The interdivisional PSI Laboratory for Energy Systems Analysis conducts analytical research on diverse energy technologies and systems.
LEA is a cross-center laboratory bridging the Centers for Nuclear Engineering and Sciences (NES) and Energy and Environment (CEE). It unites specific analytical research on diverse energy technologies and systems, including nuclear, fossil and (modern) renewables. Taking an holistic and interdisciplinary approach, LEA develops models, analysis and tools to support decision makers and researchers to address complex and systemic challenges in the broad field of energy. LEA includes the groups Technology Assessment, Energy Economics, Risk and Human Reliability, and the Chair of Energy Systems Analysis at the Department of Mechanical and Process Engineering (D-MAVT) of ETH Zurich. The link between LEA and D-MAVT was established in 2022 by the appointment of the LEA Head, Prof. Dr. Russell McKenna.
The LEA areas of activities fall into three main areas:
Lab News & Scientific Highlights
Die Wettbewerbsfähigkeit klimafreundlicher Kraftstoffe hängt vom Standort ab
Produktionsstandort, Finanzierung und Innovation bestimmen die Wettbewerbsfähigkeit klimafreundlicher Kraftstoffe.
Hydrogen and the energy puzzle
What is the role of low-carbon molecules on the road to climate neutrality?
Ein umfassendes Energiesystemmodell für die Schweiz
Energiesysteme stehen vor komplexen, langfristigen Herausforderungen, die mit einem hohen Mass an Unsicherheit behaftet sind. Das STEM-Energiesystemmodell der Gruppe Energiewirtschaft am PSI ist zu einem wichtigen Instrument geworden, um diese Herausforderungen zu erforschen und die Entscheidungsfindung zu unterstützen.
