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.

Houston ranks No. 2 for share of AI talent in professional services

AI surge

Houston’s professional and business services sector—think law, accounting, consulting, and engineering firms—grabs one of the industry’s biggest shares of AI talent.

A report from commercial real estate services giant CBRE ranks Houston No. 2 among the top 50 U.S. and Canadian tech markets for the concentration of AI talent in professional and business services.

Houston’s share of AI talent in professional and business services stands at 26 percent, the report shows. Washington, D.C., tops the list at 31 percent. At 25 percent, Dallas-Fort Worth claims the No. 3 spot.

CBRE based the AI ranking on data from the LinkedIn networking platform.

The company’s researchers tallied 11,709 AI-related tech jobs in Houston. Nationwide, data scientists lead AI-related job growth in the U.S., according to the report.

“AI software and hardware developers are currently the most sought-after tech talent by employers,” the report says.

Houston faces AI talent gap

DoubleTrack, a provider of AI and data consulting, reported in June that Houston faces an AI talent gap.

“The places where businesses say they will adopt AI over the next six months, well ahead of where they are today, are mostly the same places already short on talent: Miami, Houston, and Denver among the metros, South Dakota and South Carolina among the states,” DoubleTrack said.

This labor shortage comes amid Houston’s ascent as an AI hub. For instance, a factory being built here by AI chipmaker NVIDIA and electronics manufacturer Foxconn will produce AI supercomputers and infrastructure systems.

Houston’s place in the sphere of tech talent

Overall, Houston ranks No. 32 in the CBRE report among the top 50 U.S. and Canadian markets for tech talent. The San Francisco Bay Area claims the top spot, with Austin at No. 5 and DFW at No. 8.

CBRE relied on 13 metrics to rank tech talent markets, including concentration of tech talent, tech talent pipeline, and research-and-development investments.

Here are other Houston details from the report:

  • In 2025, Houston’s tech talent workforce numbered 104,080, up 7.3 percent over the past three years.
  • Houston’s average wage for tech talent within the tech industry was $120,216 in 2025, up 13.3 percent over the past three years.

New pilot program for air taxis, Project Nexus, takes flight in Texas

Project Nexus

By 2029, Texas skies could be buzzing with air taxis, much like they are with drones today.

To kick off the "Project Nexus" pilot program in Texas, U.S. Transportation Secretary Sean Duffy, U.S. Sen. Ted Cruz, and Texas Department of Transportation officials attended an event September 10 at Fort Worth Alliance Airport, which serves as the launchpad for a statewide pilot program that could result in air taxis, self-piloted planes, and vertical take-off-and-landing aircraft permanently buzzing across the skies of Texas.

It was the first demonstration in Texas of next-generation aircraft under the pilot program; Texas is the sixth state to participate in the program.

Air taxi service on the radar
The federal government has teamed up with aviation companies BETA Technologies and Joby Aviation, as well as the Texas Department of Transportation, to develop regional air taxi service in Dallas, Austin, San Antonio, and eventually Houston.

Roger Venables, Fort Worth’s aviation director, said in January that he foresees regular air taxi service becoming a reality in the next five years.

On September 12, a Joby-made electric air taxi took a roundtrip flight between Fort Worth Alliance and Dallas Fort Worth International Airport to test flight operations.

The mission was part of a five-day test involving Fort Worth Alliance and DFW Airport flights, and flights over the Fort Worth Stockyards, Toyota Motor North America’s Plano headquarters, and other sites.

A new facility at Fort Worth Alliance will be Joby’s long-term home for regional flight operations.

Building a 'framework' for electric aircraft
TxDOT said Project Nexus is aimed at creating “a scalable system” to connect urban areas, rural communities, and neighboring states as air mobility technology advances.

In a TxDOT release, Marc Williams, the agency’s executive director, said the pilot program will “build a framework for how electric aircraft could one day connect people, goods, and communities across the state.”

Three-phase project will test flight capabilities

Initial flights in the third-year pilot program won’t carry passengers, according to TxDOT. Instead, the flights will gather data, validate air travel routes, and help improve the safety of air mobility technology.

The first phase of the U.S. Department of Transportation’s Project Nexus will feature piloted aircraft such as helicopters and fixed-wing planes. CultureMap previously reported Plano-based VertiPorts by Atlantic, which develops takeoff and landing sites for airplane-helicopter hybrids, would be part of Project Nexus.

The second phase will involve testing airborne medical and cargo logistics. This includes transporting critical medical supplies or donor organs between rural and urban hospitals in the Austin and San Antonio areas.

In the third and final phase, passengers will fly aboard air taxis across the Texas Triangle. Dallas-Fort Worth, Austin, Houston, and San Antonio anchor the triangle.

“In Texas, we don’t wait for the future to arrive, we build it,” Cruz said in the TxDOT release. “The Lone Star State is pushing the boundaries by testing the next generation of aircraft through Project Nexus.”

“These technologies will connect communities, expand access to jobs and services, and strengthen supply chains,” the senator added. “What starts in Texas will help shape the future of aviation throughout the entire country.”

Houston-area NASA contractor plans Nasdaq IPO

going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.
