Assumed life-cycle fuel and carbon prices are given in Table 5. Calculations are based on a discount rate of 3 %/a and 1 %/a escalation rate for fuel costs. Carbon cost escalates from 50 €/t in 2020 to 200 €/t in 2050. However, with 100 % renewable share achieved after 2040, it does not play a role any more by then.
