Identification of Hazards and Environmental Impact Assessment for an Integrated Approach to Emerging risks of CO2 Capture Installations

Abstract

New and intensified technologies are being defined within the field of Carbon Capture and Sequestration (CCS) and the uptake is set to increase dramatically. This contribution focuses on three representative installations for CCS capture, whose safety and environmental issues might potentially be underestimated based on their presence in other industrial fields, but with different scales and uses. A simplified Life Cycle Assessment (LCA) and the new hazard identification technique denominated DyPASI (Dynamic Procedure for Atypical Scenarios Identification) were used to identify respectively environmental impact and atypical accident scenarios and add a useful dimension to risk information that can particularly help in determining the best technological options.

‘End to end’ linkage structure for integrated impact assessment of infrastructure networks under natural hazards

“…Even though these models are developed for their specific purposes, it is fundamental to link these models and increase their uptake in hazard-impact assessments. However, at present, there is no structured framework to link different models together and there is a need to understand what is needed in the flow from one model to the next, to facilitate integrated impact assessment of infrastructure networks [7].…”

Climate Change Mitigation Technologies: Carbon Capture and Storage in the Brazilian scenario

“…However, CCS may results in environmental damages, as CO2 leakage, thus to achieve the mitigation targets, it is important to assess this risk (Widdicombe, Blackford, and Spicer, 2013;Wood, Glasson, and Becker, 2006;Tzanidakis et al, 2013;Raza et al, 2016;Paltrinieri et al, 2013;Onyebuchi, et al, 2018;Noothout, et al,2014;Murray et al,2017;Mitchell, 1997;Msnuilova, Subsiri, and Wilson, 2009;Mikunda and Dixon, 2017). Besides, so far, there is no specific legislation for those activities in Brazil (Quintella et al, 2011;Rochedo et al, 2016;Rockett, 2011;Román, 2011;Román and Schott, 2011;Sathre et al, 2012;Machado, Rockett and Ketzer, 2013;Moreira et al, 2014).…”

Qualitative risk assessment for using a mature oil field as a pilot experiment of CO<SUB align="right">2 geological storage in Brazil

“…The risks of future carbon supply has been strongly debated, as is the viability of alternative energy sources, which do not seem to be able to maintain viability without government financial support (Wu et al, 2013). CCS can represent a 'technological bridge' between mitigation of climate change and sustainable energy chain, being an important option against the increase of GHG concentration and, at the same time, allowing the continued use of fossil fuels (Paltrinieri et al, 2013). The CCS life cycle includes steps ranging from the capture of an anthropogenic source of emissions followed by separation, dehydration, compression, transport to storage location and the confinement itself.…”
