Abstract: The present invention provides a stable fuel composition that can be used as a drop-in replacement for number 2 fuel oil without requiring infrastructure changes. The fuel comprises a continuous phase of mostly biofuel, an aqueous disperse phase, and at least one emulsifier. The continuous phase contains about 50 wt % to about 95 wt % of at least one liquid vegetable or liquid animal oil/fat or mixtures thereof; about 1 wt % to about 20 wt % of a renewable or fossil fuel derived thinning solvent or mixtures thereof, with or without 1 wt % to about 25 wt % of a C1-C4 monohydric alcohols, and with or without about 1 wt % to about 30 wt % of petroleum middle distillate. The aqueous phase contains about 1 wt % to about 50 wt % of deionized/purified water, with or without 1 wt % to about 25 wt % of a C1-C4 monohydric alcohols.
