Fuel switching is essential to cement decarbonization strategy, including the U.S. roadmap published by the Portland Cement Association (PCA). Despite this, the average U.S. thermal substitution rate (TSR) is far lower than in other developed economies. The EU's average TSR is about 52%, although considerable regional variation exists.

The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.
