Hydrogen fuel cell bus. Gas cylinders on the top of the bus provide hydrogen to the fuel cells. There, the hydrogen and oxygen react to form water and electrical power. This is a cleaner source of power than the burning of fossil fuels to form carbon dioxide and other pollutant gases. Following a trial that lasted from 2004 to 2007, this route (RV1) has now been converted permanently to include eight hydrogen buses. Photographed in London, UK.
