Callide Oxyfuel Project Update
19 June 2014
Global CCS Institute Japan Regional Members’ Meeting
• Purpose of the presentation is to provide an overview of the Callide
Oxyfuel Project and considers:
• Historical background of PF and oxy-combustion
• Callide Oxyfuel technology description (Oxyfuel Boiler and CO2 Capture
• Results of Oxy-fuel boiler and CO2 Capture trials
• Results of Storage assessments
• Lessons learned
Historical development of PF and oxy-combustion
The project, as formally established in 2008 has two broad goals, namely to:
• Demonstrate a complete and integrated process of oxy-fuel combustion of
pulverised coal within a National Electricity Market facility, incorporating
oxygen production, oxy-fuel combustion, CO2 processing and liquefaction, and
to assess CO2 transport and geological storage;
• Obtain detailed engineering design and costing data and operational
experience to under-pin the commercial development and deployment of new
and retrofit oxy-fuel boiler applications for electricity generation.
Configuration: 2 x 330 TPD ASUs, 30 MWe Oxyfuel boiler, 75 TPD CO2 Capture
Overall budget: CAPEX AU$180 million; OPEX $64 million
Operating Period: 2½ years
Project Goals, Cost and Operational Targets
CPU – Environmental performance
•Low pressure scrubbers utilise a
caustic soda wash to remove SO2
from the gas stream (< 10 ppm in
•Nitrous Oxide (NO) passes
through the LP scrubbers but is
largely converted to NO2 during
flue gas compression.
•Trace elements in the gas phase
are also effectively extracted from
the gas phase in the Low Pressure
section of the CPU.
•The principal gaseous emissions
from the CPU are CO2 and NO2.
Considerable work has been done
to characterise the behaviour of
NOx in the CPU.
CPU – Process condensates
Test data indicates:
• LP area (caustic wet scrubbers and filters) remove particulates, SOX, NO2 and a major
portion of trace elements
• NO is converted to NO2 in the compressor and a significant portion is removed with
the intercooler and aftercooler condensates as Nitric Acid.
• Almost all the Hg that has passed through the LP sections (as Hgo) is removed with the
Surat Basin Storage Tenements (South East Queensland)

• Establishment of the Project (structure, business systems, budgets, and
• Contract management
• Communications (with partners, Stakeholders and the Public)
• Identification and control of technical risks
• Operations and maintenance strategies and experience.
• Managing workplace health and safety, and the environment
• Transitioning of the power station culture and skill base from conventional
coal-fired power plant to more complex and multi-purpose facilities designed
to make electricity and capture CO2 and other emissions
• Enhancements that would be applied to the next scale up of the Oxyfuel and
CO2 capture technology
• Efficacy of the technology in general
1. The Callide Oxyfuel Project has been complex for 3 principal reasons:
• Large capital investment for a non-commercial demonstration, requiring a number of funding
agreements and equity.
• Engineer Procure Construct Manage (EPCM) for capital works involving a large number of
• First-of-a-kind project, operating in an electricity market.
2. Supporting R&D and publications:
• ANLEC (University Newcastle, Macquarie University)
• Global CCS Institute (Lessons Learned Report; Appraisal of CO2 storage sites in Surat Basin)
• NEDO & METI (IHI R&D)
• Air Liquide R&D
3. The Project has demonstrated over 6500 hours of oxyfuel boiler operation, routine mode changes
air-oxy mode, over 3200 hours of CO2 capture plant operation and capture rates exceeding 85%
4. Next step is to consolidate the learnings from Callide A and to apply these to new projects
