Sustainability of energy technologies: what are the environmental, economic and social impacts? Focus on renewable fuels of non-organic origin

The sustainability of energy technologies is necessary in the context of establishing energy policies for the transition to a zero-emission energy system. Therefore, it is essential to define criteria and methods for assessing environmental, economic and social impacts. This session explores the basic principles of sustainability of energy technologies, presenting methodologies for environmental life cycle assessment (E-LCA) and social and economic impacts on a national and local scale. Case studies and preliminary results of ongoing projects with a focus on green hydrogen and biomethane will be presented. The session closes with a panel discussion on the sustainability of renewable fuels of nonbiological origin (e-fuels and hydrogen) where the views of legislators, research, and industry are presented on recent developments related to policies and measures aimed at large-scale development of technologies related to hydrogen and other energy carriers of nonbiological origin.
