Techno-Economic Study of Palm Kernel Shell Biomass Operated on a Engine Diesel Dual Fuel

The Indonesian government has implemented a carbon emission reduction program for Diesel Power Plants as part of its efforts to achieve Net Zero Emission (NZE) by 2060. The biomass-fueled power plant approach can reduce the use of fossil fuels and minimize carbon emissions. The purpose of this study was to determine the economic value of a dual-fuel diesel power plant with fuel oil and syngas produced through gasification, using dual-fuel diesel engine technology. Gasification process. The gasification used is a multi-stage downdraft gasifier model, with an optimal air ratio variation of 1:7:2 in the pyrolysis, oxidation, and reduction zones. An experiment was conducted on a diesel engine operating at a speed of 3000 rpm and subjected to various loads ranging from 500 Watts to 4500 Watts. The mass flow rate of syngas can be adjusted by opening four valves, and syngas is fed through the intake manifold of the diesel engine. The use of a dual-fuel engine, which combines syngas with biodiesel, can improve thermal efficiency and reduce B35 fuel consumption. This resulted in a reduction in the specific fuel consumption (SFC) value from 0.257 to 0.213 at a load of 3000 watts. Technoeconomic analysis shows that the utilization of this system has the capacity to generate lasting economic benefits, especially when considering environmental factors and accessibility of local resources.
