Dual Pressure Level Methanation of Co‐SOEC Syngas
Research output: Contribution to journal › Article › Research › peer-review
The objective of this article is to demonstrate significant efficiency and performance improvements by simple process modifications of a power to gas plant consisting of high‐temperature coelectrolysis and catalytic methanation. For the advanced process design dual step methanation with two different pressure levels including intermediate compression is proposed, leading to several advantages. By experimental investigations on a lab‐scale methanation test plant higher turnovers (increase of up to 7.1 percentage points) and lower temperature peaks (decrease by up to 130 K) can be proven. Basic energy balance calculations reveal furthermore a reduction in compressor power by 42% for this proposed system.
