Mapping CCUS Technological Trajectories and Business Models: The Case of CO2 -Dissolved
Résumé
According to the different climate change roadmaps (IEA, IPCC), Carbon Capture Storage (CCS) will play a key role in the climate change mitigation policy. Its development raises a trade-off between the deployment of large-scale projects (learning by replication), and the preservation of a large portfolio of competing technologies (learning by diversity), on each of its steps (capture, transport, storage). By now large-scale CCS projects are still few, most devoted to EOR (Enhanced Oil Recovery). Although EOR has provided a first feasible business model for CCS, CCS has still to prove its economic viability on a large variety of carbon emitters (power plant, industrial and bioenergy sources). A competing business model for CCS is to find other carbon uses and energy sources, better adapted to medium and small carbon sources. The paper presents such a technological solution, the CO2 DISSOLVED project, which combines CCS in a dissolved state with geothermal energy.
