The biodiesel dream

Thread Content

Is biodiesel merely a temporary substitute in an era of high oil prices, or is it one of the long-term options for renewable energy in China? 　　Few people predicted that oil prices would soar to such extreme levels in 2007: on November 7, the price of crude oil futures for delivery in December on the New York Mercantile Exchange briefly exceeded $98 per barrel ； Although it declined slightly at the close, breaking through the three-digit mark has become a real possibility. 　　China’s retail fuel prices are also being raised quietly. **The National Development and Reform Commission issued a notice stating that the prices of gasoline, diesel, and aviation kerosene will each increase by 500 yuan per ton starting from 0:00 on November 1. As soon as the news came out, airline fuel surcharges rose immediately. 　　However, high oil prices do not always mean bad news, especially for emerging alternatives to traditional energy sources such as the biodiesel industry. 　　From October 29 to 31, in Haikou City, Hainan Province, an international conference organized by the UNDP Office in China, the Energy Research Institute of the National Development and Reform Commission, the Chinese Society for Renewable Energy, and the Green Energy for Poverty Reduction Project attracted over 300 participants, including experts, scholars, and business professionals from more than 20 countries. 　　The focus of the conference was Jatropha, an energy crop that can be used to produce biodiesel. 　　Since the end of 2006, when the **Commission for Development and Reform halted new projects for producing fuel ethanol from grain, many investors and even policy makers turned their attention to producing bioethanol and biodiesel from non-grain crops. 　　The crazy “jatropha” tree – commonly known as the jatropha tree, it is a tropical plant whose seeds contain 30% to 60% oil. 　　This tree can grow on dry and infertile land or barren mountains, without requiring forest or farmland; moreover, it has a high yield, with a productive period of 20 to 30 years, making its cost relatively low. This plant, known in the industry as the “diesel tree,” naturally becomes one of the key players in the new wave of “biodiesel dreams.” 　　The Jatropha tree is native to Latin America, but Chen Fang, dean of the School of Life Sciences at Sichuan University, told a reporter from Caijing that China is one of the first countries in the world to conduct systematic research on Jatropha. 　　Institutions such as Sichuan University, the Sichuan Provincial Forestry Science Research Institute, and the forestry research institutes in Yunnan Province began conducting research on and cultivation of Jatropha trees from an energy development perspective as early as over 20 years ago. 　　Regrettably, given the circumstances at the time, this industry did not receive attention from investors nor from **decision-makers. It was not until recent years, after countries such as India, Indonesia, and Malaysia achieved success with jatropha biodiesel, that a new wave of interest emerged in China. 　　In 2005, the Sichuan Yangtze River Afforestation Bureau, in collaboration with Sichuan University and the Sichuan Academy of Forestry Sciences, conducted research to develop two superior Jatropha varieties, namely “Gaoyou 1” and “Gaodu 1”, and established demonstration sites for the propagation and cultivation of these new varieties. 　　In the same year, a pilot plant capable of producing 200 tons per year of jatropha biodiesel blended fuel was also established, which manufactured B-15 blended diesel (comprising 15% vegetable oil mixed with 85% diesel), and this blend successfully passed 15,000 kilometers of diesel engine testing. The B-20 jatropha biodiesel synthesized using microemulsion composite additives was also successfully tested in diesel buses operated by the Chengdu Public Transportation Company. 　　Apart from Sichuan, other regions with natural conditions suitable for growing this plant, such as Yunnan, Hainan, and Guizhou, have also initiated small-scale cultivation and oil extraction activities under the guidance of research institutions. 　　More importantly, since 2006, a wave of industrialization has been coming one after another. 　　Currently, the American company BECOO and the British SunTech Group are investing in Sichuan Province’s Panzhihua City and Yunnan Province’s Honghe Prefecture to establish Jatropha planting bases. 　　Beck Company has even set ambitious goals, intending to invest between $1.6 billion and $2 billion over the next decade in building the world’s largest biodiesel feedstock cultivation base in Panzhihua, which will include 200,000 hectares of jatropha plantations as well as a biodiesel refinery with a capacity of 400,000 tons per year. 　　Subsequently, the three major domestic oil giants also quickly followed suit. Among them, PetroChina (**exchange code: 0857, Shanghai Stock Exchange code: 601857**) plans to build a pilot project for the production of 10,000 tons of biodiesel at its Nanchong refinery, with completion of this project expected by the end of 2007. At the same time, the company also plans to invest in Yunnan and Sichuan over three years to establish jatropha plantations covering a total area of 1 million mu. 　　In addition to its intention to acquire an Indonesian biofuel project together with two other investors for $5.5 billion, China National Offshore Oil Corporation has also signed a \"Jinshui Region Jatropha Biodiesel Industry Development Project\" agreement with Panzhihua City. The planned investment for this project is 2.347 billion yuan; by 2010, it is expected to establish a planting base of 500,000 mu for Jatropha trees, as well as a biodiesel refining facility with an annual production capacity of 100,000 tons. 　　