Carbon Footprint Reduction in Ceramic Kilns: Which Role can Hydrogen Play in it?

The ceramics industry finds itself at the crossroads in selecting a path that would lead towards carbon
neutrality within the next 30 years. The energy-intensive firing kilns in each of the ceramic sub-sectors
are inextricably bound to a high level of carbon emissions, as they primarily use natural gas for meeting
their energy requirements. In this article, light has been shed upon the carbon footprint of the ceramics
industry, focussing mainly on the situation in Germany. The direct and indirect sources of carbon emissions
concerning kilns and their reduction measures have been outlined. Finally, the role of hydrogen in
minimising the carbon footprint of ceramic kilns has been delineated, by showing both the suitability and
challenges in substituting natural gas with hydrogen in the present ceramic kilns.
