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.

Investment bank opens energy-focused office in Houston

new to hou

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.

Houston cleantech startup Helix Earth lands $1.2M NSF grant

federal funding

Renewable equipment manufacturer Helix Earth Technologies is one of three Houston-based companies to secure federal funding through the Small Business Innovation Research (SBIR) Phase II grant program in recent months.

The company—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—has received approximately $1.2 million from the National Science Foundation to develop its high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial AC units. The company reports that its technology has the potential to cut AC energy use by up to 50 percent.

"This award validates our vision and propels our impact forward with valuable research funding and the prestige of the NSF stamp of approval," Rawand Rasheed, Helix CEO and founder, shared in a LinkedIn post. "This award is a reflection our exceptional team's grit, expertise, and collaborative spirit ... This is just the beginning as we continue pushing for a sustainable future."

Two other Houston-area companies also landed $1.2 million in NSF SBIR Phase II funding during the same period:

  • Resilitix Intelligence, a disaster AI startup that was founded shortly after Hurricane Harvey, that works to "reduce the human and economic toll of disasters" by providing local and state organizations and emergency response teams with near-real-time, AI-driven insights to improve response speed, save lives and accelerate recovery
  • Conroe-based Fluxworks Inc., founded in 2021 at Texas A&M, which provides magnetic gear technology for the space industry that has the potential to significantly enhance in-space manufacturing and unlock new capabilities for industries by allowing advanced research and manufacturing in microgravity

The three grants officially rolled out in early September 2025 and are expected to run through August 2027, according to the NSF. The SBIR Phase II grants support in-depth research and development of ideas that showed potential for commercialization after receiving Phase I grants from government agencies.

However, congressional authority for the program, often called "America's seed fund," expired on September 30, 2025, and has stalled since the recent government shutdown. Government agencies cannot issue new grants until Congress agrees on a path forward. According to SBIR.gov, "if no further action is taken by Congress, federal agencies may not be able to award funding under SBIR/STTR programs and SBIR/STTR solicitations may be delayed, cancelled, or rescinded."

Mars Materials makes breakthrough in clean carbon fiber production

Future of Fiber

Houston-based Mars Materials has made a breakthrough in turning stored carbon dioxide into everyday products.

In partnership with the Textile Innovation Engine of North Carolina and North Carolina State University, Mars Materials turned its CO2-derived product into a high-quality raw material for producing carbon fiber, according to a news release. According to the company, the product works "exactly like" the traditional chemical used to create carbon fiber that is derived from oil and coal.

Testing showed the end product met the high standards required for high-performance carbon fiber. Carbon fiber finds its way into aircraft, missile components, drones, racecars, golf clubs, snowboards, bridges, X-ray equipment, prosthetics, wind turbine blades and more.

The successful test “keeps a promise we made to our investors and the industry,” Aaron Fitzgerald, co-founder and CEO of Mars Materials, said in the release. “We proved we can make carbon fiber from the air without losing any quality.”

“Just as we did with our water-soluble polymers, getting it right on the first try allows us to move faster,” Fitzgerald adds. “We can now focus on scaling up production to accelerate bringing manufacturing of this critical material back to the U.S.”

Mars Materials, founded in 2019, converts captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. Investors include Untapped Capital, Prithvi Ventures, Climate Capital Collective, Overlap Holdings, BlackTech Capital, Jonathan Azoff, Nate Salpeter and Brian Andrés Helmick.
