What Susteon does
Susteon is a private carbon management technology company founded in 2018 and headquartered in Cary/Morrisville, North Carolina, that develops decarbonization materials and reactors for industrial and power-sector customers. The portfolio addresses point-source CO2 capture (Sustenol, a patented water-lean mixed-amine solvent that has reached TRL 5-6 with a stated $45/ton CO2 capture cost on natural gas combined cycle flue gas), direct air capture (EcoFilter), electrified reactor platforms (ERSC, EcoReactor), and CO2-to-products conversion (ECHO, ARCUS, HYPYR) including a sustainable aviation fuel pathway (ECHO-SAF). The underlying technology platform is described as an AI-powered discovery capability that compresses materials R&D timelines from years to months, supported by a pipeline of 55 project ideas narrowed to 4 pilots built and 4 licensed. Sustenol is protected by US Patent 12,172,125 (Notice of Allowance granted October 2024).

Susteon product offering
Product offeringCore offering
Susteon develops and commercializes decarbonization materials and platforms for industrial carbon management. Its core offering centers on Sustenol, a patented water-lean mixed-amine CO2 capture solvent, alongside the ERSC (Electrically Resistive Structured Catalyst) electrified reactor platform, the EcoFilter modular direct air capture unit, and dual-function materials for combined capture-conversion. The company also provides R&D services, custom catalyst/sorbent creation, and technology licensing to industrial emitters and fuel producers.
Product overview
Susteon develops and commercializes decarbonization technologies organized into two integrated segments: Carbon Capture (EcoSolvent/Sustenol solvent, EcoFilter direct air capture, DFM dual function materials, ECCO electrified CO2 concentrator) and Carbon Conversion (ERSC electrified reactor platform, ECHO olefins production, ARCUS syngas production, HYPYR hydrogen from methane pyrolysis). The portfolio is powered by an AI discovery platform that accelerates R&D from years to months. The core products are Sustenol (a patented mixed-amine CO2 capture solvent) and the ERSC electrified reactor platform, with additional technology platforms at various TRL stages. The company offers R&D, engineering, and licensing services for chemical processes and materials.

Targeted at power plants, cement, steel, refinery, and chemical plant operators.
- ERSC (Electrically Resistive Structured Catalyst) / ECOReactor An electrified reactor platform leveraging Joule heating to operate from 60°C to 900°C with >90% thermal efficiency and 5 MW/m³ volumetric heating density. Used as the foundation for CO2 conversion to syngas/olefins and for hydrogen production via methane pyrolysis.
- EcoFilter A modular, low-cost direct air capture (DAC) unit designed to be deployed at ambient conditions. At TRL 4, positioned as a commercially manufacturable DAC solution for distributed carbon removal.
- DFM (Dual Function Materials)
Quantifiable outcome
- 44% lower CO2 capture cost ($45/ton vs state-of-art)
