Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

  • Advance work on the mitigation of methane emissions
  • Set up internship programs
  • Boost workforce development
  • Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.

New Mexico court upholds emissions crackdown impacting oil, gas operations along Texas border

eyes on the west

The New Mexico Court of Appeals has upheld regulations aimed at cracking down on emissions in one of the nation’s top-producing oil and gas states.

The case centered on a rule adopted in 2022 by state regulators that called for curbing the pollutants that chemically react in the presence of sunlight to create ground-level ozone, commonly known as smog. High ozone levels can cause respiratory problems, including asthma and chronic bronchitis.

Democratic Gov. Michelle Lujan Grisham's administration has long argued that the adoption of the ozone precursor rule along with regulations to limit methane emissions from the industry were necessary to combat climate change and meet federal clean air standards.

New Mexico Environment Secretary James Kenney said the court's decision on Wednesday affirmed that the rule was properly developed and there was substantial evidence to back up its approval by regulators.

“These rules aren’t going anywhere,” Kenney said in a statement to The New Mexican, suggesting that the industry stop spending resources on legal challenges and start working to comply with New Mexico's requirements.

The Independent Petroleum Association of New Mexico had argued in its appeal that the rule disproportionately affected independent operators.

“The administration needs to stop its ‘death by a thousand cuts’ hostility to the smaller, family-owned, New Mexico-based operators,” the group's executive director, Jim Winchester, said in an email to the newspaper.

The group is considering its legal options.

Under the rule, oil and gas operators must monitor emissions for smog-causing pollutants — nitrogen oxides and volatile organic compounds — and regularly check for and fix leaks.

The rule applies to eight counties — Chaves, Doña Ana, Eddy, Lea, Rio Arriba, Sandoval, San Juan and Valencia — where ozone pollutants have reached at least 95% of the federal ambient air quality standard. Some of those counties include production hot spots within the San Juan Basin in northwestern New Mexico and the Permian Basin, which straddles the New Mexico-Texas line.

The industry group had argued that Chaves and Rio Arriba counties shouldn’t be included. The court disagreed, saying those counties are located within broader geographic regions that did hit that 95% threshold.

New York financial firm partners with Houston O&G co. to turn natural gas into blue hydrogen

teamwork

A new partnership between an energy and sustainability investor and a Houston-based company that focuses on cleaner solutions in the oil and gas industry will look into turning stranded natural gas into blue hydrogen.

New York-based Double Zero Holdings and SJ Environmental announced their new partnership this week in an effort to move forward the energy transition. According to the companies, stranded natural gas — mostly methane — usually remains unused where it is not economically viable to transport. By turning these gasses into into blue hydrogen, "the partnership mitigates methane and CO2 emissions while producing hydrogen—a clean fuel that could revolutionize multiple industries," reads the news release.

The initiative will use existing technologies, which can be reduced to the size of a standard shipping container, per the release.

"We're thrilled to partner with SJ Environmental to tackle one of the most pressing environmental issues today," Raja Ramachandran, managing partner of Double Zero Holdings, says in the release. "This collaboration allows us to turn stranded natural gas—a significant environmental liability—into a valuable resource, supporting the global shift toward cleaner energy."

The plan is to lower the amount of natural gas left wasted and provide a low-carbon alternative across transportation, manufacturing, and power generation.

"Our collaboration with Double Zero Holdings reflects our commitment to innovative, sustainable solutions," SJ Environmental Director John Chappell adds. "Together, we're setting a new standard for energy production, delivering hydrogen and food-grade CO₂ where natural gas would typically be flared."

Baker Hughes, bp team up on flare emissions monitoring tech

partnerships

Two energy companies with Houston headquarters are collaborating on flare emissions monitoring.

According to a news release, bp is now using Baker Hughes emissions abatement technology, flare.IQ, to quantify "methane emissions from its flares, a new application for the upstream oil and gas sector." The statement goes on to explain that the industry doesn't have a to methane emission quantifying, and that bp ad Baker Hughes has facilitated a large, full-scale series of studies on the technology.

