Abstract
Co-electrolysis of CO2 and steam using solid oxide electrolysis cells (SOECs) can produce syngas (CO and H2 mixture with various ratios), which is further utilized for the synthesis of hydrocarbon fuels using a catalyst. The combination of SOEC and catalytic fuel synthesis processes can offer an environmentally friendly fuel production process. Ni with yttria-stabilized zirconia (Ni/YSZ) is a typical material utilized for SOEC fuel electrodes. Additionally, Ni metal on YSZ support can also be used as a catalyst for methane production (methanation). In this study, a Ni/YSZ-based tubular electrochemical reactor is developed for the methanation process. The correlations between electrochemical and methanation properties of the prepared reactor will be reported in this presentation.This study is partly based on results obtained from a project, JPNP21022, commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
