Houston-based Merichem Technologies has announced successful results from the field trial of its new hydrogen sulfide (H2S) removal technology in the Permian Basin.

The technology, known as ECOTREAT, removed more than 99 percent of hydrogen sulfide gas from natural gas streams, or “sour gas,” without producing solid waste during the month-long trial. It also showed sustained performance even when operating above the unit’s design capacity, according to a news release.

“The industry is continually seeking to reduce both the price and complexity of removing hydrogen sulfide from gas production, especially since oil production has shifted to increasingly sour sources, higher gas ratios, and higher water ratios,” Jeff Gomach, SVP, Merichem Technologies, said in a news release. “ECOTREAT met all its field trial objectives and provides a highly effective method for removing hydrogen sulfide to prevent equipment corrosion, ensure worker safety, meet environmental regulations, and maintain product quality for transport.

H2S found in natural gas can turn the gas toxic or hazardous and lead to corrosion in pipelines and processing equipment. However, standard H2S removal technologies create high levels of solid waste. ECOTREAT resolves many of those issues by using an aqueous-phase proprietary catalytic process that converts H2S into dissolved thiosulfate.

Next, Merichem says it plans to move the technology out of the pilot stage to full-scale commercialization.

Merichem, an 80-plus-year-old company, initially launched as a soap and industrial cleaning company. It eventually transitioned to focus on energy technology.

In 2024, Black Bay Energy acquired a portion of Merichem Process Technologies and Merichem Catalyst Products, which would become Merichem Technologies.

How Corrolytics is tackling industrial corrosion and cutting emissions

now streaming

Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.

In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.

From Lab Insight to Industrial Breakthrough

Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.

That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.

“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”

Why Corrosion Matters in Houston's Energy Transition

Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.

This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.

Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”

A Scientist Steps Into the CEO Role

Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.

Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.

Why Houston

Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.

What's Next

Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.

A new generation of technology is making it faster, safer, and more cost-effective to identify CUI. Courtesy photo

The case for smarter CUI inspections in the energy sector

Guest Column

Corrosion under insulation (CUI) accounts for roughly 60% of pipeline leaks in the U.S. oil and gas sector. Yet many operators still rely on outdated inspection methods that are slow, risky, and economically unsustainable.

This year, widespread budget cuts and layoffs across the sector are forcing refineries to do more with less. Efficiency is no longer a goal; it’s a mandate. The challenge: how to maintain safety and reliability without overextending resources?

Fortunately, a new generation of technologies is gaining traction in the oil and gas industry, offering operators faster, safer, and more cost-effective ways to identify and mitigate CUI.

Hidden cost of corrosion

Corrosion is a pervasive threat, with CUI posing the greatest risk to refinery operations. Insulation conceals damage until it becomes severe, making detection difficult and ultimately leading to failure. NACE International estimates the annual cost of corrosion in the U.S. at $276 billion.

Compounding the issue is aging infrastructure: roughly half of the nation’s 2.6 million miles of pipeline are over 50 years old. Aging infrastructure increases the urgency and the cost of inspections.

So, the question is: Are we at a breaking point or an inflection point? The answer depends largely on how quickly the industry can move beyond inspection methods that no longer match today's operational or economic realities.

Legacy methods such as insulation stripping, scaffolding, and manual NDT are slow, hazardous, and offer incomplete coverage. With maintenance budgets tightening, these methods are no longer viable.

Why traditional inspection falls short

Without question, what worked 50 years ago no longer works today. Traditional inspection methods are slow, siloed, and dangerously incomplete.

Insulation removal:

Disruptive and expensive.
Labor-intensive and time-consuming, with a high risk of process upsets and insulation damage.
Limited coverage. Often targets a small percentage of piping, leaving large areas unchecked.
Health risks: Exposes workers to hazardous materials such as asbestos or fiberglass.

Rope access and scaffolding:

Safety hazards. Falls from height remain a leading cause of injury.
Restricted time and access. Weather, fatigue, and complex layouts limit coverage and effectiveness.
High coordination costs. Multiple contractors, complex scheduling, and oversight, which require continuous monitoring, documentation, and compliance assurance across vendors and protocols drive up costs.

