what’s the feature of biomass energy
The research, development and application of biomass energy and petroleum substitute products are effective ways to ensure energy supply, reduce dependence on fossil energy, and solve future energy problems. At present, with the continuous consumption of fossil resources such as coal, oil and natural gas, the development and utilization of biomass energy has attracted more and more attention. Biomass is an organic substance formed by photosynthesis of green plants, directly or indirectly. It includes plants, animals and microorganisms other than fossil fuels and their excretions and metabolites. Biomass energy refers to an energy stored in the form of chemical energy by solar energy. The plant is photosynthetic, and the energy formed by direct or indirect means is the biomass.
With the continuous research on biomass energy and petroleum substitute products and the development and application of related technologies at home and abroad, it has now met the conditions for large-scale industrial production. Relevant experts and scholars believe that biomass energy, as an alternative to petroleum, hopes to become China's future oil substitutes and new energy sources, which will not only pose a threat to China's food security, but also to China's food production. To promote, it will also greatly promote the safe, stable and rapid development of China's energy industry.
Biomass energy characteristics
Biomass is a complex material consisting mainly of cellulose, hemicellulose, and lignin, as well as small amounts of tannins, fatty acids, resins, and inorganic salts. This renewable raw material has great potential for power generation and production of high value-added chemicals. As a new type of renewable energy, biomass energy has many advantages over other fossil energy sources:
- Renewability. Biomass energy can be regenerated by photosynthesis of plants. Compared with fossil energy such as coal, oil and natural gas, it is a renewable energy source with abundant resources to ensure the permanent use of energy.
- Low pollution. The non-metal content of sulfur, nitrogen and the like in biomass is low, and sulfur-containing compounds and nitrogen oxides generated by combustion are less. Since biomass absorbs carbon dioxide in the same amount as carbon dioxide emitted during growth, when used as a fuel, the net carbon dioxide emissions to the atmosphere are almost zero, which can effectively reduce carbon dioxide emissions and acid rain.
- The total amount is very rich. Biomass is the world's fourth-largest carbon energy source after coal, oil and natural gas. Biomass energy plants (referred to as “biomass resources”) are widely distributed. With the continuous development of agroforestry, there will be more and more biomass resources. Biomass resources can grow rapidly through large-scale planting, which guarantees their production.
- Security. Biomass energy is safe to use and there are no major safety incidents such as explosions and leaks.
- Wide applicability. It is used in many fields of national economy such as biogas, solid fuel compression molding, pyrolysis gasification, gas production, fuel alcohol production, and biodiesel.
In the current international situation, there is an urgent need to adopt unconventional sustainable energy to meet the growing demand for liquid fuels. The use of biomass for the production of biodiesel, biofuels and ethanol is approaching commercialization. The development of biomass energy will play an active role in ensuring energy supply, reducing dependence on the oil market and stabilizing economic development. It is an effective new way to solve future energy problems.
