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.

Hundreds of homes near Houston still under evacuation orders as pipeline fire burns for second day

news update

A pipeline fire that erupted in a suburban Houston neighborhood burned throughout a second day and into the night Tuesday with still no definitive word on when the blaze would finally go out, when nearby residents may be able to return home or why a car drove through a fence and hit a valve before the destructive explosion.

Although the fire was getting smaller, the disruptions caused by the Monday morning explosion in a grassy corridor between a Walmart and a residential neighborhood left some locals increasingly weary. On Tuesday, people could be seen returning to their homes to get clothes and other items before quickly leaving again.

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

Over 36 hours after the blast — which shot towering flames like a blowtorch above the suburbs of Deer Park and La Porte — authorities have provided few details about the circumstances leading up to the explosion.

Investigators said it happened after the driver of a sport utility vehicle went through a fence near the Walmart and struck an above-ground valve. As of Tuesday evening, authorities had not still not identified the driver or said what happened to them.

Deer Park officials have said police and FBI agents found no preliminary evidence to suggest the explosion of the pipeline, which carried natural gas liquids, was a coordinated or terrorist attack. In a statement Monday night, the city said it “appears to be an isolated incident” but officials have not provided details on how they came to that conclusion.

The car was incinerated by the explosion, which scorched the ground across a wide radius, severed power transmission lines, melted playground equipment and ignited some homes.

The valve, which appears to have been protected by a chain-link fence topped with barbed wire, is located within a long grassy field where high-voltage power lines run. Several pipelines run underground.

Authorities evacuated nearly 1,000 homes at one point and ordered people in nearby schools to shelter in place. By Tuesday afternoon that number was down to just over 400.

“The fire is still burning, but the good news is that the pressure within the pipeline is continuously dropping, which means we are getting closer to the fire going out,” Harris County Judge Lina Hidalgo said in a statement.

Operators shut off the flow after the explosion, but Hidalgo has said that 20 miles (32 kilometers) of pipeline stretched between the two closed valves and the chemicals inside had to burn off before the fire would stop.

Robert Hall, a senior advisor at the nonprofit Pipeline Safety Trust, said it’s not surprising that it’s taken more than a day for the material to stop burning.

“You’re talking about 20-inch pipelines and miles between valves, so it takes a long time to burn down,” Hall said.

On Tuesday, the Texas Railroad Commission that regulates the state’s oil and gas industry said its inspectors only will enter the site after it is deemed safe by emergency authorities.

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.

Hall, who previously oversaw pipeline and hazardous materials investigations for the National Transportation Safety Board, said there are few regulations that govern the location of pipelines near homes and businesses.

“That becomes a very local issue, community by community,” Hall said, adding that some jurisdictions require bollards — sturdy pipes filled with concrete — to prevent vehicles from crashing into sensitive infrastructure.

Hidalgo said Tuesday that Energy Transfer, the Dallas-based owner of the pipeline, has said it was working to isolate parts of the pipeline closest to the fire by clamping it on each side.

Energy Transfer did not immediately respond to a question about what safety precautions were in place near the valve.

Hall said regulations from 2022 aimed at reducing deaths and environmental damage from ruptures were geared toward gas lines, not those carrying liquids, and would not have applied to this pipeline. He added that many new safety regulations that have been put in place do not apply retroactively to pre-existing pipelines.

Both Energy Transfer and Harris County Pollution Control were conducting air monitoring in the area and have found no health issues, according to Deer Park officials.

Since leaving home, Reff and her family have been staying in a hotel room paid for by Energy Transfer. But they were eager to return.

“It would be nice to be in our own beds,” she said.

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.

University of Houston secures $3.6M from DOE program to fund sustainable fuel production

freshly granted

A University of Houston-associated project was selected to receive $3.6 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy that aims to transform sustainable fuel production.

Nonprofit research institute SRI is leading the project “Printed Microreactor for Renewable Energy Enabled Fuel Production” or PRIME-Fuel, which will try to develop a modular microreactor technology that converts carbon dioxide into methanol using renewable energy sources with UH contributing research.

“Renewables-to-liquids fuel production has the potential to boost the utility of renewable energy all while helping to lay the groundwork for the Biden-Harris Administration’s goals of creating a clean energy economy,” U.S. Secretary of Energy Jennifer M. Granholm says in an ARPA-E news release.

The project is part of ARPA-E’s $41 million Grid-free Renewable Energy Enabling New Ways to Economical Liquids and Long-term Storage program (or GREENWELLS, for short) that also includes 14 projects to develop technologies that use renewable energy sources to produce sustainable liquid fuels and chemicals, which can be transported and stored similarly to gasoline or oil, according to a news release.

Vemuri Balakotaiah and Praveen Bollini, faculty members of the William A. Brookshire Department of Chemical and Biomolecular Engineering, are co-investigators on the project. Rahul Pandey, is a UH alum, and the senior scientist with SRI and principal investigator on the project.

Teams working on the project will develop systems that use electricity, carbon dioxide and water at renewable energy sites to produce renewable liquid renewable fuels that offer a clean alternative for sectors like transportation. Using cheaper electricity from sources like wind and solar can lower production costs, and create affordable and cleaner long-term energy storage solutions.

“As a proud UH graduate, I have always been aware of the strength of the chemical and biomolecular engineering program at UH and kept myself updated on its cutting-edge research,” Pandey says in a news release. “This project had very specific requirements, including expertise in modeling transients in microreactors and the development of high-performance catalysts. The department excelled in both areas. When I reached out to Dr. Bollini and Dr. Bala, they were eager to collaborate, and everything naturally progressed from there.”

The PRIME-Fuel project will use cutting-edge mathematical modeling and SRI’s proprietary Co-Extrusion printing technology to design and manufacture the microreactor with the ability to continue producing methanol even when the renewable energy supply dips as low as 5 percent capacity. Researchers will develop a microreactor prototype capable of producing 30 MJe/day of methanol while meeting energy efficiency and process yield targets over a three-year span. When scaled up to a 100 megawatts electricity capacity plant, it can be capable of producing 225 tons of methanol per day at a lower cost. The researchers predict five years as a “reasonable” timeline of when this can hit the market.

“What we are building here is a prototype or proof of concept for a platform technology, which has diverse applications in the entire energy and chemicals industry,” Pandey continues. “Right now, we are aiming to produce methanol, but this technology can actually be applied to a much broader set of energy carriers and chemicals.”

Global industrial company Daikin makes deal with Houston Astros on stadium rename

big deal

The Houston Astros' home will get a new name on Jan. 1, becoming Daikin Park under an agreement through the 2039 season the team announced Monday.

The stadium opened as Enron Field in 2000 as part of a 30-year, $100 million agreement but the name was removed in March 2002 following Enron Corp.'s bankruptcy filing and the ballpark briefly became Astros Field.

It was renamed Minute Maid Park in June 2002 as part of a deal with The Minute Maid Co., a Houston-based subsidiary of The Coca-Cola Co. Then-Astros owner Drayton McLane said at the time the agreement was for 28 years and for more than $100 million.

The new deal is with Daikin Comfort Technologies North America Inc., a subsidiary of Daikin Industries Ltd., which is based in Japan and is a leading air conditioning company.

Minute Maid will remain an Astros partner through 2029, the team said.

In August, Daikin, which has its 4.2 million-square-foot Daikin Texas Technology Park in Waller, Texas, partnered with the city of Houston to provide advanced air conditioning and heating solutions to help homeowners with energy efficiency and general comfort. The company pledged install up to 30 horizontal discharge inverter FIT heat pump units over the next three years.
