Adaptive Reverse Water Gas Shift (RWGS) Reactor

• This modular, electrified reactor enables the conversion of CO₂ and hydrogen into syngas, a precursor for fuel synthesis.
• TRL 5-6.

Dual Function Materials (DFM)

• A combined adsorbent and catalyst system that captures and converts CO₂ cyclically.
• Suitable for point sources and direct air capture.
• TRL 2-3.

Electrified CO₂ Concentrator (ECCO)

• Featuring a hydrophobic sorbent.
• For CO₂ capture and regeneration through an air-sweep process at low temperatures.
• Targeting DAC applications for NGCC plants.
• TRL 2-3

Hydrogen Production via Pyrolysis of Natural Gas

• Utilizing ERSC technology, the system achieves >90% conversion of natural gas to hydrogen and solid carbon.
• Target cost for hydrogen production at $1/kg.
• TRL 5-6.

PROJECTS

Electrified CO₂ Hydrogenation to Olefins for Sustainable Aviation Fuel (ECHO-SAF)

July, 2024

• Recently awarded ARPA-E funding for a three-year development program, ECHO-SAF is designed to produce kerosene-range hydrocarbons.

• Key collaborations with Purdue University and the Aviation Climate Taskforce are essential to optimizing catalyst design and reactor technology.

ROADMAP

• Susteon is prioritizing the scale-up of its point-source CO₂ capture solvent (Sustenol™) and expects pilot trials to complete by mid to end-2025.

• They aim to advance their DAC technology at the NCCC by 2025 August, working on refining the commercialization pathways for each product.

As an incubator, Susteon’s business model is flexible and varies by product. Their primary focus is on developing, testing, and refining climate technologies up to a commercial readiness level. Depending on the application and business partnership, Susteon adapts its commercialization approach. They may:

• Directly sell products, such as Sustenol™ solvent, where they handle manufacturing and sales for customers needing a drop-in solution for CO₂ capture.

• Spin off technologies into separate entities, as with Sustaera, when a product line or technology area has distinct applications and potential for growth as an independent company.

Susteon’s core innovations focus on maximizing efficiency through electrification and tailored catalytic processes:

• Electrified processes: most of Susteon’s technologies operate using electricity rather than traditional heating.

• Joule heated reactor: Susteon’s Joule-heated reactor operates from 60°C to 900°C, supporting versatile applications from DAC to methane pyrolysis.

• Custom catalyst development: the company has developed catalysts optimized for handling various CO₂ types and sources.

• Single-step carbon capture and utilization integration: Technologies like ECHO and DFM enable direct CO₂-to-product conversion.

Sustenol - Solvent

• Sustenol™ is a patented, water-lean mixed amine solvent designed for CO₂ capture from industrial and power generation flue gases.

• It can replace existing amine-based solvents without requiring modifications to equipment or processes.

• It achieves over 97% CO₂ removal.

• It exhibits low degradation and corrosion rates and is thermally stable up to 150°C.

Susteon’s technology could be apply for:

• Industrial CO₂ Emission Reduction: Technologies like Sustenol™ and the ECCO concentrator support CO₂ capture and utilization.

• Sustainable Fuel Production: Susteon’s ECHO-SAF process, which uses CO₂, H₂, and renewable electricity, enables the production of sustainable aviation fuel (SAF).

• Direct Air Capture (DAC): The dual function materials and ECCO concentrator support DAC.

• Hydrogen Production: Producing H₂ from methane pyrolysis with potential uses in green fuel applications.
