Mars Materials is rethinking how critical chemicals are made, using captured CO₂, water, electricity and low-carbon ammonia to produce carbon-negative alternatives to petrochemical feedstocks. In the latest CC Pod, host Noah Margo-Dermer spoke with co-founders Aaron Fitzgerald, CEO; Kristian Gubsch, CTO; and Trey Sheridan, VP of Product and Operations about the company’s mission to build a domestic pathway to materials that today depend on fossil fuels and globally distributed supply chains. Its core product, Hoigen-C, is an industry-validated alternative acrylonitrile monomer, a chemical used in carbon fiber, polymers, and other industrial materials. Mars Materials’ proprietary thermocatalytic process converts CO₂ into useful chemical products, with its pilot facility now producing Hoigen- C as the company works toward larger-scale demonstration. The goal is not simply to decarbonize an existing product, but to unlock new materials and applications around a different chemical feedstock. The opportunity reflects a broader shift in industrial manufacturing. Chemical production and the expertise required to scale it have increasingly moved overseas, creating supply-chain vulnerabilities and an opportunity to rebuild domestic capacity. Demand for carbon fiber and advanced materials across automotive, infrastructure, energy, and dual-use applications adds to the opportunity as manufacturers seek more resilient, lower-carbon supply chains. Mars Materials is now focused on moving from pilot to commercial scale through technology development, manufacturing partnerships, site selection, and demonstration facilities. The company is also building a network of partners with experience scaling chemical technologies from bench to pilot to demonstration. Its longer-term ambition is to turn Hoigen-C into a platform for producing a broader range of materials from CO₂. The vision ultimately stretches from everyday products to interplanetary manufacturing. Mars’ atmosphere is roughly 95% CO₂, making it a natural inspiration for a future where carbon dioxide becomes an industrial resource rather than a waste stream. Hoigen-C is named after the probe that identified naturally occurring acrylonitrile on Saturn’s moon Titan, capturing the company’s broader ambition: to make it rain this critical monomer, safely, and build a new generation of carbon-based manufacturing.
