Abstract

This document contains worked examples of how to apply the accompanying “Guideline for Techno-Economic Assessment of CO2 Utilization” and “Guideline for Life Cycle Assessment of CO2 Utilization”. The Guidelines can be downloaded via http://hdl.handle.net/2027.42/145436. These worked examples are not intended to be a definitive TEA or LCA report on the process described, but are provided as supporting material to show how the TEA and LCA methodologies described in the guidelines can be specifically applied to tackle the issues surrounding CO2 utilization.

This document contains worked examples of how to apply the accompanying “Guideline for Techno- Economic Assessment of CO2 Utilization” and “Guideline for Life Cycle Assessment of CO2 Utilization”, hereafter referred to as "the TEA and LCA guidelines". These worked examples are not intended to be a definitive TEA or LCA report on the process described, but are provided as supporting material to show how the TEA and LCA methodologies described in the guidelines can be specifically applied to tackle the issues surrounding CO2 utilization. This example was constructed using data collected from a demonstration plant operated by Carbon8 Systems in Ontario, Canada, together with data obtained from the literature and from the ecoinvent database v3.4. As with the methanol worked example, the aim is not to prove whether the selected process is economically or environmentally viable or to make process alterations to make it so, but to clearly demonstrate how the proposed guidelines can be used to conduct a transparent TEA and LCA which can then be followed by others. The TEA example is provided in Part B, followed by the LCA example in Part C. In Part D, the reader will find a short example of how a TEA and LCA can be integrated. This integration is not an exhaustive example. As many aspects can be analyzed to produce combined indicators and many approaches to multi-criteria decision making applied. However, it is included here to provide a starting point and initial example of how integration can be carried out.
