Balancing Energy Security and Cost in a Renewable Europe
On Wednesday 12 November 2025 Chunzi Qu will hold a trial lecture on a prescribed topic and defend her thesis for the PhD degree at NHH.
The purpose of the thesis is to explore the renewable-intensive European energy system from three perspectives: improving energy security, increasing production stability, and minimizing total energy system costs.
The thesis comprises four studies.
The first study investigates the potential role of nuclear energy in reducing Europe’s reliance on metal imports within a renewable-intensive energy system, focusing on the perspective of energy security.
The second study evaluates the return on investment of two nuclear energy projects - conventional nuclear and small modular reactors (SMR) - and two wind energy projects - onshore and offshore wind power.
The third study incorporates the power grid and employs a stochastic optimization model to determine the cost thresholds at which the integration of SMR into the European energy system can lower total system costs.
The fourth study uses a stochastic optimization model, along with sensitivity analysis, to assess the cost and efficiency thresholds that define the competitiveness of incorporating hydrogen into the energy storage system.
