Bioenergy - power plant capacity worldwide 2019

Bioenergy power plants in China had the largest capacity in the world at 22.5 gigawatts in 2019. The global capacity of bioenergy plants totaled approximately 140 gigawatts. Biomass demand Bioenergy is one of the largest contributors to renewable energy demand – traditional biomass use in developing countries and more modern uses for biomass account for a large part of bioenergy consumption. Although fossil fuels remain the primary source for heating, the combustion of biomass acts as a renewable heating source. Traditional use of biomass occurs when wood biomass or charcoal, as well as dung and agricultural residues are burned in simple devices.Modern biomass combustion plant As seen in the traditional combustion of biomass for heat, modern uses of biomass can be complex due to the nature of the materials used. Some biomass requires pre-treatment before being burned. The heat from the combustion is used to fire the boiler, generating hot water or steam, which turns a turbine that produces electricity.

2019年，中国生物能源发电厂拥有全球最大的装机容量，达到22.5吉瓦。全球生物能源发电厂的总装机容量约为140吉瓦。生物质需求方面，生物能源是可再生能源需求的最大贡献者之一——在发展中国家，传统生物质的使用以及生物质更为现代的应用占据了生物能源消费的很大部分。尽管化石燃料仍然是供暖的主要来源，但生物质的燃烧充当了可再生能源供暖的来源。传统的生物质使用方式出现在木材生物质或木炭、粪便以及农业残留物在简易设备中燃烧的情况下。现代生物质燃烧装置中，由于所用材料的特性，生物质的现代应用可能相当复杂。某些生物质在燃烧前需要预处理。燃烧产生的热量用于加热锅炉，产生热水或蒸汽，进而驱动涡轮机发电。
