A bio-physical and net-energy comparison of CCS and renewable energy baseload systems
May 22-26, 2017
While CCS is considered a key component for climate change mitigation, actual installed capacity to date creates concerns about its ability to scale sufficiently fast. In the face of this lag, a considered complementary trajectory is for CCuS to play a role in later phases as a way to actively reduce CO2 emissions in combination with biomass. This paper discusses an alternative option: under which circumstances would simply eschewing fossil-based CCS and readily switching the energy system to abundant renewable energy (RE) resources be preferable? We discuss the relative merits of CCS vs RE investments using net-energy as the primary metric but also provide ancillary considerations on the utilization pathway, geological, and infrastructural requirements
