Carbon dioxide Capture and Storage
03/07/2014 Chris Hendriks 8
Carbon dioxide (CO2) capture and storage (CCS) is a process
consisting of the separation of CO2 from industrial and
energy-related sources, transport to a storage location and
long-term isolation from the atmosphere. IPCC Special Report on Carbon Dioxide Capture and Storage, 2005

How to reduce energy use
> Heat integration in the plant – Low-temperature heat required: do not use fuel but heat from low-
pressure section of steam turbine > Waste heat from other industrial processes > Improving capture process
– Better solvents (higher capacity, lower temperatures)
> Current “state-of-the-art” post-combustion capture reduces energy use to 20-30% (efficiency penalty of about 8-10%)

Pipelines
> High upfront investments > Not flexible (in route and
capacity) > Long lead-time > Low specific transport costs
> Low investments > Flexible (in route and
capacity) > Short lead-time > High specific transport costs

Residual trapping: CO2 is trapped in tiny rock pores and cannot move
CO2 is trapped in tiny roc
Dissolution trapping: CO2 dissolves into surrounding salt water
Mineral trapping: CO2-rich water sinks to the bottom of the reservoir
and reacts to form minerals
Stratigraphic and structural barriers: CO2 movement is blocked by
impermeable caprocks

Themes requiring solutions (1)
> Legal/Regulatory – Transboundary shipment of CO2
– Liability of stored CO2
– Recognition of stored CO2 from biomass in ETS – CO2 composition standards
> Economics – Cost reduction – Demonstrations required – Impact of changing power markets – Financing systems

Themes requiring solutions (2)
> Public – Role of CCS – Safety aspects – Compensation scheme for local public
> Technical – Monitoring systems for stored CO2
– Reducing energy use – Industrial sources and combining smaller sources
> Organisational – Setting up infrastructure – Let the system work: capture – transport - storage

Typical topics Ecofys on CCS
> Environmental performance of CCS
> Techno-economic studies
> Stakeholder interaction
> Business case development
> Policy development
> Economic value of CCS (market share, added value, employment)

Five ‘issues’ to address to improve CCS deployment
1. Role of CCS in abating CO2 emissions
2. Research and development to improve performance of CCS
and improve stakeholder capacity building
3. Improvement of economic conditions to accelerate the deployment of CCS
4. Establish short, effective and transparent procedures to
develop and implement CCS projects
5. CCS project developers need sufficient certainty about long-term spatial planning, long-term political commitment and economic viability

Conclusion
> For 2˚C target: CCS is required, including bioCCS
> CCS: technology is available; policy context not
> CCS is important for industry
> CCS important for non-OECD countries
> Current progress on CCS mainly outside Europe
> Main challenges:
– Economics
– R&D and demonstration
– Public acceptance
– Complex organisation -> focus on clusters of industry/power
