What a contribution biomass makes to carbon neutrality!

Biomass is twice as large as global energy consumption needs

According to the Blue Book, biomass refers to various organisms formed through photosynthesis, including all animals, plants and microorganisms. The earliest energy used in human history is biomass energy. The so-called biomass energy is the storage of CO2 by solar energy through photosynthesis and the conversion of chemical energy in biomass, that is, the energy using biomass as a carrier. It is directly or indirectly derived from the photosynthesis of green plants, can be converted into conventional solid, liquid and gaseous fuels, inexhaustible, is a renewable energy, but also the only renewable carbon source. It has been calculated that the energy stored by biomass is two times greater than the current total energy consumption in the world.

In the process of using biomass energy as a zero-carbon energy source, if the carbon collection and storage process is increased, the collection of CO2 generated can create negative carbon emissions, which can become one of the ways of environmental restoration. Negative carbon emissions are widely seen as an integral part of limiting global warming and achieving carbon neutrality. Biomass energy not only has zero carbon energy properties, but also will play an active role as a negative carbon energy.

In order to control the global average temperature rise within 2 ° C of the pre-industrial level, the parties to the Paris Agreement are striving to achieve carbon emission reduction targets, and many countries have put forward their own carbon emission reduction requirements, in which biomass energy plays a huge role.

 Carbon peaking and carbon neutrality is China's solemn commitment to the global response to climate change. It is a major strategic decision China has made based on its responsibility to promote the building of a community with a shared future for mankind and the inherent requirement of achieving sustainable development. It is also an inherent need for China to promote economic transformation and upgrading.

The IPCC points out that economic development has historically been closely associated with increases in energy use and greenhouse gas emissions. Renewable energy can help to break away from this correlation and thus contribute to sustainable development. Bioenergy has significant potential to reduce greenhouse gas emissions if resources are sustainably exploited and efficient technologies are used. Certain existing systems and important future options, including multi-year crops, forest products, biomass residues and waste, and advanced conversion technologies, have the potential to deliver significant GHG reductions, i.e. emissions reductions of 80-90% compared to baseline fossil energy values.

The development of biomass energy can also solve the problem of harmless and reduced treatment of all kinds of organic waste in urban and rural China. If biomass waste is not effectively used, in the case of natural decomposition, methane and other gases with stronger greenhouse effect will be released. Therefore, social values such as the environment, people's livelihood and zero carbon of biomass energy need to receive sufficient attention. In the context of comprehensively promoting the rural revitalization strategy, the future development of biomass energy will need to take a "agriculture - environment - energy - agriculture" green low-carbon closed cycle development road, in power generation utilization and non-electric utilization, biomass energy plays an important role in promoting the overall improvement of township energy structure.

By 2060, the carbon emission reduction of biomass power generation will exceed 460 million tons

As an internationally recognized zero-carbon renewable energy, biomass energy is widely used in industry, agriculture, transportation, life and other fields through power generation, heating, gas supply, etc., and can not be replaced by other renewable energy sources. When combined with BECCS (Bioenergy and Carbon capture and storage) technology, biomass creates negative carbon emissions. In the future, biomass energy will make great emission reduction contributions to China's carbon peak in 2030 and carbon neutrality in 2060 in various fields.

At present, China's biomass resources are about 461 million tons of energy utilization, and the carbon emission reduction is about 218 million tons.

2020 biomass energy utilization (tons) and carbon emission reduction (tons)

Under the background of carbon peak in 2030, biomass energy utilization mainly realizes the replacement of fossil energy in the fields of power supply and heating. From 2021 to 2030, biomass clean heating and biological natural gas can effectively replace coal use in counties, build distributed energy stations in counties and villages, and completely change the energy use structure in rural areas. The application of biomass clean heating and biological gas generates clean energy while treating various types of waste, providing heating and gas for residents, and helping achieve comprehensive rural revitalization. It is estimated that by 2030, the use of biomass energy in various ways will reduce carbon emissions for the whole society by more than 900 million tons.
