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.

Houston clean tech startup accelerator announces 7 companies to inaugural cohort

seeing green

The Low-Carbon Hydrogen Accelerator announced its inaugural class of clean tech startups — two of which hail from right here in Hosuton.

In all, seven startups have been chosen to participate this year in the Low-Carbon Hydrogen Accelerator, which was announced in November. The six-month accelerator program offers collaboration and engagement opportunities with the Electric Power Research Institute and its member utilities, as well as with Shell. Through the accelerator, the institute and Shell will provide startups with two innovation paths: a technology validation track and a technology demonstration track.

The accelerator — part of the Green Go program, affiliated with Greentown Labs — is aimed at coming up with innovations in low-carbon hydrogen production, storage, and distribution.

“Accelerating low-carbon hydrogen technologies is an essential part of achieving global net-zero targets by 2050,” Neva Espinoza, vice president of energy supply and low-carbon resources at the Electric Power Research Institute, says in a news release.

The inaugural LCHA cohort includes:

  • Advanced Ionics, based in Milwaukee, is enabling green hydrogen production without the green premium.
  • Arco Technologies from Bologna, Italy, is developing a proprietary Anion Exchange Membrane electrolyzer with the lowest capital expenditures and operating expenses possible today.
  • Based in Manchester in the United Kingdom, Clean Power is developing a novel, low-cost, highly durable hydrogen polymer electrolyte membrane fuel cell delivering zero-emission electricity.
  • Element Resources, based in Houston, is enabling compressed hydrogen storage tank technology.
  • Another local company, Smartpipe Technologies is developing a robust self-monitored repurposed pipeline system for hydrogen with minimal environmental disruption.
  • SPEC Sensors from California is creating a robust and reliable meshed sensor network for hydrogen leak detection and line-monitoring systems.
  • Canadian company RUNWITHIT Synthetics is creating a live, digital twin modeling platform that generates decision-support data for regional hydrogen-demand scenarios.

Element Resources, which produces hydrogen from renewables for mobility, power production, and energy storage, is collaborating with Zhifeng Ren, M.D. Anderson chair professor in physics and director of the Texas Center for Superconductivity at the University of Houston.

The other Houston startup, Smartpipe Technologies, announced earlier this month that Canadian pipeline company Enbridge had made a $6.6 million investment in the startup.

For 2022, the accelerator received applications from 88 startups in 18 countries. The five other participants this year are from California; Wisconsin; Alberta, Canada; Italy; and the United Kingdom.

Aside from the Electric Power Research Institute, Shell USA, and Greentown, the accelerator’s partners are the City of Houston and the Urban Future Lab at New York University’s Tandon School of Engineering.

“Creating a robust hydrogen economy will require a systems-oriented approach and unparalleled cooperation between corporate partners and emerging companies,” says Ryan Dings, chief operating officer and general counsel at Greentown Labs.

Greentown operates startup incubators in Somerville, Massachusetts, and Houston.

Overheard: Oil and gas experts weigh in on the future of low-carbon energy and Houston's role in the movement

Eavesdropping in Houston

As the energy capital of the world, Houston can't get complacent. The oil and gas industry is changing — carbon is out and finding clean energy alternatives is in.

At the 2020 KPMG Global Energy Conference on June 5 and 6, hundreds of energy professionals listened to the O&G elite — even including former Secretary of State and former ExxonMobil CEO Rex Tillerson — give their two cents about the revolution. Day two of the conference featured the Houston Low Carbon Energy Climate Summit by the Center for Houston's Future.

In case you missed it, here are a few powerful quotes from both days of the program — from Houston's role in the low-carbon energy movement to Tillerson's leadership expertise.

"Texas is one of those places where you can just get stuff done.”

— Cindy Yeilding, senior vice president at BP, says Texans are willing to collaborate on this. In the "Visions of our Energy Future" panel during the Low Carbon Energy Summit on Thursday, June 6, she predicted Houston will be a net zero carbon city by 2040 or 2035.

“One of the things we need to focus on is being able to attract and retain talent.”

— Mary Anne Brelinsky, CEO of EDF Trading, stressing the importance of talent in the effort to keep Houston the energy capital of the world. Brelinsky advocated for corporations and its execs getting involved with local universities. "We're competing against Silicon Valley," she says in the panel.

"You’ve got the source, and you’ve got the sinks. … Houston is going to be one of our focal points.”

— Charlene Olivia Russell, vice president of Low Carbon Strategies at Oxy, on how Houston is set up for success when it comes to staying as a power player in the global low carbon energy platform, but, during the panel, she emphasizes collaboration needs to continue happening.

