Three Houston energy innovators have cut the ribbon on a new space for energy transition innovation.

The Energy Tech Nexus, located in the historic Niels Esperson Building at the corner of Travis and Rusk Avenue, opened on September 10, which was proclaimed Energy Tech Nexus Day by the city.

Jason Ethier and Juliana Garaizar, formerly in leadership roles at Greentown Labs, teamed up with Nada Ahmed, previously headed innovation and transformation at Aker Solutions, launched ETN as a community for energy transition startups. The new hub plans to host incubation programs, provide mentorship, and open doors to funding and strategic partnerships for its members.

"We are creating more than a space for innovation," Garaizar, who serves as CEO of ETN, says in a news release. "We are crafting a community where pioneers in technology and energy converge to challenge the status quo and accelerate the shift to sustainable energy solutions."

The hub describes its goal of tackling the "trilemma" of energy security, sustainability, and affordability while also contributing to the mission of setting up Houston as the global center for energy transition. To accomplish that mission, ETN will help facilitate rapid deployment of cutting-edge energy technologies.

'The future of energy is not just being written here in Houston; it's being rewritten in more sustainable, efficient, and innovative ways," adds Garaizar. "Houston provides the perfect backdrop for this transformation, offering a rich history in energy and a forward-looking approach to its challenges and opportunities."

"We believe that a broad spectrum of perspectives is crucial in solving global energy challenges. It's about bringing everyone to the table — startups, industry leaders, and investors from all backgrounds," she continues.

Ethier, who co-hosts the Energy Tech Startups Podcast with Ahmed, says he hopes that ETN acts as a meeting place for energy transition innovators.

"By providing the right tools, access, and expertise, we are enabling these companies to leap from ideation to implementation at an unprecedented pace;" Ethier explains. "The interaction between startups and established companies within Energy Tech Nexus creates a unique synergy, fostering innovations that might otherwise take years to mature in isolation."

Payal Patel, an angel investor who has held leadership roles at Station Houston, Plug and Play Ventures, and Softeq, also contributed to launching ETN, which is collaborating with George Liu, who has over 15 years of investment banking experience across energy, cleantech and hardtech with more than $20 billion in M&A projects across his career.

In May, ETN teamed up with Impact Hub Houston to establish the Equitable Energy Transition Alliance and Lab to accelerate startup pilots for underserved communities. The initiative announced that it's won the 2024 U.S. Small Business Administration Growth Accelerator Fund Competition, or GAFC, Stage One award.

ETN celebrated its opening during the inaugural Houston Energy and Climate Week.

Houston's innovation leaders weigh in on community's growth, progress

Houston innovation awards

This year's finalists in the Ecosystem Builder category for the Houston Innovation Awards have a lot to say about the city's innovation community — and they are the right ones to say it.

Selected as finalists for the newly created category, each of the five finalists are leaders for the Houston innovation ecosystem. They were each asked some questions about the development of the Houston tech and startup community. Here's what they had to say.

InnovationMap: What is your favorite part of Houston's innovation ecosystem? How have you helped contribute to that aspect of the community?

Jan E. Odegard, executive director of the Ion: Can do attitude and willingness to make big bets that can solve hard problems with global societal impact. Creating and supporting a place where this can happen is critical to the success, a place where we create the necessary density for collisions and that will sprue the next ideas.

Jason Ethier, co-founder of Lambda Catalyzer and host of the Energy Tech Startups podcast: Perhaps small, but the Ion District in the small part we have to play in it. Being able to be in a place where you can cross paths with active investors, innovators and partners. This is the hub we hoped to build over the last few years. That connective tissue may be small and focused compared to other ecosystems, but it is very strong here.

Joey Sanchez, founder of Cup of Joey and senior director of ecosystems at the Ion: My favorite part of the Houston Innovation Ecosystem is the progress and potential. We have gone from talking about how to build a Houston ecosystem to now exploring our collective potential. The conversations are now tactical actions to scale our efforts.

Kendrick Alridge, senior manager of community at Greentown Labs: My favorite part of the ecosystem is the Cup of Joey gathering. It's a great opportunity to run into or catch up with people looking to get involved in the ecosystem or looking for support. It's a great networking opportunity.

Wade Pinder, founder of Product Houston: I love seeing how the community has really connected this past year specifically. We've gathered momentum and have a "gravity well" of community leaders feeding value to one another.

IM: What are the strengths of the Houston innovation ecosystem?

Odegard: Access to (engineering) talent, capabilities, and global connectivity that are not afraid of getting her hands dirty to build and scale.

Ethier: The diversity of the founders and the intrinsic diversity of the Houston ecosystem. There are few native Houstonians, and most of the fantastic founders we meet are from somewhere else. The energy industry brings the best of the best from around the world and they inject Houston with unique excellence.

