SOEC efficiency

SOEC modules can operate in three different modes: exothermic, endothermic and thermoneutral. In exothermic mode, the stack temperature increases during operation due to heat accumulation, and this heat is used for inlet gas preheating. Therefore, an external heat source is not needed while the electrical energy consumption increases. In the endothermic stack operation mode, there is an increase in heat energy consumption and a reduction in electrical energy consumption and. SOEC already offers impressively higher efficiency level (93%, higher heating value) than other electrolyzers [3]. The electrical efficiencies could be increased upto 97 % by integrating derived heat and thermal coupling to exothermal processes such as chemical methanation [3]. As the temperature increases, lower electrical input is required increasing the electrica high value hydrogen. This feature enables an SOEC system with extremely high electricity-to-hydrogen conversion efficiency, which is not feasible by conventional low temperature electrolysis. The project work plan, focused on achieving the techno-economic targets, includes research and development in A Solid Oxide Electrolysis Cell (SOEC) is basically the corresponding fuel cell (Solid Oxide Fuel Cell - SOFC) run in 'reverse'. Such a cell operates at relatively high temperatures (700-1000 °C), which makes the efficiency very high. The two electrolysis products, hydrogen and oxygen, are formed on each side of the cell

An SOEC system with a higher maximu In general, SOEC systems have higher efficiency on hydrogen production compared to other technologies (e.g., PEM electrolysis), thanks to the thermodynamically more favourable operating conditions. However, they require heat at high temperature, which might not be easily available

Das SOEC-Modul kann in drei verschiedenen Betriebsarten betrieben werden: thermoneutral, exotherm und endotherm. Im exothermen Modus steigt die Stapeltemperatur während des Betriebs aufgrund des Wärmestaus an und diese Wärme wird zum Vorwärmen des Einlassgases verwendet. Daher wird die externe Wärmequelle nicht benötigt, während der Stromverbrauch steigt. In dem endothermen Stapelbetriebsmodus gibt es eine Zunahme des Wärmeenergieverbrauchs und eine Verringerung des. The SOEC UNIT uses mPower's Solid Oxide Electrolysis Cells (SOEC) technology, the most energy efficient electrolysis technology.

SOECs use solid ion-conducting ceramics as the electrolyte, enabling operation at significantly higher temperatures. Potential advantages include high electrical efficiency, low material cost and the options to operate in reverse mode as a.

Solid-oxide electrolysers operate between 650-1000 °C and already offer impressively higher efficiency level (93%, higher heating value (HHV)) than other electrolyzers. The electrical efficiencies could be increased up to 97 % (HHV) by integrating derived heat and thermal coupling to exothermal processes such as chemical methanation The theoretical SOEC electrical efficiency is close to 100 % for hydrogen production efficiency around 90 %. Figure 1: Energy demand of hydrogen operation versus operation temperature (Doenitz, W., et al., International Journal of Hydrogen Energy, 1980. 5: p. 55.). Three operating modes can be distinguished for a HTE system: thermoneutral, endothermal, and exothermal as shown in Figure 2. The In SOEC operation an electrical efficiency of 94.2% at a steam conversion of 70% was achieved. These initial performance values are high compared to literature values. During 3,370 h of SOEC operation at 820 °C and 70% SC, the stack remained gas‐tight and the electrolysis voltage increased by +0.5% k Thus, SOEC is probably more efficient than the already commercialised low temperature electrolysers, and today's SOFC should be tested in the SOEC mode in order to assess the commercial potential of the technology in this application. 3.
