Abstract [en]

This paper examines the potential for energy (i.e. bioethanol and bioelectricity) production and fossil fuel substitution in Indonesia based on sugarcane feedstock. Indonesia is one of the top ten cane producers in the world, and has huge potential to produce bioethanol and bioelectricity. Current agricultural practices, industrial milling operations, supply-chain management, and feedstock (i.e. sugarcane) supply and main/co-products (i.e. sugar, molasses, and bagasse) production and their demand/utilization are identified. At present conditions, around 350 million litres bioethanol can be annually produced in Indonesia using sugarcane molasses (a low-value co-product). In addition, approximately 400 MW surplus bioelectricity can be generated and connected to the grid using the state-of-the-art or efficient bagasse cogeneration technologies in sugar mills. The substitution of fuel ethanol in transport helps reduce the imports of subsidised oil products while bioelectricity substitutes coal based electricity in the nation. Associated climate benefits, i.e. climate change mitigation potential, will also be estimated. The study also explores the potential of fuel ethanol and power production considering the improvement of cane yield and the expansion of sugarcane field as the country wants to modernize sugarcane sector and expand the cultivation areas aiming at achieving sugar self-sufficiency. Indonesia has set differentiated and time-bound mandatory biofuel targets, and sugarcane is one of the main feedstocks for bioethanol production. Therefore, it is vital to scrutinize how sugarcane bioethanol could help meet the target in synergy with agricultural, industrial and energy development in a sustainable way.
