“…Jensen et al proposed to use SOEC to produce Fischer-Tropsch fuels either using atmospheric or pressurized cells [18,19]. Similar results were published by Becker et al [20], and by Kazempoor and Braun [21], whereas Cinti et al [22] applied co-electrolysis to investigate the eventual convenience of distributed CO and hydrogen production and centralized F-T fuel synthesis. Co-electrolysis has also been studied for the production of chemicals by producing optimal syngas mixtures with the correct CO/H 2 ratio.…”

Electrical energy storage (EES) systems allow shifting the time of electric power generation from that of consumption, and they are expected to play a major role in future electric grids where the share of intermittent renewable energy systems (RES), and especially solar and wind power plants, is planned to increase. No commercially available technology complies with all the required specifications for an efficient and reliable EES system. Reversible solid oxide cells (ReSOC) working in both fuel cell and electrolysis modes could be a cost effective and highly efficient EES, but are not yet ready for the market. In fact, using the system in fuel cell mode produces high temperature heat that can be recovered during electrolysis, when a heat source is necessary. Before ReSOCs can be used as EES systems, many problems have to be solved. This paper presents a new ReSOC concept, where the thermal energy produced during fuel cell mode is stored as sensible or latent heat, respectively, in a high density and high specific heat material and in a phase change material (PCM) and used during electrolysis operation. The study of two different storage concepts is performed using a lumped parameters ReSOC stack model coupled with a suitable balance of plant. The optimal roundtrip efficiency calculated for both of the configurations studied is not far from 70% and results from a trade-off between the stack roundtrip efficiency and the energy consumed by the auxiliary power systems.

“…FischereTropsch (F-T) diesel from coal via gasification is welldeveloped in South Africa, and using biomass as feedstocks has received growing attention in recent years [33]. Catalyst is the key factor of F-T synthesis unit that has a direct impact on reaction condition and products distribution.…”

SUMMARYSolid oxide electrolyzer (SOE) can operate in co-electrolysis mode of H 2 O and CO 2 because of the high operating temperature and the nickel-based fuel electrode material. In this configuration, the fuel electrode is fed with a mix of steam and carbon dioxide that is converted through electrolysis reactions into a syngas that can be further upgraded to other carbon fuels. This technology can lead to interesting scenarios in the field of energy storage and CO 2 reuse. SOE performance in terms of syngas quality and chemical equilibrium is presented in this study. An experimental test on a four-cell stack was performed to evaluate which are the effects of inlet gas composition and current density on the output syngas composition and on the thermal balance of the stack. Results were analyzed with the support of a thermodynamic model that aims to demonstrate that equilibrium condition is reached within the stack for all the involved reactions including reverse water shift. Also, we show that there is a direct relation between inlet and outlet compositions. For each composition, current density for thermoneutral condition was calculated obtaining values in the range of 377-493 mA/cm 2 depending on the composition. Such results permit to study SOE integration in a complete process for energy and CO 2 storage. Copyright
