Monolith

Monolith uses proprietary plasma pyrolysis technology to produce low-emission carbon black and hydrogen. The company's process employs renewable electricity instead of combustion to convert conventional, renewable, or responsibly-sourced natural gas into these products with virtually no local emissions. Carbon black, a powdery substance used in tires, plastics, inks, paints, and other everyday products, is traditionally produced through emission-intensive methods. Monolith operates a commercial-scale production facility in Hallam, Nebraska, with research and development facilities in San Carlos, California, Denver, Colorado, and Kansas City, Kansas. The company's first-of-its-kind plasma pyrolysis technology was developed in collaboration with Mines Paris. In February 2024, Monolith renewed its research partnership with Mines Paris through February 2030 to further advance thermal plasma processing innovation. Through the expansion of its Olive Creek facility, expected to be completed in 2026, Monolith aims to produce 194,000 tonnes of carbon black and 275,000 tonnes of clean ammonia annually.

Key customers and partnerships

In late 2021, Monolith established a collaboration with The Goodyear Tire & Rubber Company, marking the first use of low-emission carbon black in tire manufacturing. The carbon black produced at Monolith's existing facility is supplied to tire manufacturers across North America. In October 2021, the company signed a memorandum of understanding with SK to produce clean hydrogen and carbon black in South Korea.