In addition, Sinopec has also decided to build a biodiesel refinery with an annual production capacity of 100,000 tons in Panzhihua, along with a cultivation area of 400,000 to 500,000 mu for Jatropha trees to support it. 　　According to reporters from Caijing, many large, financially strong enterprises in the southern provinces have also established subsidiaries for energy development in an attempt to enter this \"green gold\" industry. On October 29, at the opening ceremony of this “International Symposium on the Development of Jatropha Industry” held in Hainan, reporters noticed that many people from the United States, South Korea, Singapore, as well as domestic conglomerates were asking around and seeking partners. 　　Encouraged by the surge of investor interest, almost all provinces suitable for the cultivation of this tropical crop have formulated ambitious plans. 　　For example, Yunnan Province has set a goal of establishing 10 million mu of Jatropha plant cultivation areas over the next decade, in order to produce 1 million tons of biodiesel annually ； In Sichuan Province, only Panzhihua City has set the goal of establishing a raw material base for Jatropha trees covering 3 million mu within five years, as well as raw material processing plants. Within ten years, by expanding the scale of cultivation and encouraging development in surrounding areas, the target is to reach a cultivation area of 8 to 10 million mu, with Panzhihua becoming a **key bioenergy industry hub**. 　　In addition to the industry and local authorities, international organizations are also interested in the Jatropha trees. 　　In November 2006, the United Nations Development Programme, together with the Ministry of Science and Technology and the China International Economic and Technical Exchange Center under the Ministry of Commerce, launched the “China Green Poverty Alleviation” project. This project, with a total budget of $8.585 million, aims to increase the income of farmers living in the border area of Sichuan, Guizhou, and Yunnan provinces by helping them grow Jatropha trees, from which biodiesel can be produced, thereby improving both their earnings and the local fragile ecosystem. 　　 　　Biodiesel route The production of biodiesel in China initially started from vegetable oil residues and swill oil. Currently, Sichuan Gushan Oil Chemistry Company and Fujian Zhuoyue New Energy Development Co., Ltd., which entered this market in 2002 and 2003 respectively, already possess the capacity to produce 30,000 tons and 100,000 tons of biodiesel per year. 　　Low cost and the ability to be used directly in diesel engines are the advantages of this type of biodiesel. However, a shortage of raw material supply has always been the main factor restricting the development of the two companies. 　　It is reported that the current market price of such biofuels before blending for biodiesel is around 3,500 yuan per ton, while the latest wholesale price of regular diesel has already exceeded 6,000 yuan per ton. 　　It was after 2005 that biodiesel moved from the research and development stage to large-scale industrial production. At a time when fuel ethanol was in high demand, biodiesel did not receive much attention. 　　However, in March 2006, the \"11th Five-Year Plan for Economic and Social Development of the People’s Republic of China\" explicitly proposed for the first time to \"expand the production capacity of solid biomass fuels, fuel ethanol, and biodiesel.\" 　　Apart from the Jatropha tree, China’s academic and business communities also once held high hopes for biodiesel made from rapeseed. An expert from the Chinese Academy of Agricultural Sciences once said that if developed properly, China’s rapeseed \"could potentially replace 1.5 Daqing oil fields.\" 　　Around 2006, many places such as Hunan and Jiangsu saw a surge in interest in launching projects to produce biodiesel from rapeseed. 　　However, these projects do not conform to China’s overarching principle regarding biofuel development, which is to \"not compete with food for grain, nor compete with grain for land,\" and as a result, they faced the same fate as fuel ethanol made from grains. The executive meeting of the State Council held on September 19, 2007, explicitly stated that China would impose strict controls on projects for converting rapeseed into biodiesel. 　　In addition, Zanthoxylum trees, Phellodendron trees, tung trees, and Sapium sebiferum have also successively become preferred candidates for the development of the biodiesel industry. 　　However, taking into account factors such as raw material supply, cost, and oil content, the general view is that Jatropha trees still hold a significant advantage. Jatropha trees can adapt to various barren mountains and wastelands, producing 160 kilograms to 180 kilograms of biodiesel per mu per year. 　　Industry experts told reporters from Caijing that, with technological advancements, there is still room for further increases in oil production. 　　In many parts of China, Jatropha trees began to be planted on a large scale only after 2005. These trees are still in their growth phase, and it will take at least three years before biodiesel derived from them can be used in the market. However, based on the estimated selling price of jatropha oil at around 4,000 yuan per ton, it still holds a certain price advantage over regular diesel on the market, unless international oil prices drop significantly by then. 　　According to reporters from Caijing, the area of Jatropha plantations under construction in China currently amounts to around 600,000 to 700,000 mu ； However, the rules in various regions and the bases planned to be built amount to as much as 30 million mu ； The capacity for biodiesel production that is under construction or in the design phase, including projects related to Sichuan pepper oil and used cooking oil, has also exceeded 10 million tons. 　　 　　