Multi-state techno-economic model for optimal dispatch of grid connected hydrogen electrolysis systems operating under dynamic conditions 2021 Access copy available to the general public Unrestricted The production of hydrogen through water electrolysis is a promising pathway to decarbonize the energy sector. This paper presents a techno-economic model of electrolysis plants based on multiple states of operation: production, hot standby and idle. The model enables the calculation of the optimal hourly dispatch of electrolyzers to produce hydrogen for different end uses. This model has been tested with real data from an existing installation and compared with a simpler electrolyzer model that is based on two states. The results indicate that an operational strategy that considers the multi-state model leads to a decrease in final hydrogen production costs. These reduced costs will benefit businesses, especially while electrolysis plants grow in size to accommodate further increases in demand. info:eu-repo/grantAgreement/EC/H2020/824388/EU/Integrated multi-vector management system for Energy isLANDs/E-LAND This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 824388-E-LAND info:eu-repo/grantAgreement/ES/UZ/Industrial Doctoral Program 2017 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.139 2021 CHEMISTRY, PHYSICAL 43 / 165 = 0.261 2021 Q2 T1 ENERGY & FUELS 38 / 119 = 0.319 2021 Q2 T1 ELECTROCHEMISTRY 8 / 30 = 0.267 2021 Q2 T1 1.201 2021 Energy Engineering and Power Technology 2021 Q1 Renewable Energy, Sustainability and the Environment 2021 Q1 Condensed Matter Physics 2021 Q1 10.0 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Yusta, J.M.
