Ethanol able to meet third of global gasoline demand by 2050: IEA
London (Platts)--26May2005
Global ethanol production from mostly sugar cane has the potential to replace a third of the world's gasoline demand by 2050 if cane producers such as Brazil plan a rapid increase in their crops, according to a study by the International Energy Agency. Speaking to a refining conference in Brussels this week, IEA's transport energy specialist Lew Fulton said, under a "maximum expansion" scenario, ethanol could become a leading alterative transport fuel in the medium term, offering better CO2 saving properties than biodiesel. Citing figures from the UN's Food and Agriculture Organization, Felton said sufficient under-used agricultural land exists for a rapid expansion in sugar cane crops in warm counties, even taking into account the need for food crops. The scenario assumes a 5-10%/yr increase in cane planting levels with Brazil leading the way. Brazil, currently the world leader in ethanol production from cane, would provide 40% of the world ethanol under the scenario making it "the Saudi Arabia of ethanol," Felton said. The environmental benefits of ethanol would be even greater when sourced from cellulosic crops such as wood and grass or from cellulose waste in the longer term, he said. Ethanol can be currently blended to at least 10% in vehicles in OECD countries and is already blended up to 25% in Brazil. But outside Brazil, ethanol is mostly converted as a feedstock for the gasoline oxygenate ethyl tertiary butyl ether and most refiners are not keen on directly blending ethanol into gasoline. Felton said the IEA has extrapolated a recent upswing in global ethanol production helped by growing output from corn and seed-based sources in the US and Canada. He said, at current levels, the IEA believes ethanol's share of the global gasoline market could reach around 6%, or 120-bil liters, by 2020. "It would take a very ambitious ramping up, and very ambitious policies around the world, but that is the recent trend that we've gone on and its unclear if that's going to continue right now," Felton said. Fulton's scenario drew criticism from some conference participants, however, who claimed the higher costs of producing ethanol would hamper its uptake and said doubts exist over the availability of agricultural lands as world food demand continues to grow. Others pointed out that, as energy is consumed during the manufacture of ethanol, it can provide only marginal net C02 emission savings over standard gasoline when blending up to 10%. A shift in dependence to Brazil for 40% of the world's ethanol production would also be a setback for policies attempting to diversify global energy sources, some participants said. The Paris-based IEA, which represents the world's leading oil consuming nations, has said a 20% biofuels share worldwide is possible for 2030 with global bioethanol production seen growing by 2.3% a year to 2020.
