Das Projekt "Benchmarking of the European Hydrogen Energy Roadmap HyWays with International Partners (HYWAYS-IPHE)" wird vom Umweltbundesamt gefördert und von Ludwig-Bölkow-Systemtechnik GmbH durchgeführt. Objective: HyWays-IPHE is an SSA to assess and compare the development efforts for the European Hydrogen Energy Roadmap prepared by HyWays with international road mapping or comparative activities of IPHE partner countries. Step 1 aims at an in-depth assessment and comparison of the individual elements of the national/ regional strategies, modelling approaches and experiences in EU & US. This will include infrastructure analysis, stakeholder consultation processes, actor analysis, economic modelling, WtW- & cashflow analyses and interaction between the different types of models used, scenario development, etc. In workshops modellers shall compare their models and experiences to foster a better mutual understanding of the models, facilitate the exchange of the methodologies and endorse the adoption of individual approaches. This may include tasks and goals of expected results, models used, stakeholders involved, process related issues, timelines and progress. A benchmarking between individual models (e.g. for the EU-US case: E3database and H2A+GREET) may be performed. Step 2 aims at broadening its scope within IPHE by involving other IPHE partner countries like J, CN and IND. In workshops these partners will be introduced into the EU-US work and engaged in this process. The deliverables of the project shall be reports presenting the assessment and comparison activities, for both steps. The learning effects for each IPHE partner shall be an important outcome from these comparative and benchmarking exercises leading to common elements of approaches on how to implement hydrogen technologies and infrastructures and to a better alignment of the road mapping activities. Future hydrogen roadmap development and proceeding implementation efforts in these partner countries shall benefit from the results, especially by avoiding mistakes, eliminating redundancies, inefficiencies and removing, unfounded frictions and misunderstandings between the different approaches and underlying drivers.
