DF 68: 68th LCA Discussion Forum

DF 68 — LCA of key technologies for future electricity supply

Discussion forum on Life Cycle Assessment
Monday, 16 April 2018, ETH Zürich, Alumni Pavillon

In the recent past, many countries increased the share of renewable energy sources in the electricity mix substantially and will continue to do so in the future. Intermittingly producing technologies such as photovoltaic or wind power plants are a challenge for electric utilities and ask for new concepts regarding grid operation, dispatching and storage. This forum will cover the full range from life cycle assessments of specific components namely photovoltaic panels, geothermal power stations and battery storage facilities to promising concepts of system integration in electricity networks such as smart grids.

Main focus will be on the future environmental performance of these key technologies, on the main environmental challenges faced and on the way how electric utilities will facilitate the energy turnaround to comply with the ambitious target of the Paris Agreement and the due phase out of nuclear power. This forum aims at facilitating discussions among different domain experts in view of creating new ideas.

This forum is targeted to technical experts in the electricity sector and LCA practitioners.
