The Development Strategies and Technology Roadmap of Bioenergy for a Typical Region: A Case Study in the Beijing-Tianjin-Hebei Region in China

Abstract

The Beijing-Tianjin-Hebei region has abundant biomass resources, which are difficult to collect and thus are underutilized. However, the potential estimation of biomass energy can result in a comprehensive understanding of bioenergy resources in order to establish a technology roadmap for the region’s bioenergy development. Therefore, it is essential to estimate the potential of Beijing-Tianjin-Hebei biomass resources and bioenergy utilization. In this paper, the amount of main biomass resources for possible energy use and bioenergy utilization are calculated based on a statistical data estimation method for crop residues; human, poultry, and livestock manure; and municipal solid wastes. On the basis of biomass resources and bioenergy utilization potential, the technology roadmap is established. The results show that the amount for available biomass energy use is unevenly distributed in the Beijing-Tianjin-Hebei region, and the largest amount of resources is crop residues (36.52 million tons or 18.26 million tons coal equivalent). The biogas from human, poultry, and livestock manure and densified solids from crop residue technology roadmap is suitable for the Beijing-Tianjin-Hebei region.

Constructing Rainfall Threshold for Debris Flows of a Defined Hazardous Magnitude

“…This region is characterized by rugged and steep terrain, as well as active tectonic movements [17,[27][28][29][30][31][32]. Precipitation is concentrated mainly between July and September, whereas spring and winter are relatively dry, with an average annual rainfall of approximately 480 mm [33][34][35]. Residents in this area are confronted with a heightened risk of debris flow hazards [36][37][38].…”

Development status and some considerations on Energy Internet construction in Beijing-Tianjin-Hebei region

“…In Tianjin, the methane production from municipal solid waste via landfill treatment is 0.04 million tons [ 25 ]. The Tianjin Ninghe Biomass Power Generation Project, which was completed and put into operation in 2018, has a construction scale of processing 500 tons of domestic waste per day, and the straw incineration power generation project has a scale of processing 300,000 tons of biomass straw per year [ 26 ].…”
