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.

Report: Texas solar power, battery storage helped stabilize grid in summer 2024, but challenges remain

by the numbers

Research from the Federal Reserve Bank of Dallas shows that solar power and battery storage capacity helped stabilize Texas’ electric grid last summer.

Between June 1 and Aug. 31, solar power met nearly 25 percent of midday electricity demand within the Electric Reliability Council of Texas (ERCOT) power grid. Rising solar and battery output in ERCOT assisted Texans during a summer of triple-digit heat and record load demands, but the report fears that the state’s power load will be “pushed to its limits” soon.

The report examined how the grid performed during more demanding hours. At peak times, between 11 a.m. and 2 p.m. in the summer of 2024, solar output averaged nearly 17,000 megawatts compared with 12,000 megawatts during those hours in the previous year. Between 6 p.m. and 9 p.m., discharge from battery facilities averaged 714 megawatts in 2024 after averaging 238 megawatts for those hours in 2023. Solar and battery output have continued to grow since then, according to the report.

“Batteries made a meaningful contribution to what those shoulder periods look like and how much scarcity we get into during these peak events,” ERCOT CEO Pablo Vegas said at a board of directors conference call.

Increases in capacity from solar and battery-storage power in 2024 also eclipsed those of 2023. In 2023 ECOT added 4,570 megawatts of solar, compared to adding nearly 9,700 megawatts in 2024. Growth in battery storage capacity also increased from about 1,500 megawatts added in 2023 to more than 4,000 megawatts added in 2024. Natural gas capacity also saw increases while wind capacity dropped by about 50 percent.

Texas’ installation of utility-scale solar surpassed California’s in the spring of last year, and jumped from 1,900 megawatts in 2019 to over 20,000 megawatts in 2024 with solar meeting about 50 percent of Texas' peak power demand during some days.

While the numbers are encouraging, the report states that there could be future challenges, as more generating capacity will be required due to data center construction and broader electrification trends. The development of generating more capacity will rely on multiple factors like price signals and market conditions that invite more baseload and dispatchable generating capacity, which includes longer-duration batteries, and investment in power purchase agreements and other power arrangements by large-scale consumers, according to the report.

Additionally, peak demand during winter freezes presents challenges not seen in the summer. For example, in colder months, peak electricity demand often occurs in the early morning before solar energy is available, and it predicts that current battery storage may be insufficient to meet the demand. The analysis indicated a 50% chance of rolling outages during a cold snap similar to December 2022 and an 80% chance if conditions mirror the February 2021 deep freeze at the grid’s current state.

The report also claimed that ERCOT’s energy-only market design and new incentive structures, such as the Texas Energy Fund, do not appear to be enough to meet the predicted future magnitude and speed of load growth.

Houston clean energy pioneer earns prestigious Welch Foundation award

Awards Season

A Rice University professor has earned a prestigious award from the Houston-based Welch Foundation, which supports chemistry research.

The foundation gave its 2025 Norman Hackerman Award in Chemical Research to Haotian Wang for his “exceptionally creative” research involving carbon dioxide electrochemistry. His research enables CO2 to be converted into valuable chemicals and fuels.

The award included $100,000 and a bronze sculpture.

“Dr. Wang’s extensive body of work and rigorous pursuit of efficient electrochemical solutions to practical problems set him apart as a top innovator among early-career researchers,” Catherine Murphy, chairwoman of the foundation’s Scientific Advisory Board, said in a news release.

Wang is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice. The department’s Wang Group develops nanomaterials and electrolyzers for energy and environmental uses, such as energy storage, chemical and fuel generation, green synthesis and water treatment.

Wang also is co-founder of Solidec, a Houston startup that aims to turn his innovations into low-carbon fuels, carbon-negative hydrogen and carbon-neutral peroxide. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions.

Solidec has been selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

“Dr. Wang’s use of electrochemistry to close the carbon cycle and develop renewable sources of industrial chemicals directly intersects with the Welch Foundation mission of advancing chemistry while improving life,” Fred Brazelton, chairman and director of the Welch Foundation, said in the release.

Ramamoorthy Ramesh, executive vice president for research at Rice University, added: “We are proud to (Dr. Wang) at Rice. He’s using chemical engineering to solve a big problem for humanity, everything that the Welch Foundation stands for.”

Last year, the Hackerman Award went to Baylor College of Medicine's Livia Schiavinato Eberlin, who's known for her groundbreaking work in the application of mass spectrometry technologies, which are changing how physicians treat cancer and analyze tissues. Read more here.

Houston venture firm invests in Virginia fusion power plant company in collaboration with TAMU

fusion funding

Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.
