Key Points

The aim is to create an efficient system for producing e-methane from carbon capture and green hydrogen.
Developed a novel network for carbon capture and utilization with optimised production rates.
Combined analysis of breakeven costs with life cycle environmental impacts.
Evaluated the cost increase associated with environmental optimisations.
Optimisation of production rates resulted in only a 2% increase in e-fuel costs while minimizing environmental impacts.

Abstract

• Carbon Capture and Utilization converts green H2 and industrial CO2 to e-fuels. • CO2 capture and H2 production rates were optimised in a novel e-methane network. • Optimisation combines breakeven costs with life cycle environmental impacts. • Optimising both costs and environmental impacts increases e-fuel costs by only 2%.
