of Resilitix, and he also explains how he plans to grow and scale the business.

With $200M raised last year, Houston cleans up on new report tracking climatetech funding

We're No. 5

Climatech funding for Houston-area startups crept toward the $200 million mark in 2023 — putting it ahead of Dallas-Fort Worth, Austin, and several other major metro areas and making it a standout among U.S. climatech hubs.

Last year, the Houston area collected $199.94 million in climatech funding across 14 deals, according to PitchBook data analyzed by Revolution Growth, a venture capital firm based in Washington, D.C.

“With its deep-rooted energy sector, Houston is an attractive HQ for companies innovating within renewable energy, carbon capture, and emissions reduction,” Revolution says. “Partnerships with oil and gas companies also provide unique collaboration opportunities for climate tech startups, accelerating market adoption and helping companies achieve scale quickly.”

Los Angeles led the climatech funding list at $544.62 million, followed by No. 2 Denver, No. 3 D.C., No. 4 Seattle, and No. 5 Houston. In 12th place was Dallas-Fort Worth ($30.55 million). Austin claimed the No. 15 spot ($13.38 million).

“While traditional coastal tech hubs still hold considerable influence, dozens of [climatech] clusters are emerging between them,” says Revolution.

In its new report on America’s top climatech hubs, Revolution cites three Houston startups to watch:

  • Buildforce, a platform for workers in the electrical trades
  • Fervo Energy, a supplier of carbon-free energy through geothermal projects
  • Solugen, a developer of bio-based chemicals that replace traditional petroleum-based products

Houston energy startup CEO calls for tech players to join the climate fight

guest column

In 2022, over 100,000 workers were laid off from major technology companies in an economic slowdown, leaving many people wondering what the future holds. There’s a bright spot, however. These closed doors create an opening for individuals to begin a new career in climate tech, especially as these former tech employees possess skills needed to find and develop novel ways to innovate.

The story of a techie turning to climate isn’t new by any means. For example, Alex Roetter was the former head of engineering at Twitter but later pivoted to climate tech, becoming a managing director and general partner of Moxxie Ventures and the founder of Terraset, a nonprofit focused on funding high-quality carbon removal. Raj Kapoor followed a similar path as he now serves as the co-founder and managing partner of Climactic, a venture capital firm solving climate-related issues using technology, after working as Lyft’s chief strategy officer.

What’s unique now is that the climate tech industry is ready for it – public and private companies have made climate pledges that need industry-disrupting tech solutions, and there is federal, state, and private funding that are backing these solutions up.

When I started out in the energy industry nearly a dozen years ago, there was no such thing as a career in climate tech. Shortly after the 2008 financial crisis, I found a job at a firm backed by smart investors who saw through the noise and realized renewable energy investments are some of the most stable and predictable ways to earn financial returns. Now that Wall Street recognizes investments in climate-related industries as the best way to achieve their long term financial obligations, we’ve seen nearly every company realize they don’t have an economic future unless they also focus on climate results.

We used to say, “every company will become a tech company.” We’re now moving towards a world where “every company is a climate company.” And that is creating opportunities throughout the economy for people to contribute their skills and support their families while building something that actually matters.

Why climate tech is a safe bet

Taking a career twist into climate tech is a safe bet for a few reasons. The first is, unfortunately and obviously, the fact that climate change is getting worse. Between extreme weather events becoming more frequent around the world and the past eight years becoming the hottest on record, there is a huge need for climate mitigation solutions in every sector. What’s more, with the Earth’s population hitting eight billion, we will need to scale technology that addresses challenges like grid instability and food security, as governments try to balance resources. In fact, the Biden-Harris Administration announced $13B of programs to expand the U.S.’s power grid.

To tackle climate change, federal, state, and private sector capital investment in climate tech is at an all time high. As leaders pledge to reach net zero by 2050, investments and commitments to accelerate solutions to decarbonize the planet and make it more sustainable are being prioritized. Last year, there was a whopping $26.8 billion poured into climate tech. In five years, the climate tech market is estimated to near $1.4 trillion and with new energy plans in the Inflation Reduction Act announced earlier this year, investors are heavily influenced in funding the climate tech space.

