Biochar gel refers to a kind of nano-scale porous solid material made from agricultural waste, plant fibers and other biomass through advanced processing. Biochar gel has many advantages such as high specific surface area, environmental friendliness, good mechanical properties, excellent heat insulation, and good adsorption capacity. It is applicable in various fields including construction engineering, environmental protection, biomedicine and battery manufacturing. 
Depending on the type of substrate, biomass aerogels can be classified into various types such as lignin aerogels, cellulose aerogels, plant tannin aerogels, chitosan aerogels, water-soluble polysaccharide aerogels, and protein aerogels. Cellulose aerogels are the mainstream products in the biomass aerogel market. They are usually made from plant cellulose and can be used as adsorbents after hydrophobic modification. They have a strong demand in water treatment scenarios. In the future, as the development speed of cellulose aerogels accelerates, the market space for biomass aerogels will be further expanded. 
Biochar aerogel belongs to biomass materials. In recent years, the country has attached great importance to the development of the biomass material industry and has introduced a number of encouraging policies, including the "Three-Year Action Plan for Accelerating the Innovation and Development of Non-Cereal Bio-based Materials", and the "Action Plan for Enhancing Standards and Leading the Optimization and Upgrading of Raw Materials Industry (2025-2027)". With the support of national policies in the future, the development trend of the biochar aerogel industry in China will continue to improve. 
According to the "2025-2030 China Biomass Aerogel Industry Market in-depth Research and Development Prospects Forecast Report" released by the industry research center, biomass aerogel has excellent performance and wide applications. Its main demand sectors include construction engineering, environmental protection, biomedicine, and battery manufacturing. In the construction engineering field, biomass aerogel has functions such as sound insulation and heat insulation, and can be used as building wall materials; in the environmental protection field, it has adsorption properties and can be used in water treatment and air purification scenarios; in the biomedicine field, it has biodegradability and biocompatibility, and can be used as a drug sustained-release carrier; in the battery manufacturing field, it can be used to manufacture battery housing, mainly serving the functions of heat insulation and flame retardancy. 
Industry analysts have stated that biochar aerogel, as a type of biomass material, is widely used in various fields. In the future, as the downstream industry develops at a faster pace, the demand for biochar aerogel in China will further increase. Currently, the biochar aerogel industry in China is still in its infancy and has not achieved large-scale application. In the future, with the continuous efforts of local enterprises and technological progress, its market space will be further expanded.
