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.

The Ion taps John Reale for startup and investor role

new hire

The Ion has named John "JR" Reale as its director for startups and investor engagement.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."

Houston's IAH soars in new ranking of U.S. airports with best dining

Flying High

Here's news that'll make a flight delay at Houston's George Bush Intercontinental Airport a bit more palatable: IAH arrives at No. 12 in a new ranking of the country’s best airports for food and beverage options.

The 2025 study by commercial furniture manufacturer Restaurant Furniture relied on Google reviews of food and beverage establishments at the busiest U.S. airports to come up with its list. The study included only those restaurants and bars with at least 20 Google reviews.

IAH earned an average Google review rating of 3.29 out of 5 stars for its food-and-beverage establishments.

The study analyzed 61 restaurants and bars at George Bush Intercontinental Airport. The Houston airport’s highest rated establishment was Pappadeaux Seafood Kitchen. That Pappadeux location garnered an average Google review rating of 4.48 out of 5. George Bush International also is home to the study’s highest-rated Chick-fil-A and Whataburger restaurants.

Several years ago, IAH made a major effort to upgrade its dining options by partnering with local chefs such as Chris Shepherd, Ryan Pera (Coltivare), and Greg Gatlin (Gatlin's BBQ) on concepts for Terminal C North. More recently, a change in the city's airport concessions contract brought local favorites such as The Annie Cafe and Common Bond to the George Bush.

“Airports aren’t usually renowned for their choices of bars and restaurants, and this is often because people just want to get through the airport and onto their final destinations as quickly as possible,” Nick Warren, head of e-commerce at Restaurant Furniture, says in a release. “However, a good airport bar or restaurant can provide a great rest stop after a long flight, and these positive experiences can go a long way towards travelers choosing which airport they will fly from in the future.”

Dallas Fort Worth International Airport soared to No. 1 in the rankings. Restaurants and bars at DFW earned an average of 3.56 out of 5 stars on Google — the highest number among 31 airports.

Just like in Houston, among 74 locations at DFW, the study found Pappadeaux Seafood Kitchen in Terminal A scored the highest average Google review rating — 4.59. DFW also boasts the top-rated IHOP, McDonald’s, Panera Bread, and Panda Express among the 31 airports that were analyzed.

Rounding out the top five airports with best food are Miami International Airport (No. 2), San Francisco International Airport (No. 3), Denver International Airport (No. 4), and Hartsfield-Jackson Atlanta International Airport (No. 5).

Axiom Space launches semiconductor and astronaut training initiatives

space projects

Axiom Space, a Houston-based commercial spaceflight and space infrastructure company, has launched initiatives in two very different spheres — semiconductors and astronaut training.

On the semiconductor front, Axiom has signed a memorandum of understanding with Japanese chemical company Resonac Corp. to collaborate on semiconductor R&D and manufacturing projects carried out in space. Among Resonac’s products are materials used in chip manufacturing.

Axiom said the deal “paves the way toward leveraging microgravity to advance next-generation chip technologies and accelerate the in-space manufacturing market.”

Under the agreement, Axiom and Resonac will explore the potential production of semiconductor materials and chip packaging in microgravity and low-Earth-orbit environments.

“The unique environment of space offers immense potential for advancing semiconductor materials, especially in crystal growth,” Masato Fukushima, Resonac’s chief technology officer, said in a news release.

The deal will also extend Resonac’s work with Axiom on the development of molding compounds that can reduce “soft errors” when semiconductor devices are exposed to space radiation.

“Our collaboration with Resonac underscores how Axiom Space is enabling global corporations from around the world to leverage space to drive manufacturing innovation across critical technology sectors such as semiconductors,” Axiom astronaut Koichi Wakata, the company’s chief technology officer, said.

In the astronaut training arena, Axiom has tapped Portuguese physiologist Emiliano Ventura as its first “Project Astronaut.” Ventura will apply his expertise in human performance to a pilot program aimed at testing six-month astronaut training protocols.

“His goal is to participate in a future mission and explore, with scientific depth and curiosity, how the human body adapts to microgravity, contributing fresh insights to the current body of research in space physiology,” Axiom said.

Ventura has helped several Axiom crewmembers with physiological needs before and after missions aboard the International Space Station.

Axiom said Ventura’s pilot program will study astronauts’ physiological responses to microgravity during spaceflight. The program eventually will benefit Axiom astronauts heading to the world’s first commercial space station, which is being built by Axiom.

Michael López-Alegria, Axiom’s chief astronaut, said he and the company’s two other astronauts will train with Ventura. The Project Astronaut initiative “strengthens our commitment to enabling safe, effective, and inspiring commercial space missions while supporting scientific objectives worldwide.” López-Alegria said.