An easier career shift

A switch to climate tech can be daunting, but it’s not just hard sciences like chemistry and materials engineering. It’s software engineers, social media savvants, and sales specialists. We have employees who have worked at places such as Google and Square come and support us with building our backend tech stack and consumer app. One of our tech leaders is a famous author, having written several books about coding in Django.

We’ve also recently heard about the “great resignation” over the past couple of years, but I think that framing is wrong. I think it's a “great reconsideration”. The reality is, for most of us on a given day, we spend more of our waking hours at work than any other activity. People need purpose — lack of purpose is the biggest reason for burnout. In fact not only have we not been impacted by the “great resignation” that many other firms have been, but we’ve actually received over tens of thousands of applications for our open roles in the past year alone. The career pivot to something meaningful is happening, and it’s happening today.

For example, one of our data engineers graduated from MIT and used to work in Houston as a chemical engineer — after some reskilling, she’s now a data engineer for our Kraken Technologies platform. Another one of our colleagues worked in the traditional marketing space and has transitioned over to climate tech to lead our global marketing. The climate industry needs as many out-of-the-box people as possible to draw new perspectives for reaching climate goals and getting us closer to a clean future.

Not sure where to start? There are several resources dedicated to onboarding people into the climate tech world. Some of my favorite are:

  • Climatebase: this platform is essentially a LinkedIn for climate tech — people can discover climate jobs and learn how they can transition to the space.
  • Climate Change Careers: founded in 2020, this site features job postings, educational opportunities, and information about switching to a climate-focused career.
  • Climate Draft: a member supported coalition comprising climate tech startups and venture capitalists who aim to bring more top talent, investment and commercial opportunities to the table.
  • ClimatEU: a leading resource for climate jobs and employers in Europe consisting of job postings, and opportunities for companies to find additional investment opportunities.
  • Climate People: a platform dedicated to mobilizing a workforce transition towards climate careers.

My inbox is also always open to people interested in joining the energy end of the world — whether it’s to talk about different openings at Octopus Energy, discuss how your expertise transfers to climate tech, or just to say hello.

CenterPoint and partners launch AI initiative to stabilize the power grid

AI infastructure

Houston-based utility company CenterPoint Energy is one of the founding partners of a new AI infrastructure initiative called Chain Reaction.

Software companies NVIDIA and Palantir have joined CenterPoint in forming Chain Reaction, which is aimed at speeding up AI buildouts for energy producers and distributors, data centers and infrastructure builders. Among the initiative’s goals are to stabilize and expand the power grid to meet growing demand from data centers, and to design and develop large data centers that can support AI activity.

“The energy infrastructure buildout is the industrial challenge of our generation,” Tristan Gruska, Palantir’s head of energy and infrastructure, says in a news release. “But the software that the sector relies on was not built for this moment. We have spent years quietly deploying systems that keep power plants running and grids reliable. Chain Reaction is the result of building from the ground up for the demands of AI.”

CenterPoint serves about 7 million customers in Texas, Indiana, Minnesota and Ohio. After Hurricane Beryl struck Houston in July 2024, CenterPoint committed to building a resilient power grid for the region and chose Palantir as its “software backbone.”

“Never before have technology and energy been so intertwined in determining the future course of American innovation, commercial growth, and economic security,” Jason Wells, chairman, president, and CEO of CenterPoint added in the release.

In November, the utility company got the go-ahead from the Public Utility Commission of Texas for a $2.9 billion upgrade of its Houston-area power grid. CenterPoint serves 2.9 million customers in a 12-county territory anchored by Houston.

A month earlier, CenterPoint launched a $65 billion, 10-year capital improvement plan to support rising demand for power across all of its service territories.

ERCOT approves $9.4B project to improve grid, meet data center demand

power project

The Electric Reliability Council of Texas, which manages the electric grid for 90 percent of Texans, is undertaking a $9.4 billion project to improve the reliability and efficiency of statewide power distribution. The initiative comes as ERCOT copes with escalating demand for electricity from data centers and cryptocurrency-mining facilities.

