Biofuels for airlines promising, but hurdles remain

Biofuels could be used to fly commercial airlines within the next decade as a viable alternative to kerosene, although costs and concerns over environmental impact remain big barriers

Jatropha, a poisonous plant that produces seeds that can be refined into biofuels, is being touted as a good alternative fuel and a potentially powerful weapon against climate change.

Experts say the perennial plant can grow on marginal land with limited rainfall, and does not compete with other food crops or encourage deforestation.
