Spring-based energy giant ExxonMobil has enlisted Air Liquide as a partner for what’s being billed as the world’s largest low-carbon hydrogen project.

The deal will enable transportation of ExxonMobil’s low-carbon hydrogen through Air Liquide’s pipeline network. Furthermore, Air Liquide will build and operate four units to supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen each day for the ExxonMobil project.

Air Liquide’s U.S. headquarters is in Houston.

ExxonMobil’s hydrogen production facility is planned for the company’s 3,400-acre Baytown refining and petrochemical complex. The project is expected to produce 1 billion cubic feet of low-carbon hydrogen daily from natural gas and more than 1 million tons of low-carbon ammonia annually while capturing more than 98 percent of the associated carbon emissions.

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The hydrogen project is expected to come online in 2027 or 2028.

ExxonMobil says using hydrogen to fuel its olefins plant at Baytown could reduce sitewide carbon emissions by as much as 30 percent. Meanwhile, the carbon capture and storage (CSUS) component of the project would be capable of storing 10 million metric tons of carbon each year, the company says.

Why this growing Chilean clean energy company moved its HQ to Houston

future of farming

In Houston, air pollution is usually more of an abstract concept than a harsh reality. But in parts of Chile, the consequences of heating homes with wet wood are catching up to residents.

“Given all the contamination, there are times kids aren’t allowed to go to school. The air pollution is really affecting people’s health,” says Agustín Ríos, COO of Lignium Energy.

Additionally, the methane and nitrous oxide produced by cattle farming are a problem. But Lignium Energy, an international company started in Chile and now headquartered in Houston’s Greentown Labs, has a solution that can solve both problems by upending the latter.

“There’s a lack of solutions with the problem of manure. Methane gases are destroying our planet,” says CEO and co-founder Enrique Guzmán. He goes on to say that most solutions currently being developed are expensive and complex. But not Lignium Energy’s method, invented by co-founder José Antonio Caraball.

Caraball has patented an extraordinarily simple concept. Lignium separates the solid from liquid excretions, then cleans the solid to generate a hay-like biomass. Biomass refers to organic matter that can be used as fuel. What Lignium makes from the cattle evacuations is a clean, odorless and highly calorific biomass.

Essentially, Lignium combats greenhouse gasses with a green fuel that boasts an enviably low carbon footprint. “Our process is very cheap and very simple. That’s why we are a great solution,” explains Guzmán.

Caraball, an industrial engineer, came up with the idea six years ago, says Guzmán. Five years ago, he began working with the company, one year ago, Guzmán and Ríos picked up and moved to Houston.

“We decided to move out of Chile due to market size,” says Ríos. However, the product is already being sold to consumers in its homeland.

Why Houston? The reason was twofold. As an energy company, Ríos says that they wanted to be in “the energy capital of the world.” But Texas is also one of the largest sites of cattle farming on the planet. Lignium prefers to work with farms with more than 500 head to optimize harvesting the waste that becomes biomass.

With that in mind, Lignium has partnered with Southwest Regional Dairy Center in Stephenville, Texas, a little more than an hour southwest of Fort Worth, a town known as the world’s rodeo capital. The facility is associated with Texas A&M, though Guzmán says Lignium is not officially associated with the university.

Guzmán says that the company is currently hiring a team member to help Lignium figure out commercial logistics, as well as four or five other Houstonians who will help them take their product to market in the United States, and eventually around the globe. For now, he predicts that they will be able to sell to consumers in this country by early next year, if not the fourth quarter of 2023.

“We are very committed to the solution because, at the end of the day, if we do good work with the company, we are sure we can give better conditions to the cattle industry,” says Guzmán. “Then we can make a big impact on a real problem.

Houston startup wins funding through new Bezos Earth Fund initiative

global winner

A Houston-based climatech startup is one of the first 16 companies in the world to receive funding through a new partnership between The Bezos Earth Fund and The Earthshot Prize.

Mati Carbon will receive $100,000 through the Bezos Earth Fund’s Acceleration Initiative. The initiative will provide $4.8 million over three years to support climate and nature solutions startups. It's backed by The Bezos Earth Fund, which was founded through a $10 billion gift from Amazon founder Jeff Bezos and aims to "transform the fight against climate change."

The Acceleration Initiative will choose 16 startups each year from The Earthshot Prize’s global pool of nominations that were not selected as finalists. The Earthshot Prize, founded by Prince William, awards £1 million to five energy startups each year over a decade.

"The Earthshot Prize selects 15 finalists each year, but our wider pool of nominations represents a global pipeline of innovators and investable solutions that benefit both people and planet. Collaborating with the Bezos Earth Fund to support additional high-potential solutions is at the heart of commitment to working with partners who share our vision," Jason Knauf, CEO of The Earthshot Prize, said in a news release. "By combining our strengths to support 48 carefully selected grantees from The Earthshot Prize’s pool of nominations, our partnership with the Bezos Earth Fund means we will continue to drive systemic change beyond our annual Prize cycle, delivering real-world impact at scale and speed.”

Mati Carbon was founded in 2022 by co-directors Shantanu Agarwal and Rwitwika Bhattacharya. It removes carbon through its Enhanced Rock Weathering (ERW) program and works with agricultural farms in Africa and India. Mati Carbon says the farmers it partners with are some of the most vulnerable to the impacts of climate change.

