Electrical Energy Storage (EES) has been recognized as a solution to increase the penetration of renewable energy technologies because providing time varying energy management, meeting peak energy demands, meeting remote loads, and improving system reliability [1]. Some recent studies demonstrate that an EES system based on reversible solid oxide cell (ReSOC) technology (HES, hydrogen energy storage) offers a potentially high efficiency, low cost, and scalable distributed energy resource [2-4]. Depending on the cell polarity, the ReSOC can operate either as a fuel cell (SOFC mode) to electrochemically oxidize fuel species (i.e., H2, CO) and generate electricity, or as an electrolysis cell (SOEC mode) to electrochemically reduce reactant species (i.e. H2O and/or CO2) while consuming electrical energy. This paper focuses on the behaviour and performance assessment of a novel and efficient EES system based on solid oxide cell technology, that can operate reversibly either as a fuel cell (SOFC) or as an electrolyser (SOEC). The study is carried out by means of experimental and numerical activity on a 30-cells stack, operating under different working conditions (temperature, fuel electrode and oxidant electrode gas composition, utilization factors, etc.).

Abstract

Electrical Energy Storage (EES) has been recognized as a solution to increase the penetration of renewable energy technologies because providing time varying energy management, meeting peak energy demands, meeting remote loads, and improving system reliability [1]. Some recent studies demonstrate that an EES system based on reversible solid oxide cell (ReSOC) technology (HES, hydrogen energy storage) offers a potentially high efficiency, low cost, and scalable distributed energy resource [2-4]. Depending on the cell polarity, the ReSOC can operate either as a fuel cell (SOFC mode) to electrochemically oxidize fuel species (i.e., H2, CO) and generate electricity, or as an electrolysis cell (SOEC mode) to electrochemically reduce reactant species (i.e. H2O and/or CO2) while consuming electrical energy. This paper focuses on the behaviour and performance assessment of a novel and efficient EES system based on solid oxide cell technology, that can operate reversibly either as a fuel cell (SOFC) or as an electrolyser (SOEC). The study is carried out by means of experimental and numerical activity on a 30-cells stack, operating under different working conditions (temperature, fuel electrode and oxidant electrode gas composition, utilization factors, etc.).
