Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.

Energy co. makes $100,000 donation to Houston hospital

energizing ALS research

Where do energy transition and life-saving medicine meet? In Texas, of course.

Energy Transfer, a Dallas-based midstream energy company, just donated $100,000 to Houston Methodist. The grant is part of a $200,000 gift that has spanned the past two years. The goal? To eradicate the neurological disorder, ALS (amyotrophic lateral sclerosis). There is currently no cure for ALS. For roughly 90 percent of patients, there’s no known genetic cause, meaning the disease can strike anyone.

Houston Methodist currently has numerous clinical trials taking place with the goal to slow or halt the progression of the degenerative ailment.

“Every dollar donated to ALS research is a beacon of hope for those battling the disease,” said Chris Curia, executive vice president and chief human resources officer at Energy Transfer. “Those affected by ALS deserve a chance at a better life. We are hopeful this donation brings us one step closer to a world without this disease.”

Houston Methodist is home to the first multidisciplinary care clinic for ALS patients in the region and is actively engaged in both clinical and basic scientific research to support people battling ALS.

“We appreciate Energy Transfer’s generosity in our efforts to improve the quality of life and to provide hope for ALS patients and their families. Their continued commitment to Houston Methodist’s ongoing ALS research is truly transformational,” says Stanley H. Appel, M.D., a pioneering neurologist at Houston Methodist whose lab focuses on neurodegenerative diseases, including ALS.

Energy Transfer’s gift will help to support one particularly promising trial of a combination therapy that is currently moving into Phase 2. In its first phase, the therapy was found to safely slow disease progression in four ALS patients over a six-month period. Those patients had no significant progression of their disease during the trial. Prior to receiving the therapy, each of the patients had reported declining abilities to perform daily tasks.

Energy Transfer’s good deed could mean the world not only to patients at Houston Methodist, but to ending ALS altogether.

How this Houston hospital is leading sustainable health care

seeing green

The United States health care sector contributes around 8.5 percent of greenhouse gas emissions, and one Houston hospital is committed to doing its part in reducing the industry's carbon footprint.

Houston Methodist, which recently opened a new tech hub in the Ion in midtown, has put in place several initiatives that reflect a more sustainable future for health care. The organization, which has seven hospitals in the Houston area, revealed some of these ongoing and planned projects at a recent event.

"Houston Methodist is always looking ahead on ways — not only of how we are taking care of patients — but what are we doing to create this environment and making the right efforts for sustainability, which we should all be doing," Michelle Stansbury, vice president of innovation and IT applications at Houston Methodist, says on this week's episode of the Houston Innovators Podcast. "We have to protect this environment that we have or it may not be the same for our children going forward."

The hospital system is currently in the design phase for installing solar panels on the Josie Roberts Administration Building in the Texas Medical Center. This project, in partnership with Houston Methodist's Energy and Facilities workgroup, will be the first step toward renewable energy consumption for the hospital.

Houston Methodist has already rolled out food composting initiatives at its locations in Sugar Land, The Woodlands, and Willowbrook locations — with plans for additional campuses to follow. According to a presentation from Jason Fischer, director of the Office of Sustainability at Methodist, the hospital system has already diverted nearly 100,000 lbs. of food waste from landfills.

Preventing waste recycling or reusing items is another focus of Houston Methodist, Stansbury says, from creating a workflow that enables reusing items that are able to be sanitized rather than thrown away to sustainably getting rid of expired materials. The U.S. has rules about the shelf lives of health care products, but other countries don't have as strict of mandates.

"We're sending (supplies) to other countries that can still use these products," Stansbury explains. "Knowing that we're helping to care for other individuals, to me I think it's very valuable. Other countries don't have the resources that the United States does."

Another notable initiative is incorporating greenspace for patients to enjoy. Houston Methodist is currently in construction on a 26-story hospital tower in the Texas Medical Center that will feature the Centennial Rooftop Garden on the 14th floor.

The Houston Methodist's sustainability team has several other initiatives both ongoing and in the works. More information is available on the hospital's website.

New Rice study details how carbon capture could reduce AI data center emissions

by the numbers

A new study out of Rice University points to carbon capture and storage methods as pivotal solutions to addressing emissions from AI-driven data centers.