Sanchez: We are a resource right environment. We have a plethora of talent and capital. With the economy the size of Belgium, we have access to industries and talent unlike any other city. Also the convergence of energy, medical and aerospace is one of a kind. Each industry is transforming and providing a ripe opportunity for innovation.

Alridge: The growing number of startup development organizations (SDOs), incubators and accelerators, makerspaces, co-working spaces, non-profits, and academic institutions that is available is a strength, because their are plenty of places to get support and your ideas off the ground.

Pinder: We do hard things here because the ARE hard! 1) Life and death situations en masse, 2) infrastructure at scale 3) Boldly going where no one has gone before! That's what we've done here. That's what we stand to innovate on! If it's a hard problem, Houston gets it done!

IM: What are the weaknesses of the Houston innovation ecosystem? Are you helping to make improvements to these weaker aspects of the community and, if so, how?

Odegard: Access to more risk capital.

Ethier: We need a skill set on scaling businesses. This is something the valley does exceptionally well. When there is product market fit, the startup ecosystem knows how to scale teams from 20-200 and do so repeatedly. Houston knows how to do big energy projects; from sput to TD, there is a skill set here around complexity...but how that applies to scaling businesses its unclear we have what it takes. This is why its imperative we bring in mature startups from around the country and try to transfer knowledge from the energy industry into the startup space. Building an acceleration program like Lambda is a step in solving this problem.

Sanchez: Density is our biggest challenge. The geographic sprawl of our region is vast. Serendipitous meetings are a challenging. The Ion has created a central place where our ecosystem can come together. Every Friday we meet for Cup of Joey and now we host a Cup of Joey in The Woodlands, Space Center Houston, Sugar Land and The Cannon West. Creating eight Cup of Joey meetups each month. The most exciting element of Cup of Joey is coming in an online platform for connection.

Alridge: We need a robust cadre of startup specialists, serial entrepreneurs who have successfully started companies. Especially in business and STEM fields, is needed in the innovation system. Higher education in providing talent is important, I'm doing my part by organizing opportunities for students to work with our startups which can directly and indirectly contribute to the workforce and the grown startup community.

Pinder: We're changing this... but we still have a ways to go with the "I'm good... what do I need to show up for?" thinking. It's not for lack of wanting to show up... traffic makes it tougher to show up most of the time.

IM: What do you wish more people knew about the Houston startup community?

Odegard: That Houston IS a tech hub addressing some of the biggest societal challenges we are face today, such as: power (security), healthcare (affordable and accessible), sustainability (clean and green), and equitable access to economic opportunities.

Ethier: How climate focused everyone is, from the founders, to the SMEs, industry and SMEs. Houston (and energy companies) know how to manage what's measured and now that we have targets around decarbonization, we are going to get it done.

Sanchez: I wish the world knew more about Houston and our Houston startup community. I believe that our foundation is strong and we are ready for scale. 2026 to 2036 will be a decade of massive growth for Houston and our ecosystem.

Alridge: We are more than oil and gas and health care.

Pinder: We've got the solutions to some huge problems sitting right here in Houston.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from clean energy to materials science — recently making headlines in Houston innovation.

Jason Ethier, senior director of membership at Greentown Labs

Jason Ethier witnessed Greentown Labs, a climatetech incubator based in Somerville, Massachusetts, outside of Boston, from its early days.

"Greentown is one of those things where a business seems obvious in retrospect," says Ethier, a serial energy entrepreneur, on this week's episode of the Houston Innovators Podcast, explaining how the incubator launched as just a way to enable coworking between startups. As it grew and eventually expanded to Houston, Ethier had a front-row seat.

Ethier, whose previous startup brought him to Houston frequently, recognized the same scrappy founder mentality and need for incubation support in the Bayou City and was a key player in expanding Greentown to Houston in 2021.

"Every city is proud of who they are, but I think Houston especially is a city that likes to solve problems and build things locally," Ethier says. "When presented the opportunity to help build and ecosystem here, members of the ecosystem raised their hands and said, 'how can I help.'" Read more.

For a year, Megan Eddings, founder of Accel Lifestyle, has been working on the logistics of getting her clothing — made from eco-friendly, sustainable, antibacterial fabrics — into Talbots, and she's finally sealed the deal.

Shoppers can now find Accel Lifestyle apparel on Talbot's website. This partnership marks the first-ever collaboration for the athleisure brand of Talbots, T by Talbots. By teaming up with Accel Lifestyle, Talbots expands its product offerings and also provides its loyal, forward-thinking, and ethically minded customers with a new clothing option that perfectly fits with their values.

"We are beyond elated about the Accel x Talbots launch," Eddings tells CultureMap." Amanda Cotler, Accel's Director of Operations, and I have been working on this opportunity for a year, and it feels incredible for the collaboration to be live. Our passions are textiles with technology and an ethical made-in-the-USA supply chain. To have a multi-billion dollar company like Talbots care about the same things brings us so much joy."

