Flexibilité et interactions de long terme dans les systèmes multi-énergies : analyse technico-économique des nouvelles filières gazières et électriques en France

Abstract : Over the past decade, several new technological pathways have been experimented with a view to reaching national decarbonization targets in France. These include biomethane, synthetic methane from Power-to-Gas, hydrogen, and Carbon Capture and Sequestration (CCS). The potential contributions of these technologies could make it more difficult for stakeholders and public authorities to choose the appropriate solution. In what contexts could these technologies be developed and what are their potential competition/cooperation perspectives?This research analyzes the role of these new technological pathways within the French gas and electricity systems. We propose a long-term, techno-economic assessment of the options at a 2050 horizon applying an optimal paradigm. We analyze the systems balance over several years while addressing the issue of intraday flexibility constraints.To this end, the bottom-up TIMES-FR-GAZEL model has been developed in order to study joint gas and electricity systems optimization with explicit representation of technologies (biomethane production, Power-to-Gas, CCS, etc.).This model allows us to embed trajectory constraints to reach the 2050 horizon. Assessments are conducted based on final energy demand scenarios with contrasted hypotheses on technology availability, decarbonization strategies and energy demand.