The project, approved Dec. 9 by ERCOT’s board, will involve building a 1,109-mile “super highway” of new 765-kilovolt transmission lines. One kilovolt equals 1,000 volts of electricity.

According to the Hoodline Dallas news site, the $9.4 billion project represents the five- to six-year first phase of ERCOT’s Strategic Transmission Expansion Plan (STEP). Hoodline says the plan, whose price tag is nearly $33 billion, calls for 2,468 miles of new 765-kilovolt power lines.

STEP will enable ERCOT to “move power longer distances with fewer losses,” Hoodline reports.

Upgrading the ERCOT grid is a key priority amid continued population growth in Texas, along with the state’s explosion of new data centers and cryptocurrency-mining facilities.

ERCOT says about 11,000 megawatts of new power generation capacity have been added to the ERCOT grid since last winter.

But in a report released ahead of the December board meeting, ERCOT says it received 225 requests this year from large power users to connect to its grid — a 270 percent uptick in the number of megawatts being sought by mega-users since last December. Nearly three-fourths (73 percent) of the requests came from data centers.

Allan Schurr, chief commercial officer of Houston-based Enchanted Rock, a provider of products and services for microgrids and onsite power generation, tells Energy Capital that the quickly expanding data center industry is putting “unprecedented pressure” on ERCOT’s grid.

“While the state has added new generation and transmission capacity, lengthy interconnection timelines and grid-planning limitations mean that supply and transmission are not keeping pace with this rapid expansion,” Schurr says. “This impacts both reliability and affordability.”

For families in Texas, this could result in higher energy bills, he says. Meanwhile, critical facilities like hospitals and grocery stores face a heightened challenge of preventing power outages during extreme weather or at other times when the ERCOT grid is taxed.

“I expect this trend to continue as AI and high-density computing grow, driving higher peak demand and greater grid variability — made even more complex by more renewables, extreme weather and other large energy users, like manufacturers,” Schurr says.

According to the Pew Research Center, data centers accounted for 4 percent of U.S. electricity use in 2024, and power demand from data centers is expected to more than double by 2030. Data centers that support the AI boom make up much of the rising demand.

In September, RBN Energy reported more than 10 massive data-center campuses had been announced in Texas, with dozens more planned. The Lone Star State is already home to roughly 400 data centers.

“Texas easily ranks among the nation’s top states for existing data centers, with only Virginia edging it out in both data-center count and associated power demand,” says RBN Energy.

Federal judge strikes Trump order blocking wind energy development

wind win

In a win for clean energy and wind projects in Texas and throughout the U.S., a federal judge struck down President Donald Trump’s “Day One” executive order that blocked wind energy development on federal lands and waters, the Associated Press reports.

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s executive order from Jan. 20, declaring it unlawful and calling it “arbitrary and capricious.”

The challenge was led by a group of state attorneys general from 17 states and Washington, D.C., which was led by New York Attorney General Letitia James. The coalition pushed back against Trump's order , arguing that the administration didn’t have the authority to halt project permitting, and that efforts would critically impact state economies, the energy industry, public health and climate relief efforts.

White House spokesperson Taylor Rogers told the Associated Press that wind projects were given unfair treatment during the Biden Administration and cited that the rest of the energy industry suffered from regulations.

According to the American Clean Power Association, wind is the largest source of renewable energy in the U.S. It provides 10 percent of the electricity generated—and growing. Texas leads the nation in wind electricity generation, accounting for 28 percent of the U.S. total in 2024, according to the U.S. Energy Information Administration.

Several clean-energy initiatives have been disrupted by recent policy changes, impacting Houston projects.

The Biden era Inflation Reduction Act’s 10-year hydrogen incentive was shortened under Trump’s One Big Beautiful Bill Act, prompting ExxonMobil to pause its Baytown low-carbon hydrogen project. That project — and two others in the Houston region — also lost federal support as part of a broader $700 million cancellation tied to DOE cuts.

Meanwhile, Texas House Democrats have urged the administration to restore a $250 million Solar for All grant that would have helped low-income households install solar panels.
