Techno-economic and environmental assessment of LNG export for hydrogen production

February 8, 2023

A critical requirement of a widely contemplated hydrogen economy is the development of a low carbon hydrogen supply chain that is cost competitive. This comprehensive techno-economic assessment demonstrates, for the first time, the viability of a complete hydrogen supply chain based on the transport of liquefied natural gas (LNG).


– Comprehensive techno-economic assessment of LNG-based hydrogen supply chain.
– An existing LNG trade route between Australia and Japan is considered.
– A competitive total hydrogen supply cost of 2.3 USD/kgH2 was determined.
– Total CO2 emissions intensity of this supply chain is 40 kgCO2/GJ.
– Methods and impact of potential emissions reduction strategies are presented.
