> Abstract: [...] This study presents a membraneless EMAR system by fundamentally redesigning the process configuration and using gas diffusion electrodes (GDEs) as both the anode and cathode. [...] A techno-economic analysis estimates a levelized cost of capture of ~$70/tonneCO2, compared to $137/tonneCO2 for conventional EMAR

FWIU the cost is under $50 per ton for capturing concentrated CO2 from industrial sources like power plants or natural gas plants?
