This study aims to perform a technical, environmental, and economic assessment of long-distance transport (around 10000 km) of green power from Australia to Japan through High Voltage Direct Current (HVDC) submarine power cables by literature studies. A PV power plant generates green power; 8000 GWh annual production is chosen as capacity. For the HVDC value chain, according to the assessments, energy efficiency is 74%. Power loss during cable transport is the key contributor. GHG footprint of power delivered is 112 kg CO2e/MWh compared to 50 kg at the outlet of the PV plant. Capital expenditure (CAPEX) is 29058 M€. At the end of the 10th and 20th years, another 4500 M€ investment is required for battery replacement. Operating expense (OPEX) is 166 M€/y. The technical cost of power produced is 428 €/MWh. Results of sensitivity analysis show that submarine cables length, power loss and lifetime, battery storage system sizing, and power plant availability have a significant impact on the economic and environmental performance of the whole HVDC value chain.
