"14th Five-Year Plan", biomass power generation has entered an era of full profitability


Biomass power generation has been in China for 15 years. Looking at the development of the entire industry, it can be said that several companies are happy and sad. The overall economic benefits are not high, and it has always been a dark cloud over the industry.

However, after the 13th Five-Year Plan, with the adjustment of policies, the iterative update of equipment and technology, and the upgrading of the industrial ecology from power generation to cogeneration, biomass power generation has entered an era of full profitability.

1. Policy support to promote the healthy development of the industry

Compared with wind power and photovoltaic power grid parity, although biomass power generation electricity price subsidy has been adjusted, it basically retains the subsidy qualification, and the subsidy can apply for bank loans after the right is confirmed.

In addition to the electricity price subsidy, the biomass cogeneration project also enjoys a three-year clean heating subsidy, a 30% investment and construction subsidy during the construction period, and a local subsidy for the straw processing fee for the collection, storage and transportation.

The coal-fired electricity price rises by 20%, and the grid-connected electricity price for biomass power generation will also rise, further hedging the high fuel costs; and projects that have obtained the carbon emission trading right can pre-sell carbon emissions in advance, which is very profitable.

2. Clean energy substitution expands market space

After my country proposed the 3060 dual-carbon target, the replacement of fossil energy by clean energy has become a general trend. It is imperative to build a new power system and further promote the reduction of coal power capacity, which provides a new market space for biomass power generation.

After the reduction of coal power capacity, in addition to the shortage of power supply, the heat load required for industrial production will also become more tight. However, wind power and photovoltaics cannot solve this problem, and the cost of natural gas is too high for enterprises to use.

Combining various factors, the only biomass cogeneration project that can replace coal-fired power plants to provide enterprises with a stable heat source is far more economical than natural gas. If the fuel is stable, it can even be comparable to coal-fired heat sources.

3. Upgrading of equipment and technology lays a solid foundation for industrial development

Although the installed capacity of biomass power generation is small, it is also a typical heavy-asset investment project. The scientific selection of its core equipment technology determines whether the power plant can output electricity and heat load efficiently, stably and continuously.

For a period of time, most of the biomass power plants in my country have adopted the traditional coal-fired boiler technical route. As a result, the operation of the power plants is very unstable, the economic benefits are low, and biomass power generation is not profitable.

Recently, project parties investing in biomass power generation have paid more and more attention to the technological upgrading of core equipment, using biomass boilers specially adapted to the characteristics of biomass fuels, ensuring stable operation of power plants and increasing profitability.

Fourth, the industry has entered an era of full profitability

At present, it is a past tense to invest in biomass power generation to lose money. The first reason for losing money was mainly because it only engaged in power generation without heating, and used backward technical routes.

With the popularity of high-temperature and high-pressure biomass boilers in recent years, the newly launched biomass cogeneration projects have basically achieved profitability, especially in the industrial heat load market, which has become the most stable source of income for biomass thermal power.

The biomass power generation industry will become an important link in achieving the dual-carbon goal. Under the environment of policy support and energy substitution, biomass power generation will enter an era of full profitability during the 14th Five-Year Plan period.

Concluding remarks

At present, capital is still cautious about investing in biomass power generation. This is mainly due to erroneous preconceptions about the industry and misunderstandings about biomass power generation.

However, a very gratifying phenomenon is that since 2021, the number of new approvals and grid-connected projects for biomass power generation has increased a lot, which shows that biomass power generation has attracted more and more attention from capital.

As biomass power generation enters an era of full profitability, capital will increase the development of biomass power generation projects. At the same time, resource competition in areas rich in biomass fuel will become more intense.

The generator set control module adopts the microprocessor-based

The generation principle of biomass synthesis gas: biomass raw materials enter the reactor of the gasification furnace, after being heated and dried, and then as the temperature rises, its volatile matter is precipitated and pyrolyzed (cracked) at high temperature. The pyrolyzed gas and production The substance undergoes a combustion reaction with the supplied air in the oxidation zone to produce CO2 and water vapor. The heat generated by combustion is used to maintain drying, pyrolysis and endothermic reactions in the lower reduction zone. The gas produced after combustion passes down the reduction zone and reacts with the high-temperature carbon layer (C+CO2=2CO, C+HO2=H2+CO) to generate biomass synthesis gas containing CO, H2, CH4, CmHn, etc. It is drawn from the bottom, and is sent out for use after the purification system removes impurities such as tar.
