Petrochemical resources are limited and are bound to be scarce in the times to come. Also, due to their adverse impact on the environment, which has lead to a widely discussed phenomenon of global warming, the use of these fossil fuels has to be reduced by both the developed as well as the developing world.

Development of CO2-neutral sustainable fuels thus becomes a high priority in the research regimes across the world. Energy generation from certain plants like rape or oil palm may not be the best option as these may also be used for food production. Thus Hydrogen, which is used by fuel cells to generate electricity, could be a likely winner due to absence of green house gas generation in fuel cell technologies.
