What Houston energy companies can learn from a new workforce development program

guest column

In Appalachia, a region known for its economic highs and lows, CNX is redefining what success looks like for the region. Through its Mentorship Academy, CNX is not just filling jobs, but creating meaningful careers that keep young people rooted in their communities. This program, designed to bridge the gap between education and the workforce, has been a game-changer for students who might otherwise not come across the same opportunities.

For those of us in Houston and across Texas, the CNX Mentorship Academy offers a powerful blueprint that could be replicated in our own communities. The challenges faced by young people in Appalachia — limited career options, economic downturns, and the pressure to leave home in search of better opportunities — are not unique to that region. Here in Texas, particularly in our rural areas and economically challenged neighborhoods, many young people face similar hurdles. But what if we could offer them the same kind of opportunities that CNX is providing in Appalachia?

At a recent graduation event held at PNC Park in Pittsburgh, the impact of the CNX Mentorship Academy was evident. The students who graduated that day were not just receiving diplomas; they were stepping into new careers and brighter futures. These young people, who had once been uncertain about their paths, are now equipped with the skills and confidence to succeed in high-paying jobs within their own communities.

One of the key takeaways from CNX’s approach is the importance of exposure. In many cases, students simply aren’t aware of the opportunities that exist in their own backyard. As industries like coal and automotive have declined in Appalachia, many young people believed their only option was to leave the region or settle for low-paying jobs. The shale revolution, however, has brought new life to the area, particularly in the energy sector. CNX recognized this and decided to use it as a platform to uplift the next generation.

The Mentorship Academy targets students who might not be on the traditional college-bound track. These are the kids who show up to school every day but don’t necessarily have a clear direction. This approach has allowed the program to tap into the potential of students who might otherwise be overlooked.

What truly sets the CNX Mentorship Academy apart is its hands-on approach. The students don’t just learn about career opportunities; they experience them. Whether it’s through site visits, internships, or working directly with mentors from companies like Evolution and CNX, these young people are getting a real taste of what their future could look like. “It's all about exposure. Like, you know, we can pour all the money into the schools you want... but if they don't have the opportunities to actually see it for themselves, experience it for themselves, it doesn't stick,” another speaker emphasized at the event.

The success stories coming out of the CNX Mentorship Academy are inspiring. One graduate, who initially entered the program disengaged and uncertain, has since become one of its biggest advocates. After securing a job with his preferred company, he’s now leading the charge in getting other students involved, showcasing his newfound leadership skills. “You can have multiple dreams... It's just, you know, being willing to take a risk, step outside and try something new,” he said, reflecting on his journey.

For Houston and Texas as a whole, the CNX Mentorship Academy offers a model worth emulating. The program’s success lies not just in its ability to place students in jobs, but in its focus on preparing them for careers that provide stability and growth. By connecting students with local industries and giving them the tools they need to succeed, CNX is helping to ensure that the next generation of workers is both capable and motivated.

The best part? The CNX Mentorship Academy’s blueprint is open-source, designed to be replicated in other regions. “There is no secret sauce. Everything is wide open... So this can be copied and scaled in Colorado or in Texas or anywhere else where you would want to duplicate this,” the program leaders shared.

As Houston continues to grow and evolve, programs like the CNX Mentorship Academy offer a valuable lesson: success isn’t just about getting a job; it’s about building a career and a future that benefits both the individual and the community. By adopting and adapting this model, we can create similar opportunities for our own youth, ensuring that they too have the chance to stay and thrive in their own backyards.

Houston scientists develop 'recharge-to-recycle' reactor for lithium-ion batteries

reduce, recharge, recycle

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
