Feasibility Study on the Hydrogen Energy Supply Chain for Low Carbon Society

Abstract

A concept of hydrogen energy supply chain is proposed and its feasibility is examined. The hydrogen is derived from abundant brown coal in Australia. Co-produced CO₂ is stored in the CarbonNet, promoted by Australian government. The hydrogen is then liquefied, transported and utilized as carbon free energy in Japan. In the present study, conceptual design for the whole supply chain is conducted to evaluate CAPEX and OPEX. The result shows that the hydrogen CIF cost is 29.7¥/Nm³ (22US$/MMBTU), revealing the feasibility of CO₂ free hydrogen supply chain in economically and technically.
