In this study, we estimate supply potential of carbon-free hydrogen from wind power in Japan using spatial information such as wind speed and the land use. Then, hydrogen supply cost is revealed for every municipality in the Tohoku districts considering hydrogen production to distribution. The estimation indicates that the supply potential of carbon-free hydrogen in Japan is as much as 205 billion Nm3/year. With that amount of hydrogen a fuel cell vehicle can drive 3,030 billion km. When a high-pressure gas transport system is used for delivery of carbon-free hydrogen from each municipalities to Sendai city, the hydrogen supply cost ranges from 159.8 to 257.0 JPY/Nm3, and the average cost is 180.6 JPY/Nm3. If all cost component of carbon-free hydrogen supply system are replaced by the future cost target, the supply cost range decreases to 82.4~137.3 JPY/Nm3 and the average cost is 99.4 JPY/Nm3. The driving cost of fuel cell vehicle by this future hydrogen supply cost ranges 5.60~9.31 JPY/km and the average cost is 6.72 JPY/km. This cost is cheaper than 7.01 JPY/km of the internal combustion engine vehicle fueled with gasoline.