“When Shell agreed to sponsor this summit, it was pitched as a climate change summit. It was changed to a low-carbon summit because some people in this room are uncomfortable with the phrase 'climate change.'"

— Jason Klein, vice president of U.S. Energy Transition Strategy at Shell, says at the "Energy Transformations" panel during the Low Carbon Energy Summit on Thursday, June 6.

"If we want to be the leader and the energy capital of the world, we need to attract talent, capital investment, and innovation, and if the people are going to do those things think that we don’t even like to talk about those things, then they aren’t going to come here — they’re going to go to San Francisco.”

— Klein continues. The audience responded with a round of applause.

“I think it is important as Americans to remember that our greatest strength and the most important element to our national security has been that we are a nation that has many allies and friends. Our adversaries — Russia, China, North Korea, Iran — have no allies or friends.”

— Former Secretary of State Rex Tillerson who served as CEO of ExxonMobil from 2006 to 2016. Tillerson discussed a wide range of topics on Wednesday, June 5, at the 2020 KPMG Global Energy Conference in his fireside chat with Regina Mayor, global sector head and U.S. national sector leader of energy and natural resources at KPMG US.

“We’re all a work in progress. You’re never done. I’m not done — I’m still a work in progress. If you have that view and you have that set of values that are never going to change … [then] I can keep developing as a human being.”

— Tillerson says of leadership lessons learned. He's an avid proponent of the Boy Scouts of America organization, and cited many valuable lessons he's learned about himself and about leading people from his involvement in the nonprofit.

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”

AI-powered Houston startup helps restaurants boost customer loyalty

order up

It’s no secret that restaurant trends move fast and margins run thin. And with the proliferation of platforms like Uber Eats, DoorDash and Easy Cater, customer loyalty is fleeting.

The solution?

How about an AI-powered restaurant technology platform that helps restaurant brands cut back on third-party platforms in favor of driving direct discovery, conversion and loyalty?

Enter Saivory. Founded in 2025 by Stephen Klein, a software investor, and Fajita Pete’s restaurateur Hugh Guill, the Houston-based startup aims to help eateries better understand and activate guest behavior across digital channels as AI increasingly reshapes how consumers discover and engage with brands.

In less than a year, Saivory has partnered with Shipley Do-Nuts and Fajita Pete’s to bring AI-powered ordering to life.

“With Saivory, we were able to answer the question of, ‘what if the ordering process could be reduced to a single step, where customers simply tell us what they want and AI takes care of the rest?’” Klein tells InnovationMap.

The Houston-based startup made such an immediate impact that it was selected as a semi-finalist during Start-Up Alley at MURTEC, the restaurant industry’s leading technology conference, which took place last month in Las Vegas.

“Houston is a great hub for technology innovation, and we were proud to represent the city at MURTEC this year,” says Klein. “We didn’t win, but we were able to talk about some of the work that we have existing in the market for clients right now and a little bit about what we’re working on in the future.”

In the current restaurant technology ecosystem, the third-party aggregators own the customer attention that brings volume to restaurants, while also taking big commissions and having control over the end relationships with the customer.

That can often make it difficult for restaurants to grow loyalty and repeat business from customers. Saivory aims to level the playing field for restaurants, helping them stay more connected to their customers.

Take Saivory’s recent application with Shipley’s Do-Nuts, for example.

Saivory powered the donut giant’s AI-ordering and launched Shipley's website and mobile app to support its over 300 locations in Texas alone.

Shipley’s new AI-powered assistant helps users create personalized order recommendations based on individual or group preferences. And unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size. It can also be used for large catering orders.

“They're seeing more traffic to the site and they're seeing when customers use our AI-enabled flows,” Klein says. “And they're seeing higher basket sizes, bigger tickets, by about 25 percent.”

Klein says Saivory’s technology helps strengthen first-party digital relationships, reduce friction and cart abandonment, improve average order value, and delivers personalized, efficient experiences.

“It’s a win-win: the customer gets the right order quickly, while the restaurant gets a bigger margin,” he adds.

Additionally, the technology makes it easier for restaurants to share rewards, loyalty and discounts, ultimately growing more direct traffic and making restaurants less reliant on third-party delivery apps.

Next up for Saivory is adding new components to its platform to enhance the relationship between restaurant and customer, as well as technology around making it easier for restaurants to get found on Google.

“A lot of people are still searching for the best donuts near me,” Klein says. “Or what’s the best Mexican food near me? Customers will increasingly move to AI, where they’re going to ask where they should eat dinner and expect it to just order them dinner. They will eventually expect the technology to know how to do that. So that’s what we’re driving at.”

