Correction to: On the energetic efficiency of producing polyoxymethylene dimethyl ethers from CO₂ using electrical energy (Energy and Environmental Science (2019) 12 (1019-1034) DOI: 10.1039/C8EE02849D)

In the original manuscript, we interpreted ref. 53 wrongly and took the heat demand of post-combustion capture as 1.33 MJ per kg CO2. However, the correct value should be 3.33 MJ per kg CO2. The correction of this mistake leads to slight changes in the numerical results of the paper. (The conclusion and the discussion remain unchanged.) The following sections of the manuscript should be corrected as follows, with the changes indicated in bold: Section 3.1: "Hence, 3.33 MJ heat needs to be supplied. . ." Section 4.2.1: "For Scenario S1, CC via PCC leads to a roughly 6 MJ (+10%) larger thermal energy demand. . ." Section 4.2.2: "When PCC is used, its heat demand is partly covered in scenario S2 by the excess heat of the MeOH synthesis and 2.8 MJ heat has to be supplied additionally." Section 4.2.2: "In scenario S3, the excess heat of the MeOH synthesis is also needed in the OME3-5 synthesis. Hence, the heat demand for PCC is only partially covered. A remainder of 5.4 MJ for route A and 5.5 MJ for route B has to be supplied externally for PCC." Section 4.3: "The supply of CO2 via PCC has a small negative effect on the efficiency in scenarios S1 and S3, resulting in efficiency drops of about 3 percentage points. In Scenario S2, the additional heat demand is partly covered by excess heat from the MeOH synthesis, therefore there is only a small effect on the efficiency when compared to CPS (about 1.5 percentage points)." The Fig. 5 and 7 should appear as follows, both corrected for all PCC options. (Figure Presented).