Spot checks:

Low detection probability. Random sampling often fails to detect localized corrosion.
Data gaps. Paper records and inconsistent methods hinder lifecycle asset planning.
Reactive, not proactive: Problems are often discovered late after damage has already occurred.

A smarter way forward

While traditional NDT methods for CUI like Pulsed Eddy Current (PEC) and Real-Time Radiography (RTR) remain valuable, the addition of robotic systems, sensors, and AI are transforming CUI inspection.

Robotic systems, sensors, and AI are reshaping how CUI inspections are conducted, reducing reliance on manual labor and enabling broader, data-rich asset visibility for better planning and decision-making.

ARIX Technologies, for example, introduced pipe-climbing robotic systems capable of full-coverage inspections of insulated pipes without the need for insulation removal. Venus, ARIX’s pipe-climbing robot, delivers full 360° CUI data across both vertical and horizontal pipe circuits — without magnets, scaffolding, or insulation removal. It captures high-resolution visuals and Pulsed Eddy Current (PEC) data simultaneously, allowing operators to review inspection video and analyze corrosion insights in one integrated workflow. This streamlines data collection, speeds up analysis, and keeps personnel out of hazardous zones — making inspections faster, safer, and far more actionable.

These integrated technology platforms are driving measurable gains:

Autonomous grid scanning: Delivers structured, repeatable coverage across pipe surfaces for greater inspection consistency.
Integrated inspection portal: Combines PEC, RTR, and video into a unified 3D visualization, streamlining analysis across inspection teams.
Actionable insights: Enables more confident planning and risk forecasting through digital, shareable data—not siloed or static.

Real-world results

Petromax Refining adopted ARIX’s robotic inspection systems to modernize its CUI inspections, and its results were substantial and measurable:

Inspection time dropped from nine months to 39 days.
Costs were cut by 63% compared to traditional methods.
Scaffolding was minimized 99%, reducing hazardous risks and labor demands.
Data accuracy improved, supporting more innovative maintenance planning.

Why the time is now

Energy operators face mounting pressure from all sides: aging infrastructure, constrained budgets, rising safety risks, and growing ESG expectations.

In the U.S., downstream operators are increasingly piloting drone and crawler solutions to automate inspection rounds in refineries, tank farms, and pipelines. Over 92% of oil and gas companies report that they are investing in AI or robotic technologies or have plans to invest soon to modernize operations.

The tools are here. The data is here. Smarter inspection is no longer aspirational — it’s operational. The case has been made. Petromax and others are showing what’s possible. Smarter inspection is no longer a leap but a step forward.

Texas Gov. Abbott broadens crackdown on data centers by halting all permits

data center crackdown

Responding to public outcry, Gov. Greg Abbott has stepped up his campaign against data centers by temporarily halting approval of environmental permits for data center projects.

This and previous moves by Abbott essentially amount to a temporary freeze on the development of new data centers in Texas. His actions come at a time when Texas’ stature as a data center hub has been soaring.

On Monday, Abbott directed the Texas Commission on Environmental Quality to stop issuing permits for data center developments until the Electric Reliability Council of Texas (ERCOT) and Public Utility Commission of Texas complete their review of projects seeking power grid connections.

With regulatory reviews underway and environmental permitting now frozen, state regulators currently cannot approve or deny requests from data center developers, Abbott said.

In a letter to the environmental quality commission’s executive director, Kelly Keel, Abbott said this directive is “consistent with my whole-of-government approach to ensure Texans’ natural resources and way of life are protected.”

Abbott previously ordered the Texas Water Development Board to require data centers to meet reporting requirements for water use. He also told the board to impose penalties for failure to comply with those requirements and to collaborate with ERCOT on its review.

Abbott launched his crackdown on data centers in August by ordering the Public Utility Commission and ERCOT to review data center projects in Texas. The audits will examine all data centers in the queue for interconnections before any more projects can move forward. Interconnections enable data centers to share power, data and computing resources.

In calling for those audits, Abbott cited concerns over data centers’ use of water and electricity, and the centers’ effect on infrastructure expenses and consumers’ utility rates.

“Simply put, Texans must come first,” the governor said.

During next year’s legislation session, Abbott will push for the elimination of state financial incentives for data center projects.

Ed Hirs, an energy fellow ⁠at the University of Houston, told Reuters that Abbott was backtracking on “his earlier pronouncements about data centers leading to lower electricity prices.”

