It's all hands on deck for pioneering technology to advance the energy transition and climatetech, and three companies with a Houston presence just took the national stage to showcase their climate change solutions.

The United Nations' 2021 COP26, hosted by the Net Zero Technology Centre in Glasgow, featured 10 startup organizations from across the globe battling it out to be crowned the Clean Energy Startup Champion.

The Ion Houston nominated five startups to the competition, and three made it to the finals. Syzygy Plasmonics, which is developing a new type of photocatalytic chemical reactor to reduce both cost and emissions for major commodity chemicals, claimed third place in the competition. The other two Ion nominees that pitched were:

  • S2G Energy, an Ion Smart Cities Accelerator participant, and cloud-based Energy Assistant platform that collects data and manages devices from almost any source to capture efficiency opportunities
  • Cemvita Factory, which applies synthetic biology to reverse climate change and transform CO2 into a usable material
"The Ion partnered with Net Zero with the vision to bring innovative and transformative startups out of the North/Central and South American market to the stage in Glasgow," says Jan E. Odegard, executive director of The Ion, in a statement. "We took a look around our own ecosystem both at The Ion and the Ion District and S2G Energy, Syzygy Plasmonics, and Cemvita Factory were easy and obvious nominations, as they were all working towards achieving net zero and are exemplars of startup innovation within our ecosystem."
Australia-based Mineral Carbonation Int'l, focused on carbon transformation, claimed first place and the title of top Clean Energy Startup Champion. PJP Eye, based in Japan and working on commercialised plant-based carbon batteries, came in second.

In light of COVID-19, it is more relevant than ever to discuss and support startups with sustainability and resiliency in mind. At The Ion Smart and Resilient Cities Cohort 2 Demo Day, a virtual audience was reminded of that.

"So, 2020 has certainly been a year of unprecedented uncertainty and change for Houston, for Texas, for our country, and for our world," says Christine Galib, director of the accelerator. "The past few months in particular have been especially difficult as the global pandemic and civil unrest continue to spotlight systemic and structural scars on the face of humanity."

The virtual event was streamed on July 1 and hosted several thought leaders and presenters before concluding with pitches from four of the cohort companies.

"Through it all, and in a virtual world, Cohort 2 startups, the mentors, and our Ion team have been the change we wish to see in the world," Galib continues. "For these startups, failure is simply not an option — and neither is going at it alone."

Earlier this year, Galib announced the second cohort would be focused on solutions for Houston's air quality, water purification, and other cleantech needs. The program, backed by Intel, Microsoft, and TX/RX, launched on Earth Day and commenced shortly after. Cohort 3 is expected later this year.

Here are the four companies that pitched and the problems they are trying to solve.

Re:3D

re:3D was founded just down the street from NASA's Johnson Space Center to address the need for a mid-market 3D printing solution. The Houston-based startup also wanted to create their 3D printer that operates on recycled plastics in order to prevent excess waste.

"Where some see trash, we see opportunity," Charlotte Craff, community liaison at Re:3D says in her presentation.

Re:3D's clients can get their hands on their own Gigabot for less than $10,000, and the printer uses pellets and flakes from recycled plastics —not filament — to print new designs. Clients are also supported by the company with design software and training.

"We can help the city of Houston help meet its climate action and resilient city goals by transforming the way people think about recycling," Craff says about Re:3D's future partnerships with the city.

Water Lens

While two-thirds of the world is covered in water, only 0.7 percent is drinkable. And of that fresh water, 92 percent of it is used in agricultural and industrial settings. This is how Keith Cole, CEO and founder of Water Lens, set the scene for his presentation.

Water Lens, which is based in Houston with a lab located in Austin, wants to solve the problem of cities and countries running out of fresh, drinkable water by equipping huge water-using companies with a water testing tool.

"We've developed a system to let anyone test any water literally anywhere in the world," Cole says, citing clients like ExxonMobil, Shell, and Halliburton.

S2G Energy

S2G Energy, based in Mexico, is focused on optimizing energy management in order to digitize, empower, and unlock potential for cost-saving efforts and technology.

In his pitch, Geronimo Martinez, founder of S2G Energy, points out that restaurants, commercial buildings, and other adjacent industries can save money by implementing energy management solutions that come out of S2G Energy's expertise. In Mexico, Martinez says, clients include the top two restaurant chains that — especially during COVID-19 — need optimization and cost saving now more than ever.

Eigen Control

A refinery's distillation columns are expensive — their fuel use accounts for 50 of operating costs, says Dean Guma, co-founder and CEO of Houston-based Eigen Control.

Guma explains in his pitch how Eigen Control's technology can plug into existing sensors, model networks based on data, and employ the startup's artificial intelligent technology to reduce carbon emissions and save money on operating costs.

Houston accelerator announces newest cohort to tackle cleantech

Smart cities

As the world celebrated the 50th annual Earth Day on April 22, a Houston innovation organization announced a new group of startups for its accelerator program that will focus on cleantech solutions within the city of Houston and beyond.

The Ion's accelerator, which recently renewed its focus on resiliency, announced its second cohort with six startups that will create solutions for Houston's air quality, water purification, and other cleantech needs.

"Through leveraging the power of our local Ion community, The Ion Smart and Resilient Cities Accelerator is committed to solving challenges Houstonians face every day," says Christine Galib, senior director of accelerator programs at The Ion and the director of the accelerator, in a news release. "We connect participating startups with mentors, partners, and stakeholders, so they gain access to the resources they need to build, validate, and scale their technologies. Together, we are building a safer, smarter, and more accessible city for all Houstonians."

The program is supported by Intel, Microsoft, and TX/RX and has began its programming for the new cohort. The six startups selected for the program are:

  • Houston-based Eigen Control uses machine learning and chemical engineering models to combat rising CO2 emissions. Distillation process plants emit so much CO2 — and Eigen Control's processes are working to change that.
  • Houston-based Annapurna Solutions has cloud-based solutions for hazardous and solid waste management.
  • Mexico City-based S2G Energy focuses on sustainable and optimized solutions for businesses and governments with its energy-management-as-a-service technology.
  • Houston-based re:3D is a 3D-printing nonprofit that is democratizing small-scale manufacturing. Its Gigabot can use recycled and reclaimed materials for more sustainable and affordable production. The company, which has offices in Puerto Rico and Austin, donates a printer to someone making a difference with every 100 printers it sells.
  • Austin-based LifePod Corps is a nonprofit that provides disaster relief through renewable and sustainable technologies built and delivered by military veterans.
  • Houston-based Water Lens has created a real-time water data analytics platform for industries that use a lot of water — like oil and gas, agriculture, power generation, coal mining, and food processing. The technology allows for quicker, more reliable results.

The accelerator's leaders chose its theme for the cohort based on the City of Houston's Resilient Houston Strategy and Climate Action Plan. The program has identified these six startups as movers and shakers within these Smart Cities challenges.

"We are thrilled to collaborate with these startups to further develop Houston as one of America's smartest and most resilient cities," says Gabriella Rowe, executive director of The Ion, in the release. "By leveraging our resources and networks, the accelerator and Cohort 2 improve living conditions for all Houstonians. In this way, we stimulate our local economy with new jobs and economic opportunities."

Last year's inaugural cohort was announced in August and focused on resilience and mobility. After a demo day in December, the cohort continued its work in Houston through 15 pilot programs the startups had with the city. The third cohort is expected to launch toward the end of 2020, but the next theme has not yet been decided.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
