Templates and Videos


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.

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.

The Techonomics section of Activate’s website also contains models and videos that can help with early-stage cost modeling.

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.
