Cemvision electrifies clinker production by replacing fossil fuels with clean energy — hydrogen, plasma, resistive heating, biofuels, and more — in a standard rotary kiln. Rather than betting on a single technology, our flexible process combines the best available energy sources for a fully fossil-free production pathway. The result: better energy efficiency, grid balancing support, and high-performance cement with a minimal carbon footprint.

The world doesn't need more cement plants. It needs better ones. Our process retrofits existing infrastructure, converting conventional plants into near-zero cement producers — and giving stranded assets a second life.

Cemvision’s electrification cornerstones:

Our approach is not just climate-friendly; it’s highly pragmatic, resource-efficient, and resilient.

‍

Hydrogen combustion produces only water vapour — a highly effective heat transfer medium that allows Cemvision to reach the temperatures required for clinker production with zero fossil emissions. Hydrogen can be produced when electricity is available and stored to be used when needed. 

‍

Plasma heating uses ionised gases driven by an electric arc to generate temperatures up to 20,000°C, making it one of the most powerful fossil-free heat sources available and well-suited to the intense demands of cement manufacturing. Successful trials show that plasma burner can  replace the  traditional burner as single heat source. 

‍

Resistive heating works like an industrial-scale electric element, heating the kiln from the outside in. Cemvision's trials have already demonstrated high clinker quality, paving the way for modular kiln designs and future industrial-scale deployment.

‍

Electric flow heaters warm air through a resistive element, then circulate that heated air directly into the kiln to heat the material by convection. This approach offers precise temperature control and clean, fossil-free operation, perfectly suited to act as a bulk  energy source for the process.
