Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy, that is, energy with biomass as the carrier. It is directly or indirectly derived from the photosynthesis of green plants and can be converted into conventional solid, liquid and gaseous fuels, which are inexhaustible and inexhaustible. carbon source.
Why focus on the development of biomass energy?
With the rapid consumption of fossil resources and the continuous deterioration of the ecological environment, all countries in the world, especially major powers, regard the development of new energy and renewable energy as the focus of a new round of industrial development, increase investment and make efforts to promote it. Biomass, as the only renewable resource that can be converted into gas, liquid and solid fuels and has a two-way cleaning effect, has attracted widespread attention from most countries in the world.
What are the characteristics of biomass energy?
1) Renewability: Biomass energy is a renewable resource. Biomass energy can be regenerated through photosynthesis of plants. It is a renewable energy source such as wind energy and solar energy. It is rich in resources and can ensure the sustainable use of energy;
2) Low pollution: biomass has low sulfur content and low nitrogen content, and generates less SOX and NOX during the combustion process; when biomass is used as fuel, since the carbon dioxide it needs during growth is equivalent to the amount of carbon dioxide it emits, Therefore, the net carbon dioxide emission to the atmosphere is close to zero, which can effectively reduce the greenhouse effect;
3) Wide distribution: in areas lacking coal, biomass energy can be fully utilized;
4) The total amount of biomass fuel is very rich: biomass energy is the fourth largest energy source in the world, second only to coal, oil and natural gas. According to biologists' estimates, the earth's land produces 100-125 billion tons of biomass every year; the ocean produces 50 billion tons of biomass every year. The annual production of biomass energy far exceeds the world's total energy demand, which is equivalent to 10 times the current world's total energy consumption.
