The title of this post, is the same as that of this article on the Construction Index.
Lime is one of those materials that plays a large part in our lives without our even knowing it. The Wikipedia entry lists a multitude of uses.
The article starts with these paragraphs.
The trial, led by Tarmac at its Tunstead site near Buxton, was the culmination of a project to demonstrate the potential to use hydrogen as a viable fuel alternative to natural gas for commercial-scale production of lime.
A number of trials were conducted with differing energy replacements, which culminated in a 100% replacement of the natural gas.
While it has been shown to be feasible, we have not yet been told how soon it might be practical or affordable.
The article finishes with this optimistic statement.
Tarmac, a CRH company, has cut CO2 by 24% per tonne of product since 1990; it is aiming for 45% by 2030.
This article illustrates how some important industries create a lot of carbon emissions and how decarbonisation would be fairly easy with a plentiful supply of hydrogen.
This is also the sort of industry, that would benefit from blending up to twenty percent of hydrogen into the UK's natural gas supply, as is currently being investigated by the HyDeploy project.
