Storage is a major part of the energy system that's ripe for innovation and disruption — and a research team based partly out of the University of Houston has made a remarkable milestone in capacitor technology.

Researchers from the University of Houston, Jackson State University, and Howard University have created a new type of flexible high-energy-density capacitor, a device that stores energy. For now, the prototype is just 1-inch by 1-inch, but a larger version of the technology can highly impact industries that rely on energy storage or batteries.

The research team explained their project in a paper titled “Ultrahigh Capacitive Energy Density in Stratified 2D Nanofiller-Based Polymer Dielectric Films” published in the journal ACS Nano.

“High-energy and high-power capacitors are essential for a reliable power supply, especially as we shift to using more renewable energy sources," Alamgir Karim, Dow Chair and Welch Foundation Professor of Chemical Engineering at UH and faculty mentor on the team, says in a UH news release. "However, current dielectric capacitors don't store as much energy as other types of energy storage devices such as batteries. The higher power density of capacitors makes them more attractive for a multitude of applications as compared to batteries."

The unique design of the capacitor includes layering polymers with oriented 2D nanofillers — which create a material that's thinner than human hair. The design featured an improved energy storage performance with higher energy density and efficiency than existing technologies.

"Our work demonstrates the development of high energy and high-power density capacitors by blocking electrical breakdown pathways in polymeric materials using the oriented 2D nanofillers," adds Maninderjeet Singh, who earned a Ph.D. in chemical engineering at UH last year and is the first author on the paper along with Priyanka Das from Jackson State University. "We achieved an ultra-high energy density of approximately 75 J/cm³, the highest reported for a polymeric dielectric capacitor to date."

Once scaled, the technology has the potential to enhance energy storage in electronics, electric vehicles, power systems, and more.

Houston American Energy Corp. (NYSE: HUSA) plans to break ground on its new advanced recycling facility in the Cedar Port Industrial Park in Q4, the company shared in an announcement this week.

The company acquired a 25-acre, $8.5 million site for development in July from TGS Cedar Port Partners, which handles approximately 5 billion pounds of plastic resin annually. HUSA also plans to build the Abundia Innovation Center on the site.

HUSA named Houston-based Corvus Construction Company the design and construction partner on both projects.

“The site at Cedar Port is in the largest master-planned rail and barge served industrial park in the United States with direct access to the Houston Ship Channel and the Port of Houston,” Ed Gillespie, CEO of HUSA, said in a news release. “It provides robust logistical advantages for the transportation of both feedstock and our low-carbon drop-in fuels and chemical products. Critically, the region has a deep pool of engineering and operations talent. HUSA looks forward to working with local communities and adding economic growth in the Gulf Coast region.”

The new advanced recycling facility will convert plastic waste into pyrolysis oil and will serve as a hub for a five-year development plan designed to scale production capacity.

The facility will be built around New York-based Abundia Global Impact Group LLC’s technologies and proprietary pyrolysis process, which converts plastic and certified biomass waste into high-quality renewable fuels.

HUSA acquired AGIG this summer. At the time, the combined company shared that it planned to serve a multi-billion-dollar global demand for renewable fuels, Sustainable Aviation Fuel (SAF) and recycled chemical feedstocks.

The Abundia Innovation Center is planned to serve as a state-of-the-art research and development facility for the renewable energy sector, aiding in the commercial and technical validation of new technologies. HUSA previously announced that Nexus PMG, also based in Houston, will provide strategic support and guidance in the development of the innovation hub.

According to HUSA, the recycling facility and innovation center will “create the foundation for HUSA’s long-term vision to be a leader in the low-carbon fuels sector by driving collaborative innovation.”
