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.

Port Houston reports emissions progress as cargo volumes climb

greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools.

Port Houston aims to be carbon neutral by 2050.

7 innovative startups fueling the energy transition in Houston

Meet the Innovators

Houston has long been touted as the energy capital of the world, and it's now it's also a leading player in the energy transition — home to numerous startups and innovators working toward a cleaner future.

As part of the 2025 Houston Innovation Awards, presented by InnovationMap, the Energy Transition Business category honors innovative startups that are providing solution within renewables, climatetech, clean energy, alternative materials, circular economy, and more.

Seven energy transition companies have been named finalists for the 2025 award. They range from a spinoff stimulating subsurface hydrogen from end-of-life oil fields to a company converting prickly pear cactus biogas into energy.

Read more about these climatetech businesses, their founders, and their green initiatives below. Then join us at the Houston Innovation Awards on Nov. 13 at Greentown Labs, when the winner will be unveiled at our live awards ceremony.

Tickets are now on sale.

Anning Corporation

Clean energy company Anning Corporation is working to develop geologic hydrogen, a natural carbon-free fuel, using its proprietary stimulation approaches and advanced exploration modeling. The company said that geologic hydrogen has the potential to be the lowest-cost source of reliable baseload electricity in the U.S.

The company was founded by CEO Sophie Broun in 2024 and is a member of Greentown Labs. Last month, it also announced that it was chosen to participate in Breakthrough Energy’s prestigious Fellows Program. Anning raised a pre-seed round this year and is currently raising a $6 million seed round.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTech Nexus LiftOff, and others. Lee is an Activate 2025 fellow.

Eclipse Energy

Previously known as Gold H2, Eclipse Energy converts end-of-life oil fields into low-cost, sustainable hydrogen sources. It completed its first field trial this summer, which demonstrated subsurface bio-stimulated hydrogen production. According to the company, its technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

Eclipse is a spinoff of Houston biotech company Cemvita. It was founded in 2022 by Moji Karimi (CEO and chairman of Cemvita), Prabhdeep Sekhon (CEO of Eclipse), Tara Karimi, and Rayyan Islam. The company closed an $8 million series A this year and has plans to raise another round in 2026.

Loop Bioproducts

Agricultural chemical manufacturing company Loop Bioproducts leverages the physiology of prickly pear cactus grown in Texas to produce bioenergy, food, and remediate industrial wastewater streams. The company uses its remote sensing technology, proprietary image-based machine learning model, and R&D innovation to capture raw biogas from the cactuses and is focused on scaling cactuses as an industrial crop on land.

Rhiannon Parker founded Loop Bioproducts in 2023.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and converts them into pure chemicals and fuels that are free of carbon emissions onsite, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ catalyst program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as chief scientist, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round earlier this year.
