Both the production and the use of hydrogen are topics that attract highest attention in transport sector, responsible for about 30% of world energy-related greenhouse gases (GHG) emissions, while the practical aspects of a hydrogen economy, are rarely addressed. In this work the cost of hydrogen was studied through the design, realization and validation of a solar-powered hydrogen fueling station in smart cities applications. CNR-ITAE together with other industrial partners has developed, under the Italian research project called i-NEXT (innovation for greeN Energy and eXchange in Transportation), the on-site hydrogen production plant. The plant is fed by a microgrid able to receive energy from solar radiation by a 100 kWp rooftop photovoltaic plant and connected with a battery energy storage system of 300 kWh (composed by 16 sodium nickel chloride high temperature batteries) in this way the plant is able to deliver hydrogen and electricity for an electric and hydrogen vehicles fleet. This work compares, through three different case studies coming from a first test campaign, the real cost of hydrogen obtained by using the electricity coming from the main grid (thermoelectric power plants), by using energy from photovoltaic plant and finally by the integration of the battery energy storage system that supports and offsets energy from photovoltaics plant.

Abstract
Both the production and the use of hydrogen are topics that attract highest attention in transport sector, responsible for about 30% of world energy-related greenhouse gases (GHG) emissions, while the practical aspects of a hydrogen economy, are rarely addressed. In this work the cost of hydrogen was studied through the design, realization and validation of a solar-powered hydrogen fueling station in smart cities applications. CNR-ITAE together with other industrial partners has developed, under the Italian research project called i-NEXT (innovation for greeN Energy and eXchange in Transportation), the on-site hydrogen production plant. The plant is fed by a microgrid able to receive energy from solar radiation by a 100 kWp rooftop photovoltaic plant and connected with a battery energy storage system of 300 kWh (composed by 16 sodium nickel chloride high temperature batteries) in this way the plant is able to deliver hydrogen and electricity for an electric and hydrogen vehicles fleet. This work compares, through three different case studies coming from a first test campaign, the real cost of hydrogen obtained by using the electricity coming from the main grid (thermoelectric power plants), by using energy from photovoltaic plant and finally by the integration of the battery energy storage system that supports and offsets energy from photovoltaics plant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
