Author Tatsuya Otani experiences refueling, or rather, gas-filling.

Price list at the gas station on the day of the interview. Diesel was 1.439 euros, gasoline (Super/Super Plus) was 1.649-1.689 euros, and natural gas (Erdgas) was 1.059 euros. Super E10 at 1.609 euros is gasoline blended with 10 percent ethanol.
How e-gas works (overview)
How e-gas works: Electricity generated from wind power is fed into the grid.
How e-gas works: Water (H2O) is electrolyzed into oxygen (O) and hydrogen (H). Then, hydrogen (H2) is combined with carbon dioxide (CO2) to produce methane (CH4).
How e-gas works: The produced methane gas (e-gas) is fed into the gas pipeline network across Germany and used for vehicles and homes.

Schematic of the water electrolysis tank. Water is split into hydrogen and oxygen using electricity generated by wind power.
Carbon dioxide is combined with hydrogen obtained from water electrolysis to produce butane gas. This converts weather-dependent wind energy into a storable form.
