HeidelbergCement driving Carbon Capture and
Storage/Utilisation
HeidelbergCement in the world
Number 1 in aggregates, number 2 in cement,
and number 3 in ready-mixed concrete
HeidelbergCement
Italcementi
HeidelbergCement and Italcementi

to cement
1,6 ton limestone
+ 0,1 ton coal
=
1 ton cement
+ 0,8 ton CO2
We reached the turning point: coal fired power is out!
Mandatory to deploy CCS/CCU to reach our goals!
4 levers to reduce CO2
Energy efficiency 27%
Alternative fuels 19%
Clinker substitution 9%
Carbon Capture & S/U 46%
2016
The cement sector will face one of the highest costs for carbon
capture (excluding the power sector)

HeidelbergCement beliefs & strategy (I)
Carbon Capture and Storage (CCS) is required
for a full de-carbonization of cement industry
CCS needs financial supporting mechanisms to
be competitive* feasible *imports/steel
CCS lacking public acceptance in mainland EU,
sufficiently accepted in Scandinavia and Canada
Carbon Capture & Utilization (CCU) commercial
today for small high-value-end-products
CCU potential to significant contribute to CCS/U
targets for cement industry in focus
Reliable technology
Financially sound
Public acceptance
HeidelbergCement beliefs & strategy (II)
CCS and CCU are mainly in
pre-competitive phase
HeidelbergCement
encourages and initiates
collective approaches
– within the cement industry

ECRA
– and beyond

Carbon Capture
Large Scale Carbon Capture Norway
Test program 12 m€ final end 2016
– 75% funding government
– Amine scrubbing most reliable technology
Feasibility study done
– 40% CO2 capture using waste heat Brevik
– > 100m€ investment needed (+/- 30%)
– OPEX: > 40 €/t clinker
– CO2 from fertilizer industry + refinery will
be combined for shared storage
Next steps
– Evaluate to which extend Government of
Norway can finance CAPEX and OPEX to
avoid competitive out ruling of Norcem
– Evaluate how much HC can “bare” to
remain competitive
– 1½-2 years to finalize this phase

CCU with cyano bacteria and micro-algae
Modified bacteria to ethanol
Strategic Partnership with Joule Ltd
Large space

radiation
EU funding not
approved
Audi cooperation
partner with Joule
Pilot test possible
in combination
with micro-algae
Microalgae for fish & fowl feed
Sweden & Turkey
Microalgae are reacting positively to
the flue-gas of cement kilns
Algal biomass can be a base material
for fishmeal and animal feed
Market – interesting for cement-industry
Fishmeal

Concluding remarks
The cement industry set ambitious targets
on CO2 reduction in the CSI-Roadmap 2050
Carbon Capture requires intensive cooperation
in our industry and HeidelbergCement is
demonstrating leadership in this domain
In its operations worldwide HC is testing and
developing (commercial) use of CO2 from our
stacks applying various technologies
CO2 will become a valuable asset…..
