The significance of distributed utilization of biomass

1.1 Distributed utilization is in line with the characteristics of biomass resources

Biomass resources from a variety of sources, low energy density, distribution of dispersed, these resource characteristics determine the local conditions, distributed utilization is the inevitable requirements for the development of biomass energy industry. In terms of resource supply, it should be developed and utilized locally, without the need for long-distance transportation, effectively reducing transportation costs, in line with the natural attributes of biomass resources with low density and decentralized distribution; in terms of energy use, it should be used in close proximity to the end-users, and the excess energy can be sent out; in terms of management and operation, it should be equipped with the ability and conditions to operate independently, and can be connected to the network or utilized in complementary phases with fossil fuels, if necessary.

Distributed biomass energy technology application scale is very flexible, according to the actual local situation to meet different needs, such as, can build a small power station, can also be used as a residential gas, or even as heating, industrial kiln fuel, etc., is the real realization of the biomass energy "according to local conditions," the development and utilization of an effective way. And from the industrialization point of view, due to the distributed biomass energy technology on the raw material type and scale adaptability, project scale requirements, low capital threshold requirements, high return on investment, the adaptability of a variety of user needs, different scales have a certain degree of economy, so the distributed use of biomass energy than centralized use of easier to commercialize. In general, distributed biomass energy technology is in line with the characteristics of China's scattered biomass resources, suitable for decentralized utilization and industrial applications, with strong adaptability and viability, the development of distributed biomass energy technology in China has a wide range of application prospects.

1.2 Distributed utilization of biomass energy is in line with China's current development situation

China's economic development is not balanced, and there are big differences in the structure of residential energy consumption. On the one hand, there are still about 133 million rural households using traditional biomass energy as the main cooking or heating energy, and many rural areas in the central and western parts of the country are still using straw, fuel wood and other directly burned traditional biomass energy sources as the main source of living energy; on the other hand, with the development of the rural economy in the eastern coastal areas and the improvement of the standard of living, the use of traditional biomass as a source of living energy has been greatly reduced, and a large number of Crop straws are abandoned in the fields and burned on the spot, and air pollution is very serious.

China is vigorously promoting new urbanization and new rural construction, which requires a large amount of clean energy supply. Making full use of abundant and cheap biomass resources in the rural areas and accelerating the development of biomass industry is an effective way to solve the problem of sustained supply of energy in rural areas in the future. Biomass energy, as clean energy derived from agricultural and forestry by-products, can provide living energy for rural urbanization, including heating, gas and electricity, forming a new supply mode of rural energy self-production and self-sale. Distributed biomass conversion technology is the most suitable industrialization direction for decentralized rural utilization, such as the use of sticky poles to provide rural areas with heat, electricity, gas and other sources of living energy, which is an effective measure for new rural areas to get rid of coal-fired whips.
