Biomass power generation, the most stable renewable energy source for heat and electricity

There is a view in the power industry that no electricity can have both: the triangle of cheapness, greenness and stability. This impossible triangle theory continues to this day and still has a big market. For example, coal-fired power generation is cheap, stable and reliable, but the intensity of carbon dioxide emissions is very high; although hydropower, wind power and photovoltaics are environmentally friendly, their power generation is unstable due to seasonal and natural factors. However, agricultural and forestry biomass power generation is different from the above-mentioned types of electricity, and can completely subvert the impossible triangular theory of cheapness, environmental protection and stability. Compared with wind power and photovoltaics, it is more efficient and stable renewable energy. Power generation efficiency far exceeds that of wind power and photovoltaics: In 2020, the grid-connected wind power generation will be 466.5 billion kWh, and the grid-connected solar power will be 260.5 billion kWh. At that time, the total installed capacity of wind power was 281 million kilowatts, and the total installed capacity of photovoltaic power generation was 253 million kilowatts. The installed capacity of biomass power generation is 13.3 million kilowatts, and the power generation capacity is 57 billion kilowatt hours. The installed capacity of wind power is 21 times that of biomass power generation, and the installed capacity of photovoltaic power generation is 19 times. The power generation is 8 times and 4.5 times respectively. It should be pointed out that biomass power generation follows the route of determining electricity by heat, and more than 40% of the energy is used for heating. If the biomass power plant generates all the electricity, the power generation efficiency is higher. According to relevant data, for wind power, photovoltaic and biomass power generation with the same installed capacity, if only power generation is considered without heat supply, biomass power generation will be about 5 times that of wind power and about 8 times that of photovoltaics. The only renewable heat source in the world my country is promoting clean energy power to replace coal power, and renewable energy power generation can replace part of coal power power, but when it comes to residential central heating and industrial production heat load, wind power and photovoltaics are powerless. Biomass energy is the only renewable heat source in the world. In the future, biomass power generation will be the mainstream of heat-based electricity generation and cogeneration. Biomass thermal power will fill the heat gap after coal power has been de-capacity. Especially in small and medium-sized towns and industrial parks, biomass clean heating and biomass cogeneration projects have become the core main force of energy supply, and become the energy guarantee for residential heating and industrial production. my country has enough biomass fuel to support the construction of thousands of biomass power plants, and biomass power generation is also the only industry that can process agricultural and forestry wastes on a large scale, and it is the most stable renewable energy source for heating and power supply.
