This week, Greentown Labs is hosting a two-day summit focused on elevating the conversation around clean energy and the energy transition in Houston and beyond, as well as serving as a showcase for emerging technologies coming out of Greentown's member companies.

"The main theme for this Climatetech Summit is commercialization, and we're trying to explore it in different ways," Juliana Garaizar, head of the Houston incubator and vice president of innovation for Greentown, says on this week's Houston Innovators Podcast. "We're going to have some great panels on rapid commercialization and Houston and the energy transition."

Last year, Houston played a role in Greentown's annual Climatetech Summit. The two-day streamed event in 2021 attracted over 2,500 viewers from 38 different countries. This year's event will return to in-person but keep the streaming element to maintain this opportunity to reach people all over the world. The summit kicks off on November 2 in Houston and continues on November 3 in Boston. (InnovationMap is a partner for the Houston portion of the summit.) Click here to read more.

Houston-area energy tech startup Syzygy Plasmonics just released a free online tool at CarbonModel.com that enables users to calculate the greenhouse gas emissions and emission-reduction costs in as little as 60 seconds. It’s a more straightforward way of making those calculations than is offered by Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model, the startup says.

Syzygy co-founder and CEO Trevor Best calls the Inflation Reduction Act “a major tailwind” for energy transition and hydrogen adoption.

“Existing hydrogen producers now have the fiscal support needed to sanction new projects. And companies that had been mulling hydrogen as a new business are incentivized to move more quickly,” Best says. “Both existing and new entrants in the hydrogen market want to know if their hydrogen is clean enough to qualify for [Inflation Reduction Act] tax credits.” Click here to read more.

UTHealth Houston team joins NASA initiative to protect border drinking water

water watch

Climate change means far more to public health than living with hotter days. Transformations in our weather are contributing to challenges in accessing safe drinking water in some communities.

One of the most dire situations is along the US–Mexico border. The National Aeronautics and Space Administration (NASA) is seeking to address that issue with its Water Quality Applications program. An 11-researcher project led by a UTHealth Houston School of Public Health faculty member has been selected to participate.

“Drinking water is one of the most fundamental public health protections, but producing safe drinking water involves a delicate balance,” Yun Hang, assistant professor of environmental and occupational health sciences, said in a news release. Her team’s proposal was one of 93 that were submitted for funding through NASA’s Research Opportunities in Space and Earth Sciences (ROSES)-2025 program.

This is the first time that NASA has worked with a team devoted to water quality applications. The group, which includes researchers from across the nation, will use satellite observations of Earth, as well as hydrologic modeling, to potentially anticipate and act on water quality conditions as they change. Challenges addressed over the course of the three-year program, which kicked off in June, might include problems with water quality due to climate variability and increased pressure on water resources.

Hang’s team will focus on a pair of borderlands: Paso del Norte and the Rio Grande Valley.

“Working closely with El Paso Water ensures that our research addresses real operational needs while helping utilities better prepare for climate-related water quality changes and continue providing safe drinking water to communities across the Texas border region,” Hang added in the release.

She and the team will use data gathered by NASA on both past and future Earth-observing missions, which will allow them to track environmental changes that may affect source water quality. Combined with past water treatment records and hydrologic models, the team will also utilize artificial intelligence to develop predictive tools that aim to stop issues before they become larger hurdles to water safety.

Another one of the project’s goals is to create visualization tools and source water summaries that can be utilized by those without scientific expertise. The tools will be produced in English and Spanish to further broaden their accessibility.

The hope is that the materials made by the team will also go far beyond the border, with protocols that can be adapted or adopted by other areas dealing with water quality issues.

Houston helps power Texas’ rise as AI infrastructure hub, new report finds

eyes on ai

Houston plays a major role in Texas’ rapidly evolving AI economy, a new report indicates.

The report from Build American AI, a pro-AI advocacy group, notes Houston’s growing AI presence includes:

  • A factory being built by AI chipmaker NVIDIA and electronics manufacturer Foxconn that will produce AI supercomputers and infrastructure systems
  • Houston Methodist’s use of ambient AI to listen to health care providers’ conversations with patients, eliminating the need for manual notetaking
  • An abundance of AI products and services for the energy sector

Across the state, billions of dollars in new AI investments are fueling advancements in construction, manufacturing, energy production, logistics, and health care, according to the report.

“Texas is not merely a place where AI products will be used. Texas is becoming one of the places where the AI economy is being assembled,” the report says.

Particularly noteworthy are four major AI-related projects around the state representing an investment of more than $140 billion, including Google’s $40 billion buildout of AI data centers.

“While California had a headstart in building the software era, Texas will build the infrastructure era,” says the report. “That is not a slogan. Economic research has revealed for decades that innovation happens where the local conditions make building and collaboration possible, and Texas is positioned to be a central hub.”

According to the report, components of Texas’ infrastructure era include:

  • Energy leadership
  • Top-tier hospitals
  • Semiconductor investments
  • Construction capabilities
  • Data center growth
  • Major companies and universities

On the workforce front, Stanford University’s 2026 AI Index found Texas had 80,547 AI job postings in 2025, accounting for 8 percent of the national total.

“Texas no longer needs to ask whether AI will reshape the economy. It already has,” the report concludes. “The question is whether Texas will merely host part of that future or lead it.”
