2011 is turning into the year of sustainable jet fuel.
On 15 July, Lufthansa began flying between Hamburg and
Frankfurt using a 50/50 mix of traditional fuel and biomass fuel made from plants.
On 20 July Finnair went one step further, flying from
Helsinki to Amsterdam -- the longest route thus far -- using a 50/50 mix of jet
fuel and biofuel made from cooking oil retrieved from restaurants.
Dutch company SkyNRG, which supplied
the biofuel used to power Finnair’s Airbus engines, is
also supplying KLM with fuel for 200 Amsterdam-to-Paris
flights that start in September. Starting 28 July, low-cost airline Thomson
Airways will fly one biofuel flight a week, from Birmingham, England to Palma,
Spain. Even the 2050 conceptual
hypersonic plane that makers say will be able to travel
from Los Angeles to Tokyo in two-and-a-half hours at speeds of up to Mach 4
will be powered partly by biofuel.
With traditional jet fuel costing so much, both
wallet- and climate-wise, and with 1.5 to 1.7 billion barrels consumed annually
worldwide, it is not surprising that many airlines, including Virgin,
Continental and Japan Air, are looking into alternative fuel sources. British
Airways recently teamed up with Solena, an
American company that turns household, urban and agricultural waste into fuel. According
to SkyNRG, biofuels will be commercially viable for airlines to purchase when
they are just 1% of the total supply of all jet fuel, which could happen by
Biomass fuel is created from plant crops (like
sugarcane, hemp, even algae) and other types of waste like recycled cooking oil.
Critics argue that the eco-friendly fuel has its own carbon costs and takes
land away from planting edible crops. But Lufthansa
says the jatropha and camelina plants that make up their fuel would not have
been grown on land that is part of food production. And SkyNRG,
which claims to have a sustainable supply chain, from “feedstock to flight”,
argues that each “green route” makes this type of fuel more accessible and
