Sacramento, CA – Thomas Core is the senior project engineer for BMW’s H2 prototype.

It’s a dual energy vehicle – 8 kilograms of liquid hydrogen gives you 125 driving miles, and a regular gasoline gets 300 driving miles.

If you run out of hydrogen the car switches over automatically to gasoline. BMW uses liquid hydrogen because liquid has a higher density, allowing for a greater driving range. If you used 8 kilograms of compressed hydrogen you would need a much bigger tank, leaving you less room in the car.
