|The CO2CRC Otway Project - Leading CO2 storage research (2011)
The CO2CRC Otway Project is Australia’s first demonstration of the deep geological storage or geosequestration of carbon dioxide (CO2), the most common man-made greenhouse gas. Geological storage of CO2, as part of carbon capture and storage (CCS), has the potential to reduce greenhouse gas emissions from large industrial sources such as power stations by up to 90 per cent.
|Carbon capture in action (2010)
CO2CRC, is conducting research into new ways of capturing carbon dioxide from power stations. This video explains promising technologies and shows the research in action in Australian industrial demonstration projects.
|Chocolate CCS (2012)
The type of rocks we need for storing carbon dioxide have both space for the carbon dioxide (porosity), and pathways for the carbon dioxide to move through (permeability). In this experiment we look at how a fluid cannot move through a rock with holes but no pathways...
|Hands on CCS (2011)
Learning about carbon capture and storage at Warrnambool College, students captured carbon dioxide, tested water samples for carbon dioxide, examined the type of rocks that can store carbon dioxide and investigated the measurements taken from deep underground when a new well was drilled.

This video shows the installation of a 30 metre assembly of sophisticated pressure, temperature and sampling instruments at the CO2CRC Otway Project in February 2011 over about an hour.

|The CO2CRC Otway Project (2008)
The CO2CRC Otway Project in Victoria is Australia’s first demonstration of deep geological storage of carbon dioxide, with over 65,000 tonnes safely stored since April 2008. The successful project includes a comprehensive monitoring program.
|The CO2CRC Otway Project - CRC Awards
for Excellence in Innovation (2008)
In 2008 the CO2CRC Otway Project was awarded a CRC Association Award for Excellence in Innovation. This video was screened at the awards ceremony and includes footage from the opening of the project in April 2008.
|CO2 residual trapping simulation
Residual gas trapping occurs when a small amount of CO2 becomes disconnected or 'snaps off' from the CO2 plume as the CO2 moves through the porous rock. The CO2 is stored in the pores in tiny bubbles, trapped by surface tension. The CO2 can't move out of the pore space and remains fixed underground.
Carbon dioxide can be separated from other gases using a membrane. Pressure difference across the membrane drives the separation. Membranes are commonly used in applications such as water purification and are being developed for large-scale carbon dioxide separation with the potential to reduce equipment size and eliminate the need for solvents.
|Otway schematic diagram - Stage 2
In Stage 2 of the CO2CRC Otway Project, residual trapping of carbon dioxide injected into a saline formation was measured.
|Otway schematic diagram - Stage 1
In Stage 1 of the CO2CRC Otway Project, over 65,000 tonnes of carbon dioxide-rich gas was stored in a depleted gas reservoir.
|Carbon capture and storage diagram
Carbon capture and storage is a way of collecting and storing carbon dioxide so that it does not enter the atmosphere.
|Absorption and desorption
One way of capturing carbon dioxide is to absorb it into a liquid.
|Adsorption and desorption
Solid materials can attract carbon dioxide to their surface – a process called adsorption.
The cyclical process of adsorption and desorption for carbon dioxide capture involves several stages and can use two or three "beds" for efficiency.
Membranes can be used in conjunction with a liquid to separate carbon dioxide from other gases.
