Demands for carbon-free vehicles are also increasing in the automobile industry. As a result, an electric vehicle driven by a battery or fuel cell and an internal combustion engine vehicle driven by e-fuel or biofuel have been developed. However, all options are faced with several problems. Battery for EV is expensive and requires metals and some electricity is already based on fossil fuel. FCV needs many hydrogen gas stations, but they are not ubiquitous yet E fuel and biofuel are not in practical use. At the present, EV is the most promising candidate for zero-emission vehicles. However, various technologies should be approached because “technology develops discontinuously.”
