A Correction on
Contribution to a standardized economic and ecological assessment methodology for e-fuel production in Germany

by Heimann N, Raab M, Wulff N, Haas S, Pichlmaier S and Dietrich R-U (2025). Front. Energy Res. 13:1297299. doi: 10.3389/fenrg.2025.1297299

Equation 9 in [Section 2.2 line 332] was erroneously given as $[A C C [\frac{€}{a}] = F C I \cdot$ $(\frac{I R \cdot {(1 + I R)}^{y}}{{(1 + I R)}^{y} - 1} + \frac{I R \cdot y}{9})]$ .

The correct equation is $A C C [\frac{€}{a}] = F C I \cdot I R (\frac{{(1 + I R)}^{y}}{{(1 + I R)}^{y} - 1} + \frac{y}{1 - 9} - 1)$ .

Equation 8 in [Section 2.2 line 328] was erroneously given as [ $T C I = F C I \cdot {(1 - w o r k i n g c a p i t a l)}^{- 1}$ ].

The correct equation is $T C I = \frac{F C I}{1 - w o r k i n g c a p i t a l}$

Equation 6 in [Section 4.3 line 559] was erroneously given as $[N P C [\frac{€}{k g}]$ $= \frac{(1.53 + 0.92 + 247.1 + 0.5) \frac{M €_{2018}}{a}}{248, 807.8 \frac{t}{a}} = 1 \frac{€_{2018}}{k g}]$ .

The correct equation is $N P C [\frac{€}{k g}] = \frac{(0.7 + 0.92 + 247.1 + 0.5) \frac{M €_{2018}}{a}}{248, 807.8 \frac{t}{a}} = 1 \frac{€_{2018}}{k g}$ . Its equation number has to updated to (10).

Text correction

[With an assumed interest rate of 5%, see Table 1, and equation (9) the ACC equals 1.53 M€₂₀₁₈ a⁻¹. Given the values of Table 7, the OL results 0.49 M€₂₀₁₈ a⁻¹. In Table 10 the intermediate and the main result of the OPEX_ind calculation is shown].

A correction has been made to the section 4.3 Economic analysis:

“[With an assumed interest rate of 5%, see Table 1, and equation (9) the ACC equals 0.7 M€₂₀₁₈ a⁻¹. Given the values of Table 7, the OL results 0.49 M€₂₀₁₈ a⁻¹. In Table 10 the intermediate and the main result of the OPEX_ind calculation is shown.]”

The original article has been updated.
