4 layoff alternatives energy businesses should consider in a downturn, according to this Houston expert

Here's what you should consider if you need to make cuts to your business — now or in the future. Photo via Getty Images

Preparing for a potential economic downturn can be unsettling for employers and employees. As payroll is typically one of the largest expenditures for a business, no matter its size, layoffs seem like the quickest fix. While this may offer short-term relief, they can severely impact operations and workplace culture.

When staff is reduced, culture can suffer. Employee morale can decrease and distrust may build, especially if layoffs are not communicated properly. This can lead to the remaining employees feeling anxious about their own future with the organization and spur them to look for employment elsewhere, which can affect an organization’s overall productivity and day-to-day operations.

Business owners should get creative and consider the impact and the many alternatives before resorting to workforce reductions. Continue reading the article by Karen Leal of Insperity.

Finding a Balance: Growing renewable energy vs. grid resilience in Texas

Balancing renewable energy growth and grid resilience requires a multifaceted approach. Photo via Getty Images

The global energy sector is on an exhilarating trajectory, teeming with promising technologies and unprecedented opportunities for a sustainable future. Yet, we find ourselves grappling with the challenges of reliability and affordability. As both a researcher in the field of power electronics and a consumer with bills to pay, I find myself experiencing mixed feelings.

As a researcher, I am thrilled by the progress we have achieved, particularly in energy conversion. The exponential growth of renewable energy technologies in Texas and beyond, including wind turbines and solar PV systems, is cause for celebration. These innovations, coupled with supportive policies, have facilitated widespread deployment and the potential to significantly reduce greenhouse gas emissions, combat climate change, and create a brighter future for our children.

While renewable energy resources can play a crucial role in maintaining the supply-demand balance of the grid, as they did by performing very well during the recent 2023 Texas heat wave, their intermittent and unpredictable nature can also pose a significant challenge to the power system. Unlike traditional power plants that operate continuously, wind turbines and solar PV systems rely on weather conditions for optimal performance. Fluctuations in wind speed, cloud cover, and sunlight intensity can lead to imbalances between energy supply and demand. This imbalance will worsen as the anticipated influx of electric vehicles and their charging needs come into play. Continue reading the article by Harish Krishnamoorthy of the University of Houston.

Founder on ringing the NYSE bell and shining a spotlight on the future of energy in Houston

As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero. The people who power the energy industry will do the hard work. We’ve already begun. And we’re unafraid of the long journey ahead — something more than 40 of us exemplified that weekend by running a marathon.

The trip to New York City days ago was an exhilarating whirlwind. But it was also something much more: A chance to show the markets, the nation, and the world that Houston is leading the energy transition. (It didn’t hurt that we popped up on Good Morning America.)

From the beginning, the idea behind this pair of events — ringing the bell at the New York Stock Exchange and running the TCS New York City Marathon — was aimed at sending crucial messages. That recognizing climate change and building solutions is an obligation and an opportunity. That the energy industry understands this. That investors have good reason to support climate tech, one of the most exciting and fastest growing sectors. And, last but not least, that people’s perceptions of Houston as being all about oil and gas are simply wrong. Continue reading the article by Katie Mehnert of Ally Energy.

Houston faces critical inflection point amid energy transition, says expert

The question the Houston business community must be able to answer today is “Are we going to be ready for 2035?” Photo via Getty Images

In 1914, Winston Churchill faced a difficult decision. Over two decades before his first term as Prime Minister during World War 2, he oversaw the entire Royal Navy as First Lord of the Admiralty. Shipbuilding technology was rapidly evolving in that era and one of the key questions was whether to use coal or oil as fuel for the large ships in the fleet. Coal was the more proven technology at that point and the British had a strong supply chain across the Empire. Oil was lighter and easier to operate, but the worldwide supply and infrastructure were still limited.

Ultimately Churchill was persuaded by Admiral Jacky Fisher and others to convert the entire fleet to oil. To resolve the supply chain issue, the British government bought a majority stake in Anglo-Persian Oil Company, which became BP. The Royal Navy was possibly the largest consumer of fuel worldwide at the time, so this decision had a major effect on the energy transition in that era. Within 30 years, steam engines were no longer used for transportation in most of the world.

In that same decade, Houston emerged as a leading energy hub in the United States: Humble Oil was founded, the Houston Ship Channel was dredged, and the Baytown Refinery was constructed. World War I in Europe, and the mass adoption of cars in the US spurred a major increase in demand for oil. Oil went on to dominate the global energy market, providing cheap and reliable transportation, industrial production, and materials. Houston grew and prospered along with it to become the 5th largest metro area in the country today. Continue reading the article by Drew Philpot of Blended Power.

Houston can help unlock the key to a viable energy transition

The future of energy holds monumental and diverse expectations. Houston’s long history as the hub for oil and gas development – combined with its growing and important role in development of renewables, carbon capture, and other energy innovation – makes it a critical meeting point for discussions on strategy, investment, and stakeholder engagement in the energy transition.

In our research last fall, we detailed how the oil and gas industry was embracing capital discipline and prioritizing shareholder returns. The industry generated record cash flows and offered a combined dividend and share buyback yield of 8 percent in 2022—the highest among all industries. The industry’s commitment to maintaining capital discipline and investing in viable low-carbon projects has only strengthened in 2023.

