Guiding analysis in electrochemical CO2 conversion methods via a systems-level perspective

Carbon conversion applied sciences are gaining curiosity as an answer to make the most of captured CO2 and contribute to efforts to cut back greenhouse fuel emissions. This work gives expertise builders with a systems-level perspective of the local weather impacts of electrochemical CO2 conversion merchandise. Completely different makes use of (polymer manufacturing, transportation fuels, and energy technology) of three CO2-based fuels (methane, methanol, and diesel) are in contrast contemplating completely different combos of electrolyzers (water or CO2 electrolysis) and thermochemical strategies. Moreover, the affect of assumptions and trade-offs between environmental and financial efficiency are evaluated in sensitivity analyses, utilizing polymer and diesel manufacturing as examples. Lastly, suggestions are offered primarily based on environmental and financial analyses. The novelty of this work entails the applying and communication of LCA strategies and insights aimed toward serving to builders visualize their expertise within the full provide chain, offering examples of analyzed programs and a set of suggestions that may be generalized and integrated into the event of various applied sciences. Instance suggestions embody contemplating that in initiatives specializing in enhancing the environmental efficiency of electrochemical processes, cell degradation and electrical energy supply are main components. However, for financial efficiency, lifetime is extra essential than cell degradation and electrical energy supply. Electrochemical processes are fairly promising from a local weather change perspective if the enter electrical energy is from a low-carbon supply, if the use section doesn’t contain combustion, if the product is environment friendly for the use chosen (e.g., diesel is extra environment friendly for transportation than different fuels), and if the use has a big market dimension.
