Options for mitigating CO2 emissions from cement plants range from carbon capture to alternative fuel substitution; this work examines the application of a solid, microalgae-derived biofuel as one option for the latter. Based on technologies that have been demonstrated to work at industrial scales, this work examines two potential systems for the production of such a biofuel: in one case yielding a 2-part solid fuel of microalgal biomass (85 wt.%) and water (15 wt.%), with an expected heating value of 18.6 GJ t-1, and in the second yielding a 3-part solid fuel of microalgal biomass (80 wt.%), water (15 wt.%), and limestone dust (5 wt.%), with an expected heating value of 17.4 GJ t-1. A preliminary economic analysis using published literature values for equipment costs and capacities determines the cost of the 2-part fuel to be $34.5 GJ-1 and the cost of the 3-part fuel to be $36.9 GJ-1. These represent more economical approaches to producing biofuel from microalgal biomass than liquid biofuels, the most economically competitive of which is still priced near $48.6 GJ-1. However, these cases also represent a significant cost increase over traditional solid fossil fuels, such as coal at a standard cost of $2.34 GJ-1. Ultimately, applying microalgal biomass to as a thermal energy source in clinker manufacture is expected to cost $241 tCO-2.