Now, bp is utilizing 65 flares across seven regions to reduce emissions.

“bp’s transformation is underway, turning strategy into action through delivery of our targets and aims. We don’t have all the answers, and we certainly can’t do this on our own," Fawaz Bitar, bp senior vice president of Health Safety Environment & Carbon, says in the release. "Through our long-standing partnership with Baker Hughes, we have progressed technology and implemented methane quantification for oil and gas flares, helping us to achieve the first milestone of our Aim 4. We continue to look at opportunities like this, where we can collaborate across the industry to find solutions to our biggest challenges."

The flare.IQ technology is a part of Baker Hughes’ Panametrics product line portfolio, and it builds on 40 years of ultrasonic flare metering technology experience. The advanced analytics platform provides operators with real-time, decision-making data.

“Our collaboration with bp is an important landmark and a further illustration that technology is a key enabler for addressing the energy trilemma of security, sustainability and affordability,” Ganesh Ramaswamy, executive vice president of Industrial & Energy Technology at Baker Hughes, says in the release. “As a leader in developing climate technology solutions, such as our flare.IQ emissions monitoring and abatement technology, cooperations like the one we have with bp are key to testing and validating in the field solutions that can enable operators to achieve emissions reduction goals efficiently and economically.”

US energy industry methane emissions are triple what government thinks, study finds

by the numbers

American oil and natural gas wells, pipelines and compressors are spewing three times the amount of the potent heat-trapping gas methane as the government thinks, causing $9.3 billion in yearly climate damage, a new comprehensive study calculates.

But because more than half of these methane emissions are coming from a tiny number of oil and gas sites, 1% or less, this means the problem is both worse than the government thought but also fairly fixable, said the lead author of a study in Wednesday's journal Nature.

The same issue is happening globally. Large methane emissions events around the world detected by satellites grew 50% in 2023 compared to 2022 with more than 5 million metric tons spotted in major fossil fuel leaks, the International Energy Agency reported Wednesday in their Global Methane Tracker 2024. World methane emissions rose slightly in 2023 to 120 million metric tons, the report said.

“This is really an opportunity to cut emissions quite rapidly with targeted efforts at these highest emitting sites,” said lead author Evan Sherwin, an energy and policy analyst at the U.S. Department of Energy's Lawrence Berkeley National Lab who wrote the study while at Stanford University. “If we can get this roughly 1% of sites under control, then we're halfway there because that's about half of the emissions in most cases.”

Sherwin said the fugitive emissions come throughout the oil and gas production and delivery system, starting with gas flaring. That's when firms release natural gas to the air or burn it instead of capturing the gas that comes out of energy extraction. There's also substantial leaks throughout the rest of the system, including tanks, compressors and pipelines, he said.

“It's actually straightforward to fix,” Sherwin said.

In general about 3% of the U.S. gas produced goes wasted into the air, compared to the Environmental Protection Agency figures of 1%, the study found. Sherwin said that's a substantial amount, about 6.2 million tons per hour in leaks measured over the daytime. It could be lower at night, but they don't have those measurements.

The study gets that figure using one million anonymized measurements from airplanes that flew over 52% of American oil wells and 29% of gas production and delivery system sites over a decade. Sherwin said the 3% leak figure is the average for the six regions they looked at and they did not calculate a national average.

Methane over a two-decade period traps about 80 times more heat than carbon dioxide, but only lasts in the atmosphere for about a decade instead of hundreds of years like carbon dioxide, according to the EPA.

About 30% of the world's warming since pre-industrial times comes from methane emissions, said IEA energy supply unit head Christophe McGlade. The United States is the No. 1 oil and gas production methane emitter, with China polluting even more methane from coal, he said.

