Synopsis of visualization exercises for the selection and operation of the Geothermal Energy Buffer (GEB)
Résumé
By storing a phase change hydrocarbon at depth, our innovation, the Geothermal Energy Buffer (GEB), stores underground thermal energy. Liquid Petroleum Gas (LPG) thermodynamic characteristics, as a heat transfer fluid for thermal storage and as a phase change fluid for energy production, was studied. A model for daily balanced energy inputs and outputs was performed. First results allowed to demonstrate the energetic interest for this type of energy storage, in terms of power and dispatchability. To achieve LPG's production and reinjection a set of wells has been determined and their capital expenditures (CAPEX) estimated. A technicaleconomic analysis exercise has been completed with marketed surface facilities technologies and energy data obtained from the modelling of the system energy inputs and outputs. The study conclusion resulting from the calculations showed that competitive economical results were reached and ways for GEB performance improvement identified.
