One solution to solve a global warming and a fossil fuel depletion is to install the power generation system using renewable energy more. However, Japan does not high potential to install the power generation system using renewable energy compared to the other countries, while more energy can be obtained by installing it overseas, where the potential is higher. In this study, we propose a new smart network model consisting of large-scale photovoltaic (PV) installed in Kolkata, India, which obtains superior solar radiation compared to Japan. The electricity generated from PV is used to produce H2 via water electrolyzer. The produced H2 is then converted into liquefied H2, methylcyclohexane (MCH), liquefied CH4, and liquefied NH3. After that, they are transported to Japan. We propose that these H2 carriers are utilized as a fuel for proton exchange membrane fuel cells (PEFC) system, NH3 gas turbines and LNG gas turbines for power generation in Japan. We evaluate the energy efficiency and the amount of CO2 emission control for the whole process. As to the energy efficiency, it is revealed that the power generation by LNG gas turbines after liquefied CH4 transportation is the optimum. Regarding CO2 emission reduction, it is clear that the power generation by PEFC system after liquefied CH4 transportation is the optimum.
