Swedish cement producer Cementa AB and the state-owned energy major Vattenfall have teamed up to develop electricity powered cement production and zero carbon emissions.
They have launched CemZero, a joint pilot study into electrified cement production with the objective of ensuring zero carbon dioxide (CO2) emissions by 2030. If successful this reduce Sweden’s total CO2 emissions by some 5 %
Cementa (a wholly-owned subsidiary of Germany-headed HeidelbergCement AG ) has already made great strides on energy efficiency improvements and phasing out fossil fuels in cement production at its three production facilities in Sweden. According to Cementa, its climate impact is already 15 % lower than the global average.
Through the CemZero projects it is targeting zero CO2 emissions from cement products during their life-cycle.
Concrete is the world’s most common building material, demand for cement will remain high in the future due to population growth and increased urbanisation.
“It is very positive that we are working together with Cementa to find a solution, as a climate-smart, electrified cement industry can make an important contribution to our joint efforts to reduce climate impact,” said Magnus Hall, President and CEO at Vattenfall.
“Electrification within the industry is an important element in the transition to sustainable urban development. We are now going to develop knowledge within the field in order to ascertain together with Vattenfall whether it is a potential future solution for cement production,” added Jan Gånge, CEO of Cementa.
The Cementa plant on the island of Gotland (see photo) produces 2.5 million tonnes of cement products per annum. The plant has already replaced around 40 % of coal previously used as fuel with refuse derived fuel (RDF) and waste wood supplying excess heat to district heating and power to the grid.
