In the second phase of the 'Hydrogen for transport in Europe' (Hylights) project, the focus was set on the views of the representatives of the municipalities and regions involved in nine leading European demonstration projects and one US demonstration project. A short questionnaire was prepared and distributed and there was therefore the possibility of feedback from seven regions/municipalities which could be documented.
The questionnaire contained 11 questions, structured around two topics:
- experiences and lessons learned,
- recommendations.
When asked about their motives for participating in the demonstration project, most of the answers referred to issues such as improving energy security, climate and environment protection as well as gaining independence from fossil fuels.
Other participants intend to pursue technologies other than hydrogen (e.g. Stockholm: electric hybrid ethanol diesel buses), but most are clearly dedicated to hydrogen and are seeking large-scale hydrogen demonstration projects. The regions/municipalities dedicated to hydrogen technologies have a roadmap or strategy plan for the implementation or are currently working on it.
The expected benefits for the regions/municipalities can be environmental, societal and strategic. The environmental and social aspects cover emission reduction of public transport, operation in restricted areas, sticking to regulations (e.g. EURO 6) and reduction of dependence on imports of fossil fuels. Strategic aspects include gaining expertise in the development of a hydrogen infrastructure as a basis for future large-scale hydrogen demonstration projects.
The availability of sufficient financial resources was seen mostly as the largest hurdle/showstopper by most of the representatives. Also missing were (European) regulations, codes and standards as well as adequate communications. Technical issues seemed to play a subordinate role. Capacity of the refuelling infrastructures as well as driving range of the vehicles were the most important issues.
It was recommended that future demonstration projects should aim to increase the number of vehicles involved, enable the up-scaling of the hydrogen refuelling infrastructure, develop safety regulations, to have long-term goals in mind, improve information exchange and to implement less complex structures with respect to accountability.
The driving range and liquid hydrogen storage systems (for buses) were discussed, as well as the improvement of hydrogen compression technologies, the mitigation of bureaucracy and the implementation of large-scale demonstration projects.
The participating region/municipality representatives asked for framework conditions with respect to safety regulations and standards, political support for hydrogen technologies (as in place for photovoltaic technology and low-emission vehicles).
They proposed the implementation of subsidies for hydrogen production, liquefaction, etc., a higher support quota for demonstration activities and greater financial support in general.