Abbott’s actions come amid growing public backlash over data centers. A recent University of Houston survey found that nearly 63 percent of Houston-area residents opposed construction of a data center within a mile of their home.

Only 8 of 160 utility companies in Texas have filed wildfire response plans

Utility News

Only eight of 160 utility companies that operate in fire-prone areas of Texas have complied with a law that helps mitigate wildfires, lawmakers recently learned. The revelation comes on the heels of a chaotic wildfire season that has continued through the summer.

Lawmakers learned about the slow progress last week during a House State Affairs committee hearing, led by Rep. Ken King, who led the charge on the new law last year. The law under House Bill 145 requires utility companies to file wildfire mitigation plans to the Public Utility Commission.

The plans must include emergency protocols in the case of a wildfire, utility operating plans during high-risk weather conditions, management of grass, shrubs and other vegetation in areas that are at risk of wildfires, inspection of poles and other electric equipment and identified areas of wildfire risks within a utility’s service territory.

King, a Republican from Canadian where much of the wildfire damage occurred during the Panhandle wildfires, pressed utility companies on the lack of compliance.

“I’m very, very disappointed with the industry,” King said. “I think it’s imperative for anybody that has not filed that report to realize January is coming. You will file that wildfire mitigation plan, and if you’re dragging your feet, there’s no excuse good enough for me.”

Last year, King filed a slew of bills in response to the devastating Smokehouse Creek wildfires in the Texas Panhandle and parts of Oklahoma in 2024. It was the largest wildfire in Texas history, started when a decayed power pole owned by Xcel Energy snapped and landed in dry grass.

It was one of a spate of fires, the majority of which were linked to electrical ignitions.

This year alone has been a very active wildfire season. Nim Kidd, chief for the Texas Division of Emergency Management, said the state has helped local governments respond to more than 1,200 fires since the start of the year. The Ross Fire, which burned for more than three weeks in North Texas, was finally contained by firefighters last week. It’s now the second largest wildfire in the region’s history.

Two wildfires have broken out on Craig Cowden’s Panhandle ranch this year, both ignited by electrical equipment used by oil and gas companies. Cowden extinguished them, before they could spread beyond 5 acres — a fraction of the 20,000 acres he lost to wildfires in 2024.

Cowden was one of many ranchers who worked with lawmakers last year to address the problem. Over the years, several fires have started on Cowden’s land, most of which were the result of faulty or damaged electrical equipment.

“It’s kind of discouraging that there hasn’t been more proactively submitting their wildfire plan,” Cowden said.

Slow progress

There has been progress since the bill was filed. According to King, six fires have been linked to electrical issues this year, a significant decrease from 80 in 2024.

Connie Corona, director at the PUC, explained the lag in filings to lawmakers, stating that on top of the eight who have submitted, four more have given the PUC a date for when they intend to file their plans. Corona said another 135 have indicated to the PUC they are in the process of preparing their plan. This leaves 13 who have not communicated their plans to the PUC.

“We’ve asked for a heads-up notice of when the utility plans to file, and try to ensure that meets with the resources we have available,” Corona told lawmakers.

Corona said PUC staff had created a model wildfire mitigation plan that utility companies can use as a template. The model is intended to support smaller utility companies that lack sufficient resources to make their own plan. King asked Corona for a list of entities who complied with the requirement.

“When eight out of 160 have complied, and we’re sitting here in September, that doesn’t sound like a very good response to me,” King said.

A looming deadline

Brad Baldridge, interim president of Southwestern Public Service Company, which operates as Xcel Energy, told lawmakers what his company is doing to mitigate wildfires. The company was heavily criticized in the wake of the fires and has since deployed 97 wildfire detection cameras across its service territory. The cameras use AI to detect smoke and provide that information in real-time to utility personnel, local fire responders and emergency managers. It also uses Public Safety Power Shutoffs to turn off power in certain areas during critical wildfire conditions to prevent an electrical start. Baldridge said since 2024, the company has had to shut off power five times.

When King asked if the company had submitted its wildfire mitigation plans, Baldridge said it was submitted last month. It would have been submitted earlier, he said, but there was “tremendous” vegetation that grew from rain earlier in the year.