In fact, according to our most recent research, the global upstream oil and gas industry is estimated to generate between $2.5 trillion to $4.6 trillion in free cash flow between 2023 and 2030. With capital availability not posing a significant constraint, boardrooms of oil and gas companies are engaged in discussions regarding capital allocation between hydrocarbons and low-carbon solutions, while striving to achieve desired rates of return and meet stakeholder expectations for dividend payouts.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.

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.

Scientists warn greenhouse gas accumulation is accelerating and more extreme weather will come

Climate Report

Humans are on track to release so much greenhouse gas in less than three years that a key threshold for limiting global warming will be nearly unavoidable, according to a study released June 19.

The report predicts that society will have emitted enough carbon dioxide by early 2028 that crossing an important long-term temperature boundary will be more likely than not. The scientists calculate that by that point there will be enough of the heat-trapping gas in the atmosphere to create a 50-50 chance or greater that the world will be locked in to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of long-term warming since preindustrial times. That level of gas accumulation, which comes from the burning of fuels like gasoline, oil and coal, is sooner than the same group of 60 international scientists calculated in a study last year.

“Things aren’t just getting worse. They’re getting worse faster,” said study co-author Zeke Hausfather of the tech firm Stripe and the climate monitoring group Berkeley Earth. “We’re actively moving in the wrong direction in a critical period of time that we would need to meet our most ambitious climate goals. Some reports, there’s a silver lining. I don’t think there really is one in this one.”

That 1.5 goal, first set in the 2015 Paris agreement, has been a cornerstone of international efforts to curb worsening climate change. Scientists say crossing that limit would mean worse heat waves and droughts, bigger storms and sea-level rise that could imperil small island nations. Over the last 150 years, scientists have established a direct correlation between the release of certain levels of carbon dioxide, along with other greenhouse gases like methane, and specific increases in global temperatures.

In Thursday's Indicators of Global Climate Change report, researchers calculated that society can spew only 143 billion more tons (130 billion metric tons) of carbon dioxide before the 1.5 limit becomes technically inevitable. The world is producing 46 billion tons (42 billion metric tons) a year, so that inevitability should hit around February 2028 because the report is measured from the start of this year, the scientists wrote. The world now stands at about 1.24 degrees Celsius (2.23 degrees Fahrenheit) of long-term warming since preindustrial times, the report said.

Earth's energy imbalance

The report, which was published in the journal Earth System Science Data, shows that the rate of human-caused warming per decade has increased to nearly half a degree (0.27 degrees Celsius) per decade, Hausfather said. And the imbalance between the heat Earth absorbs from the sun and the amount it radiates out to space, a key climate change signal, is accelerating, the report said.

“It's quite a depressing picture unfortunately, where if you look across the indicators, we find that records are really being broken everywhere,” said lead author Piers Forster, director of the Priestley Centre for Climate Futures at the University of Leeds in England. “I can't conceive of a situation where we can really avoid passing 1.5 degrees of very long-term temperature change.”

The increase in emissions from fossil-fuel burning is the main driver. But reduced particle pollution, which includes soot and smog, is another factor because those particles had a cooling effect that masked even more warming from appearing, scientists said. Changes in clouds also factor in. That all shows up in Earth’s energy imbalance, which is now 25% higher than it was just a decade or so ago, Forster said.

Earth’s energy imbalance “is the most important measure of the amount of heat being trapped in the system,” Hausfather said.

Earth keeps absorbing more and more heat than it releases. “It is very clearly accelerating. It’s worrisome,” he said.

Crossing the temperature limit

The planet temporarily passed the key 1.5 limit last year. The world hit 1.52 degrees Celsius (2.74 degrees Fahrenheit) of warming since preindustrial times for an entire year in 2024, but the Paris threshold is meant to be measured over a longer period, usually considered 20 years. Still, the globe could reach that long-term threshold in the next few years even if individual years haven't consistently hit that mark, because of how the Earth's carbon cycle works.

That 1.5 is “a clear limit, a political limit for which countries have decided that beyond which the impact of climate change would be unacceptable to their societies,” said study co-author Joeri Rogelj, a climate scientist at Imperial College London.

The mark is so important because once it is crossed, many small island nations could eventually disappear because of sea level rise, and scientific evidence shows that the impacts become particularly extreme beyond that level, especially hurting poor and vulnerable populations, he said. He added that efforts to curb emissions and the impacts of climate change must continue even if the 1.5 degree threshold is exceeded.

Crossing the threshold "means increasingly more frequent and severe climate extremes of the type we are now seeing all too often in the U.S. and around the world — unprecedented heat waves, extreme hot drought, extreme rainfall events, and bigger storms,” said University of Michigan environment school dean Jonathan Overpeck, who wasn't part of the study.

Andrew Dessler, a Texas A&M University climate scientist who wasn't part of the study, said the 1.5 goal was aspirational and not realistic, so people shouldn’t focus on that particular threshold.

“Missing it does not mean the end of the world,” Dessler said in an email, though he agreed that “each tenth of a degree of warming will bring increasingly worse impacts.”
