This study assessed the techno-economic performance and life cycle greenhouse gas (GHG) emissions for various liqueﬁed natural gas (LNG) supply chains in China in order to ﬁnd the most efﬁcient way to supply and use LNG. This study improves current literature by adding supply chain optimization options (cold energy recovery and hydrogen production) and by analyzing the entire supply chain of four different LNG end-users (power generation, industrial heating, residential heating, and truck usage). This resulted in 33 LNG pathways for which the energy efﬁciency, life cycle GHG emissions, and life cycle costs were determined by process-based material and energy ﬂow analysis, life cycle assessment, and pro- duction cost calculation, respectively. The LNG and hydrogen supply chains were compared with a reference chain (coal or diesel) to determine avoided GHG emissions and GHG avoidance costs. Results show that NG with full cryogenic carbon dioxide capture (FCCC) is most beneﬁcial pathway for both avoided GHG emissions and GHG avoidance costs (70.5e112.4 g CO2-e/MJLNG and 66.0e95.9 $/t CO2-e). The best case was obtained when NG with FCCC replaces coal-ﬁred power plants. Results also indicate that hydrogen pathways requires maturation of new technology options and signiﬁcant capital cost reductions to become attractive.© 2021 The Author(s). Published by Elsevier Ltd.
