Abstract: Greenhouse gas emissions from industrial processes, such as cement manufacturing or steel production, in Australia accounts for more than 40 Mt CO2-e per annum, representing close to 20% of Australia’s potentially sequesterable emissions. Further, the emissions from these processes are highly concentrated in CO2 compared to the emissions from power generation. It is not clear if these higher concentrated gases may provide low cost options for demonstrating CO2 capture or if this benefit will be lost due to the smaller total volume of CO2 emissions of most industrial processes. Nevertheless, this sector of the economy requires further analysis. This paper will provide an overview of the emissions from Australian cement sector including both the emissions from the chemical process itself, as well as the associated emissions from energy use within those processes. Specific attention will be focused on the Australian cement industry. While CCS involves the integrated part of capture, transport and storage, the focus of this paper is on the capture side and will illustrate CCS options for the cement industry.

Abstract: This paper presents the results of an evaluation of the longer term impact of a series of workshops conducted in four Australian cities which sought to engage representatives of the Australian public in discussions about climate change and low emission energy options. These workshops were designed to explore the public’s awareness and acceptance of the various low emissions energy technologies, including carbon dioxide capture and storage (CCS), and to assess whether a large group workshop format was an effective means of affecting change in awareness and acceptance of the various energy technologies. Initial results of these workshops, presented at the International Conference on Greenhouse Gas Technologies (GHGT) in 2008, found that the workshop was indeed effective. Results from an online survey conducted in October 2009 with 95 participants of the original workshops indicate that over the longer term awareness remains at a higher level than prior to workshop attendance, while changes in participants’ attitudes were not sustained over time. However, the results of 22 follow-up in-depth interviews conducted in November and December 2009 found that many workshop participants reported a change in their awareness of and preference for the energy technologies, and that they pro-actively spoke with others and sought further information regarding the technologies and their place in a low carbon economy. While wind and solar energy were clearly favored, carbon mitigation was generally recognized as a complex issue requiring a portfolio of energy solutions. Building trust in the range of energy solutions, including carbon capture and storage, will require ongoing engagement and dialogue with members of the public. [Copyright &y& Elsevier]
