Biofuel increasingly competitive if oil surge lasts
Posted online: Thursday, June 23, 2005 at 0000 hours IST
PARIS, JUNE 22: Biofuels would be increasingly competitive if crude o
il prices, which are back near all-time highs, were to go beyond $60 a
barrel, officials at the International Energy Agency (IEA) said on Tuesday.
Soaring oil prices have encouraged major consumers worldwide to sharply
increase their use of ‘green’ biofuels, made from sugar cane, vegetable
or grain oils.
But in most parts of the world the additional costs for producing biofuels
make the fuel uncompetitive without hefty tax rebates from governments.
“Biofuels are getting more competitive due to the surge in oil prices but
these would need to be somewhere between $60 and $100 a barrel for biofuels
to be competitive without subsidies,” IEA biofuel specialist Lew Fulton
said after a seminar on biofuel options.
US crude oil futures hit another all-time record on Monday at $59.52 a
barrel as worries over fuel demand festered amid limited US refinery
capacity.
An exception is Brazil where ethanol, made from sugar cane, is competitive
without subsidy when oil prices are at $35 a barrel, said Brazil's
ambassador to Paris, Sergio Silva do Amaral.
The IEA renewed its estimate that all biofuels - ethanol and biodiesel -
had the potential to reach 10% of world fuel use for transport by 2025.
But Fulton said a more realistic estimate was that global ethanol
consumption should be between four and 5% of gasoline use by the end
of the decade. “That would be a very big achievement but a lot will
depend on oil prices,” he said.
Last year the world produced about 30 billion litres of fuel-ready
ethanol from fermenting and distilling mainly sugar or corn. In oil
terms, that’s more than 500,000 barrels per day (bpd), 2% of global
gasoline use.

: 不太理解到底實驗室跟應用到底有多大的差距?
: 希望大家一起討論一下
