Abstract

A previous study on Sunshine to Petrol (S2P), a technology framework to produce liquid hydrocarbon fuels from CO2 and water using a concentrated solar energy source, focused on process development as well as economic evaluation. The study herein presents results from a life cycle assessment (LCA) approach to a comparative analysis of the environmental impacts of S2P-derived and petroleum-derived gasoline. Results reveal that S2P gasoline shows lower impact scores than the conventional gasoline for all evaluated impact categories. Based on the LCA results, we then analyze the environmental benefits including greenhouse gas (GHG) mitigation and external cost savings. We find that if S2P gasoline could be successfully introduced to satisfy the gasoline demand of a sample city, Victorville in east California, 3.6Mt CO2-eq of the greenhouse gas (GHG) emissions (77% of the total regional emissions) would be mitigated based on the current fleet of vehicles. The lighter impact also corresponds to 4.2M$ annual cost savings from avoided environment damage. More generally, for each million vehicles running on S2P gasoline there would be nearly $30M in savings and 335M gallons of gasoline displaced, which in turn results in nearly 25.8Mt of CO2-eq avoided.
