Battery EVs use batteries as their primary energy source, so they are emission-free and can be called "zero emission" vehicles. Even with the energy efficiency of power plants taken into account, these vehicles still have an efficiency of 30%-55% with better performance compared to 15%-20% of vehicles with traditional internal combustion engine. Therefore EVs are more energy efficient than traditional petrol vehicles and save fuel costs.
Furthermore, the electric motor of EVs can output the maximum horsepower at low motor speed, whereas vehicles with traditional internal combustion engines can only output the maximum horsepower at high engine speed. The acceleration performance of EVs at the start is better than traditional petrol vehicles. Unlike petrol vehicles, EVs do not have combustion engines, so noise and vibration during operation are significantly reduced, meaning quieter and more stable driving. Moreover, EVs are emission-free and help improve roadside air quality.

成本效益比較通常取決於多種因素，例如燃料種類、產生的能量和排放物的性質、設施成本等等。雖然燃料電池的成本通常較高，但它們可能比燃燒燃料更具環境友好性和可持續性，這些因素也需要納入考慮。
此外，燃料電池技術仍處於發展階段，預計未來幾年會隨著技術進步和產量增加而降低成本。然而，目前的燃料電池車輛對於大多數人來說可能仍然是一個較昂貴的選擇。
最後，對於是否擁有無限金錢入氣這一問題，無論您的財富狀況如何，仍然需要考慮燃料電池車輛的成本效益以及環境和可持續性因素。

其餘有玩氫氣車嘅廠同款維基有記錄，點解唔出名應該係話氫氣比電難普及，但係氫氣價格已經不停跌緊，所以只要政府肯搞就會越嚟越多。
當初電車插電都搞咗好耐，傳統車廠如果有辦法搞掂，現有加油站就可以直改做賣氫氣。石油有限同受制於出產地，但係氫氣係每個國家都整到，係國家安全層面就更有動力去推。
