 | Policy space vs solutions space | See ‘Solutions space’ blog for details. The red vertical line shows the current CCS capacity which is negligable. The red horizontal line shows the current renewable electricity capacity which will rise to meet the purple line by 2050. The key story here is the distance between the realistic view of 2050 – the left part of the purple line – and the current policy being discussed in the UK which is based on an unrealistic scaling of both CCS and renewables. |
