The energy transition has momentum, according to Wogbe Ofori. But there's still a ways to go.

Ofori, the founder and chief strategist of WRX Companies, is an adviser to Nauticus Robotics and strategist to Intuitive Machines and Jacobs, he's also served as a mentor across the local innovation community. He's narrowed in on hardtech and has has gotten a front-row seat to observing what's happening in Houston amid the energy transition, as he explains on this week's episode of the Houston Innovators Podcast.

Listen to the episode and read an excerpt below.

EnergyCapital:Ā Looking back on some of the recent trends of the energy transition, what have you observed?

Wogbe Ofori: The energy transition has been something that ā€” through the last hype cycle that started in the second half of 2020 and lasted until the first quarter of 2022 ā€” was part of that momentum along with Web3. Now, the energy transition is continued as Web3 has fallen off a cliff and now been replaced by AI, but the energy transition is continued. Where I think moving into the next major stage where now itā€™s time for them to actually be proven out. And these things are hard and take time to be proven out and these technologies to mature. Then for the products and services that are derived from them, to really find the right place within the market and the right use cases. The idea that there is some sort of silver bullet ā€” whether it be hydrogen or something else ā€” that's going to solve the problem for all use cases is completely unrealistic. The issue is that a lot of folks especially the big energy players ā€” the O&G majors here ā€” they know that.

EC:Ā So, what does this next stage look like?

WO: Now we're moving into what I think is a really interesting period where it's going to be, ā€œwell do we really have the legs for this race?ā€ Because we sprinted, and everybody got really excited. Now you starting to hear, ā€œwell you know some investors are a little worried that cleantech 2.0 might suffer some of the same fate as cleantech 1.0.ā€ How do we avoid that? Will investors have the patience to continue to make investments into energy transition plays for the longer term, because weā€™re going to need that to make these transitions. It's not going to happen overnight.

EC: Where does Houston come in on all this?

WO: Well the other big question thatā€™s being asked around is, ā€œCan Houston actually lead this?ā€ It's difficult for an incumbent to disrupt itself. Weā€™ve been positioning ourselves as moving from the energy capital of the world to the energy transition capital. I'm all for it, and I'm 100 percent behind it. Now we are just at the place where we're really going to start to see the difference between those who were caught up in the excitement of the energy transition, and those who really have the faith to see this thing through. The ones who do have the faith to see this through are going to create some fantastic companies that are going to create real value and that will materially change the way we live. But itā€™s going to take time and be hard.

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram ā€” compared to the 396 watt-hours per kilogram in older sodium-ion batteries ā€” this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de ReaĢctiviteĢ et de Chimie des Solides, which is a CNRS laboratory part of the UniversiteĢ de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la MatieĢ€re CondenseĢe de Bordeaux, UniversiteĢ de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called ā€œNa superionic conductorsā€ or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

ā€œThe continuous voltage change is a key feature,ā€ Canepa says in a news release. ā€œIt means the battery can perform more efficiently without compromising the electrode stability. Thatā€™s a game-changer for sodium-ion technology.ā€

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
