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.

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
