Novel Approaches to CO2 Utilization III
Wednesday, November 18, 2020 - 8:45am to 9:00am
LCA is uniquely suited to employ in the analysis of CO2 utilization technologies because of the methodical approach that forces a cradle-to-grave understanding of the system. It is not uncommon to see CO2 utilization analyses that focus mainly on the utilization technology and apply a simplified approach to the upstream CO2 source. We contend that a robust treatment of the upstream CO2 source is imperative in any CO2 utilization LCA, because of the important link between the source of the CO2 and the use of the CO2 in the overall environmental impact. This holistic view is necessary to understand the net benefits of the entire system, not just a subset. Conducting LCA guidance work early is important in the development of these emerging technologies, because it allows time to implement change while technologies are still nascent. Additionally, U.S. Department of Energy (DOE) and the federal government is increasingly requiring LCA as part of funding for primary research and tax incentives like â45Qâ for CO2 capture, utilization, and storage projects (H.R. 1892, 2018).
In the interest of supporting the creation of useful and consistent LCAs of CO2 utilization projects, the DOE National Energy Technology Laboratory has developed a CO2 utilization LCA toolkit. The primary audience for the toolkit is the group of principal investigators that have been awarded a grant through a DOE Carbon Use and Reuse funding opportunity announcement. However, we believe that there is wider application beyond those grant recipients. The toolkit comprises a guidance document, reporting templates, openLCA contribution analysis tools, LCI data, and subject matter expertise. The guidance document should be considered as a companion to the requirements established in ISO 14040/14044, providing specific guidance on methodological issues for scoping and completing the LCA. The guidance, data, and tools are publicly available and free. This presentation will provide an overview of each part of this first-of-a-kind toolkit, itâs utility to the LCA community, and value in assessing emerging technologies.
