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
Une promotion ciblée de l'innovation pour la transition énergétique
Comment les innovations naissent-elles et comment peuvent-elles être encouragées de façon ciblée en vue de la transition énergétique? Michael Weinold, chercheur au PSI, a tenté de répondre à cette question en prenant pour exemple les lampes LED.
Neutralité carbone: inclure les matières premières
Un nouveau modèle de calcul du PSI visualise les interactions complexes entre technologie, besoins en matières premières critiques et impacts environnementaux nécessaires à la transition du système énergétique vers «zéro émission nette» de gaz à effet de serre.
Decarbonizing Building Construction
The buildings we live and work in are changing – becoming smarter, more efficient, and powered by cleaner energy. But while we’ve made strides in reducing operational emissions, there’s a hidden carbon footprint that remains largely overlooked: the emissions locked into the materials themselves.