"As one of the first 16 organizations selected, this support enables us to expand our operations, move faster and think bigger about the impact we can create," the company shared in a LinkedIn post.

The other grantees from around the world include:

  • Air Protein Inc.
  • Climatenza Solar
  • Instituto Floresta Viva
  • Forum Konservasi Leuser
  • Fundación Rewilding Argentina
  • Hyperion Robotics
  • InPlanet
  • Lasso
  • Mandai Nature
  • MERMAID
  • Asociación Conservacionista Misión Tiburón
  • Simple Planet
  • Snowchange Cooperative
  • tHEMEat Company
  • UP Catalyst

Mati Carbon also won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation, last year.

Texas' oil and gas foundation could boost its geothermal future, UH says

future of geothermal

Equipped with the proper policies and investments, Texas could capitalize on its oil and gas infrastructure and expertise to lead the U.S. in development of advanced geothermal power, a new University of Houston white paper says.

Drilling, reservoir development and subsurface engineering are among the Texas oil and gas industry’s capabilities that could translate to geothermal energy, according to a news release. Furthermore, oil and gas skills, data, technology and supply chains could help make geothermal power more cost-effective.

Up to 80 percent of the investment required for a geothermal project involves capacity and skills that are common in the oil and gas industry, the white paper points out.

Building on its existing oil-and-gas foundation, Texas could help accelerate production of geothermal energy, lower geothermal energy costs and create more jobs in the energy workforce, according to the news release.

The paper also highlights geothermal progress made by Houston-based companies Fervo Energy, Quaise Energy and Sage Geosystems, as well as Canada-based Eavor Technologies Inc.

UH’s Division of Energy published the white paper, Advanced Geothermal: Opportunities and Challenges, in partnership with the C.T. Bauer College of Business’ Gutierrez Energy Management Institute.

“Energy demand, especially electricity demand, is continuing to grow, and we need to develop new low-carbon energy sources to meet those needs,” Greg Bean, executive director of the institute and author of the white paper, said of geothermal’s potential.

HETI leader reflects on four years focused on the energy transition

The View From HETI

It’s hard to believe only four years have passed since I joined the Greater Houston Partnership to lead the Houston Energy Transition Initiative. We talk about COVID years feeling simultaneously like just yesterday and a lifetime ago, and my time at HETI feels quite similar. The energy and climate landscape has evolved dramatically over the last few years, but one constant has endured…Houston remains at the heart of the energy industry.

When I joined HETI at the start of 2022, I could not have imagined the impact we would have over the next four years. Our vision, laid out in 2020 by then Partnership Chair Bobby Tudor, was bold – leverage Houston’s energy leadership to accelerate global solutions for an energy abundant, low-carbon future. Our mission was clear – ensure the long-term economic competitiveness of the Houston region in a changing energy landscape. Our strategy, developed with strong support from McKinsey, was sound – build a coalition of industry, academic and community partners to position Houston as a leading hub for energy and climate innovation, commercialization and economic growth.

And Houston’s energy leaders, across business, academia and community, came together to deliver that strategy. Bobby Tudor’s timely vision created an anchor for Houston’s energy community that allowed us to broaden the energy and climate discussion to one focused on meeting growing energy demand and reducing emissions. That vision was a catalyst for changing the perception of Houston from oil & gas capital to an “all of the above” energy capital with a thriving energy and climate tech innovation ecosystem. Houston is where you can work collaboratively to build new energy value chains and ensure an affordable, secure, and lower emissions energy mix for our region, our country, and the world.

In this fast-moving energy environment, it can be easy to focus on what to do next without taking time to reflect on the work and celebrate the wins. We took the opportunity at the end of 2025 to reflect on five years of impact. As we developed that report, I thought about how fortunate I have been to lead this work for the last four years. HETI’s impact has been incredibly meaningful for our region, our members, and the new companies and founders building the next generation of energy technology and talent. As my time as executive director comes to an end, HETI’s work continues. The need remains clear: more energy, less emissions, and continued collaboration that brings together innovation and infrastructure, policies and markets, and hard tech together with human ingenuity.

As I prepare to hand the reigns to HETI’s new SVP and executive cirector, Sophia Cunningham, at the end of March, I have been reflecting on the impact this role has had on me. Four years ago, I could never have imagined the opportunities, experiences and relationships this role has enabled. I am truly grateful for the support and engagement of Houston’s business and community leaders, the visionary leadership of Bobby Tudor, Scott Nyquist, HETI Members, and the Greater Houston Partnership in creating this initiative at exactly the right moment in time. I am incredibly proud of the HETI and partnership team members who have delivered with purpose and passion, and I greatly appreciate Houston’s energy and climate leaders and champions who have supported my agenda, challenged my thinking, broadened my perspectives, and worked with HETI to demonstrate the power of partnership in developing, innovating and advancing the ideas and technologies needed to meet this challenge for our region and the world.

As excited as I am to see where this next chapter takes me, I am even more excited to see where the work of HETI goes from here. I am still optimistic that the challenge of providing the world with affordable, reliable, and resilient energy while simultaneously reducing emissions is one Houston is uniquely positioned to meet.
