Hydrogen transportation fuel in Croatia: Road map strategy

• It is proposed hydrogen infrastructure based on solar energy and water electrolysis.
• Hydrogen FCEVs were calculated for three phase in the period up to the year of 2030.
• Hydrogen refueling station location sites are proposed on the basis of traffic volumes on selected road directions in Croatia.
• It is solved not only energy storage problem but GHGs emission problem and clean motor fuel for transportation.

In the past 15 years worlds and Croatian economy is faced with the transition from classic primary energy sources to renewable energy sources. It is widely assumed that renewable energy can be stored in the form of hydrogen. Hence, world is faced with roll out of the commercial generation hydrogen fuel cell electric vehicles on the road. Anticipating estimated development there is a question when and how will Croatia keep along with this global scenario?! One of the possible answers, derived from Croatia position as EU country that draws 13% of its GDP mostly from tourists flooding during two summer months, was discussed in this paper. The number of hydrogen fuel cell electric vehicles that could be running by foreign tourists in Croatia up to 2030 was estimated. It was proposed hydrogen infrastructure based on photovoltaic technology of solar energy conversion and water electrolysis as adopted hydrogen production technology. Installed hydrogen infrastructure should be incorporated into national grid power system as renewable energy production, energy consumption, and energy storage subsystem.
