The world is seriously searching for an alternative to fossil fuels due to their tremendous environmental effect. However, renewable energy sources such as solar, wind, hydropower, and biomass were anticipated to be alternative energies. In this study, the amount of heat generated from the combustion of coal and charcoal briquettes derived from oil palm biomass was investigated and compared. Charcoal briquettes were made from the biochar obtained after the pyrolysis of empty fruit bunches (EFB) and mesocarp fibre (MF). Coal and charcoal briquettes were subjected to combustion via thermogravimetric analysis (TGA) at a 10oC min-1 heating rate to a maximum temperature of 850oC. The ignition and burnout temperatures were 235oC and 675oC for EFB, 254oC and 788oC for MF, and 368oC and 770oC for coal. The maximum heat released 0.06 W was obtained from EFB charcoal briquette followed by 0.05 W and 0.04 W from coal and MF charcoal briquette, respectively. This finding indicated that charcoal briquettes derived from oil palm biomass (EFB) could be one of the potential solid fuels that can be used for coal replacement.
