Refuelling of the BMW hydrogen car.
This car is an internal combustion hydrogen car. BMW are leasing it out to 100 high profile users. Hydrogen can be obtained from oil, natural gas, and water. It can be obtained from water through electrolysis.
You may have heard on youtube of cars that run on water - there is no such thing as a car that runs purely on water.
You can buy kits that enable you to run your car on a mixture of water and gas by using the cars battery to convert the water into hydrogen. The efficiency of these kits is under much debate because it uses energy to extract the hydrogen from the water.