“All of our experts were focusing on wildfire mitigation,” Baldridge said. “Which delayed us a little bit in our filing.”

Mark Bell, CEO for the Association of Electric Companies of Texas, said they are using remote cameras and sensors to detect wildfires and are taking a more aggressive approach to manage vegetation. They also use power shutoffs in extreme conditions to minimize the risk. Bell testified that their utility companies were on track to file their wildfire mitigation plans.

“I think all the plans are going to be filed by the end of the year,” Bell said.

King reminded Bell that it’s September, and many haven’t filed yet.

“That’d be 148 (plans) approved before January,” King said.

Bell assured King that five of them have filed their plans and one is scheduled to file in October.

Corona, with the PUC, said there are also pole and maintenance plans due in January that will detail a complete inventory of those assets owned by utilities. King said the plan is to have the companies list everything they own in Texas, where it is and how old it is. However, he said they aren’t being compliant and lawmakers will see what happens in January.

Cowden, the rancher in the Panhandle, told the Tribune that while it’s not technically fire season anymore, there are still small fires that ignite around the area.

Cowden sees the amount of work being done by Xcel Energy to upgrade their electrical poles and infrastructure in the area. He said it’s different than before the wildfires in 2024. He thinks the fires got their attention.

“You can tell they’re making a conscious effort to try to upgrade their infrastructure,” Cowden said.

Houston-based ‘grid in a box’ provider Branch Energy raises $33M

fresh funding

Houston-based startup Branch Energy, which offers a self-contained “grid in a box,” has collected $33 million in a Series B round.

Piva Capital and Clean Energy Ventures led the round, according to a news release. Active Impact Investments, Whitecap Venture Partners, Prelude Ventures, Zero Infinity Partners and Inovia Capital also contributed to the round.

In 2024, Branch raised $10.8 million in an oversubscribed Series A round.

Branch’s business model

Branch, which launched in 2021, says its proprietary Arc “grid in a box” contains everything needed to store and supply electricity. A container about the size of a parking space holds an industrial-grade battery, grid connection equipment, cooling capabilities, autonomous controls and cloud-based management software.

The startup installs Arc systems at warehouses, hotels, factories, stores and other commercial properties. Each system arrives on a flatbed truck and can be online within two days, Branch says.

Under Branch’s business model, a property owner avoids upfront payment for an Arc system.

Aside from equipping a host business with an Arc system, Branch serves as the business’ power provider. The startup says it guarantees savings on the host’s energy bills and delivers backup power during outages.

Branch generates revenue by sending the battery’s stored power to the grid or to customers like hyperscale data centers. It also benefits by shifting energy from low-cost periods at night to high-cost periods during daily power peaks.

The startup handles permitting, installation, insurance and operations for each Arc system. The host provides a parking-lot-sized plot of land for the system.

Alex Ince-Cushman, co-founder and CEO of Branch, says the startup’s “grid in a box” can quickly meet the substantial power requirements of hyperscale data centers.

“We can do it on the timeline of a delivery, not a construction project. Our customers don’t lift a finger, don’t pay a dime and get guaranteed savings,” Ince-Cushman said in the release.

Entering the Illinois market

Branch already operates in Texas and is entering the Illinois market.

PJM, which operates Illinois’ power grid, recently paved the way for major energy users like data centers to connect to the grid sooner when they rely on their own electricity generation. PJM’s territory covers roughly 1.2 million commercial buildings and represents 20 percent of U.S. power demand, according to Branch.

“Grids around the country need the distributed capacity that [the Arc] system can supply, especially in states with fast-growing power demand like Texas and Illinois,” Lee Larson, principal at Piva Capital added in the release.

To keep up with that demand, Branch plans to build tens of thousands of Arc systems in the U.S.

A multibillion-dollar company in the making?

Daniel Goldman, co-founder and managing partner of Clean Energy Ventures, said Branch holds the potential to become a multibillion-dollar competitor in the emerging market for distributed power.

“With utility-scale generation and storage challenged by interconnect and siting constraints, behind-the-meter commercial, and industrial storage sites have become the ultimate market opportunity with ease of interconnect, ability to combine distributed AI data centers, and identifiable savings in rapidly growing markets,” Goldman said.
