Table 1 Carbon surcharge for large-scale and small-scale storage options. For a given specific investment cost c_x and carbon ratio α_x. cs_x is the carbon surcharge under the assumption of a storage time of 1 year. n_x is the storage time required for the carbon surcharge to be equal to 75 €/t_CO2 (n = 10 years and i = 5% is assumed throughout)
