This paper presents an advanced techno-economic model for calculation of optimal dispatch of large-scale multi MW electrolysis plants in order to obtain a more accurate evaluation of the feasibility of business cases related to the supply of this fuel for different end uses combined with grid services' provision. The model is applied to the Spanish case using different scenarios to determine the minimum demand required from the FCEV market so that electrolysis facilities featuring several MW result in profitable business cases. The results show that grid services contribute to the profitability of hydrogen production for mobility, given a minimum but considerable demand from FCEV fleets.2019http://zaguan.unizar.es/record/7964510.1016/j.ijhydene.2019.05.092http://zaguan.unizar.es/record/79645oai:zaguan.unizar.es:79645info:eu-repo/grantAgreement/EC/H2020/671458/EU/Grid Integrated Multi Megawatt High Pressure Alkaline Electrolysers for Energy Applications/ELYntegrationThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 671458-ELYntegrationinfo:eu-repo/grantAgreement/EC/H2020/736351/EU/Demonstration of 4MW Pressurized Alkaline Electrolyser for Grid Balancing Services/Demo4GridThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 736351-Demo4GridInternational Journal of Hydrogen Energy 44, 33 (2019), 17431-17442by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
