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.

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”

Rice University to lead AI conferences in Paris this spring and summer

where to be

Houston’s own Rice University will host a series of conferences on artificial intelligence in Paris, France, starting this month. The series will tackle the impact and possibilities of AI in fields like econometrics and online privacy security.

“Artificial intelligence is transforming the global economy and raising profound questions about how technology intersects with society,” Caroline Levander, Rice’s vice president for global strategy, said in a news release. “By convening scholars from multiple disciplines and countries in Paris, Rice is helping shape the international conversation about how AI should be developed, governed and used.”

The four conferences in Paris aim for a multi-disciplinary approach that tackles aspects of AI from diverging angles. The conferences come as part of Rice’s increased partnership with French researchers at the Université Paris Sciences & Lettres. The two institutions have formed a binary star system of academic sharing and support.

“Paris has quickly become one of the most important global hubs for artificial intelligence research, entrepreneurship and policy,” Levander said. “For Rice, having a presence in the city allows our scholars to engage directly with that ecosystem while building collaborations that connect Europe and the United States around the future of AI.”

The conferences will be held at the Rice Global Paris Center. Topics scheduled are:

Emerging Topics in Operations Management: Platforms, Blockchains and AI

April 27-29

This conference will focus on how companies like Uber, Airbnb, Spotify, and DoorDash can use blockchain ledgers to deliver goods and services more transparently. It will also look at tokenized incentives, presumably forms of cryptocurrency and non-fungible tokens in the app space.

Econometrics and AI

May 5-7

This conference will explore how AI can be used in various economic statistical models and practices.

Human Flourishing in the Age of AI

June 3-5

This conference will be a collaboration between engineers and philosophers about the ethics and impact of AI on the lives of its users.

On the Crossroads of AI and Society: Incentives, Privacy and Fairness

July 15-16

This conference will consider how to stakeholders can ensure AI’s actions most benefit people, particularly in the fields of healthcare education, energy and public policy.

Houston claims 19% of Texas’ new live-work-play growth

by the numbers

In Texas, Houston is a big player in the live-work-play real estate movement.

A new 21-city analysis from coworking marketplace CoworkingCafe shows the Houston area added five live-work-play projects—mixed-use developments with residential, office and recreational components—over the past decade.

From 2016 to 2025, Houston accounted for 19 percent of Texas’ new live-work-play inventory, the analysis shows. Among the new local developments were Arrive Upper Kirby, St. Andrie, and The Laura:

  • Arrive Upper Kirby, which was sold in 2021 for $182 million, offers more than 61,000 square feet of retail and restaurant space adjacent to apartments and offices. The 13-story, 265,000-square-foot project was completed in 2017.
  • St. Andrie, a 32-acre, mixed-use community, was completed in 2019. The apartment-anchored development includes an H-E-B grocery store and 37,000 square feet of office space.
  • The Laura, spanning 110,000 square feet, was completed in 2023. Among the apartment complex’s amenities is a coworking space.

According to Northspyre, a software provider for real estate developers, live-work-play projects enable people to meet their needs, such as housing, workplaces, stores, restaurants, and recreation facilities, in a single place.

A total of 542 live-work-play developments opened between 2016 and 2025 in the 21 cities, with another 69 in the pipeline for 2026, CoworkingCafe says. Among major markets, New York City made up the largest share (119) of new live-work-play developments from 2016 to 2025.

The Houston area’s five projects were built in 2018, 2019, 2020, 2024, and 2025, CoworkingCafe data indicates, with another project scheduled for completion next year. The Greater Houston Partnership recently highlighted four mixed-use projects taking shape in the region, but only one of them is scheduled to be finished in 2027. It can take two to five years or more to complete a mixed-use development.

Of the five Houston developments finished in the past decade, 56 percent of the space went toward multifamily units, 29 percent toward offices, and 16 percent toward retail, CoworkingCafe says.

As noted by the Houston-Galveston Area Council, economic development in the 21st century “is about cultivating quality live-work-play environments that attract, retain, and grow a diverse and skilled population. Employers and businesses are increasingly choosing to make long-term investments in places that connect and engage people to strengthen economic competitiveness and promote innovation.”

With eight completed projects, Austin led construction of live-work-play developments in Texas from 2016 to 2025, according to CoworkingCafe. Dallas, which welcomed five live-work-play developments during that period, tied with Houston. San Antonio data wasn’t available.