Last December, the Biden administration issued a new rule forcing the U.S. oil and natural gas industry to cut its methane emissions. At the same time at the United Nations climate negotiations in Dubai, 50 oil companies around the world pledged to reach near zero methane emissions and end routine flaring in operations by 2030. That Dubai agreement would trim about one-tenth of a degree Celsius, nearly two-tenths of a degree Fahrenheit, from future warming, a prominent climate scientist told The Associated Press.

Monitoring methane from above, instead of at the sites or relying on company estimates, is a growing trend. Earlier this month the market-based Environmental Defense Fund and others launched MethaneSAT into orbit. For energy companies, the lost methane is valuable with Sherwin's study estimate it is worth about $1 billion a year.

About 40% of the global methane emissions from oil, gas and coal could have been avoided at no extra cost, which is “a massive missed opportunity,” IEA's McGlade said. The IEA report said if countries do what they promised in Dubai they could cut half of the global methane pollution by 2030, but actions put in place so far only would trim 20% instead, “a very large gap between emissions and actions,” McGlade said.

“It is critical to reduce methane emissions if the world is to meet climate targets,” said Cornell University methane researcher Robert Horwath, who wasn't part of Sherwin's study.

“Their analysis makes sense and is the most comprehensive study by far out there on the topic,” said Howarth, who is updating figures in a forthcoming study to incorporate the new data.

The overflight data shows the biggest leaks are in the Permian basin of Texas and New Mexico.

“It's a region of rapid growth, primarily driven by oil production,” Sherwin said. “So when the drilling happens, both oil and gas comes out, but the main thing that the companies want to sell in most cases was the oil. And there wasn't enough pipeline capacity to take the gas away” so it spewed into the air instead.

Contrast that with tiny leak rates found in drilling in the Denver region and the Pennsylvania area. Denver leaks are so low because of local strictly enforced regulations and Pennsylvania is more gas-oriented, Sherwin said.

This shows a real problem with what National Oceanic and Atmospheric Association methane-monitoring scientist Gabrielle Petron calls “super-emitters."

“Reliably detecting and fixing super-emitters is a low hanging fruit to reduce real life greenhouse gas emissions,” Petron, who wasn't part of Sherwin's study, said. “This is very important because these super-emitter emissions are ignored by most ‘official’ accounting.”

Stanford University climate scientist Rob Jackson, who also wasn't part of the study, said, “a few facilities are poisoning the air for everyone.”

“For more than a decade, we’ve been showing that the industry emits far more methane than they or government agencies admit," Jackson said. “This study is capstone evidence. And yet nothing changes.”

EPA sets out rules for proposed 'methane fee' for waste generated by oil and natural gas companies

pollution deterrent

Oil and natural gas companies for the first time would have to pay a fee for methane emissions that exceed certain levels under a rule proposed Friday by the Biden administration.

The proposed Environmental Protection Agency rule follows through on a directive from Congress included in the 2022 climate law. The new fee is intended to encourage industry to adopt best practices that reduce emissions of methane and thereby avoid paying.

Methane is a climate “super pollutant” that is more potent in the short term than carbon dioxide and is responsible for about one-third of greenhouse gas emissions. The oil and natural gas sector is the largest industrial source of methane emissions in the United States, and advocates say reduction of methane emissions is an important way to slow climate change.

Excess methane produced this year would result in a fee of $900 per ton, with fees rising to $1,500 per ton by 2026.

EPA Administrator Michael Regan said the proposed fee would work in tandem with a final rule on methane emissions EPA announced last month. The fee, formally known as the Methane Emissions Reduction Program, will encourage early deployment of available technologies to reduce methane emissions and other harmful air pollutants before the new standards take effect, he said.

The rule announced in December includes a two-year phase-in period for companies to eliminate routine flaring of natural gas from new oil wells.

“EPA is delivering on a comprehensive strategy to reduce wasteful methane emissions that endanger communities and fuel the climate crisis,” Regan said in a statement. When finalized later this year, the proposed methane fee will set technology standards that will “incentivize industry innovation'' and spur action to reduce pollution, he said.

Leading oil and gas companies already meet or exceed performance levels set by Congress under the climate law, meaning they will not have to pay the proposed fee, Regan and other officials said.

