Hydrogen is a possible alternative to the internal combustion engine, alongside battery-powered vehicles, in the context of reducing greenhouse gas emissions associated with transport activities. The costs associated with hydrogen vehicles are currently high, even when considering the greenhouse gas emissions and other pollutants avoided by their use. Efforts to reduce these costs, which will determine the social and environmental desirability of hydrogen vehicles, face two challenges: the high cost of refuelling, linked to the crucial problem of coordination between development of the vehicle fleet and refuelling infrastructure; and high purchase prices, which may decrease when sufficient quantities generate experience effects. This paper argues that each of these two handicaps calls for a specific policy design: at a local level for coordination between actors, and at a European level to generate sufficient volumes. The example of hydrogen-powered urban buses analysed through the Joint Initiative for Hydrogen Vehicles across Europe (JIVE) offers a telling illustration of these issues.

This article identifies supply and demand shocks in the oil and gas market using monthly data (from January 2008 to December 2021) and explores their impact on clean energy stock returns in Europe. Our results show that a negative gas supply shock positively affects clean energy stocks, while a negative shock in global oil supply does not have...
