Biomass heating is expected to "heat up"



The reporter learned that since the end of 2016, the "coal to electricity" and "coal to gas" aimed at reducing coal burning and cleaning heating have kicked off. However, affected by the current economic capacity, technical feasibility, heating effect and other factors, the road of "coal to gas" and "coal to electricity" implementation is fraught with difficulties.

Some insiders pointed out that China's biomass energy has great development potential, the use of biomass energy heating "coal to produce" is a better choice to replace loose coal heating in rural areas. Today, as a more advantageous alternative to coal-fired heating in counties and rural areas, "coal to life" has begun to receive attention.

We will promote the extension of preferential policies to "convert coal into coal"

"In the next step, we will strengthen investigation and research to promote the extension of the preferential policy of 'coal to gas' and' coal to electricity 'to' coal to life ', and develop clean biomass heating according to local conditions," the National Energy Administration said in the "Reply".

According to statistics, at present, there are about 120 million tons of straw and 200 million tons of forestry residues that can be used for energy utilization in rural areas of China. Different from the environmental pollution caused by straw incineration, biomass resources can be used efficiently and cleanly as fuel, and can be used locally, which is both economical and environmentally friendly.

At the same time, the goal of "striving to peak carbon dioxide emissions before 2030 and striving to achieve carbon neutrality before 2060" means that energy conservation, emission reduction, development and utilization of clean energy will become the focus of China's development. "In this context, the '14th Five-Year Plan' and '15th Five-Year Plan' will definitely increase the 'coal control' efforts." Compared with "coal to gas" and "coal to electricity", the cost of biomass heating is closer to the cost of coal. Therefore, the scale of biomass clean heating will increase significantly during the '14th Five-Year Plan' period." Zhang Dayong, secretary general of the biomass energy industry branch of the China Industrial Development Promotion Association, said in an interview with reporters.

"A few years ago, the core reason why the" coal to electricity "and" coal to gas "can not be changed is that the cost is too high. After some areas changed from coal to electricity and coal to gas, people could not afford it, so they switched to burning coal again." Zhang Dayong revealed to reporters.

It is understood that the comprehensive Department of the National Energy Administration has issued the "Notice on Matters related to the preparation of the 14th Five-Year Plan for the development of renewable energy" (referred to as the "Notice") that priority is given to the development of local decentralized and distributed renewable energy resources, and vigorously promote the direct use of distributed renewable electricity, heat, gas, etc. in the user side, combined with new technologies such as energy storage and hydrogen energy. Increase the share of renewable energy in the regional energy supply.

A relevant person of China's rural energy industry Association told reporters that at this stage, the promotion of decentralized biomass energy heating in rural areas is in line with the principle of "adhering to local conditions and affordable for residents" in the relevant planning, and in line with the requirements of the Notice, which is a realistic choice to achieve clean heating in rural areas.

"During the 14th Five-Year Plan period, if the north, especially in rural areas, promotes clean heating in a large area, then biomass energy is definitely the first choice." Zhang Dayong said that if the preferential policy is extended to "coal to biomass", it will make a great contribution to the development of the entire biomass energy industry and carbon emission reduction in rural areas.

The construction of a collection and storage system for agricultural and forestry residues should be encouraged

Jiang Ximeng suggested encouraging the construction of a collection and storage system for agricultural and forestry residues such as straw; Encourage the development of biomass molding fuel industry, and implement tax relief for rural biomass molding fuel enterprises and related industry chain enterprises.

"Reply" said: "The next step, the Ministry of Agriculture and Rural Affairs will, in accordance with the relevant requirements, accelerate the support and cultivation of a number of straw fuel clean heating implementation of the main body, encourage the relevant bodies to establish a collection, storage and transportation system, supporting facilities and equipment, and constantly improve the level of development of straw fuel clean heating industrialization." The National Development and Reform Commission will continue to support the comprehensive utilization of straw through special funds for ecological civilization construction."

Zhang Dayong believes that it is very important to establish a business model for raw material collection and storage in rural areas. "If the national policy is extended to the village level, the biomass molding fuel processing point is established in the township, the people take firewood, pull there to process the molding fuel, and pay some processing fees. In this way, the cost of using biomass fuel is much cheaper than coal, and biomass energy will replace coal in rural areas, which will be a qualitative leap."

In previous years, the state has given certain subsidy support to molding fuel processing equipment and straw collection and storage. Zhang Dayong said that the future processing of biomass molding fuel if the use of agricultural electricity, will effectively reduce the cost of biomass fuel processing, but also conducive to rural areas, "coal", can allow more enterprises to focus on biomass molding fuel processing.

The reporter also noted that in terms of encouraging the development of biomass molding fuel, the "Reply" said that it would further study and adjust the scope of agricultural production electricity.

In this regard, Zhang Dayong suggested: "Biomass molding fuel processing, biomass clean heating, biomass natural gas should be included in the scope of rural electricity support." He believes that this can promote the implementation of energy revolution in rural China, change the production and acquisition methods, and promote the green low-carbon and circular development model of the main use of biomass energy.

Building energy efficiency is essential for clean heating in rural areas

Jiang Ximeng suggested: "We should actively implement the central government's policy of encouraging the development of agriculture-related and small and medium-sized enterprises, and include the thermal insulation transformation of rural buildings and biomass heating transformation in the financial service projects with the same preferential conditions as housing loans." In this regard, the "Reply" said that in the next step, the National Development and Reform Commission will cooperate with the financial management department to actively implement the central government's financial support policy on the development of agriculture-related, private and small and medium-sized enterprises.

Zhang Dayong believes that the national green finance policy should support the thermal insulation transformation of rural buildings and biomass heating transformation, and increase support in the implementation of the rural low-carbon energy strategy. "The scope of national green finance policy support should not be limited to 'coal to electricity' and 'coal to gas', and it is necessary to include building energy conservation and' coal to life 'in the support category." "He stressed.

Some experts have pointed out that through the energy-saving renovation of existing rural housing, to achieve the improvement of the energy efficiency level of rural housing buildings, reduce the operating costs of heating systems, fundamentally solve the coordinated development of the user side of the building and heating energy consumption demand, reduce the risk of "return coal", and form a long-term mechanism for the sustainable development of clean heating.

It is understood that the same area of rural buildings, urban buildings, heating energy consumption difference of 2-2.5 times. "Because the buildings are not warm and the air leakage is serious, the energy consumption in the countryside is higher." Zhang Dayong believes that reducing rural clean heating energy consumption is very important to promote clean heating in rural areas. "We are also doing this work, and have recently communicated with the World Bank and the Green Finance Center of Huaxia Bank, hoping that they can use more funds to support clean heating in rural areas, and at the same time, combine it with energy-saving renovation of rural buildings."

At the same time, in order to accelerate the promotion of distributed biomass heating in rural areas, the China Rural Energy Industry Association suggested to the National Energy Administration that the investigation and evaluation of rural biomass energy resources and the research and development of rural distributed biomass heating technology and equipment be included in the scope of clean heating "14th Five-Year Plan" and project support.
