A pipeline fire that burned in a Houston suburb for four days finally went out Thursday as authorities announced a criminal investigation into the blaze that had roared into a towering flame, forcing neighborhoods to evacuate and melting parts of nearby cars.

Before the fire fully stopped Thursday evening, officials announced that human remains were found in an SUV that had been next to the flame since the explosion happened Monday. Investigators say the fire began after the driver of that car went through a fence alongside a Walmart parking lot and struck an above-ground valve.

Officials in Deer Park, where the explosion occurred, described the crash as an accident, and said police and local FBI agents have not found evidence of a coordinated or terrorist attack.

“This has developed into a criminal investigation and will be actively ongoing until more information is available,” the city said in a statement late Thursday.

As authorities worked to identify who had driven the vehicle, residents who were forced to flee the towering blaze returned to assess the damage on Thursday. They found mailboxes and vehicles partially melted by the intense heat, a neighborhood park charred and destroyed and fences burned to the ground.

“Devastated, upset, scared. We don’t know what we’re going to do now,” said Diane Hutto, 51, after finding her home severely damaged by water that firefighters poured on it to keep it from catching fire. Hutto’s home is located only a few hundred feet from the pipeline.

Before the fire went out, its reduced size meant police finally had access to the area around the pipeline. Investigators removed the white SUV and towed it away Thursday morning.

While medical examiners with Harris County were processing the vehicle, they recovered and removed human remains found inside, Deer Park officials said in a statement.

Officials say the underground pipeline, which runs under high-voltage power lines in a grassy corridor between the Walmart and a residential neighborhood, was damaged when the SUV driver left the store’s parking lot, entered the wide grassy area and went through a fence surrounding the valve equipment.

But authorities have offered few details on what caused the vehicle to crash through the fence and hit the pipeline valve.

Energy Transfer, the Dallas-based company that owns the pipeline, on Wednesday called it an accident. Deer Park officials said preliminary investigations by police and FBI agents found no evidence of a terrorist attack.

The pipeline is a 20-inch-wide (50-centimeter-wide) conduit that runs for miles through the Houston area. It carries natural gas liquids through Deer Park and La Porte, both of which are southeast of Houston.

Authorities evacuated nearly 1,000 homes at one point and ordered people in nearby schools to shelter in place. Officials began letting residents return to their homes on Wednesday evening.

Hutto said Thursday the fire incinerated her home’s backyard fence and partially melted a small shed where her husband stored his lawnmower. Inside the home, mold and mildew were starting to set in from the water damage, and part of the ceiling in her daughter's bedroom had collapsed.

“Everything is just soaking wet,” she said. “It smells bad. I don’t think there’s really anything we can salvage at this point.”

Across the street, Robert Blair found minor damage when he returned to his home Thursday morning. It included broken and cracked windows and a window screen and irrigation system pipes that had been melted by the heat.

“We were very lucky here. It could have been worse,” said Blair, 67.

The pipeline’s valve equipment appears to have been protected by a chain-link fence topped with barbed wire. Energy Transfer has not responded to questions about any other safety protections that were in place.

Harris County Judge Lina Hidalgo, the county’s top elected official, said Thursday that officials will look at whether they can require companies like Energy Transfer to install better security measures, including concrete structures around pipelines and their aboveground valves.

“If they had that around it, I don’t think this would have happened,” Blair said.

Energy Transfer and Harris County officials have said that air quality monitoring showed no immediate risk to individuals, despite the huge tower of billowing flame that shot hundreds of feet into the air when the fire first began, creating thick black smoke that hovered over the area.

Houston, Texas’ largest city, is the nation’s petrochemical heartland and is home to a cluster of refineries and plants and thousands of miles of pipelines. Explosions and fires are a familiar sight in the area, including some that have been deadly, raising recurring questions about the adequacy of industry efforts to protect the public and the environment.

Hidalgo said some residents she spoke with told her they don’t feel safe living in the area after this week’s fire.

Hutto, whose husband works in a petrochemical plant, said living near such facilities has always been a concern, but this week’s fire has changed things for her.

“I don’t think I want to live here anymore. I’m just too scared to stay here,” Hutto said.

What to know about the Houston pipeline fire — how it started, pollution impact, and more

latest update

A pipeline fire that forced hundreds of people to flee their homes in the Houston suburbs burned for a third day Wednesday, with officials saying they don't expect it to be extinguished until sometime Thursday evening.

