Why store CO2?

The safe and secure long-term atmospheric removal of the carbon dioxide (CO2) captured from coal-fired power stations and other major emission sources is paramount to effectively reducing greenhouse gas emissions in NSW.

The main CO2 storage options currently being investigated include underground geological storage in porous rock formations, algal and bio-sequestration, ocean storage and mineral carbonation.

Apart from the conventional geological storage of CO2 which the NSW Government is undertaking through the NSW CO2 Storage Assessment Program, NSW is actively looking at non-conventional forms of CO2 storage as part of developing a portfolio of storage options to meet differing needs throughout the State.

Project: Permanent Large-scale CO2 Storage by Mineral Carbonation in NSW

The challenge:

Reducing greenhouse gas emissions from entering the atmosphere by developing novel ways to safely and securely store CO2.

The action:

Coal Innovation NSW funded Mineral Carbonation International to develop and optimise a promising method of permanently storing CO2 as well as utilise it for building materials.

Grant amount:

Up to $3.04 million (EOI Round 2009).

The project:

Mineral Carbonation International Pty Ltd (MCi), a joint venture between the Greenmag Group, Newcastle University and Orica, received grant funding of up to $3.04 million from the Fund to develop and optimise a promising method of utilising CO2.

The Mineral Carbonation process mimics and accelerates the Earth’s own carbon sink mechanism process, whereby CO2 is captured in mineral deposits and then stored in rocks. These solid products can be used in various applications including building materials.

The project is being conducted by a multi-disciplinary team of researchers, and chemical and industrial engineers and is being co-funded by Orica and the Commonwealth Government. This cutting-edge project could position NSW as a world leader in the building and operation of mineral carbonation plants.

Currently the research team has built and commissioned a batch plant and a semi continuous plant at the University of Newcastle. All milestones have been met and the research is on track to be completed successfully.
