Abstract:

An increase in electricity production from Renewable Energy Sources (RES) requires a consequent reinforcement of the transmission and distribution grids to deliver the energy towards the end-users. Since this has a great economic impact, a possible solution is the hydrogen production to be converted in electricity through fuel cells. This process has a low efficiency, but can be suitable for transportation, both for railway and road applications. The aim of this paper is to compare the energy efficiency of the hydrogen applied directly in a fuel cell vehicle or converted in electricity for a fast charge of a battery electric vehicle in long distance journeys.