Officials said residents who had to evacuate would be allowed to return to their homes starting Wednesday evening.

Authorities have offered few details about what prompted the driver of an SUV to hit an aboveground valve on the pipeline on Monday, sparking the blaze.

Here are some things to know about the situation with the pipeline fire:

What caused the fire?

Officials say the underground pipeline, which runs under high-voltage power lines in a grassy corridor between a Walmart and a residential neighborhood in Deer Park, was damaged when the SUV driver left the store's parking lot, entered the wide grassy area and went through a fence surrounding the valve equipment.

Authorities have offered few details on what caused the vehicle to hit the pipeline valve, the identity of the driver or what happened to them. The pipeline company on Wednesday called it an accident. Deer Park officials said preliminary investigations by police and FBI agents found no evidence of a terrorist attack.

Deer Park police won't be able to reach the burned-out vehicle until the flame has been extinguished. Once the area is safe, the department will be able to continue its investigation and confirm specifics, city spokesperson Kaitlyn Bluejacket said in an email Wednesday.

The valve equipment appears to have been protected by a chain-link fence topped with barbed wire. The pipeline's operator has not responded to questions about any other safety protections that were in place.

Who is responsible for the pipeline?

Energy Transfer is the Dallas-based owner of the pipeline, a 20-inch-wide (50-centemeter-wide) conduit that runs for miles through the Houston area.

It carries natural gas liquids through the suburbs of Deer Park and La Porte, both of which are southeast of Houston. Energy Transfer said the fire had diminished overnight and was continuing to “safely burn itself out” on Wednesday.

Energy Transfer also built the Dakota Access Pipeline, which has been at the center of protests and legal battles. The company’s executive chairman, Kelcy Warren, has given millions of dollars in campaign contributions to Republican Texas Gov. Greg Abbott.

What's being done to extinguish the fire?

Energy Transfer said its crews were working Wednesday to install specialized isolation equipment on both sides of the damaged section that will help extinguish the fire.

Once the equipment is installed, which could take several hours of welding, the isolated section of the pipeline will be purged with nitrogen, which will extinguish the fire, company and local officials said. After that, damaged components can be repaired.

“The safest way to manage this process is to let the products burn off,” Energy Transfer said.

Late Wednesday afternoon, Deer Park officials said repair work on the pipeline to help speed up the process to put out the fire wasn't expected to be completed until 6 p.m. on Thursday. Once finished, the fire was anticipated to be extinguished within two to three hours.

How have residents been impacted?

Authorities evacuated nearly 1,000 homes at one point and ordered people in nearby schools to shelter in place. Officials said that starting at 6 p.m. on Wednesday, residents in Deer Park and La Porte who had to evacuate would be allowed to return to their homes. A portion of a highway near the pipeline would remain closed, officials said.

Hundreds of customers lost power. Officials said Wednesday afternoon that only two customers remained without electricity in the Deer Park and La Porte area. Repairs to all of the power distribution lines affected by the fire had been completed.

Deer Park's statement said Energy Transfer was “prioritizing the safety of the community and environment as it implements its emergency response plan.”

“We appreciate the patience and understanding of all residents during this ongoing situation,” Deer Park officials said.

By late Tuesday, about 400 evacuees remained, and some expressed frustration over being forced to quickly flee and not being given any timeline for when they will be able to return.

“We literally walked out with the clothes on our backs, the pets, and just left the neighborhood with no idea where we were going,” said Kristina Reff, who lives near the fire. “That was frustrating.”

What about pollution from the fire?

Energy Transfer and Harris County officials have said that air quality monitoring shows no immediate risk to individuals, despite the huge tower of billowing flame that shot hundreds of feet into the air, creating thick black smoke that hovered over the area.

Houston is the nation’s petrochemical heartland and is home to a cluster of refineries and plants and thousands of miles of pipelines. Explosions and fires are a familiar sight, and some have been deadly, raising recurring questions about industry efforts to protect the public and the environment.

Fervo Energy leads Time’s top green tech companies of 2026

top spot

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

  • No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
  • No. 71 Plus Power, which develops, owns and operates battery energy storage systems
  • No. 98 Utility Global, whose technology enables industrial decarbonization
  • No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
  • No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

  • The 2025 Houston Innovation Awards named it Scaleup of the Year
  • MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
  • Time named Fervo one of the 100 Most Influential Companies of 2025
  • Fervo was hailed as the Global Cleantech Group 100 North American Company of the Year
  • Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span
Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

3 strategies to strengthen the Gulf Coast as a global energy hub

The View from HETI

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone.

