Industrial policy and business model of biomass energy coupled power generation as an important part of renewable energy, biomass energy has the characteristics of renewable, low pollution and wide distribution, which can significantly improve the environment, economy and energy security. In recent years, in order to deal with the problems of energy shortage and environmental pollution, all countries are vigorously developing and utilizing biomass energy, which will make biomass energy play an important and positive role in the field of energy substitution in the future. At present, the development of biomass energy in China mainly focuses on power generation, biogas, biomass briquette fuel and biological liquid. Among them, biomass power generation can be mainly divided into three forms: biomass direct combustion power generation (straw and garbage), biomass gasification power generation (including biogas) and biomass coupling power generation. In the following, based on the overall status of biomass power generation, the industrial policies and business models of biomass coupled power generation, especially coal-fired and biomass coupled power generation, are discussed and analyzed

analysis on industrial policy of biomass energy coupled power generation

at present, China's biomass power generation is still in the initial stage of development. Compared with direct combustion power generation and gasification power generation, the development of biomass coupled power generation lags behind. With the accelerating pace of global low-carbon development and the increasing environmental constraints, as an important means of energy structure adjustment and energy conservation and emission reduction, biomass coupled power generation has gradually attracted wide attention. Coal fired and biomass coupled power generation has become a key development direction, and effectively promoted the transformation and upgrading of coal-fired power. Since the use of another end hole in 2016, the state has issued a series of industrial policies to promote the development of coal-fired and biomass coupled power generation, indicating the direction for the comprehensive utilization of biomass energy (see table)

table main national industrial policies for coal-fired and biomass energy coupled power generation

under the guidance of national macro policies, local governments have also issued corresponding industrial policies. In addition, Ningxia, Guangdong and other places have actively carried out demonstration projects such as coal-fired and biomass gasification coupled power generation, coal-fired and sludge coupled power generation, and coal grinding and biomass coupled power generation. For example, the coal-fired and sludge coupled power generation demonstration project of Guangzhou CR thermal power, and the coal-fired and biomass gasification coupled power generation demonstration project of Ningxia Lingwu power plant of Huadian, etc

as mentioned above, the industrial policy of biomass coupled power generation continues the policy idea of "biomass energy" (4) evaluate the environmental feasibility of project construction energy agriculture environment ", which is mainly to reduce environmental pollution and increase farmers' income by making full use of agricultural and forestry resources. For example, the comprehensive utilization of agricultural and forestry wastes such as straw to produce engine exhaust purification materials for comprehensive utilization. At the same time, the coal-fired coupling power generation has played an important and positive role in reducing coal consumption, promoting the adjustment of energy structure and energy conservation and emission reduction. It has not only eased the pressure of carbon emission reduction for coal-fired power enterprises, but also broadened the development space for enterprises, brought new profit growth points, and effectively promoted the transformation and upgrading of coal-fired power

but on the whole, there are still many problems, mainly including the following points:

first, the lack of scientific and reasonable planning and layout. As an innovative power generation mode, coal-fired and biomass coupled power generation is still in its infancy, and the national and local governments have failed to incorporate it into the planning and make a reasonable layout

second, there is a lack of sound support policies. Although the policy guidance for supporting coal-fired and biomass coupled power generation is relatively clear, and the pilot project construction has been actively carried out, the relevant supporting policies and measures are not perfect, and there is no clear policy support in terms of electricity price, electricity, finance, taxation and funds. For example, the electricity price still continues the preferential policy of renewable energy, and the electricity quantity is only inclined to a certain extent

third, there is a lack of a sound regulatory mechanism. There is a lack of effective guarantee and supervision measures in the measurement of biomass CO combustion and the monitoring and measurement of biomass electricity. For example, most biomass coupled power generation projects use coal for power generation

analysis on the operation mode of biomass coupled power generation

in order to cope with the complex and changeable power situation and improve the competitiveness and operating efficiency, in the operation of biomass coupled power generation, each power enterprise must establish a practical operation and management mode in combination with its own characteristics. As mentioned above, coal-fired and biomass coupled power generation can be mainly divided into direct CO combustion and gasification CO combustion. Generally, pulverized coal boilers are used, and some circulating fluidized bed boilers are used. Due to the different input of different coupling methods. For example, the direct mixed combustion technology of straw is simple and feasible, which can directly use the coal-fired power units in service without a large amount of capital investment; Gasification and mixed combustion have higher requirements for the unit

therefore, the decisive factor is the selected coupling mode (type of coal-fired power unit), followed by technology, personnel allocation, fuel source, etc

each power enterprise shall choose different operation and management modes according to its own actual situation and local conditions. At the initial stage, the following three modes can be selected according to different coupling modes:

sole proprietorship mode. In the case of direct mixed combustion, due to the low requirements for units and technology, the active high-efficiency pulverized coal boilers and circulating fluidized bed boilers can be fully utilized to actively carry out coal-fired and biomass energy coupling power generation in the mode of sole proprietorship. For example, in December2005, the country's first "pulverized coal straw" mixed combustion generator set was completed and put into operation in Huadian International Shiliquan Power Plant, which adopted the mode of sole proprietorship and was 100% controlled by Huadian International Power Co., Ltd

strategic cooperative business model. If the gasification and mixed combustion mode is adopted, the unit and technology will become the main constraints on the selection of the business model. The allocation of gasification devices, the transformation of active boilers, etc. will expand the investment scale of the enterprise and face certain investment risks. Especially in the case that the relevant policies and measures for coal-fired and biomass energy coupled power generation are still imperfect, it is recommended that the enterprise adopt the business model of strategic cooperation by means of equity participation or holding, Actively and steadily carry out relevant project construction. On the one hand, it can reasonably control the investment scale and reduce the investment risk; On the other hand, it is conducive to the accumulation of enterprise technology, management and operation experience, and lays a solid foundation for future business expansion

the scope of consumer goods market has reached £ 1.03 billion PPP mode. This mode is mainly applicable to the coupling power generation of coal, garbage and sludge. As garbage and sludge treatment belong to the category of public utilities, the PPP mode of cooperation with public government departments is widely adopted. For example, CLP environmental protection won the bid for the Xuzhou sludge coupled power generation PPP project. In addition, several sludge coupled power generation PPP agreements were signed in Zhumadian, Henan, Nanjing, Zhenjiang, Wuxi, Jiangyin, Jiangsu and other places

to sum up, in order to realize the transformation and upgrading of China's energy development and achieve the goal that the proportion of non fossil energy power generation will not be less than 50% by 2030, it will be an inevitable choice to vigorously develop coal-fired biomass coupled power generation. Considering the fact that coal-fired power units play a dominant role in the power structure, coal-fired biomass coupled power generation is a powerful measure to optimize the allocation of energy resources, solve the problem of pollution control, promote the construction of ecological civilization and promote the green development of economy and society
