Inputs
- CO₂- or sugar-derived C₃ ester or acid
- Ammonia
- Water
- Electricity
How it works
Sustainable inputs. Proven chemistry. One performance product.
Our scalable process is safer than the industry status quo and highly selective for acrylonitrile without toxic impurities like hydrogen cyanide.
Nitrilation
US government-developed process technology converts inputs into Hoigen-C.
Hoigen-C
Impurity-advantaged, carbon-negative acrylonitrile requiring no retooling.
Derivative products
- Polyacrylamide (PAM)
- Ultra-high molecular weight polyacrylonitrile (PAN)
- PAN precursor
Applications

Key milestones
Building the future, one major breakthrough at a time.
Carbon fiber market validation
Demonstrated drop-in monomer performance to produce carbon fiber precursor.
2019 - 2021: Technology selection. Formed the core founding team and spun out technology developed by the US government.
2022: Demonstrated gram-scale production at bench scale.
2023: Initial product validation and pilot scale up. Partially validated Hoigen-C with global water-soluble polymer manufacturers.
2024: Fully commissioned pilot plant. Co-located the Cassini pilot plant™ at Shell Technology Center Houston and completed commissioning.
2025: Industry-first polyacrylamide validation. Demonstrated Hoigen-C performance across 1,500+ water-soluble polymers.
2026: Carbon fiber market validation. Demonstrated drop-in monomer performance to produce carbon fiber precursor.