Houston-founded Cart.com, which provides a suite of software solutions for commerce and logistics enablement, can now check the box saying "unicorn" with its $1.2 billion valuation that came with its $60 million series C equity funding round.

According to a news announcement from the company, Cart.com will use the funding for international expansion, continued product development, and to meet increased client demand.

“We are proud to partner with this prestigious group of investors to accelerate our growth and continue to deliver best-in-class solutions to our customers,” says Omair Tariq, CEO and co-founder of Cart.com, in a statement. “As a leading commerce software and services provider, we are focused on enabling our customers to compete and win across every channel through digital tools and digitally driven logistics capabilities. We will continue to invest in our industry-leading commerce data capabilities, which are built to address the specific inventory, channel and supply chain challenges facing enterprises.” Read more.

Why this innovator is dedicated to supporting, showcasing Houston energy tech startups

HOUSTON INNOVATORS PODCAST EPISODE 192

Like many successful operations, Greentown Labs, a climatetech incubator based in Somerville, Massachusetts, outside of Boston, had its humble beginnings.

"Greentown is one of those things where a business seems obvious in retrospect," says Jason Ethier, a serial energy entrepreneur, on this week's episode of the Houston Innovators Podcast.

He says he and a few other founders were working on their various ventures in a building that ended up getting slated for demolition, forcing them to find a new place to set up shop.

"We were all building stuff within energy and technology," Ethier remembers. "We had to find a new building, and the landlord looked at us and said, 'I don't want to deal with a bunch of small companies. I want one company, one check, and one lease."

The group of entrepreneurs formed Greentown as a way to make the rent work, but they started attracting interest from other founders who wanted in. The organization evolved to what it is today — a dual-located energy incubator that's supported over 500 companies that have raised over $4 billion in funding.

Ethier, whose startup at the time brought him to Houston frequently, recognized the same scrappy founder mentality and need for incubation support in the Bayou City and was a key player in expanding Greentown to Houston in 2021.

Juliana Garaizar, who was hired as launch director for Houston and now is head of Greentown Houston, tapped Ethier to support the expansion into town. Now, as senior director of membership at Greentown Labs, he works hands on with startups at Greentown.

He's taken his knowledge as a serial entrepreneur and incubation leader to launch the EnergyTech Startups podcast with co-host Lara Cottingham, the vice president of strategy, policy, and climate impact at Greentown Labs.

"As an entrepreneur, sometimes you feel a gap in the market in your bones and you just have to do something about it," Ethier says, explaining that he observed that when meeting people, he realized Houston got a bad rap. "Houston isn't viewed as a cool place to build a company if you don't know how good it is to be here."

The other thing Ethier says he realized was that Houston founders were understated in what they accomplished. So, he set out to start a podcast that would shine the spotlight on a Houston energy entrepreneur on a regular basis. The show, launched last fall, das now introduced listeners to over 20 energy founders and is continuing to do so on a biweekly basis.

Ethier shares more on his views of the future of Houston as an energy transition leader on the show. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston team develops low-cost device to treat infants with life-threatening birth defect

infant innovation

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Generally, a single-use bag can cost between $200 and $300. The alternatives that exist lack structure and require surgical sewing. This is where the SimpleSilo comes in.

“We focused on keeping the design as simple and functional as possible, while still being affordable,” Vanshika Jhonsa said in a news release. “Our hope is that health care providers around the world can adapt the SimpleSilo to their local supplies and specific needs.”

The study was published in the Journal of Pediatric Surgery, and Jhonsa, its first author, also won the 2023 American Pediatric Surgical Association Innovation Award for the project. She is a recent Rice alumna and is currently a medical student at UTHealth Houston.

Bindi Naik-Mathuria, a pediatric surgeon at UTMB Health, served as the corresponding author of the study. Rice undergraduates Shreya Jindal and Shriya Shah, along with Mary Seifu Tirfie, a current Rice360 Global Health Fellow, also worked on the project.

In laboratory tests, the device demonstrated a fluid leakage rate of just 0.02 milliliters per hour, which is comparable to commercial silo bags, and it withstood repeated disinfection while maintaining its structure. In a simulated in vitro test using cow intestines and a mock abdominal wall, SimpleSilo achieved a 50 percent reduction of the intestines into the simulated cavity over three days, also matching the performance of commercial silo bags. The team plans to conduct a formal clinical trial in East Africa.

“Gastroschisis has one of the biggest survival gaps from high-resource settings to low-resource settings, but it doesn’t have to be this way,” Meaghan Bond, lecturer and senior design engineer at Rice360, added in the news release. “We believe the SimpleSilo can help close the survival gap by making treatment accessible and affordable, even in resource-limited settings.”

Oxy's $1.3B Texas carbon capture facility on track to launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
