Fig. 3: Impact of plant conversions on global stranded generation.

a Coal-to-gas, b carbon capture and storage (CCS) without biomass, c CCS with biomass co-firing at 20%, d CCS with biomass co-firing at 50%. Scatter points represent the estimation from individual models and bars show the model mean. The conversion percentages correspond to the share of coal-fired power plants converted to gas. Those of b–d correspond to the share of CCS suitable plants converted to CCS. Biomass co-firing ratios vary from 0 in b to 50% in d.