Between Heat and Cold On September 4, the **National Development and Reform Commission released the ‘Medium- and Long-Term Development Plan for Renewable Energy’ (hereinafter referred to as the plan)**. The plan states that by 2010, the annual consumption of biodiesel will reach 200,000 tons ； In 2020, the annual consumption of biodiesel is set to reach another 2 million tons. 　　An expert who wished to remain anonymous criticized this plan in an interview with a reporter from Caijing, stating that it was \"too conservative\". Because according to this goal, by 2020, the replacement rate of biodiesel for conventional diesel in China was still less than 1%. 　　However, on a global scale, as an emerging energy industry that is still in its infancy, the development of biodiesel varies from place to place. 　　In regions where there are no food security issues, high energy consumption, and relatively developed economies, biodiesel has become the fastest-growing alternative energy source. 　　In Europe, biodiesel already accounts for over 5% of the refined oil market ； According to the targets set by the European Council, the share of bioalternative fuels was to reach 5.57% by 2010, and around 20% by 2020. Among them, Germany has required that 5% biodiesel be added to petroleum diesel since January 1, 2004. 　　According to projections by the U.S. **Biodiesel Board, by 2015, U.S. biodiesel production capacity could reach 18.5 billion gallons per year, which would equate to a replacement of 5% of the traditional diesel used in the United States each year. Countries such as France, Italy, and Japan now have an annual biodiesel production volume of nearly 1 million tons each ； Switzerland, on the other hand, claims it will plant 100,000 hectares of biodiesel crops in order to address about 50% of its annual oil supply needs. 　　However, it is worth noting that the **raw materials used for producing biodiesel remain mainly corn, soybeans, canola, and palm – oil crops that are superior to Jatropha trees. 　　Therefore, for China, which is unable to replicate this model at all, there is no existing framework to determine how fast it can progress in the field of biodiesel. 　　**Ren Dongming, deputy director of the Energy Research Institute of the National Development and Reform Commission, said in an interview with a reporter from Caijing that the development goals set out in the plan were not due to conservatism, but rather the result of careful consideration. 　　Not to mention the excessive consumption of crops such as corn and soybeans, which can cause huge fluctuations in food market prices, even taking Germany’s use of rapeseed to produce biodiesel as an example, large-scale cultivation of such crops can damage biodiversity; excessive fertilization, over time, can also harm the soil environment. 　　In Ren Dongming’s view, the supply of raw materials remains one of the main factors restricting the development of biodiesel in China. “Currently, the cultivation of energy plants is generally on a small scale and in a scattered manner, making it difficult to meet production requirements. ”He told a Caijing reporter. 　　According to reporters from Caijing, the plans to establish Jatropha planting bases across various regions, with a total area of around 30 million mu, also involve a degree of rash decision-making. 　　“From the highest levels down to the local level, no one has yet had the time to fully understand the situation of these lands. ”Chen Fang, dean of the School of Life Sciences at Sichuan University, raised such criticism in an interview with a reporter from Caijing. 　　Critics also point out that many provinces launched new energy projects on a large scale without prior scientific demonstration or industrial support, following a typical \"Great Leap Forward\" approach. 　　After years of continuous afforestation and forest conservation efforts, the total area of barren mountains and wastelands in China has been decreasing. How can the target of 30 million mu be achieved? Will it come at the cost of cutting down some forest land, or making extensive use of abandoned land? All of these require further attention. 　　Chen Fang’s personal estimate is that at present, in China, there are only around 17 million mu of land truly suitable for the cultivation of Jatropha, and where it can be grown without competing with forests or crops for land use; this is far less than the planned total of 30 million mu. 　　On October 30, a reporter from Caijing visited a Jatropha planting site in Hainan and found that the 1,500 mu of land rented by local companies was labeled as barren mountain land, but in reality it was fertile farmland located near a reservoir – land that had been abandoned by local farmers who went to work elsewhere or chose not to engage in farming. It is reported that the company plans to plant 50,000 to 100,000 mu of Jatropha trees over the next two years; the land leased is of a similar type, with lease terms lasting up to 30 years. 　　“This approach **will absolutely not be supported.** ”Ren Dongming told a reporter from Caijing, “Even if the land is left uncultivated, it should not be encouraged to be used for growing energy crops.” ” In the view of some experts, once these agricultural lands are used for growing trees over a long period of time, it becomes very difficult to restore them to their original state. 　　For the biodiesel industry that uses plants such as Jatropha as raw materials, finding the right balance between promising prospects and various practical constraints in order to achieve true sustainable development remains a topic that requires continuous exploration
