producing real,
carbon - free hydrogen
fuel.»
For this reason methanol
fuel cells will be used, where the combination of methanol and oxygen
produces water and
carbon dioxide as a waste product (note that the
carbon footprint in this case is neutral in that the methanol will be
produced by photosynthesis, removing CO2 from the atmosphere).
Combustion causes almost every atom of
carbon in the
fuel to combine with two atoms of oxygen,
producing carbon dioxide.
The 1997 Kyoto Conference — a world meeting on fossil -
fuel use —
produced an agreement by a handful of highly industrialized countries to reduce
