Cementa completes feasibility study on electrified cement production

Sweden: HeidelbergCement’s subsidiary Cementa has completed a feasibility study into electrifying its cement plant at Slite in Gotland as part of its Cemzero project. A report from the first phase of the project has been submitted to the Swedish Energy Agency.

The study found that using electricity to supply heat during the clinker production process is possible using plasma technology, although this needs to be tested on a larger scale. Using an electrified process was found to be competitive compared to other options for achieving high reductions in carbon emission. The production cost of cement would be doubled approximately but the research suggested that this might only mean a small percentage increase to the end cost of a building or an infrastructure project. Finally, the study reported that any future electrification of the Slite plant would work well with a planned expansion to wind turbine generation at the site. It would improve the energy balance and reduce the maximum power surplus that might occur.

Cementa and energy company Vatenfall will now look at how to build a pilot plant.
