It is high time to vigorously develop bio-natural gas

However, there is still a huge gap between the amount of bio-natural gas development and the amount of resources in China. The reason is that the industry positioning is not clear, the competent department is not clear; The second is the lack of systematic policy design, it is difficult to get through the blocking points and difficulties in the industrial chain; Third, the mechanism of "who polluts who pays" in the breeding industry has not been implemented in place, resulting in difficult raw material collection and high cost; Fourth, the lack of effective market pulling mechanism and mature business model, the industry development is slow. The current gas management system barriers limit the marketization and promotion of biological gas, and the completed projects can not enter the city gas pipeline network, and it is difficult to achieve large-scale development. Fifth, the adjustment of agricultural planting structure is not in place, the market sales channels of biogas residue and biogas slurry are not smooth, especially the excessive antibiotic residues of poultry manure affect the return to the field; Sixth, there is still a gap with the international advanced level in low temperature fermentation, tank capacity gas production rate and automation level.

To realize the high quality development of biological gas is an effective measure to improve China's energy security and promote the green and low-carbon transformation of natural gas industry. At the same time, it is also an inherent requirement to promote the high-quality development of the aquaculture industry and improve the rural living environment, and an important starting point for implementing the rural revitalization strategy and promoting rural green development. At present, the price of LNG has risen, and the cost advantage of biological gas has been highlighted. In particular, the establishment of the domestic carbon market provides a platform for bio-gas to achieve green and low-carbon market-oriented value, and the biogas and bio-gas industry has ushered in a rare historical development opportunity.

■ Scientific system and mechanism

And policy system to be built

At present, the conditions for large-scale, industrial and industrial development of biological gas have been basically mature, and the key is to further improve regulations and policies, break down industry barriers, and scientifically build institutional mechanisms and policy systems to promote the sustainable development of biological gas.

First, we must clearly position and implement the "two-wheel drive" strategy. First of all, it should be clear that biological gas is an indispensable part of China's modern energy system, and the strategic role of biological gas in realizing the "dual carbon" goal, promoting the low-carbon energy transformation and ensuring energy security should be positioned at a higher level and with a broader vision. Secondly, it is necessary to clarify the leading departments, do a good job of top-level design and medium - and long-term planning, implement environmental protection and low-carbon energy, "two-wheel drive" development strategy, implement the supervision and assessment mechanism, and promote biomass natural gas to enter the fast lane of sustainable development as soon as possible.

Second, we will speed up the revision and improvement of the Renewable Energy Law. In order to build a green modern energy system as the goal, highlight the role of biological gas emission reduction of carbon dioxide and methane, clear green electricity, green gas quota system, biogas power generation and biogas grid connection enjoy full protection of the purchase policy, to ensure that biogas power generation subsidies in place in time. As soon as possible, biogas and biogas will be included in the carbon trading system.

Third, strengthen the gas top design and planning. Clarify the strategic positioning of biological gas in the future gas energy, and realize the coordinated development of natural gas and biological gas. It is necessary to jump out of the limitation of developing biological gas only in the field of rural energy, and plan the development of biological gas industry with industrial thinking to make up for the shortage of natural gas industry and provide clean energy for urban gas and vehicles.

Fourth, we should build a diversified gas supply system. The integrated development of natural gas and renewable gas is an international trend. Under the premise of ensuring safe supply, we should conform to the historical trend and trend, actively promote the low-carbon transformation of the natural gas industry, and build a multi-gas complementary, synergistic, clean and low-carbon multi-gas supply system with natural gas as the main part and renewable gas such as biological natural gas and hydrogen as the supplement. Central enterprises and urban pipe network enterprises should take the initiative to assume the responsibility of promoting biological natural gas, the competent authorities should be in accordance with the renewable energy power generation quota management measures, as soon as possible to introduce the relevant policies of biological natural gas quota indicators, the implementation of quota incentives and penalties, to provide market space and impetus for the promotion of biological natural gas.
