Heidelberg Plans Net-Zero Cement Plant For Sweden

The title of this post, is the same as that of this article on The Times.

Making cement creates about ten percent of man-made carbon emissions. See Wikipedia for CO2 Emissions From Cement.

Making cement needs a lot of energy and I suspect most comes from natural gas these days.

But I suspect there are ways to simply cut the carbon emissions.

• Making cement is a continuous process and I suspect adding carbon capture would be easier than with other industrial processes like steelmaking.
• Hydrogen rather than natural gas could be used to provide energy.

There also may be other ways of making cement. See Ecological Cement on Wikipedia.
