What Is a Biomass Power Generator?
A biomass power generator is a device that generates electricity using biomass resources as fuel. Biomass resources are not fossil fuels such as petroleum or coal, but resources derived from plants and animals that can be reused. Power is generated by rotating a turbine with steam or gas generated by burning biomass fuel. Therefore, as a power generation method, it is classified as thermal power generation. However, because it does not use fossil fuels, it is attracting attention as an eco-friendly power generator. In addition, the advantage of biomass power generation is that it is not only carbon neutral, but also stable.
Uses of Biomass Power Generators
Biomass power generators are used for the generation of electricity. They range from relatively small ones used in factories to large ones operated by electric power companies. In Japan, large-scale power plants are located in Gunma Prefecture, Niigata Prefecture, and Hokkaido. Small biomass power generators has generating capacity of about 50 kW. However, the larger the biomass power generators, the higher the power generation efficiency, and the smaller the generator, the lower the power generation efficiency. Therefore, it is necessary to consider power generation efficiency, power generation capacity, and running costs.
Principle of Biomass Power Generators
Biomass power generators can be broadly classified into three categories according to the principle of power generation. Since the characteristics differ depending on the power generation principle, it is necessary to select the most suitable method according to the intended use and required power generation capacity.
- Direct Combustion Method
The direct combustion method uses thinned wood, combustible garbage, waste oil, etc. as fuel and burns them directly. The thermal energy generated during combustion is used to boil water and rotate a steam turbine. Generally, thinned wood is cut into small pieces to optimize combustion efficiency. However, this combustion method does not provide a high-temperature environment, so the smaller the equipment, the lower the power generation efficiency. Therefore, this method is best suited for large-scale equipment. - Pyrolysis Gasification Method
The pyrolysis gasification method uses thinned wood or other materials as fuel. Biomass fuel is heat-treated at high temperature to generate gas, which rotates a gas turbine. This power generation method is characterized by its ability to achieve high combustion temperatures. This makes it an ideal power generation method for small biomass power generators. - Biochemical Gasification
Biochemical gasification differs significantly from other power generation methods in that it uses livestock manure and sewage sludge as raw materials. When these materials are fermented, biogas is generated. This biogas is used to rotate a gas turbine to generate electricity. In addition to being able to use biomass that is difficult to burn, the gas turbine is characterized by its high power generation efficiency.
Ultra-Compact Biomass Power Generators
Ultra-compact biomass power generators are also being developed. Some overseas manufacturers have developed ultra-compact biomass power generators measuring approximately 2.5 meters high x 4.8 meters long x 1.3 meters wide. Even with such small generators, equipment has been developed that can generate 40 kW of power and 100 kW of heat per unit, with an energy efficiency of approximately 78%. For example, in Akita Prefecture, an ultra-compact biomass power generators has been installed at a roadside station to supply hot water for footbaths and to heat plastic greenhouses during the winter.
Power Plants Using Biomass Power Generators
In recent years, the number of certified and operating biomass power generators has been on the increase. Many of these power plants rely on types of biomass such as wood pellets and PKS (Palm Kernel Shell: palm kernel shell after palm oil is extracted from palm seeds). In order for biomass power generation to be viable as a business, it is essential to have a system to ensure a stable supply of relatively inexpensive fuel, but this system is still inadequate.
As for international trends, the "Renewable Energy World White Paper 2020" published by REN21 (headquartered in France), an international network promoting renewable energies, is a useful reference. Globally, bioenergy is growing slowly, but the growth is particularly significant in China. China's recent growth in the bioenergy sector has been remarkable, and statistics from REN21 show that China has been the world's largest producer of biomass power for three consecutive years from 2017 to 2019. In Europe, on the other hand, many major countries are taking the prescribed path of moving away from coal, and there is a movement to switch to biomass, especially in Scandinavian countries such as Denmark, where it is also a popular heat source for district heat supply.