The study was authored by Hon Chung Lau, an adjunct professor in the Department of Chemical and Biomolecular Engineering at Rice University and founder of Low Carbon Energies LLC, and Steve C. Tsai, an energy transition consultant at Low Carbon Energies LLC, and published in the journal Energy & Fuels.

According to the study, U.S. data center power capacity could more than quadruple in five years, growing from 40 gigawatts in 2025 to 169 gigawatts by 2030. Without proper regulation of emissions, the report estimates that carbon dioxide produced by fossil-fuel power plants supplying electricity to data centers could grow at the same scale, increasing from 90 million metric tons to more than 404 million metric tons over the same time period.

The researchers analyzed publicly available data on announced U.S. data centers, which included energy sources, locations, and projected power capacity before estimating data center-related carbon emissions based on each state’s electricity mix. From there, they examined whether those emissions could be captured and stored underground in saline aquifers.

The team estimates that 34 states have enough saline aquifer storage capacity to store more than 100 years of projected data center-related carbon dioxide emissions beyond 2030. Aquifers could store an estimated 59 million metric tons of data center-related carbon dioxide, or about 66 percent of the sector’s emissions in 2025. However, that calculation could grow to 299 million metric tons, or about 74 percent of projected data center-related emissions by 2030.

The researchers found that more than 90 percent of data center-related carbon dioxide emissions could potentially be mitigated through carbon capture and storage when out-of-state storage options are included, even though they note that carbon capture isn’t the only solution.

“It does show that the geology exists to make a meaningful impact, especially in states where data center growth is strongest,” Lau said in a news release.

Rapid growth in states including Texas, Virginia, Pennsylvania, Ohio, Arizona, Colorado, Utah and Illinois was considered in the study. According to the findings, Texas would need to add 25 gigawatts of power capacity by 2030 to meet projected data center demand, as data centers require reliable electricity 24/7.

“Data centers are becoming one of the defining energy challenges of the AI era,” Lau added in the news release. “The question is not only whether we can build enough computing infrastructure, but whether we can power it in a way that is reliable, affordable and compatible with decarbonization goals.”

Shell strikes $1.8B deal to offload solar and wind assets in India

Renewable Exit

Reflecting its ongoing de-emphasis of renewable energy, oil and gas giant Shell has agreed to sell its solar and wind power business in India for $1.8 billion.

Aditya Birla Renewables Ltd. (ABRen) is the pending buyer of Solenergi Power Private Ltd., including the Sprng Energy group of companies. Sprng Energy develops, owns and operates utility-scale solar and wind power facilities in India.

Shell, whose U.S. headquarters is in Houston, acquired Solenergi in 2022 for $1.55 billion.

ABRen is Aditya Birla Group’s renewable energy platform. Global Infrastructure Partners, part of asset manager BlackRock, is a strategic investor in ABRen. ABRen develops and operates solar, wind, hybrid and battery storage projects in India.

“This agreement reflects Shell’s continued focus on adjusting the portfolio in our power business,” Machteld de Haan, Shell’s president of downstream, renewables and energy solutions, said in a news release. “We are high-grading our power portfolio and recycling capital in service of our asset-backed trading strategy … This is another step in building a more focused, competitive, and resilient business while improving returns year on year towards 2030.”

Under Wael Sawan, who was named CEO of Shell in 2023, the company has moved away from large-scale, low-yield green energy projects to concentrate on high-margin sectors. Those sectors include natural gas, LNG, deep-water drilling and global energy trading.

The Solenergi deal, expected to close by the end of this year, signals yet another move in Shell’s reassessment of its renewables business. The company has said it will no longer invest in offshore wind projects, but it remains committed to becoming a net-zero emissions business by 2050.

Shell said India remains an important market. In India, Shell offers LNG supply and regasification for downstream users, and also operates Shell Mobility and Shell Lubricants.

The proposed sale of the Indian renewables business continues Shell’s decreasing focus on renewables. In October, Shell exited Atlantic Shores Offshore Wind, a 50-50 joint venture created to offshore wind projects off the coast of New Jersey and New York.

Shell has declared it will not make new investments in offshore wind generation, favoring existing ventures and the expansion of EV charging infrastructure.

The company also announced plans to shut down its Volta C electric vehicle charging business in August 2025.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
