This writer obviously has not heard of LaFarge and Mantra Energy MVTG!!!! OR the witter has an agenda to sell CCS!!! LOL
World cement production in 2011 reached 3.6 billion tonnes. This resulted in over 2 billion tonnes of CO2 being produced from both the calcination of limestone and the fuels used (mainly coal and gas) to drive this process.
The global cement sector has been very active in reducing its emissions from cement production. The three levers that have been used are:
Energy efficiency,
Alternative fuels or biofuels, and
Clinker substitution.
Through the combination of these efforts, the emissions per tonne of cement have been reduced by 16 percent from the 1990 levels of 750 kg CO2/ tonne of cement. Further reductions can be achieved through continued action using these three levers but there is a practical limit on the reductions that can be achieved. Hence deep cuts in CO2 emissions from cement production can only be achieved through CCS.
This writer is dead wrong!!!!! ERC is the answer not CCS!!!! Time for some posts from us on that page, awareness posts to clue the writer and readers into MVTG's profitable CO2 to Formic acid ERC process and reactor!!!
Ambition with out knowledge is like ship in dry dock. Going nowhere fast!
