Techno-economic evaluation of synthetic natural gas (SNG) and hydrogen containing synthetic natural gas (HSNG) production for future sustainable transport in Germany

Abstract

This work presents a techno-economic assessment of the synthetic CNG and HCNG production in Germany. The objectives of this investigation are: (1) Determining exergy destruction sources of high- and low-temperature methanation processes for the production of CNG, their influence on the plant’s economic performance, and the potential for cost savings, (2) Estimating the effect of the methanation process and the hydrogen content of synthetic HCNG on the process efficiency, plant’s investment costs and NPC, for the posterior optimization of these performance indicators, (3) Determine the economic advantages of synthetic HCNG production compared to synthetic CNG in Germany to estimate its attractiveness for the market.