Houston leads U.S. in population growth for 2025, Census says

Boomtown

Imagine that the Houston metro area swallowed a city the size of Pearland in just one year. That’s essentially what happened from 2024 to 2025, with the Houston metro ranking first in the U.S. for population growth based on the number of people.

New estimates from the U.S. Census Bureau show the 10-county Houston metro added 126,720 residents from July 1, 2024, to July 1, 2025. That’s just shy of Pearland’s roughly 133,000-resident tally.

To calculate population, the Census Bureau counts births, deaths, new residents, and moved-away residents.

Region’s population approaches 8 million

On July 1, 2025, the Houston metro’s population hovered slightly above 7.9 million, up 1.6 percent from the same time in 2024. In the very near future, the region’s population should break the eight million mark.

This follows massive growth in the past 20 years. From 2005 to 2025, the region’s population soared by 39 percent. By comparison, the growth rate from 2021 to 2025 sat at nine percent.

A forecast from the Texas Demographics Center indicates that under a middle-of-the-road scenario, the Houston metro’s population will reach nearly 8.5 million in mid-2030 and more than 9.5 million in mid-2040.

Dan Potter, director of Rice University’s Houston Population Research Center, attributes much of the region’s population surge to people moving to the area from outside the U.S. In Harris County, this means a combination of military personnel returning home, people living or working overseas coming back to the U.S., and immigrants relocating to the U.S., he tells CultureMap.

But Harris County fell short from 2024 to 2025 when it comes to people moving here from elsewhere in the U.S., according to Potter. Counties surrounding Harris County benefited from that trend, drawing new residents who preferred to settle in the suburbs.

“The incredible pull and attraction of the Houston area is its economy, its people, and its affordability, and the significant growth that was observed in 2024 and again in 2025 speaks to the magnetism of the region,” Potter says. “That pull to Houston is too strong to be turned off overnight.”

Cooling economy and immigration shifts slow down growth

Whether looking at urban or suburban places, population growth in the Houston area slowed in 2025 and appears to be slowing even more this year, Potter says.

“A cooling economy and changes to immigration policy are a one-two combination that could knock out the region’s population growth,” says Potter, citing the region’s addition of a less-than-expected 14,800 jobs in 2025 as an example.

Weaker population growth may not be felt evenly across the metro area, according to Potter.

A continuing influx of people from Houston to outlying counties such as Brazoria, Fort Bend, Liberty, Montgomery, and Waller could curb growth in Harris County, Potter said. Why? If the number of people arriving from other other countries flattens or even drops, then there could be “doughnut-style population growth for the next few years, where Harris County and Houston see declines while the suburban counties see an increase.”

Harris County represents 40 percent of region’s population lift

Houston-anchored Harris County accounted for almost 40 percent of the region’s population spike from 2024 to 2025. In one year, Harris County grew by 48,695 residents, or 1 percent, pushing its population past five million. That increase put Harris County in first place for numeric growth (rather than percentage growth) among all U.S. counties.

From 2020 to 2025, Harris County’s growth rate was 6.6 percent. It remains the country’s third largest county based on population, behind Southern California’s Los Angeles County and Illinois’ Chicago-anchored Cook County.

Harris County is on track to surpass Cook County in size in the near future. As of July 1, 2025, a nearly 150,000-resident gap separated population-losing Cook County and fast-growing Harris County.

The Texas Demographics Center predicts Harris County’s population will be 5.37 million in mid-2030 and just short of six million in mid-2040.

Suburban counties see significant population gains

Harris County isn’t the only county in the area that experienced a growth spurt from 2024 to 2025:

  • Waller County’s population climbed 5.69 percent, winding up at 69,858. Its growth rate ranked second among U.S. counties.
  • Liberty County’s population rose 4.4 percent to 121,364, putting its growth rate in eighth place among U.S. counties.
  • Montgomery County gained 30,011 residents, with its population landing at 781,194. That placed it at No. 4 among U.S. counties for numeric growth.
  • Fort Bend County picked up 24,163 residents, arriving at a total of 975,191 and positioning it at No. 8 among U.S. counties for numeric growth. Fort Bend County, the region’s second largest county based on population, is projected to break the one million-resident mark by July 2030, according to the Texas Demographics Center.

“Lower mortgage rates from 2009 to 2022 and the rise of remote work have made suburban housing more attractive, especially for families seeking affordability,” Pramod Sambidi, the Houston-Galveston Area Council’s assistant director of data analytics and research, said last year. “Additionally, suburban areas are seeing more multifamily developments than before the pandemic.”