Sen. Tom Carper, chairman of the Senate Environment and Public Works Committee, said he was pleased the administration was moving forward with the methane fee as directed by Congress.

“We know methane is over 80 times more potent than carbon dioxide at trapping heat in our atmosphere in the short term,'' said Carper, D-Del. He said the program "will incentivize producers to cut wasteful and excessive methane emissions during oil and gas production.”

New Jersey Rep. Frank Pallone, the top Democrat on the House Energy and Commerce Committee, said oil and gas companies have long calculated that it's cheaper to waste methane through flaring and other techniques than to make necessary upgrades to prevent leaks.

“Wasted methane never makes its way to consumers, but they are nevertheless stuck with the bill,” Pallone said. The proposed methane fee “will ensure consumers no longer pay for wasted energy or the harm its emissions can cause.''

Republicans call the methane fee a tax that could raise the price of natural gas. “This proposal means increased costs for employers and higher energy bills for millions of Americans,” said Sen. Shelley Moore Capito, R-West Virginia.

The American Petroleum Institute, the oil and gas industry's largest lobbying group, slammed the proposal Friday and called for Congress to repeal it.

“As the world looks to U.S. energy producers to provide stability in an increasingly unstable world, this punitive tax increase is a serious misstep that undermines America’s energy advantage,'' said Dustin Meyer, API's senior vice president of policy, economics and regulatory affairs.

While the group supports “smart” federal methane regulation, the EPA proposal “creates an incoherent, confusing regulatory regime that will only stifle innovation and undermine our ability to meet rising energy demand,'' Meyer said. “We look forward to working with Congress to repeal the IRA’s misguided new tax on American energy.”

Fred Krupp, president of the Environmental Defense Fund, called the proposed fee "common sense,'' adding that oil and gas companies should be held accountable for methane pollution, a primary source of global warming.

In a related development, EPA said it is working with industry and others to improve how methane emissions are reported, citing numerous studies showing that and oil and gas companies have significantly underreported their methane emissions to the EPA under the agency's Greenhouse Gas Reporting Program.

The climate law, formally known as the Inflation Reduction Act, established a waste-emissions charge for methane from oil and gas facilities that report emissions of more than 25,000 metric tons of carbon dioxide equivalent per year to the EPA. The proposal announced Friday sets out details of how the fee will be implemented, including how exemptions will be applied.

The agency said it expects that over time, fewer oil and gas sites will be charged as they reduce their emissions in compliance with the rule.

Houston clean energy pioneer earns prestigious Welch Foundation award

Awards Season

A Rice University professor has earned a prestigious award from the Houston-based Welch Foundation, which supports chemistry research.

The foundation gave its 2025 Norman Hackerman Award in Chemical Research to Haotian Wang for his “exceptionally creative” research involving carbon dioxide electrochemistry. His research enables CO2 to be converted into valuable chemicals and fuels.

The award included $100,000 and a bronze sculpture.

“Dr. Wang’s extensive body of work and rigorous pursuit of efficient electrochemical solutions to practical problems set him apart as a top innovator among early-career researchers,” Catherine Murphy, chairwoman of the foundation’s Scientific Advisory Board, said in a news release.

Wang is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice. The department’s Wang Group develops nanomaterials and electrolyzers for energy and environmental uses, such as energy storage, chemical and fuel generation, green synthesis and water treatment.

Wang also is co-founder of Solidec, a Houston startup that aims to turn his innovations into low-carbon fuels, carbon-negative hydrogen and carbon-neutral peroxide. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions.

Solidec has been selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

“Dr. Wang’s use of electrochemistry to close the carbon cycle and develop renewable sources of industrial chemicals directly intersects with the Welch Foundation mission of advancing chemistry while improving life,” Fred Brazelton, chairman and director of the Welch Foundation, said in the release.

