Biomass energy opens up alternative space
In order to realize the sustainable development strategy of the coexistence of human beings and the environment, all countries are stepping up efforts to promote the clean and low-carbon development of the energy system, promoting low-carbon energy to replace high-carbon energy, and renewable energy to replace fossil energy.
Among renewable energy sources, only biomass energy has the natural endowment to replace fossil energy sources. We can demonstrate this through the following cognitions.
1. Abundant biomass energy reserves
Biomass energy is the only renewable energy that can be used in gaseous, liquid or solid state, and it has the characteristics of universality, high energy value and strong availability in the world. China is rich in biological and natural resources. The annual agricultural and forestry wastes produced amount to 1.2 billion tons, including 700 million tons of straw, and 3.3 billion tons of organic emissions from poultry and livestock, equivalent to nearly 1.5 billion tons of standard coal.
Biomass energy is not only renewable, but also can realize artificial planting energy. It has revolutionized the way human beings obtain energy since the Industrial Revolution, allowing energy to enter the era of planting from the era of mining.
2. Conducive to the protection of the ecological environment
Although hydropower, wind power and photovoltaics are green power, their damage to the ecological environment is huge. Every year, due to the ecological and environmental problems caused by hydropower, wind power and photovoltaic construction, it has been criticized by the society. Biomass energy not only does not cause ecological problems, but also is the greatest protector of the ecological environment. Agricultural and forestry resources are the only renewable resources that can directly protect the atmosphere, ecology, and environment. Biomass energy is a natural green fuel. After combustion, from raw material regeneration to energy conversion, it can tend to zero carbon emissions throughout the cycle. Therefore, to achieve the goal of carbon neutrality, biomass energy has great potential.
3. Diversification of utilization modes
The comprehensive utilization model of biomass energy is very diverse and achievable: power generation, heat supply, gas production, oil production, biomass carbon production, all energy commodities required by industrial civilization, biomass energy can provide.
The diversified industries of biomass energy have made great progress, especially the biomass power generation with combined heat and power as the main energy supply mode, which has formed a very complete and mature industrial chain. Today, when coal power is being gradually reduced in production capacity, because coal-to-gas and coal-to-electricity conversions have fallen into cost bottlenecks, and wind power and photovoltaics cannot achieve stable energy supply, biomass thermal power is becoming the best alternative role for industrial production energy use.
4. Seamless energy substitution can be realized
The demand for energy in industrial production and social energy consumption is mainly reflected in: electricity, heat, gas, and oil; however, wind power, photovoltaics, and hydropower have limitations in these points, and cannot achieve stable and safe energy supply. Biomass energy is highly integrated with fossil energy, which can provide electricity, gas, heat and oil in a stable and safe manner without changing the existing energy infrastructure and structure system, realizing seamless energy substitution.
5. Utilization of global bioenergy
From the perspective of renewable energy utilization around the world, the proportion of biomass energy terminal use exceeds 50%, especially in Europe, the proportion of biomass energy in new energy exceeds 60%, far exceeding wind energy and solar energy.
A considerable number of countries in Europe use biomass energy as their basic energy source. In particular, biomass heating accounts for more than 80% of European renewable energy heating. In short, the development of renewable energy has a huge space for development. As a new type of energy, biomass will have a broad market prospect.
