Abstract

Bamboo is widely grown in Indonesia and is a potential energy crop for people living in rural areas. The implementation of bamboo gasification in Mentawai Island, one of rural and remote small islands in Indonesia, which follows the principle of a community-based renewable energy system, is expected to replace unsustainable conventional diesel power while also improving the socio-economic condition of the community. Life cycle assessment and techno-economic analysis are conducted to assess the community bamboo gasification system in terms of its global warming impact and economic viability. The global warming impact of community bamboo gasification ranges from -11 to 76 g CO2eq/kWh, with the highest contribution originating from synthetic fertilizer production. With a starting bamboo price at $0.01 per kg and an electricity price at $0.20 per kWh of electricity produced, the system shows a positive net present value and a levelized cost of electricity around $0.20 per kWh. This study showed that community bamboo gasification is environmentally better than conventional diesel power and average rural solar photovoltaic energy. From an economic standpoint, the pricing scheme for a specific community energy system must be developed along with political intervention to regulate a better subsidy for renewable energy application. However, when considering the carbon abatement cost, a potential saving of up to $84 per ton CO2 is expected by replacing diesel power with bamboo gasification.
