Hydrogen fuel cell buses have historically been significantly more expensive to purchase and operate than diesel, hybrid or electric buses. [60] [64] In recent years, costs have been reduced to levels comparable with diesel buses. [66] A variety of bus manufacturers are currently producing hydrogen fuel cell buses.
Hydrogen can be deployed as a fuel in two distinct ways: in fuel cells which produce electricity, and via combustion to generate heat. [58] When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapor. [58] Combustion of hydrogen can lead to the thermal formation of harmful nitrogen oxides emissions. [58]
At an electricity cost of $0.06/kWh, as set out in the Department of Energy hydrogen production targets for 2015, [73] the hydrogen cost is $3/kg. The US DOE target price for hydrogen in 2020 is $2.30/kg, requiring an electricity cost of $0.037/kWh, which is achievable given recent PPA tenders for wind and solar in many regions. [74]
Run through a fuel cell, the hydrogen immediately gives back that energy, in the form of electricity, as soon as it combines with oxygen. Out of the exhaust pipe comes only water vapor (H2O ...
Theoretically, there will be enough emissions-free energy sources in the future to supply fuel cell vehicles, and the cost of making the hydrogen plants and building now-expensive fuel cells will ...
The alkaline fuel cell (AFC) or hydrogen-oxygen fuel cell was designed and first demonstrated publicly by Francis Thomas Bacon in 1959. It was used as a primary source of electrical energy in the Apollo space program. [41] The cell consists of two porous carbon electrodes impregnated with a suitable catalyst such as Pt, Ag, CoO, etc.