This unmatched concentration of refining, petrochemical manufacturing, pipelines, ports, and technical talent makes the Gulf Coast one of the most critical energy hubs in the world. But maintaining that leadership in a rapidly evolving global market will require intentional collaboration, faster technology commercialization, and strengthened supply chain resilience.

In fall 2025, the Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) convened national laboratories, Gulf Coast universities, and industry leaders to examine how to reinforce the region’s long-term competitiveness. Participants included Argonne, Oak Ridge, Lawrence Berkeley, the National Energy Technology Laboratory (NETL), and the National Laboratory of the Rockies, alongside Gulf Coast academic institutions and energy and chemical companies. Here are the key findings and takeaways from the workshop.

1. Supply Chain Resilience Requires Structured Industry–Lab Collaboration

Resilience—diversity of supply, operational flexibility, and rapid recovery—was a recurring theme. Recent disruptions exposed vulnerabilities in tightly interconnected energy and manufacturing systems.

National laboratories provide capabilities that complement Gulf Coast industrial scale, particularly at early and mid technology readiness levels (TRLs 1–7), before full commercial deployment. Examples include:

  • Advanced manufacturing and AI-enabled validation of critical components (Oak Ridge).
  • Materials scale-up and techno-economic modeling to move from lab discovery to industrial relevance (Argonne).
  • Pilot-scale testing for severe-service alloys, chemical conversion, and process innovation (NETL).
  • Integrated energy systems modeling to assess grid resilience and system disruptions (National Laboratory of the Rockies).

Recommendation: Organize targeted Gulf Coast industry missions to national laboratories focused on critical supply chains—power equipment, high-heat industrial processes, novel catalysts, refining, and grid infrastructure—to identify joint development opportunities and reduce time to commercialization.

2. Modeling, AI, and Open-Access Platforms Can Bridge the Technology Gap

A persistent barrier to innovation is the gap between scientific discovery, applied development, and commercial deployment. Universities often operate at TRLs 1–3, national labs at 1–7, and industry at 7–9. Bridging these silos requires shared modeling tools, high-performance computing, and structured feedback loops.

National labs maintain open-access platforms capable of:

  • Simulating grid expansion, investment, and dispatch decisions.
  • Modeling cradle-to-gate industrial material flows.
  • Optimizing complex energy and chemical systems.
  • De-risking carbon capture, critical mineral recovery, and advanced manufacturing integration.

Recommendation: HETI should convene structured training and feedback sessions on these public modeling platforms—ensuring Gulf Coast industry can apply, improve, and help guide further development of tools critical to regional competitiveness. Federal initiatives such as the Genesis Mission, focused on AI-accelerated scientific discovery, further expand opportunities for Gulf Coast participation.

3. Time to Commercialization Is the Ultimate Competitive Metric

The lithium-ion battery is a cautionary example: while pioneered in U.S. labs, large-scale manufacturing leadership shifted overseas. Without strategic intervention, U.S. firms are projected to capture less than 30% of domestic lithium battery cell value by 2030.

Successful DOE-backed consortium models show that mission-aligned, multi-partner collaboration reduces development timelines and strengthens domestic manufacturing know-how. However, public–private partnership mechanisms such as CRADAs and Strategic Partnership Projects can be time-intensive.

Recommendation: The Gulf Coast should actively engage DOE and national laboratories to streamline public–private partnership pathways, improve intellectual property clarity, and expand industry access to laboratory infrastructure.

The Path Forward: A Gulf Coast Consortium Model
The workshop’s central conclusion was clear: the Gulf Coast should formalize collaboration through a regional industry–academia–laboratory consortium.

Such a model could:

  • Co-locate national lab researchers within the region.
  • Share modeling data and analytical capabilities.
  • Establish open-access pilot facilities that complement lab infrastructure.
  • Harmonize IP frameworks to accelerate licensing and deployment.

With its dense industrial ecosystem, technical workforce, and decision-making concentration, the Gulf Coast is uniquely positioned to serve as a national demonstration hub for advanced energy and chemical manufacturing.

If industry, universities, and national laboratories align around a shared regional strategy, the Gulf Coast can:

  • Accelerate commercialization timelines.
  • Strengthen critical supply chains.
  • Unleash a world-class technical workforce.
  • Reinforce U.S. leadership in strategic energy and chemical sectors.
