We will promote diversified development of biomass energy

At the same time, biomass energy has advantages that renewable energy sources such as wind and solar power do not have. First, it can be converted into various forms of energy, which can supply power, heat, gas (biogas, biological natural gas, biological hydrogen, etc.), provide liquid fuel (bioethanol, biodiesel, aviation kerosene) and solid molding fuel. Second, it has the characteristics of natural carbon neutrality, the formation of biomass itself is a process of carbon fixation, so the development and utilization of biomass energy does not increase carbon dioxide in the atmosphere. Third, biomass power generation can become a stable power supply, the average annual power generation hours can reach more than 7,000 hours, much higher than the photovoltaic power generation of more than 1,000 hours and wind power of more than 2,000 hours, and biomass power generation than photovoltaic power generation and wind power is more stable, the future can replace coal power to a certain extent as a supporting power supply, providing base load for the power system.

Looking forward to the future, with the continuous promotion of the "dual carbon" strategy and the adjustment of the energy structure, China's biomass energy industry will enter a stage of high-quality development, and gradually form a diversified development pattern of electricity, heat, gas and liquid fuels. It plays an irreplaceable role in the treatment of agricultural and forestry waste and urban and rural organic waste, reducing urban and rural environmental pollution, promoting energy transformation, helping rural revitalization, and building a beautiful China.

The prospect of biogas is not to be underestimated

Li Jingming (Secretary General of China Biogas Society, first Chief expert of Agroecology and Resource Protection Station of Ministry of Agriculture and Rural Affairs) : According to the national standards issued by the State Administration of Market Supervision and Administration and the National Standardization Administration, biological natural gas is a combustible gas mainly containing methane produced by thermochemical conversion or biochemical conversion of biomass as raw materials, and a renewable natural gas mainly containing methane components produced by purification or methanation process. The combustible gases mentioned here mainly include biogas, biomass pyrolysis gas, landfill gas, etc., of which biogas is the most direct, easiest and most stable upstream product.

Biological gas has been developed in our country for many years. Since 2015, with the consent of The State Council, the National Development and Reform Commission and the Ministry of Agriculture and Rural Affairs have used the central budget funds for three consecutive years, with an annual investment of 2 billion yuan, to organize the rural biogas transformation and upgrading pilot demonstration projects nationwide, and have supported the construction of more than 1,400 large-scale biogas projects and 64 large-scale biogas pilot projects. In December 2016, the 14th meeting of the Central Financial and Economic Leading Group clearly put forward "two directions" for the treatment and resource utilization of livestock and poultry manure, that is, "biogas and biological gas are the main treatment direction, and on-site use of rural energy and agricultural organic fertilizers is the main use direction." 

In 2017, The General Office of the State Council issued the Opinions on Accelerating the Resource Utilization of Livestock and Poultry Breeding Waste, and in 2019, the National Development and Reform Commission and other departments jointly issued the Guiding Opinions on Promoting the Development of Bio-Natural gas Industrialization. In the demonstration projects promoted by the Ministry of Agriculture and Rural Affairs in the whole county, such as the resource utilization of livestock and poultry manure, the replacement of chemical fertilizers by organic fertilizers, and the comprehensive utilization of crop straw, biogas and biological gas are regarded as important technical means. Under the guidance of relevant national policies, leading enterprises in the industry have joined the ranks of investment, construction and operation and maintenance of biological gas projects.

In the process of construction and operation, all localities adhere to the construction of biological natural gas projects as an important starting point to promote the utilization of agricultural, rural and urban organic waste resources, the development of ecological circular agriculture, and the construction of beautiful villages, achieving good results, and accumulating some valuable and reproducable mature technology models and successful experience.

Introduce preferential policies. Relevant departments of finance, agriculture, environmental protection, land, taxation, electric power, finance and other localities strengthened coordination and cooperation, actively introduced supporting policies, and jointly promoted the construction and operation of the project. The People's Government of Dali City in Yunnan Province approved the construction of six bio-gas filling stations by Shunfeng Erhai Bio-Gas Company, and 200 bio-gas taxis have been put into operation.
