Goodyear did not go into detail as to what the collaboration entails, saying only it will "help advance Goodyear's work to identify and use more sustainable materials."
"At Goodyear, we're committed to sustainability and making a positive impact by our choice of the materials we use," said Chris Helsel, senior vice president of global operations and chief technology officer.
"Our collaboration with Monolith is one example of how we are using sustainable materials in quality products that deliver a better future," he said.
Monolith Co-Founder and CEO Rob Hanson said the company is proud to support Goodyear's mission to make its tires more sustainable.
"We're honored to work with companies like Goodyear that share our passion for quality products that are responsibly manufactured, and we are eager to see what advancements this collaboration will bring to the tire industry."
Lincoln, Neb.-based Monolith claims to be the first U.S.-based company to produce clean hydrogen on a commercial scale.
The product is the direct result of the methane pyrolysis process, which uses renewable energy in the manufacture of carbon black.
To do so, Monolith uses a natural-gas feedstock. When "superheated" by electricity, the carbon and hydrogen bonds of the natural-gas molecules are broken down, and the pairs of hydrogen atoms and carbon atoms are moved through separate chambers.
The carbon is processed further into carbon black, while "green hydrogen" is directed to end users, with applications for hydrogen trucking, aviation and marine fuel, chemical production, agriculture and energy storage.
The firm has one processing plant in operation, in Hallam, Neb., that is rated to produce 14,000 tons of carbon black and 5,500 tons of hydrogen annually.
