New Plastic-to-Hydrogen Technology Targets Green Fuel Cost and Supply Hurdles
Researchers have developed a method to convert unsorted plastic waste into pure hydrogen, offering a potentially cost-competitive solution to revive stalled clean energy investments amid global oil market volatility.
Researchers from the UCLA Samueli School of Engineering and South Korea’s Ewha Womans University have developed a method to convert unsorted plastic waste into pure hydrogen fuel. The Alkaline Thermal Treatment (ATT) process uses a heat trigger to transform common plastics like PET, PE, and PP into high-purity hydrogen with zero carbon emissions. These findings were published this month in the scientific journal PNAS.
Ah-Hyung “Alissa” Park, a professor of chemical and biomolecular engineering at UCLA and co-corresponding author of the study, emphasized the dual benefit of the innovation. “We are solving two urgent global problems at the same time,” Park stated, noting that the approach tackles plastic waste accumulation and the essential need for clean hydrogen to decarbonize energy in a scalable way.
This development arrives as the green hydrogen sector attempts to recover from a severe implementation slump. A study tracking 190 projects over three years revealed that only 7 percent of global capacity announcements were finished on schedule in 2023. High costs and the heavy demand for dedicated renewable energy had previously led the International Renewable Energy Agency to caution against the indiscriminate use of green hydrogen.
Converting waste streams directly addresses the affordability barrier that has long plagued the industry. Earlier this year, separate research in China demonstrated that deriving hydrogen from agricultural waste sugars could drive production costs down to $1.54 per kilogram. At approximately $0.70 per pound, this price point makes clean hydrogen financially competitive with traditional gray hydrogen produced from fossil fuels.
For investors and industrial executives, these scientific advances offer a tangible pathway to revive stalled capital commitments. The technology supports decarbonization in hard-to-abate sectors like steelmaking and shipping without diverting renewable electricity from other critical grid needs.
The renewed research momentum is also being driven by acute energy security concerns. Against a backdrop of extreme oil market volatility and supply disruptions, major economies including the United States, China, and Europe are accelerating hydrogen investments. If waste-to-hydrogen methods can scale commercially, they could provide a critical buffer against fossil fuel dependency.
