Sorbent Mediated Electrocatalytic Reduction of CO2 to Methane

Tech ID: 34102 / UC Case 2024-9C1-0

Brief Description

A groundbreaking technology that efficiently transforms dilute CO2 streams into methane using sorbent materials and electrocatalysis.

Full Description

This technology leverages a novel approach by using sorbent materials to capture CO2 from dilute streams and directly convert it into methane, bypassing the need for energy-intensive regeneration processes. Utilizing an N- heterocyclic carbene sorbent and an iron tetraphenyl porphyrin chloride electrocatalyst, it achieves high Faradaic efficiency in methane production while regenerating the sorbent for reuse.

Suggested uses

  • Renewable energy and green chemistry sectors for sustainable fuel production. 
  • Industrial CO2 emitters looking for cost-effective carbon capture and utilization solutions. 
  • Chemical manufacturing industries seeking new pathways to synthesize valuable commodities from CO2.

Advantages

  • Efficient conversion of dilute CO2 streams to methane with high Faradaic efficiency. 
  • Eliminates the need for energy-intensive CO2 regeneration steps. 
  • Enables the direct use of more economical and readily available dilute CO2 streams. 
  • Generates methane, a valuable commodity and fuel, directly from CO2. 
  • Operates at ambient temperatures and pressures, enhancing energy efficiency and safety.
