Randomized trial assesses decarbonization pathways in cement manufacturing, indicating hydrogen's potential impact.

The aim is to evaluate effective decarbonization pathways for the cement industry, focusing on hydrogen utilization.
Assessment based on mass and energy balances from literature benchmarks and industrial data.
Evaluation of various decarbonization pathways including energy efficiency, alternative fuels, and hydrogen utilization.
Analysis of emissions reductions associated with each decarbonization approach.
Energy efficiency measures yield limited reductions of 10–30 kg CO2/t cement.
Alternative fuels and clinker substitution can provide larger reductions but remain partial.
Hydrogen could reduce emissions by 50 to 200 kg CO2/t cement, especially with oxy-fuel combustion systems.

Franco et al. (2026) studied this question.
