Methane emissions are rising—about 25 percent in the past 20 years, and still going up— but they are difficult to measure and track. What can be done? Photo via Canva

Here’s the bad news. In 2019, methane (CH4) accounted for about 10 percent of all U.S. greenhouse gas emissions from human activities, such as those related to natural gas extraction and livestock farming. Methane doesn’t last as long in the atmosphere as carbon dioxide, but is more efficient at trapping radiation; over a 100-year period, the comparative impact of CH4 is 25 times greater than CO2. To put it another way, one metric ton of methane equals 84 metric tons of carbon dioxide (see chart). Finally, while methane emissions are rising—about 25 percent in the past 20 years, and still going up—they are difficult to measure and track.

And here’s the good news. Five industries—agriculture, oil and gas, coal mining, solid waste management, and wastewater—account for almost all of human-made methane emissions. There are practical things these industries can do, right now, at reasonable cost and using existing technologies, that could cut emissions by almost half (46 percent) in 2050. That said, it will be easier for some industries than for others. Take agriculture. Most of its emissions come from cows and sheep, which produce methane during digestion; in fact, animals account for more carbon dioxide equivalent (CO₂e) emissions than every country except China, according to a recent McKinsey report. Dealing with billions of animals, dispersed on farms small and large all over the world is, to put it mildly, complicated. Certain kinds of feed additives, for example, can reduce the formation of methane, cow by cow—but is expensive ($50 per tCO₂e and up). This add costs to farmers, without any economic benefits to them, and makes food more expensive. That’s a tough sell.

On the other hand, the energy industry accounts for 20 to 25 percent of methane emissions; its operations are fairly consolidated, and there are significant resources and expertise at hand. Plus, in many cases, there are genuine economic opportunities. For example, plugging methane leaks means less gas gets lost. Large volumes of methane emissions that are now treated as a waste could be recovered and sold as natural gas—something that is not always economic to do, but could be as gas prices rise or conditions change. According to the International Energy Agency (IEA), the industry flares approximately 90 Mt of methane per year, losing $12 billion to $19 billion in value. Over time, too, normal maintenance and upgrading strategies can also reduce emissions, for example, by replacing pumps with instrument air systems. There are many different ways to prevent losses in upstream production, including leak detection and repair, equipment electrification, and vapor recovery units.

In the short term, meaning over the next decade, the IEA says that these and other changes could reduce emissions 40 percent (at 2019 gas prices), while more than paying for themselves. In effect, there is low-hanging fruit out there. The full potential, according to McKinsey, is 75 percent fewer emissions by 2050, but to get there, things get more expensive, somewhere in the range of $20 per tCO₂e.

Naturally, oil and gas players are not eager to embrace added costs, and these will eventually be passed on to consumers. But the industry is looking at a future that is carbon-constrained in one way or another, either through a price on carbon, or regulation, or both. It might well be that addressing methane emissions provides a way to decarbonize its operations at reasonable cost. And while there is little brand equity to natural gas at the moment—no one shops for it by name—it is possible that in decades to come, companies that can show they are producing low- or zero-carbon gas might be able to command a price premium.

Much of the oil and gas industry doesn’t disagree with this analysis. The International Group of Liquefied Natural Gas Importers, a trade group, has made the case that “abating greenhouse gas emissions (from wellhead to terminal outlet), in particular fugitive methane emissions,” is important. On the oil side, the American Petroleum Institute, as part of its climate action plan, has called for the development of methane detection technologies, and reducing flaring to zero: “We support cost-effective policies and direct regulation that achieve methane emission reductions from new and existing sources across the supply chain.” And the Oil and Gas Climate Initiative, whose companies account for almost 30 percent of global production, are also on board, calling the reduction of methane emissions to near zero “a top priority.” Back in 2017, the Houston Chronicle, the home paper of the Texas oil and gas industry, argued for better practices: “If Texas wants the world to buy our LNG exports, a sign of environmental good faith would go a long way.” And in fact there has been progress: the OGCI estimates that methane emissions are have declined 33 percent from 2017-20.

On the whole, then, this looks like one area of climate policy where there is broad consensus. Methane matters. According to one science paper, dealing with it “could slow the global-mean rate of near-term decadal warming by around 30 percent.” Just the oil-and-gas industry’s share, then, could make a measurable difference. I am not saying getting methane emissions way down will be easy, but the industry knows what to do and how to do it. It is in its interest, and that of the planet, to do so.

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.

CenterPoint launches $65B capital improvement plan

grid growth

To support rising demand for power, Houston-based utility company CenterPoint Energy has launched a $65 billion, 10-year capital improvement plan.

CenterPoint said that in its four-state service territory — Texas, Indiana, Minnesota and Ohio — the money will go toward building and maintaining a “resilient” electric grid and a safe natural gas system.

In the Houston area, CenterPoint forecasts peak demand for electricity will increase nearly 50 percent, to almost 31 gigawatts, by 2031 and peak demand will climb to almost 42 gigawatts by the middle of the next decade. CenterPoint provides energy to nearly 2.8 million customers in the Houston area.

In addition to the $65 billion capital improvement budget, which is almost 40 percent higher than the 2021 budget, CenterPoint has identified more than $10 billion in investment opportunities that could further improve electric and natural gas service.

“Every investment we make at CenterPoint is in service of our approximately seven million metered customers we have the privilege to serve,” CenterPoint president and CEO Jason Wells said in a news release.