Ramamoorthy Ramesh, executive vice president for research at Rice University, added: “We are proud to (Dr. Wang) at Rice. He’s using chemical engineering to solve a big problem for humanity, everything that the Welch Foundation stands for.”

Last year, the Hackerman Award went to Baylor College of Medicine's Livia Schiavinato Eberlin, who's known for her groundbreaking work in the application of mass spectrometry technologies, which are changing how physicians treat cancer and analyze tissues. Read more here.

Houston venture firm invests in Virginia fusion power plant company in collaboration with TAMU

fusion funding

Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.

Solar farms are booming and putting thousands of hungry sheep to work

Solar Power

On rural Texas farmland, beneath hundreds of rows of solar panels, a troop of stocky sheep rummage through pasture, casually bumping into one another as they remain committed to a single task: chewing grass.

The booming solar industry has found an unlikely mascot in sheep as large-scale solar farms crop up across the U.S. and in the plain fields of Texas. In Milam County, outside Austin, SB Energy operates the fifth-largest solar project in the country, capable of generating 900 megawatts of power across 4,000 acres.

How do they manage all that grass? With the help of about 3,000 sheep, which are better suited than lawnmowers to fit between small crevices and chew away rain or shine.

The proliferation of sheep on solar farms is part of a broader trend — solar grazing — that has exploded alongside the solar industry.

Agrivoltaics, a method using land for both solar energy production and agriculture, is on the rise with more than 60 solar grazing projects in the U.S., according to the National Renewable Energy Laboratory. The American Solar Grazing Association says 27 states engage in the practice.

"The industry tends to rely on gas-powered mowers, which kind of contradicts the purpose of renewables," SB Energy asset manager James Hawkins said.

A sunny opportunity
Putting the animals to work on solar fields also provides some help to the sheep and wool market, which has struggled in recent years. The inventory of sheep and lamb in Texas fell to 655,000 in January 2024, a 4% drop from the previous year, according to the most recent figures from the U.S. Department of Agriculture.

Because solar fields use sunny, flat land that is often ideal for livestock grazing, the power plants have been used in coordination with farmers rather than against them.

Sheepherder JR Howard accidentally found himself in the middle of Texas' burgeoning clean energy transition. In 2021, he and his family began contracting with solar farms — sites with hundreds of thousands of solar modules — to use his sheep to eat the grass.

What was once a small business has turned into a full-scale operation with more than 8,000 sheep and 26 employees.

"Just the growth has been kind of crazy for us," said Howard, who named his company Texas Solar Sheep. "It's been great for me and my family."

Following the herd
Some agriculture experts say Howard's success reflects how solar farms have become a boon for some ranchers.

Reid Redden, a sheep farmer and solar vegetation manager in San Angelo, Texas, said a successful sheep business requires agricultural land that has become increasingly scarce.

"Solar grazing is probably the biggest opportunity that the sheep industry had in the United States in several generations," Redden said.

The response to solar grazing has been overwhelmingly positive in rural communities near South Texas solar farms where Redden raises sheep for sites to use, he said.

"I think it softens the blow of the big shock and awe of a big solar farm coming in," Redden said.

Fielding more research
Agrivoltaics itself isn't new. Solar farms are land-intensive and require a lot of space that could be used for food production. Agrivoltaics compensates by allowing the two to coexist, whether growing food or caring for livestock.

There is a lot still unknown about the full effects of solar grazing, said Nuria Gomez-Casanovas, an assistant professor in regenerative system ecology at Texas A&M University.

Not enough studies have been done to know the long-term environmental impacts, such as how viable the soil will be for future agriculture, although Gomez-Casanovas suspects solar grazing may improve sheep productivity because the panels provide shade and can be more cost-efficient than mowing.

"We really have more questions than answers," Gomez-Casanovas said. "There are studies that show that the land productivity is not higher versus solar alone or agriculture alone, so it's context-dependent."

As one of Texas' largest solar sheep operators, Howard has more clients than he can handle. He expects to add about 20 more employees by the end of this year, which would nearly double his current workforce. As for the sheep, he has enough already.
