A UK-based trial to utilise hydrogen as a viable alternative to natural gas for commercial-scale lime production has demonstrated significant potential to clean up the process.
Construction solutions firm, Tarmac, on Tuesday (July 5) announced that the project led by its Tunstead quarry site, near Buxton, UK, culminated in a 100% replacement of natural gas in its lime manufacturing process.
Lime is produced in high temperature kilns heating calcium carbonate from limestone to approximately 1,000oC. The replacement of natural gas with hydrogen ensures no carbon dioxide is produced from fuel combustion, H2 View understands.
