8 Definition of Scenarios 211 / Scenario analyses Scenario 211 A: meeting all objectives of the energy concept of the federal government, including 25% reduction of energy consumption (based on end-use energy, 28) ; CO2 reduction by 25: 8%; share of E-mobility to car traffic by 25: 5%; breakthrough of hydrogen vehicles and related infrastructure development. Scenario 211 B: as Scenario A, but no breakthrough of hydrogen in transport, but production and use of synthetic methane in the transport sector and accordingly construction of new capacity to produce the required additional renewable electricity. Scenario 211 C: as Scenario A, but no breakthrough of hydrogen in transport, but full coverage of the car transport services by electric drives (full electric vehicles and serial hybrids). Outlook: Scenario 211 THG95: reaching the upper limit of the target range for the reduction of greenhouse gases in the energy concept (95%) by 26.? Additional use of electricity and hydrogen as chemical energy storage devices for reconversion and required for full supply of renewable heat and transport sectors. 211 Scenario A ': as Scenario A, only a lower power consumption reduction of around 15% by 25 (final energy consumption, based on 28)
