Opportunities and challenges of bio-gas industry under the background of "dual carbon"

According to the "Double Carbon Development Report of China Biogas Industry" released by the China Biogas Society, the current agricultural waste, urban organic waste and industrial wastewater resources that can be used for biogas production are 4.27 billion tons, 360 million tons and 6.54 billion tons respectively, all of which are used for the efficient production of biogas, and the maximum potential of biogas production is 540 billion cubic meters. It can realize the emission reduction potential of 960 million tons of carbon dioxide equivalent, and the emission reduction potential is huge. Taking into account the state of economic development and technological development.

4. Opportunities and challenges in the biogas industry under the dual-carbon wave

It provides a new platform for the development of biological gas engineering

With the formulation of the "double carbon" goal, the energy structure will be further optimized, the proportion of clean energy consumption will steadily increase, new energy and energy conservation projects will usher in new development opportunities, and build a broad development platform for the biological gas project, the implementation of the national "double carbon" strategy and the future demand for regional emission reduction will jointly promote the development of the biological gas industry

The reduction of waste at source was further improved

As an important treatment measure for the disposal of agricultural waste, industrial wastewater and urban organic solid waste, the bio-natural gas project will accelerate the reduction of waste sources, provide strong support for the implementation of strict ecological environmental protection policies by the state, and help the orderly progress of ecological civilization construction.

Functional complementarity promotes the integrated development of regional energy

At present, in order to achieve the goal of "double carbon", renewable energy such as wind power, photovoltaic, hydropower and other renewable energy has been greatly developed, but it is limited to differences in geographical and natural conditions, which cannot cover all needs. The bio-gas project has a certain degree of flexibility, enabling regional multi-energy complementarity, and effectively improving the level of energy clean development in rural and remote areas.

Biogas engineering still needs further development

At present, the state has supported the construction of 64 large-scale biogas projects and more than 1,400 large-scale biogas projects, but it still needs considerable development due to the influence of many factors such as the stable collection of raw materials, the effective disposal of biogas residue and biogas slurry, and the requirements of regional natural gas pipeline network connection. At the same time, in order to solve the fundamental problem of regional energy coordinated development, it is necessary to break the inherent thinking, form a system solution under the new situation, further play the advantages of biological gas engineering, and contribute to the promotion of regional energy clean and low-carbon development.

5, some domestic biological gas projects

Liangjiahe biogas project

Project scale: Daily treatment of livestock and poultry manure 5-6 tons, daily production of biogas 200 cubic meters, annual production of 100 tons of biogas residue, 1,500 tons of biogas slurry, annual emission reduction of greenhouse gases 800 tons of carbon dioxide equivalent.

CGN Hebei Hengshui bio-natural gas project

Project scale: The project can handle 150,000 tons of corn stalk, 150,000 tons of livestock manure and 160,000 tons of wine lees per year. The Hengshui project can produce 33 million m3 of biological natural gas per year and 200,000 tons of solid and liquid biological organic fertilizer. The produced natural gas can replace 42,000 tons of standard coal per year and reduce carbon dioxide emissions by 320,000 tons.

Shandong Minhe chicken manure biogas project

Project scale: Daily treatment of 300 tons of chicken manure, washing of 300 tons of chicken house sewage, and daily production of 30,000 cubic meters of methane.
