The Use of Hydrogen for Traction in Freight Transport: Estimating the Reduction in Fuel Consumption and Emissions in a Regional Context

The Italian National Recovery and Resilience Plan (NRRP) includes, among other measures, investments in hydrogen vehicle refuelling stations, intending to promote the use of fuel cell electric vehicles (FCEVs) for long-haul freight transport. This paper evaluates impact that this action could have on CO2 emissions consumption, focusing a case study Campania region. proposed approach, which can also be transferred geographical contexts, requires implementation road transport simulation model; model is based construction supply model, estimation demand, an assignment procedure computing traffic flows. covers period from 2025 2040, according forecasts NRRP some assumptions effects; moreover, it assumed entirely produced renewable sources (green hydrogen). key findings three different scenarios show savings between 423,832 778,538 tonnes CO2, 144 264 million litres diesel obtained.
