1 biomass gas (excluding biogas purified biogas) is a biomass gasifier by the biomass fuel high temperature cracking, and then filtered and purified renewable clean energy, natural gas is a mixture of hydrocarbon and non-hydrocarbon gases mainly methane, which is embedded in the ground.
Natural gas can have a calorific value of more than 8,000 to 9,000 calories per cubic meter, while the calorific value of biomass gas, depending on the feedstock, is usually in the range of more than 1,200 calories per cubic meter.
1 kcal = 1 Daca = 1,000 kcal = 1,000 calories = 4.186 joules; 1 MJ = 1,000 KJ.
Natural gas is generally extracted from the gas fields or imported via imported from foreign gas fields and transported by pipeline. The raw materials for biomass gas come from agricultural and forestry waste, such as straw, rice husks, wood chips, etc.
Natural gas is usually extracted from gas fields or imported through foreign gas fields and transported by pipeline.
The cost of natural gas comes from upfront exploration, pipeline construction, and high cost to the customer. For example, the average price of natural gas for non-residents in Hunan in 2021 is 3.12 yuan per cubic meter, and 3.07 yuan per cubic meter in Shandong, and there are many areas that will be charged according to the volume of gas used in the gradient, and the price of natural gas is only going up. Biomass gas raw material prices are cheap, only need to invest in the construction of the money, you can once and for all, and Baojie environmental technology and contract energy management model, do not need customers to invest in their own equipment, only need to pay for the purchase of biomass gas can be put into use, to the customer to save the initial investment in equipment costs. There are national policy subsidies, there is no ladder charge, whether it is the user's own investment in equipment, or and Baojie environmental technology contract energy management, the cost is close to one-third of the natural gas.
Natural gas is no additional revenue, and may even pay energy royalties, when the large enterprises more and more, natural gas will be more and more limited. Biomass gas residue is high quality charcoal that can be sold to fertilizer or charcoal plants.
The country has just released the "14th Five-Year Plan", which makes clear the direction of the bio-economy, and gives tax incentives and policy subsidies for biomass gas. Natural gas is not currently subsidized.
In the EIA classification, biomass gas belongs to the 93 category, and belongs to the 91 category of biomass pellets of highly polluting fuels are completely different.
Biomass gas is limited by regional feedstock, upstream feedstock, and cannot support mega projects.
The low calorific value of biomass gas makes it difficult to be applied to high-grade ceramics, direct drying and other businesses
