The objective of the project GHy-TREMOD was the extension of the transport emission model TREMOD by adding scenarios which consider hydrogen as a source of energy. Therefore, the results of the GermanHy study "Where does the hydrogen in Germany until 2050 come from?" has been transferred into TREMOD and the time horizon has been extended from the year 2030 to 2050. Besides the consideration of direct emissions and fuel consumption (respectively energy consumption), the whole energy chain was taken into account. This includes, for example, the upstream chain for energy production and supply on the basis of the work in GermanHy. TREMOD users can thus calculate exhaust emissions and energy consumption for the traffic sector under the assumption of different fleet compositions and different portions of hydrogen vehicles depending on a chosen energy mix. Thus, the results of GermanHy are made usable indirectly.