“With our customer-driven yet conservative approach to growth, we continue to see significant potential for even more investment for the benefit of our customers that is not yet reflected in our new plan,” he added.

UH projects propose innovative reuse of wind turbines and more on Gulf Coast

Forward-thinking

Two University of Houston science projects have been selected as finalists for the Gulf Futures Challenge, which will award a total of $50 million to develop ideas that help benefit the Gulf Coast.

Sponsored by the National Academies of Science, Engineering and Medicine’s Gulf Coast Research Program and Lever for Change, the competition is designed to spark innovation around problems in the Gulf Coast, such as rising sea levels, pollution, energy security, and community resiliency. The two UH projects beat out 162 entries from organizations based in Alabama, Florida, Louisiana, Mississippi, and Texas.

“Being named a finalist for this highly competitive grant underscores the University of Houston’s role as a leading research institution committed to addressing the most pressing challenges facing our region,” said Claudia Neuhauser, vice president for research at UH.

“This opportunity affirms the strength of our faculty and researchers and highlights UH’s capacity to deliver innovative solutions that will ensure the long-term stability and resilience of the Gulf Coast.”

One project, spearheaded by the UH Repurposing Offshore Infrastructure for Continued Energy (ROICE) program, is studying ways to use decommissioned oil rig platforms in the Gulf of Mexico as both clean energy hydrogen power generators as well a marine habitats. There are currently thousands of such platforms in the Gulf.

The other project involves the innovative recycling of wind turbines into seawall and coastal habitats. Broken and abandoned wind turbine blades have traditionally been thought to be non-recyclable and end up taking up incredible space in landfills. Headed by a partnership between UH, Tulane University, the University of Texas Health Science Center at Houston, the city of Galveston and other organizations, this initiative could vastly reduce the waste associated with wind farm technology.

"Coastal communities face escalating threats from climate change — land erosion, structural corrosion, property damage and negative health impacts,” said Gangbing Song, Moores Professor of Mechanical and Aerospace Engineering at UH and the lead investigator for both projects.

“Leveraging the durability and anti-corrosive properties of these of decommissioned wind turbine blades, we will build coastal structures, improve green spaces and advance the resilience and health of Gulf Coast communities through integrated research, education and outreach.”

The two projects have received a development grant of $300,000 as a prize for making it to the finals. When the winner are announced in early 2026, two of the projects will net $20 million each to bring their vision to life, with the rest earning a consolation prize of $875,000, in additional project support.

In the event that UH doesn't grab the grand prize, the school's scientific innovation will earn a guaranteed $1.75 million for the betterment of the Gulf Coast.

ERCOT steps up grid innovation efforts to support growing power demand

grid boost

As AI data centers gobble up more electricity, the Electric Reliability Council of Texas (ERCOT) — whose grid supplies power to 90 percent of Texas — has launched an initiative to help meet challenges presented by an increasingly strained power grid.

ERCOT, based in the Austin suburb of Taylor, said its new Grid Research, Innovation, and Transformation (GRIT) initiative will tackle research and prototyping of emerging technology and concepts to “deeply understand the implications of rapid grid and technology evolution, positioning ERCOT to lead in the future energy landscape.”

“As the ERCOT grid continues to rapidly evolve, we are seeing greater interest from industry and academia to collaborate on new tools and innovative technologies to advance the reliability needs of tomorrow’s energy systems,” ERCOT President and CEO Pablo Vegas said in a news release. “These efforts will provide an opportunity to share ideas and bring new innovations forward, as we work together to lead the evolution and expansion of the electric power grid.”

In conjunction with the GRIT initiative, ERCOT launched the Research and Innovation Partnership Engagement (RIPE) program. The program enables partners to work with ERCOT on developing technology aimed at resolving grid challenges.

To capitalize on ideas for grid improvements, the organization will host its third annual ERCOT Innovation Summit on March 31 in Round Rock. The summit “brings together thought leaders across the energy research and innovation ecosystem to explore solutions that use innovation to impact grid transformation,” ERCOT said.

“As the depth of information and industry collaboration evolves, we will continue to enhance the GRIT webpages to create a dynamic and valuable resource for the broader industry to continue fostering strong collaboration and innovation with our stakeholders,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation.

ERCOT’s GRIT initiative comes at a time when the U.S. is girding for heightened demand for power, due in large part to the rise of data centers catering to the AI boom.

A study released in 2024 by the Electric Power Research Institute (EPRI) predicted electricity for data centers could represent as much as 9.1 percent of total power usage in the U.S. by 2030. According to EPRI, the share of Texas electricity consumed by data centers could climb from 4.6 percent in 2023 to almost 11 percent by 2030.

A report issued in 2024 by the federal government’s Lawrence Berkeley National Laboratory envisions an even faster increase in data-center power usage. The report projected data centers will consume as much as 12 percent of U.S. electricity by 2028, up from 4.4 percent in 2023.

In 2023, the EPRI study estimated, 80 percent of the U.S. electrical load for data centers was concentrated in two states, led by Virginia and Texas. The University of Texas at Austin’s Center for Media Engagement reported in July that Texas is home to 350 data centers, second only to Virginia.

“The U.S. electricity sector is working hard to meet the growing demands of data centers, transportation electrification, crypto-mining, and industrial onshoring, while balancing decarbonization efforts,” David Porter, EPRI’s vice president of electrification and sustainable energy strategy, said. “The data center boom requires closer collaboration between large data center owners and developers, utilities, government, and other stakeholders to ensure that we can power the needs of AI while maintaining reliable, affordable power to all customers.”
