How this 78-year-old Houston chemical company is evolving as an energy tech leader

at the helm

Kendra Lee had no designs on running the family business.

“In fact, I never planned on being a part of Merichem,” Lee recalls.

In 1945, Lee’s grandfather, John T. Files, and a pair of business partners founded the company in Houston. Their goal was to take a potential waste product and turn it into something that would benefit the oil and gas industry — an early attempt at sustainability.

What started as a soap and industrial cleaning company began procuring cresylate, which is a waste from the refineries treating gasoline, to recover spent cresylic acids, which are highly caustic, and refine them so they could be sold into the industrial chemicals market.

“When we were founded, we were a chemical company,” says Lee. “Today, we have morphed into a technology company.”

That transformation began in the 1970s. By 1997, when Merichem put the chemical end of their business into a joint venture with Sasol, the focus had transferred to Merichem Process Technology and Merichem Caustic Services, while Sasol took over the chemical branch.

Merichem Process Technology designs and fabricates equipment for sulfur removal, while Merichem Caustic Services works with companies to handle spent caustic for beneficial reuse rather than waste. The innovative company has more than 1,200 units licensed globally for operation in a myriad of applications. Those allow the 78-year-old company to further push sustainability as a priority.

Lee began her career with Merichem more than 20 years ago as an entry-level laboratory technician.

“I’ve never left, and I kept getting opportunities — now here I am,” she says.

Where she is is at the top of the ladder. Lee became chairman of the board in 2012 and CEO in 2014. But doesn’t think of Merichem as a family business. Lee is only the third member of the family to work at the company, including Files and the cousin who followed him as CEO.

Lee says that she seldom spoke to her grandfather about the business. He worked at Merichem until the day he died in 2002, but Lee recalls that, as a low-level employee, she didn’t have a single meeting with him before that time.

“Our interactions were very normal family dinners,” she explains.

Since her transition into leadership, Lee says, “My focus has really been on continuing the legacy my grandfather and cousin created. We’re very employee-focused and community-focused. Part of our role as part of our industry is to provide livelihoods and be good stewards in communities in which we operate.”

She adds that she’s also focused on innovation.

“That was a big part of who my grandfather was. That’s how we transitioned from being a chemical company to a technology company” she says. That means looking for new methods not only in the research facility, but in every segment of the company.

That eye toward the next big discovery will likely see a significant payoff in one to three years, when a new product, designed to improve on hydrogen sulfide removal — with a new catalyst that is regnerable — will be commercially available. But right now, customers can take advantage of the company’s new Standard LO-CAT® system. The product is the result of continuous improvements from the previous system and boasts low operating costs, no liquid waste streams, and significant turndown capability.

And what will follow for the Houston born-and-based company? Merichem has plans to push further into the renewables field, says Lee, adding that there is a continued need for Merichem’s technology as we transition into other types of energy, including geothermal. More than three quarters of a century after its founding, Merichem is still a company on the forefront.

HETI's new executive director takes the helm

new leader

The Houston Energy Transition Initiative has a new executive director.

Sophia Cunningham assumed the position this month, succeeding the organization's founding executive director, Jane Stricker.

"Four years ago, I could never have imagined the opportunities, experiences and relationships this role has enabled," Strickler wrote in an address earlier this year. "I am truly grateful for the support and engagement of Houston’s business and community leaders, the visionary leadership of Bobby Tudor, Scott Nyquist, HETI Members, and the Greater Houston Partnership in creating this initiative at exactly the right moment in time. I am incredibly proud of the HETI and the Partnership team members who have delivered with purpose and passion, and I greatly appreciate Houston’s energy and climate leaders and champions who have supported my agenda, challenged my thinking, broadened my perspectives, and worked with HETI to demonstrate the power of partnership in developing, innovating and advancing the ideas and technologies needed to meet this challenge for our region and the world."

Stricker shared on LinkedIn that she has joined the advisory board of FluxPoint Energy, which launched last month during CERAWeek, in addition to her other roles at Greentown Labs, Prana Low Carbon Economy Investments and UNC Kenan-Flagler Energy Center.

Cunningham previously served as vice president at HETI, where she was responsible for efforts related to carbon capture, use and storage; methane management; community engagement and stakeholder activation. Before joining HETI, she was director of public policy at The Greater Houston Partnership.

She earned her master's in Energy Management and Systems Technology from Texas A&M University and holds a bachelor's degree from Davidson College.

“I’m honored to step into the role of Executive Director of the Houston Energy Transition Initiative at such a pivotal moment for our industry," Cunningham said over email. "Houston has the talent, infrastructure, and leadership to meet growing global energy demand while reducing emissions, and I’m excited to work alongside our members and partners to accelerate solutions that are reliable, affordable, and scalable.”

The Greater Houston Partnership launched HETI in June 2021 to "meet a Dual Challenge of producing more energy that the world needs with less emissions," according to its website.

Pattern Energy expands clean energy portfolio with acquisition of Canadian producer

acquisition closed

Clean energy and transmission infrastructure company Pattern Energy completed the acquisition of Canadian independent power producer Cordelio Power this month.

Pattern Energy, which is headquartered in San Francisco and has major operations in Houston, will now own one of the largest independent clean energy infrastructure platforms in North America, according to a release.

Pattern Energy will add approximately 1,550 megawatts of operating and in-construction assets, including 16 wind, solar and energy storage projects across the United States and Canada, as part of the deal. In addition, they have also acquired the majority of Cordelio’s development pipeline in key U.S. markets and members of Cordelio’s team.

“Closing this transaction marks a significant milestone for Pattern Energy as we continue to scale our platform to meet North America’s growing energy needs,” Hunter Armistead, CEO of Pattern Energy, said in the release. “Cordelio brings a highly complementary portfolio of quality assets and a talented team. Together, we are even better positioned to power the future.”

Currently, Pattern Energy’s portfolio includes wind, solar and energy storage projects in over 40 facilities in North America. Pattern Energy had 12,000 megawatts of operating and in-construction capacity before the deal.

The acquisition was first announced Jan. 6, 2025.

“Pattern and Cordelio share a commitment to responsible development and the communities in which we work,” Chris Hind, CEO of Cordelio Power, said in a news release. “We look forward to joining with Pattern Energy to deliver high-quality projects with expanded product offerings to support customers across more markets.”


Pattern Energy doubled down on its Houston commercial space in 2023, moving the company's development, meteorological, transmission and energy trading teams to a new office in the Montrose Collective. The company's Operations Control Center is also based in Houston.

Its Houston-based development team was assigned to work on Pattern's SunZia Transmission and Wind project in New Mexico and Arizona, expected to be one of the largest clean energy infrastructure projects in U.S. The project is targeting commercial operations this year, according to Pattern Energy's website.
