Development of a model for evaluating the sustainability value of energy technologies and its application to technology development

Research outline

As global efforts to achieve the SDGs goals progress, so-called ESG investment, in which investment targets are determined in consideration of environmental and social impacts, corporate governance, and other factors, is gaining momentum, and the importance of evaluating the sustainability value of energy technologies is growing even more. Therefore, this study aims to establish a sustainability value evaluation model for energy technology from the perspective of ESG investment and new national wealth indices and to link this model to the development of energy technology and its application in social implementation. To this end, this study aims to establish a sustainability value assessment model for energy technologies by labeling multiple energy technologies based on HS codes considering their life cycles, calculating social, economic, and environmental values by applying the social LCA and environmental LCA methods, and using the expressed selection method to work on the construction of an evaluation model to show the impact of energy technologies on various types of capital (natural capital, produced capital, and human capital) at shadow prices by using ESG indexing and the inclusive wealth index, and on the social implementation of the evaluation model.

Research originality

Despite the abundance of LCA on energy technologies, most have concentrated solely on greenhouse gas emissions. To date, there has been a lack of research that undertakes a comprehensive evaluation of the environmental, social, and economic impacts. The model to be established in this study will not only provide a comprehensive assessment of LCA but also enable the evaluation of the calculated impact assessment results as a measure of sustainability from an Environmental, Social, and Governance (ESG) investment perspective and in relation to a new national wealth index. As a result, the findings obtained through this research hold significant academic and societal relevance.

Expected results and outcomes of the collaboration

This research module aims to construct a sustainability value evaluation model for energy technology, which is of paramount academic importance. The objective is to develop initiatives that lead to social implementation through collaboration with local communities, companies, and demonstration tests. The model, which evaluates sustainability from the perspective of a new national wealth index, is intended to be linked to implementation in government policies related to energy technology. The model, which evaluates the sustainability of energy technology from the Environmental, Social, and Governance (ESG) investment perspective, will be applied to new energy technologies such as the Direct Air Capture and Utilization Unit (DAC-U) currently under development at TUAT and will be utilized in the advancement of energy technology through collaboration with companies. The ultimate goal is to apply the model to new energy technologies, such as the DAC-U, and to facilitate social implementation through its use in energy technology development in partnership with companies.
