Life cycle inventory analysis of waste wood to hydrogen for domestic energy sector: Case study: Indonesia

This study analyze the cradle to gate total CO
2
emission of the bio-hydrogen supply chain system in Indonesia. Waste wood from forestry area collected as a feedstock of hydrogen power plant in the capital city of forestry area. A life cycle inventory as part of life cycle assessment methodology is use to evaluate the emission of the new energy system. The system boundary are including harvesting, collecting, chipping, delivering the feedstock and energy conversion process. The objective of this study is to see identify the key indicators to minimize the CO
2
emission of the supply chain system of the bio-hydrogen from wasted wood. The results showed that the 7% of the potential bio-hydrogen in Indonesia could supply domestic sector energy demand for 134 cities. The energy system produces 5.89 × 10

/years. The energy conversion process contributes 86% of the total emission. The new system can reduces the CO
2
emission about 95% of domestic sector in 134 cities in Indonesia.
