What is a (HFC) Bus?
· A (HFC) electric bus is an electric bus that includes both a hydrogen fuel cell and batteries.
· The hydrogen fuel cell provides all of the energy for bus’s operation, whilst the batteries are there to provide peak power to the motors to meet rapid acceleration and steep gradients.
How does it work?
· The fuel cell power module onboard the bus generates electric energy through an electro-chemical reaction. The only by-products from the process are water and heat, there are no harmful emissions produced.
· Generated electric energy is used to provide electric traction and to keep the batteries charged.
· The by-product heat is utilised to provide passenger hearting comfort.
· Note, the batteries also provide storage for regenerated braking energy.
· All the energy required for the bus to operate is provided by hydrogen stored on board.
Where do you store the hydrogen on the bus?
How long does it take to refuel the bus with hydrogen?
· Typically you will be looking to around 5 to 7 minutes for fill of hydrogen.
Where do you source the hydrogen?
So, will the government experiment with hydrogen fuel cells for an entire town’s bus network?
