[HC pump network news] since February international oil prices continue to uplift, but China's crude oil imports continued peatlands. The foreign trade dependence degree has reached 60%. Experts said that China's oil supply and demand gap is still large, we must take precautions to pay close attention to alternative energy, including biomass energy development potential is worth further mining.
General Administration of Customs released the latest data show that from January to April this year, China's crude oil imports grew by 11.8%. Although the current international oil prices are still at a relatively low level, but compared with the beginning of the 12 year low, has rebounded more than 70%. Compared with the import price in April, China's crude oil imports in February rose 14.6% per ton.
Experts believe that biomass energy as a renewable energy, can be widely used in the field of transport, to make up for the domestic oil shortage, the potential is worth further mining.
Jiangsu joint sea Bio Technology Co., Ltd. chief economist Hu Haifeng said, compared with ordinary gasoline, ethanol gasoline can be reduced by about 40% PM2.5, hydrocarbon concentrations decreased by 42.7%, carbon monoxide emissions decreased by 34.8%. Since 2000, China's total consumption of about 17000000 tons of bio fuel ethanol, equivalent to about 90000000 tons of crude oil imports to reduce. Among them, in 2015 the domestic combustion of ethanol consumption was 2 million 300 thousand tons, adding fuel ethanol ethanol gasoline (E10) consumption of 22 million tons, accounting for 1.13 of the total national gasoline consumption of 19.5% tons of weight.
In fact, the development of biomass energy in the early stage of carrying with the grain for the land and the people for food yoke, so much controversy. But in recent years, under the guidance of the national fiscal policy adjustment, China's fuel ethanol industry gradually to the non food crops and cellulose raw materials comprehensive utilization of the direction of change, and actively carry out the construction process and demonstration projects.
Internationally, the government has vigorously promoted the development of fuel ethanol has developed into a worldwide emerging renewable energy industry. More than and 50 countries have developed a bio fuel supporting policies, including the provision of mixed indicators or instructions, to give tax incentives. These are the consideration of energy security strategy, sustainable development of agriculture and the promotion of rural economy, reduction of greenhouse gas emissions and mitigation of environmental pollution.
Fujian agriculture and Forestry University, director of the research center of energy plants, Dr. student tutor Jian Ming Qi in Shanghai to attend the "ECF biomass energy seminar 2016" introduced, the first generation of fuel ethanol with corn, wheat, Chen Hua grain starch conversion, and sweetener crop of sugarcane, sugar beet ethanol conversion. The second generation of fuel ethanol by plant straw cellulose, hemicellulose, lignin conversion of sugar and then converted to ethanol. The third generation of fuel ethanol feedstock selection is with high efficiency, high assimilation rate, high yield, anti inverse full-thickness usable of sweet sorghum (Sorghum bicolor), kenaf, bamboo and so on.
Shanghai joint non conventional energy research center of biomass energy experts, Shanghai Zhongwei Biochemical Co., Ltd. chairman Zhang Shichu and saline alkalization, desertification and degradation land after hemp kind crop cultivation and management and improvement, access to relevant state funding. Hemp crops per acre per year will absorb 2 tons of carbon dioxide, can be applied to clean development and carbon trading policy.
After decades of rapid development, biomass in the world's primary energy supply structure has reached about 10%, becoming the fourth largest source of energy. But in the beginning of China's biomass energy, the proportion is still small in the primary energy supply structure. EU biomass energy in the proportion of renewable energy as high as 60%, while China's biomass energy accounted for less than 10% of the proportion of renewable energy.
"Our country can be used as biomass energy resources, the total amount of about 4.6 tons of standard coal per year, the current has been used only 22 million tons of standard coal." Shanghai low carbon technology and Industrial Development Association Committee of experts, consultants, Shanghai Academy of Social Sciences researcher Xiao Jiang Wu introduced during the "Twelfth Five Year" period, the development of biomass energy in China the unfinished planning index, biomass briquette fuel consumption of only 70% of the planning, liquid biomass fuel only planning 50%.
Wu Xiaojiang said that China as a large agricultural country, produce more than 7 tons of straw resources each year, more than tons. But every year in the burning of straw about 3 tons, resulting in air pollution contribution rate of more than 30%. If the promotion of biomass fast pyrolysis for preparing liquid fuel technology, the rich straw resources into a huge amount of biological oil oilfield. In addition, our country agriculture and animal husbandry produced a large amount of organic waste and urban large quantities of biomass waste, a gas rich in resources, the use of biogas refining clean biomass gas purification is to alleviate the shortage of mineral deposits of natural gas resources in China.
Compared with the solar energy and wind energy, biomass energy has the characteristics of low cost storage, and more stable and sustainable energy supply. From the evaluation of the economic value of energy, biomass solid molding fuel calorific value is high, the use cost is much lower than the oil. In addition, the liquid biomass fuel is compatible with the automobile and gas station, which is economical and convenient. It can avoid the problems of insufficient charging facilities and battery energy storage capacity in the promotion of electric vehicles.
However, Xiamen University, director of the China Center for energy economics research linbojiang said that the biomass energy in China is still "niche" and do not form scale advantage. At present, the international oil price is at a low level. If the tax factor is not considered, the economic advantage of biomass energy is not obvious compared with that of ordinary gasoline. Therefore, the biomass energy industry still need to further speed up the cultivation, the formation of scale advantages, improve its economy.
