| Summary/Abstract |
Hydrogen as an energy carrier faces challenges such as high costs of hydrogen supply, high cost of fuel cell electric vehicles (FCEVs), and substantial infrastructure requirements. However, leading countries have announced long-term plan and targets in developing hydrogen energy. Should the Association of Southeast Asian Nations (ASEAN) follow up such developments? This study asks if hydrogen-based road transport, especially FCEVs in the fleets of passenger cars, buses, and trucks, could be economically justified in the ASEAN member states. If not, what strategies to take for ASEAN member states? The study applies a well-to-wheel model and a total cost of ownership model to compare the energy consumption, carbon emissions, as well as the costs of FCEVs with those of alternative powertrains. This practice shows the scale of the cost gaps. Subsequently, it estimates the implications of predicted future developments of both hydrogen and FCEVs, in terms of costs and carbon emissions reduced. The results indicate the areas in which FCEVs are most likely to become competitive in the near future, and thus could be targeted and prioritised. By comparing the country-specific results, implications are extended to what policies are most relevant in facilitating the development of hydrogen and fuel cell.
