With a mind for business and a passion for people, one woman leads the legacy her family trailblazed in corporate social responsibility.

Revani “Rani” Puranik, named successor for the CEO of Worldwide Oilfield Machine (“WOM”) and current Chair of the Puranik Foundation, continues the institutions her parents created with the same emphasis on mindfulness, sustainability, and opportunity for all.

In addition to extending the reach of WOM’s 3,000+ employees across 10 countries–and counting–Puranik shapes future leaders and innovators of energy through The Energy Project, a program launched in 2020 by the foundation to support young minds tackling environmental challenges for sustainable development across five sectors: Alternative Power Generation, Sustainable Consumption, Waste Management, Urban Design, and Water Sustainability.

In her upcoming book, Seven Letters to My Daughters, scheduled for release on May 24^th, Puranik shares lessons in love, leadership, and legacy carved out of distinct seven-year periods of her life. And if inspiring the next generation and writing a book weren’t enough, Puranik has her eyes set on building a more holistic charter school in collaboration with Baylor College of Medicine.

With just a moment to spare before she launches a new initiative, Puranik met with EnergyCapitalHTX to discuss what Energy Transition looks like from her perspective.

EnergyCapitalHTX: You’ve had an interesting career, with one foot in something very altruistic, and the other in energy–which has a reputation for being… not so altruistic, let’s say. How did you get here?

Rani Puranik: First, I'll tell you that none of it, none of it, was planned.

The 1st 17 years of my life, I lived in Houston. I went to Lamar high school thinking I was going to be an engineer. But I was on a robust and dedicated journey singing and dancing, too. I was always very active and engaged in my heritage that way.

I went to India after I graduated from high school and stayed in my parents’ vacation home, which was next to a poverty-stricken area. All I thought was, “hey, how can I help?”

And that “how can I help?“ has always turned into larger projects than I ever imagined. Before long, I was running an after-school dance program for 60 kids. But it was more than dance. These girls needed a safe space to express themselves.

EC: How did you end up back in Houston?

RP: Well, life happens. I came to Houston on a one-way ticket with $200 in my pocket. My dad was still living here in Houston, running Worldwide Machine, so I volunteered in his company to keep busy.

Finally, in 2012, I realized I’m never going to be an engineer; I graduated from Rice with an MBA in finance in 2014. And then I just dedicated my entire life to WOM, my two girls, and the Puranik Foundation my mother started when I was in India.

EC: On one hand, you're encouraging innovation around building a sustainable environment with Puranik Foundation. And with WOM, you provide offshore equipment, services, and expertise. Do you see those concepts blending as part of the energy transition?

RP: One of the core principles of WOM is “stay curious.” We have something called the Idea Factory; sometimes we get ideas that are related to sustainability and alternative energies. The people that come up with these solutions and methods are deeply involved from start to finish as part of our research and development team.

We’ve currently got a patent on a frac valve that is so much healthier for the environment. There’s no disposal of grease, there’s much less use of water and chemicals injected because of the way our frac valve operates, and the pressures and temperatures it can sustain and withhold.

We’re also looking at design, revisiting processes and asking, “how can we make this more efficient?” How can we reduce not just the emissions, but the use of oils and liquids and fuels with process improvements and enhancements for the equipment that we're manufacturing?

EC: And for the foundation?

RP: What's important for me is to understand what energy is, why it's needed, and how we can tap into it from all sources.

If younger minds can think of things like some of the students in this year’s cohort of The Energy Project– things like using human movement to not just capture, but transform, energy–we're headed in the right direction.

EC: The energy transition is increasingly branded as a transition in mindset more than anything. Mindfulness is a core tenet of your foundation, is it a part of the nine core principles of WOM you mentioned?

RP: Absolutely. I've been called an empathetic leader because I listen. And I say the first part of listening is receiving. When you receive information, you're empowering yourself with knowledge and information being shared by someone else for you. And then you can offer a direction, a guide, or just a helping hand.

There's definitely a shift going on where people not just want to be heard, but there are leaders and organizations who understand the value and the importance of it. We can't do things on our own.

EC: You emphasize collaboration and human connectivity often, which are vital components of the sustainability economy. Can you elaborate on how your organizations embody these concepts?

RP: I made up the “earn to return” philosophy because I saw it in my own parents and I said, I've been given very valuable resources and I've been given a talent to connect people. And if together, that can create something beautiful to really enhance the abundance of resources and create stable pathways for people in their livelihoods, then that's my purpose and that's what I'm going to do.

And in the process, yeah, we make great sales, great profits. But then the profits have to be returned back to our local communities and our people and our kids so that they end up having stable livelihoods for their future. For me, that was always the driving force, and it still is.

But I'll tell you again, none of it was planned. None.

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.”
