Electrification (direct)


Technology Description

Kilns - the main unit producing clinker for cement production - require high temperature heat and typically run on fossil fuels. Exploration is underway to electrify the heating process, through technologies such as the plasma arc or resistance-based heating.

Relevance for Net Zero

The TRL indicates that this option is at a lower phase of development, and it must be coupled with renewable electricity production in order to achieve considerable emission reductions. Considerable progress would be required to bring it to commercialisation and enable it to compete with alternatives. Furthermore, the technology would address energy but not process emissions from cement production.
