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 24th, 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.

Sustainability-focused philanthropy recognizes student innovations, local leaders

EMPOWERING THE TRANSITION

From the moment of arrival at the Puranik Foundation Lotus Innovation Awards, attendees engaged in an experience that stimulated the senses and excited the mind – a precise reflection of the foundation’s approach to a holistic education for future innovators.

The event, held last week at the Post Oak Hotel in Uptown, honored Houston leaders supporting the next generation of aspiring entrepreneurs and celebrated the dedication of high school students dreaming sustainability solutions into reality.

“[These students] have the potential to reach innovative places that none of us can think of because we are so set in our ways,“ says Bhakti Puranik, executive director of Puranik Foundation, just steps from where the students showcased their prototypes to secure the gala’s Fan Favorite award. “They are open-minded and creative and constantly inspired by the community that surrounds us.”

The Energy Project, launched in 2020 by the foundation, supports young minds tackling environmental challenges for sustainable development across five sectors: alternative power generation, sustainable consumption, waste management, urban design, and water sustainability.

Multiple small student teams from across the country met for design thinking lessons before creating prototypes of their own solutions at TXRX Labs. The foundation’s primary sponsor, Worldwide Oilfield Machine, provided mentors and resources to the 25 students in this year’s cohort alongside Rice University.

For the winning team, Refoam Maine, the application of mushroom mycelium in lieu of plastic for floating buoys came from the optimistic minds of Maggie Blood, Olivia Huard, Tula Bradley Prindiville, and Laura Riordan, students of Camden Hills Regional High School near Rockport, Maine.

A close-knit community, Camden Hills has collectively seen thousands of orphaned buoys pile up against their docks and beaches for years. The team plans to use their Lotus Innovation Award grant of $15,000 to get their floats in the water, and is actively working with boatyards, aquaculture farmers, and others to bring that vision to reality this summer.

Cyrus Golshan, Nathaniel Lemon, and Alexander Kristof took home the Fan Favorite Award for their solution Piezot, which harnesses energy from revolutionary piezoelectric tiles that convert pressure into energy and electricity.

The team studies at the Energy Institute High School in Houston and envisions an energy ecosystem that doesn’t rely so heavily on natural forces, but rather on human movement as a means to generate power. Placement of the tiles in high-traffic areas like airports, schools, and shopping centers could mean an exponential growth in power supply created simply by the many feet that pass through these areas every day.

Bobby Tudor, CEO and founder of Artemis Energy Partners, and recipient of the Sustainability Lotus Award from Puranik Foundation, attributes the success of the program to the convergence of expertise, a collaborative ecosystem, and global connectivity available from Houston as part of the burgeoning Energy Transition industry.

“We are the energy capital of the world because we are the intellectual capital of energy,“ says Tudor. “The knowledge, the engineering, the expertise, sits here in a more concentrated way than it sits anywhere else in the world. It is that intellectual capital that will pave the way for us to continue to be the energy capital of the world a decade from now, two decades from now, and five decades from now.”

Additionally, Paula Harris, senior vice president of the Houston Astros Community Affairs and Executive Director for the Astros Foundation, accepted the Education Lotus Award for her continued commitment to advancing STEM education across underserved communities.

For his positive impact on the mental well-being of students, Bradley H. Smith, Ph.D., Professor of Psychological, Health, and Learning Services at the University of Houston School of Psychology, Puranik Foundation honored him with Mindfulness Lotus Award.

Applications for The Energy Project are due by 1 November each fall. In addition to the team competition, next year’s cohort includes an immersive experience in India for holistic learning and leadership development.

Fervo named to prestigious list of climate tech companies to watch

top honor

Houston-based Fervo Energy has received yet another accolade—MIT Technology Review named the geothermal energy startup to its 2025 list of the 10 global climatetech companies to watch.

Fervo, making its second appearance on the third annual list, harnesses heat from deep below the ground to generate clean geothermal energy, MIT Technology Review noted. Fervo is one of four U.S. companies to land on the list.

Fervo “uses fracking techniques to create geothermal reservoirs capable of delivering enough electricity to power massive data centers and hundreds of thousands of homes,” MIT Technology Review said.

MIT Technology Review said it produces the annual list to draw attention to promising climatetech companies that are working to decarbonize major sectors of the economy.

“Though the political and funding landscape has shifted dramatically in the US since the last time we put out this list,” MIT Technology Review added, “nothing has altered the urgency of the climate dangers the world now faces — we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change.”

In addition to MIT Technology Review’s companies-to-watch list, Fervo has appeared on similar lists published by Inc.com, Time magazine and Climate Insider.

In an essay accompanying MIT Technology Review’s list, Microsoft billionaire Bill Gates said his Breakthrough Energy Ventures investment group has invested in more than 150 companies, including Fervo and another company on the MIT Technology Review list, Redwood Materials.

In his essay, Gates wrote that ingenuity is the best weapon against climate change.

Yet climate technology innovations “offer more than just a public good,” he said. “They will remake virtually every aspect of the world’s economy in the coming years, transforming energy markets, manufacturing, transportation, and many types of industry and food production. Some of these efforts will require long-term commitments, but it’s important that we act now. And what’s more, it’s already clear where the opportunities lie.”

In a recent blog post highlighting Fervo, Gates predicted geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Fervo is one of the pioneers in geothermal energy. Gates and other investors have pumped $982 million into Fervo since its founding in 2017. With an estimated valuation of $1.4 billion, Fervo has achieved unicorn status, meaning its valuation as a private company exceeds $1 billion.

Aside from Breakthrough Energy Ventures, oilfield services provider Liberty Energy is a Fervo investor. U.S. Energy Secretary Chris Wright was chairman and CEO of Denver-based Liberty Energy before assuming his federal post.

Axios reported on Oct. 1 that Fervo is raising a $300 million series E round, which would drive up the startup’s valuation. News of the $300 million round comes as the company gears up for a possible IPO, according to Axios.

Fervo co-founder and CEO Tim Latimer told Axios this spring that a potential IPO is likely in 2026 or 2027. Ahead of an IPO, the startup is aiming for a $2 billion to $4 billion valuation, Axios reported.

The first phase of Fervo’s marquee Cape Station geothermal energy plant in Utah is scheduled to go online next year, with the second phase set to open in 2028. Once it’s completed, the plant will be capable of generating 500 megawatts of power. This summer, the startup said it secured $205.6 million in capital to finance construction of the plant.

Rice University team develops eco-friendly method to destroy 'forever chemicals' in water

clean water research

Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”
