Students from the University of Technology (TU/e) have converted a bus to run on formic acid. This is a type of fuel they developed themselves. The vehicle will be unveiled on Thursday.
Formic acid is a combination of hydrogen and carbon dioxide. It is produced by ants and other insects. This liquid fuel is sustainable, CO2-neutral and safe.
In the vehicle, the hydrogen-carbon dioxide combination is split in a trailer. The hydrogen is used to produce electricity which propels the bus.
A vehicle can travel for longer on hydrogen than on battery power. Usually, one needs large tanks and high pressure to store this substance, but because it is now part of a liquid, it is easier to transport.
