<p>The objective of this study is to analyze, from a comprehensive perspective, the economic and environmental effects induced by constructing and operating hydrogen utilization systems presented by METI's roadmap. We focused on a marine transport system for hydrogen produced offshore, hydrogen gas turbine power generation, fuel cell vehicles (FCVs) and hydrogen stations, as well as residential fuel cell systems (RFCs). In this study, using an Input-Output Table for Next Generation Energy Systems (IONGES) with newly established renewable energies and hydrogen-related sectors, we evaluated the induced output, labor and CO₂ from construction and operation of these hydrogen technologies using a uniform approach. Initial investments in facilities based in foreign countries that produce hydrogen, transport it through organic hydride, and supply it to a power station of 1 GW capacity yield an induced production of 2.7 times. This investment can exploit a new opportunity for the utilization of unused renewable energy sources that are abundantly available in foreign countries and reduce significant CO₂ emissions. Additional investments in domestic hydrogen supply systems, FCVs, and RFCs yield an induced production of 2.6 times each. From a comprehensive point of view, the construction of a hydrogen utilization system may result in cost and CO₂ reductions.</p>
