The Global CO2 Initiative created the Excel templates located below to help practitioners conduct life cycle assessments (LCAs) and techno-economic assessments (TEAs) in alignment with the Initiative’s guidelines. The templates focus primarily on early-stage technology assessment, leading to them being more useful for describing hotspots and order-of-magnitude estimates rather than generating exact results. While the templates contain all the necessary steps for performing LCA and TEA, they may require significant adaptation for any particular project. The resources throughout this site can help with that process.
Download customized LCA and TEA templates: Aggregates, Algae, Chemicals, Concrete, or Direct Air Capture. Note that the inventory data contained in these templates represent very high-level guesses and estimates only; users must input data specific to their processes. Please see “Life Cycle and Techno-Economic Assessment Templates for Emerging Carbon Management Technologies” for further explanation of these templates.
The video below explains how to use the TEA template. A template and video for LCA can be found in the corresponding section of AssessCCUS.
CatCost is another cost estimation resource from the U.S. Department of Energy’s Energy Materials Network. This website offers a customizable spreadsheet as well as a web-based tool for cost estimation of pre-commercial catalysts, which are important for many carbon capture and utilization pathways.
The article “Techno-economic assessment of emerging CO2 electrolysis technologies” offers a customizable, Excel-based tool that can be used for early-stage TEA of CO2 electrolysis technologies.
The videos below cover TEA modeling or case studies. Information or methodologies contained within may provide useful guidance to those looking to perform TEA.
