Universidad de Zaragoza Future applications of hydrogen production and CO2 utilization for energy storage: Hybrid Power to Gas-Oxycombustion power plants 2017 Access copy available to the general public Unrestricted Power to Gas (PtG) has appeared in the last years as a potential long-term energy storage solution, which converts hydrogen produced by renewable electricity surplus into synthetic methane. However, significant economic barriers slow down its massive deployment (e.g. operating hours, expensive investments). Within this framework, the PtG-Oxycombustion hybridization can palliate these issues by improving the use of resources and increasing the overall efficiency. In this study we assess the requirements for electrolysis, depending on the size of the oxycombustion plant, the fuel physical and chemical properties and the final application of the hybrid system. Most suitable heat demanding options to implement this PtG-Oxycombustion hybridization are district heating, industrial processes and small combined cycled power plants. The latter case is modelled and simulated in detail and thermally integrated. The global efficiency of this hybrid system increases from 56% to 68%, thanks to avoiding the requirement of an air separation unit and integrating up to 88% of the available heat from methanation in a LP steam cycle. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.229 2017 CHEMISTRY, PHYSICAL 42 / 146 = 0.288 2017 Q2 T1 ENERGY & FUELS 24 / 97 = 0.247 2017 Q1 T1 ELECTROCHEMISTRY 8 / 28 = 0.286 2017 Q2 T1 1.116 2017 Condensed Matter Physics 2017 Q1 Energy Engineering and Power Technology 2017 Q1 Fuel Technology 2017 Q1 Renewable Energy, Sustainability and the Environment 2017 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Kezibri, N.
