Due to the lack of stable sources of raw materials, low technology conversion, difficult competition between costs and conventional energy sources, and unstable policies, biomass energy is developing slowly, but the situation has improved. By the end of 2017, biomass power generation installed capacity of 14 million 880 thousand kilowatts. The indicators proposed in the 13th Five-Year plan of biomass energy are expected to be completed ahead of schedule.

Green energy, also known as clean energy, refers to energy that does not emit pollutants and can be directly used for production and living. Green energy can be divided into two concepts: narrow sense and broad sense. The narrow sense of green energy only refers to renewable energy, such as water energy, biological energy, solar energy, wind energy, geothermal energy and marine energy. These energy consumptions can be restored and replenished with little pollution; green energy in a broad sense includes the selection of low-polluting or non-polluting energy sources for the ecological environment in the process of energy production and consumption, in addition to the above-mentioned renewable resources, including non-renewable resources, such as nuclear energy, natural gas, clean coal and so on. The green energy referred to in this paper is green energy in a broad sense, including non-renewable resources (low pollution or no pollution to the ecological environment).

Biomass refers to all kinds of organisms formed by photosynthesis, including all animals, plants and microorganisms. Biomass energy is the form of energy stored in biomass by solar energy in the form of chemical energy, that is, the energy carried by biomass. It is directly or indirectly derived from the photosynthesis of green plants and can be converted into conventional solid, liquid and gaseous fuels. There are many kinds of biomass available, which can be obtained directly from various crops and forest raw materials, as well as from by-products of the forest industry, the recycling of household waste, the recycling of destroyed wood and paper.

At present, China's biomass resources division has a potential to convert into energy of about 460 million tons of standard coal, has used about 22 million tons of standard coal, there are about 440 million tons of standard coal can be used as energy; in the future, with the expansion of afforestation area and economic and social development, the potential of biomass resources into energy can reach 1 billion tons of standard coal.

From 2010 to 2017, the installed capacity of biomass and garbage power generation in China has shown an upward trend. The cumulative installed capacity has increased from 5.6 GW in 2010 to 15.3GW in 2017, which has increased twice in seven years.

From 2010 to 2017, the grid-connected capacity of biomass power generation in China is on the rise. In 2016, the grid-connected capacity of biomass power generation in China was 12.14 million kilowatts. By the end of 2017, the grid-connected capacity reached 14.76 million kilowatts, an increase of 21.59% over the previous year.

Development trend of biomass power generation in China

(1) agriculture, forestry and biomass power generation will enjoy the advantage of first aid when breaking through economic bottlenecks.

Agricultural and forestry biomass direct-fired power generation is the most common biomass power generation technology. Take straw as an example, straw power generation refers to a kind of power generation method which takes the crop straw as the main fuel, feeds the straw into the boiler to burn directly, produces the chemical reaction, releases the heat, uses these heat to generate electricity again, the straw power generation is the straw. One of the most important forms of optimal utilization of straw.

(2) the maturity of biomass fuel storage and transportation system is increasing.

Rural areas are rich in biomass resources. Generally speaking, the amount of local Collectible resources is more than 10 times the demand of biomass industrial projects, and there is no shortage of supply. Therefore, as long as the acquisition mode is innovated and the meticulous management is strengthened, the biomass enterprises can greatly enhance the control ability of the fuel market.

(3) technological progress will gradually enhance the profitability of biomass power plants.

The upgrading of biomass power generation technology can effectively improve the thermal efficiency of the unit. In the case of using the same fuel, the output of more electricity. At present, high-temperature and ultra-high-pressure units have been used in biomass power plants, and the conversion efficiency has been raised to more than 30%. With the application of BIGCC and thermochemical technology in biomass power plants, the conversion efficiency of biomass power plants is expected to reach 39%. The breakeven point of fuel cost will be greatly improved.

From the policy development trend and the role of the energy base in supporting the development under the new normal economic situation, as well as the comprehensive factors such as the promotion of energy conservation and emission reduction to fulfill the commitments of China's entry into the WTO, it is expected that the installed scale of the bio-intelligent development industry will maintain a growth rate of 15% - 20% between 2018 and 2023, and China's bio-energy power generation by 2023. The installed capacity will exceed 40GW.
