Table 3 Description of the diagnostic scenarios
From: Identifying energy model fingerprints in mitigation scenarios
Scenario name | Carbon pricing | Additional assumptions |
|---|---|---|
DIAG-NPI | National policies implemented | – |
DIAG-C400-lin | Linear, equation (1) (580 US$ t−1 CO2 in 2050) | – |
DIAG-C400-lin-LimBio | Identical to DIAG-C400-lin | Global primary modern bioenergy supply limited to 100 EJ, which is on the lower end of the range given in the Sixth Assessment Report by IPCC32. Maximum European primary biomass use is limited to 7 EJ, which is close to current use33. Biomass imports of Europe set to 0. |
DIAG-C400-lin-LimCCS | Identical to DIAG-C400-lin | CCS (including BECCS and DACCS) limited to 2 Gt CO2 per year globally. Max CCS use in Europe limited to 250 Mt CO2 per year. |
DIAG-C400-lin-LimNuclear | Identical to DIAG-C400-lin | Nuclear power limited to today’s levels and no new constructions are allowed except capacity already under construction. |
DIAG-C400-lin-HighVRE | Identical to DIAG-C400-lin | Set direct LCOE for offshore wind at €30 MWh−1, onshore wind at €20 MWh−1 and solar PV at €10 MWh−1 by 2050. Linear interpolation from current prices. |
DIAG-C400-lin-HighElectrification | Identical to DIAG-C400-lin | Provide emissions-free electricity for demand sectors at €30 MWh−1 (excluding transmission and distribution). |
DIAG-C400-lin-H2 | Identical to DIAG-C400-lin | Provide emissions-free hydrogen for demand sectors at €45 MWh−1 (excluding transmission and distribution). |
DIAG-C400-lin-ResidualFossil | Identical to DIAG-C400-lin | Set fossil fuel primary energy prices at €70 GJ−1 (before carbon pricing). |
DIAG-C400-lin-HighEff | Identical to DIAG-C400-lin | By means of a variety of lifestyle change or high efficiency options (models are free to choose), reach final energy values of 26 EJ in Europe in 2050 including bunkers and non-energy. |
