This paper presents the economics of CO2 free hydrogen in APEC region. The fuel cost of imported CO2 free hydrogen was estimated to be JPY 24-57/Nm3 for power generation, and JPY 26-60/Nm3 for hydrogen refueling station around 2030. However, the hydrogen supply sources in APEC region that can meet the target prices for hydrogen fuel (JPY 30/Nm3 for hydrogen power generation, and JPY 40/Nm3 for hydrogen refueling station) are limited. If cost reduction over the hydrogen supply chain could be realized, fossil fuel + CCS hydrogen imported from APEC region is expected to achieve the target hydrogen fuel prices for both domestic hydrogen power generation and hydrogen refueling station. While in terms of economics, imported renewable hydrogen from APEC region is only viable for the supply to hydrogen refueling station round 2030.
