Abstract
To date, irregularity and lack of power supply remain a global problem in the rural areas of underdeveloped and developing countries. This paper proposes a new concept for rural electrification by using palm oil mills to co-produce biodiesel from sludge palm oil. We performed a case study based on a medium-sized palm oil mill in Central Kalimantan. Approximately 2.5 tonnes of biodiesel could be produced daily using an enzymatic batch process and potentially support around 1,375 households of 4 people each in the surrounding areas. Subsequently, we performed a techno-economic assessment to study the commercial feasibility of the concept for rural electrification using the enzymatic biodiesel as opposed to commercial diesel. A 10% price deduction was applied to incentivize the local community to use the co-produced biodiesel. From our analysis, the rural electrification concept was found to be commercially viable with a return on investment of 29% and a breakeven period of less than 4 years of operation. Barring the short-term impacts of the COVID-19 pandemic and the price fluctuations of diesel and crude palm oil, the long-term commercial prospect of this rural electrification concept is attractive as it financially benefits both the rural community and the mill operators.
