As a startup hub, Houston is movin’ on up.

In a new report from Startup Genome and the Global Entrepreneurship Network, Houston ranks fifth among the world’s top 100 emerging ecosystems for startups. Last year, the groups’ report put Houston at No. 19 in the same category.

Ahead of Houston on the list of the top emerging ecosystems for startups are first-ranked Detroit; second-ranked Hong Kong; third-ranked Dublin, Ireland; and fourth-ranked Minneapolis.

Further bolstering Houston’s status as a rising startup hub, Bayou City ranks third among the top North American challengers to traditional startup anchors like Silicon Valley, Boston, and Seattle. Joining Houston on the challengers’ list are first-ranked Detroit; second-ranked Minneapolis; third-ranked Research Triangle, North Carolina; and fifth-ranked Pittsburgh.

A recent report from Houston Exponential, which was recently acquired, emphasizes Houston’s position as the third fastest-growing tech ecosystem in the U.S. for early-stage startups. Houston sits behind Miami (No. 2) and Bridgeport-Stamford-Norwalk, Connecticut (No. 1).

Houston startups at all stages raised $2.34 billion in 2021, setting a record for the region’s annual VC haul, the HX report says. Of that total, early-stage startups collected $618.9 million in 46 deals.

Health and information technology startups dominate the VC landscape in Houston, with each accounting for 30 percent of VC deals in 2021, according to the HX report.

Elsewhere in Texas, Austin ranks 25th among the world’s top 100 ecosystems for startups, while Dallas ties for 31st place, according to the Startup Genome and Global Entrepreneurship Network report. San Antonio is wedged into the 91-to-100 range in the ranking of the world’s top 100 ecosystems.

“The importance and dispersal of tech startups have amplified the influence — for both good and ill — of geopolitics,” the report notes. “Where once the sector was sufficiently small to avoid the kind of pressures experienced by large industries such as energy and travel, those garage-spawned entrepreneurs have grown into a major economic force. Keeping their heads down is no longer an option.”

Self-driving pizza delivery vehicles will hit Houston's roads later this year

Order up

Unmanned vehicles are taking over Houston, any way you slice it. Nuro, the robotics company specializing in commercialized self-driving cars, first entered the Houston market earlier this year with its grocery delivery partnership with Kroger. Now, the company has teamed up with Domino's Pizza to deliver an autonomous pizza delivery pilot program in Houston.

Only a select group of Houston Domino's customers will be able to have the option to choose an unmanned delivery process from the R2 vehicles. Currently, Nuro and Domino's have not revealed who will be able to use the service or when. In a news release from Domino's, the company notes that the technology will be available later this year.

"We are always looking for new ways to innovate and evolve the delivery experience for our customers," says Kevin Vasconi, Domino's executive vice president and chief information officer, in the release. "Nuro's vehicles are specially designed to optimize the food delivery experience, which makes them a valuable partner in our autonomous vehicle journey. The opportunity to bring our customers the choice of an unmanned delivery experience, and our operators an additional delivery solution during a busy store rush, is an important part of our autonomous vehicle testing."

On online orders, select customers will have the option to choose to receive delivery from one of the R2 vehicles. Once the order is in, the customers would receive a PIN code to unlock the compartment to access the pizza upon its arrival.

"We are excited to expand our autonomous delivery service in Houston with Domino's delivery," says Cosimo Leipold, Nuro's head of partner relations, in the release. "Domino's delivers millions of pizzas around the world every day, and the company shares our passion for focusing on the customer experience. We see incredible opportunity in offering Nuro's world-class autonomous technology to Domino's customers, accelerating our shared mission to transform local commerce."

Self-driving vehicles are sure to change Houston's landscape, according to Rand Stephens, managing director of the Houston office of commercial real estate services company Avison Young.

"I think forward-thinking tenants, developers, brokers, architects, and engineers will design interim solutions with lower ratios," Stephens says in another InnovationMap article. "They'll really take the time to understand the occupants' commuting patterns and steer away from one parking space for one person."

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

As anticipated, Spring-based oil and gas giant ExxonMobil has officially paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters in late November.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
