Coal-based generation rose by 3 in 2018, the same rate as in 2017, to reach a new peak at more than 10 000 TWh. CCUS-equipped coal generation still accounts for only a negligible share of overall coal generation, as just two plants are currently in operation it is therefore not in line with the Sustainable Development Scenario SDS.
