Production quantity and energy yield of residual sugarcane biomass in Vietnam per year. Region Sugarcane Bagasse Sugarcane Trash Production (t) Energy Potential Production (t) Energy Potential (TJ) (TWh) (TJ) (TWh) Northern Central area and Central coastal area 1,903,106 19,792 5.50 1,268,737 14,717 4.09 Central Highlands 1,182,730 12,300 3.42 788,487 9146 2.54 Mekong River Delta 1,000,563 10,406 2.89 667,042 7738 2.15 Northern midlands and Mountain areas 631,599 6569 1.82 421,066 4884 1.36 South East 595,547 6194 1.72 397,032 4606 1.28 Red River Delta 31,727 330 0.09 21,151 245 0.07 Vietnam 5,383,650 55,989.96 15.55 3,589,100 41,633.56 11.56 Results show that the total energy potential of sugarcane biomass in Vietnam is more than 27 TWh. This amount of energy could cover the energy consumption of about 6 million households, with the share of bagasse only 1.3 times greater than that of sugarcane trash. The Northern Central area and Central coastal area region has the highest energy potential (nearly 9.6 TWh in total) due to the extensive cultivation of sugarcane, followed by the Central Highlands and the Mekong River Delta regions. The Mekong River Delta region has almost twice as low energy potential as the topmost region. The total calculated energy potential of residual sugarcane biomass in the Northern Central area and Central coastal area region makes up one-third of the entire country, and it is equivalent to the yearly energy consumption of over 1.2 million households in case of bagasse and below 1 million households for sugarcane trash. Subsequently, Northern midlands and Mountain areas and the South East regions together represent only about 20% of the country’s energy potential. The minor production of sugarcane and thus the smallest energy yield of residual biomass lie in the Red River Delta region (only 0.16 TWh totally). Here, however, the energy stored in sugarcane residues could still satisfy the energy needs of more than 35 thousand households. Table 9 presents the energy potential of sugarcane bagasse as well as sugarcane trash in the top five producing provinces. Gai Lai and Dak Lak are situated in the Central Highlands region, and the rest of the provinces are located in the Northern Central area and central Coastal area region. |
