PetroChina plans to develop second-generation biofuels
Despite the Chinese government's call to diversify away from grain crops for the production of ethanol (earlier post), several biofuel producers stick to using corn and wheat. Others are focusing on using low value, non-food crops such as cassava and sweet potatoes. Together with the State Forestry Administration, China's largest oil producer PetroChina goes a step further and plans to produce second-generation biofuels, made from ligno-cellulosic low-input feedstocks such as woodchips and straw.
The energy firm did not say how much the deal was worth, but by 2010, it hopes to have capacity to produce over 2 million tonnes of non-grain based ethanol a year, it said in a statement. PetroChina hopes to become a leader in the biofuels field, and also plans a 200,000 tonne per year plant for the production of synthetic biodiesel derived from bio-oil obtained from the pyrolysis of forestry waste biomass, the statement added.
Dedicated energy farms
In addition, the State Forestry Administration and PetroChina will jointly set up 40,000-hectare energy farms in the southwest, growing plants that can be used as biomass feedstocks. It was not disclosed which energy crops will be cultivated, but it is reasonable to assume that they will not be grain crops (most likely, they will be plantations of fast-growing short-rotation coppice trees or grass species). The farms will eventually be able to provide the raw materials for the 60,000 tons of synthetic biodiesel the country's largest oil and natural gas firm aims to produce.
Jia Zhibang, director of the administration, says that the energy farms, to be planted this year, are located in the provinces of Yunnan and Sichuan, adding that the provinces of Hainan and Guizhou are two other ideal locations for growing energy crops:
ethanol :: biodiesel :: biomass :: bioenergy :: biofuels :: energy :: sustainability :: cellulosic ethanol :: biomass-to-liquids :: pyrolysis :: bio-oil :: Fischer-Tropsch :: China ::
"The resource is highly renewable, it doesn't compete for space with the forestry industry, it doesn't compete with humans for grains, and both the environment and the company can benefit at the same time," the statement said.
A growing appetite for bioethanol, driven by high energy prices and worries about energy security and global warming, has recently helped push up grain prices worldwide. Food security concerns and a shortage of arable land are likely to limit the amount of ethanol that can be made from grains even as demand grows, but cellulosic ethanol could make larger-scale substitution for gasoline viable.
