Why this organization is focused on cultivating the future of energy transition innovation

Q&A

"Our mission is to create the next generation of energy transition climatetech entrepreneurs and intrapreneurs — they don’t all have to start companies," he says on the Houston Innovators Podcast.

Listen to the show below and read through a brief excerpt from the episode with Pruner.

EnergyCapital: Can you share a little bit about the origin of TEX-E?

David Puner: There were a variety of factories that led to its creation, but the seminal event was a piece of work that had been done for the Greater Houston Partnership by McKinsey on the future of Houston. It showed that if Houston isn't careful and doesn't make sure to go ahead and transition with this energy expansion we’re seeing, that they’re at risk of losing hundreds of thousands of jobs. If they catch the transition right and make the conversion to cleaner and low-carbon fuels, they can actually gain 1.4 million jobs.

It was this eye opener for everyone that we need to make sure that if the energy transition is going to happen, it needs to happen here so that Houston stays the energy capital of the world.

David Baldwin (partner at SCF Partners) literally at the meeting said, “listen I've got the beginning of the funnel — the universities, that’s where innovation comes from.” From that, TEX-E was born.

EC: How are you working with the five founding universities to connect the dots for collaboration?

DP: In the end, we have five different family members who need to be coordinated differently. The idea behind TEX-E is that there's plenty of bright students at each of these schools, and there's plenty of innovation going on, it's whether it can grow, prosper, and be sustainable.

Our main job is to look to connect everyone, so that an engineer at Texas A&M that has an idea that they want to pursue, but they don't know the business side, can meet that Rice MBA. Then, when they realize it's going to be a highly regulated product, we need a regulatory lawyer at UT — we can make all that happen and connect them.

At the same time, what we found is, no one school has the answer. But when you put them together, we do have most of the answer. Almost everything we need is within those five schools. And it's not just those five schools, it really is open to everyone.

EC: As you mentioned before, TEX-E started as a way for Houston to take the reins of its energy transition. What's the pulse on that progress?

DP: I spent the last decade building boards and hiring CEOs for all kinds of energy companies and there was the period I would say — pre-pandemic and a little bit into the pandemic — where not everybody was on board with climate change and the issue of carbon. The nice thing now is that’s fully in the rearview mirror. There’s not really a company of any size or a management team of any major entity that doesn’t fully believe they need to do something there.

The train has fully left the station — and picked up speed — on this whole issue of transition and climate. So, that’s been nice to see and create a lot of tailwinds.

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.
