Global cement direct CO2 emissions reductions, 6DS vs 2DS
The 2DS requires a mix of technologies, and significant decoupling of CO2 emissions from energy use
Thermal intensity (GJ/t clinker) reduced by 17%
Fossil fuel share 82% 56%
% of CO2 captured <1% 32%

... but further decarbonisation is needed for a well-below 2DS pathway.
Decarbonizing energy-intensive industries is critical, requiring accelerated technology and policy innovation

Specific EH recoverypotentialThermal energy intensity
NOTE: IEH technical assessment based on 2013 stock data. Specific energy savings in GJ/t cement refer to global dry- process-based clinker production. IEH estimates refer to a dry-process kiln with five-stages of pre-heater and pre-calciner and to raw materials with a moisture content of 2-6% (low-range).
Global excess heat recovery technical potential – Cement
Globally, 6% of the final energy use in cement making could be technically recovered
While expanding spatial boundaries can achieve greater energy savings …

Low-carbon cement technology RD&D is promising, but progress must be accelerated
© OECD/IEA, 2016
CCS is currently not on track to meet IEA Cement Technology Roadmap targets (2009) 3 oxy-fuel demos & 3 chemical looping demos by 2020
Scaling up of CCS and significant cost reductions in oxy-fuelling by 2030; widespread deployment by 2040
Further improvements in cost and deployment through 2050
… and greater investment and policy support is needed to accelerate progress.

Priorities for the global cement industry
Achieving BAT performance is critical, while accelerating low-carbon innovations is essential BAT includes energy and resource efficiency (e.g., clinker ratios)
The pace of CCS deployment must increase
Low-carbon cements can be a major breakthrough
Biomass/waste fuels can reduce emissions, but supplies may be uncertain
Expanding boundaries of influence can create new opportunities Waste heat recovery for local plants/buildings
Materials efficiency in end use product applications
Multiple aspects of strong policy support are needed: Long-term energy and climate policy signals
Increased support for technology RD&D
Low-carbon and energy efficiency labels and standards
