Demonstration in Australia
Decreasing carbon dioxide emissions from major stationary sources is firmly on the Australian agenda and carbon capture and storage (CCS) is seen as a vital part of the national mitigation portfolio. There are now a number of CCS demonstration projects underway or planned and several major commercial CCS projects proposed for Australia.
Callide Oxyfuel Project, Queensland
This demonstration project involves conversion of an existing 30MW unit at Callide A (currently underway) with power generation and capture of CO2 commencing in 2010. The second stage of the project will involve the injection and storage of about 100,000 tonnes of captured CO2 in saline aquifers or depleted oil/gas fields over about five years, commencing in 2011. This project is expected to cost A$206 million. The project is a collaboration between partners CS Energy, IHI, Schlumberger, Mitsui &Co, J-Power, and Xstrata, with extra funding from ACA and the Australian and Queensland Governments.

CO2CRC Otway Project, Victoria
This is Australia’s most advanced storage demonstration project. Injection of CO2 from a nearby gas well initially into a depleted gas field at a depth of 2km began in April 2008 at a rate of about 120 tpd, with an injection target of 100,000 tonnes of CO2 over two years. A major program of monitoring and verification has been implemented. The A$40 million Project, which is supported by 15 companies and 7 government agencies, involves researchers from Australia, New Zealand, Canada, Korea and the USA. CO2CRC Pilot Project Ltd, the operating company, includes AngloCoal, BHP Billiton, BP, Chevron, Schlumberger, Shell, RioTinto Solid Energy, Woodside and Xstrata. Additional financial support is provided by the Australian Government (RET), the Victorian Government and the US DOE.

Coolimba Power Project, Western Australia
Construction of Aviva Corporation Ltd’s 2x200MW coal-fired base-load power stations should begin in the second half of 2009 and be completed by 2012. The plant will be built ready for conversion to CO2 capture. Sequestration sites are being identified for the storage of about 3Mtpa of CO2 for up to 30 years with the involvement of CO2CRC and ARC Energy.

FuturGas Project, South Australia
Hybrid Energy Australia is researching the development of the carbon dioxide storage component of the FuturGas Project – an energy conversion development involving the gasification of lignite to syngas for the production of synfuels. It is proposed that the CO2 captured post-gasification will be stored in the Otway Basin to the south of the lignite resources. A feasibility study will be completed in 2010. It is estimated to begin by 2016.

Gorgon Project, Western Australia
Chevron (operator), Shell and Exxon are planning a major sequestration project linked to the Gorgon LNG Project. The separated CO2 will be injected under Barrow Island to a depth of about 2.3km, with injection of 3.3 million tonnes of CO2 per year. A total of 125 million tonnes will be injected over the life of the project, which is planned to commence around 2009. A data well has been drilled and a major study of the subsurface is underway.

Hazelwood and Loy Yang PCC Projects, Victoria
These projects involve and the retrofitting of pilot scale post combustion CO2 capture plant. Work is underway on a CO2CRC facility at Hazelwood that will capture and chemically sequester CO2 at a rate of 10,000-20,000 tpa of CO2 with capture to commence late 2008. A CSIRO mobile pilot PCC facility has begun operation at Loy Yang and will capture around 1,000 tpa of CO2. Partners in these projects include International Power, Loy Yang Power, CO2CRC, CSIRO and Process Group with funding from the Victorian Government (ETIS).

Mulgrave Pre-combustion Capture Project, Victoria
CO2 emissions will be captured from HRL’s research gasifier in Mulgrave in a pilot scale capture project by CO2CRC. The capture technologies will be evaluated to identify which are the most cost effective for use in a coal gasification power plant. Partners include CO2CRC and HRL with funding from the Victorian Government (ETIS)

Monash CTL Project, Victoria
This proposed project is designed to exploit the source-sink match involving the brown coal resource of the Latrobe Valley and the CO2 storage potential of the off-shore Gippsland Basin. It involves gasification of brown coal to produce syngas, with a shift reaction and extraction of excess CO2 before the syngas is converted into a range of liquid products. The CO2 would be compressed for transport via pipeline to a suitable storage site. A full scale plant (70,000 barrels per day) is projected to take ten years from conception to full production and would require injection and storage of approximately 15 million tpa of CO2. Monash Energy is a joint development of Anglo American and Shell Gas and Power

Moomba Carbon Storage Project, South Australia
This project is currently at the early feasibility stage, with the objective of establishing a regional carbon storage hub in the Cooper Basin. The proposed demonstration phase, commencing in 2010, will involve the capture of CO2 from existing gas processing facilities and injecting one million tonnes of CO2 to re-pressurise oil reservoirs for enhanced oil recovery. Partners in this project include Santos and Origin.

Munmorah PCC Project, New South Wales
This research scale pilot project will investigate the post combustion capture (PCC) ammonia absorption process, and the ability to adapt it to suit Australian conditions. Capture of up to 3000 tonnes of CO2 for the pilot phase, using a mobile rig, is expected to begin by late 2008. Partners involved in this project are Delta Electricity, CSIRO and the ACA.

ZeroGen Project, Queensland
The Queensland Government, ACA and industry partners Shell Development and Zerogen propose a two stage coal gasification and CCS project “ZeroGen Mark II”. Stage 1 (demonstration) will be a 80 MW net plant located near Rockhampton and is expected to be operational by 2012. The CO2 will be captured and transported approximately 220km by pipeline for storage in the Denison Trough. Stage 2, a 300 MW net coal gasification plant, is proposed to come online by 2017.
