Hybrid plug-in battery and hydrogen fuel engine vehicle with swappable hydrogen tanks and method for modular hydrogen storage and transportation and distribution

A hybrid plug-in chargeable battery bank and hydrogen fuel engine vehicle with swappable hydrogen tanks comprises:

• (a) a plug-in chargeable battery bank;
• (b) a hydrogen fuel engine;
• (c) a water electrolysis system;
• (d) multiple swappable modular hydrogen tanks;
• (e) a photovoltaic power generation system;
• (f) and a control system;
• Wherein, the photovoltaic power generation system is electrically coupled to the plug-in chargeable battery bank to charge the battery bank;
• the plug-in chargeable battery bank is electrically coupled to the water electrolysis system to generate hydrogen to charge the swappable modular hydrogen tanks;
• and the hydrogen tanks supply hydrogen to the hydrogen fuel engine through high pressure pipes;
• When in operation, in sunny days, the solar radiation is collected and converted into electric power by the photovoltaic power generation system to store in the plug-in chargeable battery bank for powering the water electrolysis system to generate hydrogen;
• in cloudy days or at nights, the plug-in chargeable battery bank is charged by electric vehicle charging station for powering the water electrolysis system to generate hydrogen, or the swappable hydrogen tanks are directly swapped at hydrogen charging stations or other places to supply hydrogen;
• with constant hydrogen supply, the hydrogen fuel engine is employed to drive the vehicle by combusting the hydrogen.
