Climate change is one of the biggest challenges of our time. The energy system, while being one of the main pillars of modern societies, is also one of the largest contributors to greenhouse gas emissions. The Green Transition toward sustainable, resilient, and affordable energy supply is pursued with a mix of solutions, such as:

• deploying renewable energy sources (Christine Brandstätt)
• accelerating hydrogen and green fuels (Johannes Giehl)
• capturing CO₂ for utilization and storage (Manuel Llorca)
• and potentially nuclear power (Jens Weibezahn)

Each of these are associated with their own economic, societal, regulatory, and technological issues to ensure their implementation and that businesses can transition smoothly.

In this talk, a group of four researchers from the Copenhagen School of Energy Infrastructure (CSEI) at the Department of Economics will discuss some key aspects related to these solutions.

Christine Brandstätt is an Assistant Professor with the Copenhagen School of Energy Infrastructure (CSEI) at CBS and currently also a visiting fellow with the Oxford Institute for Energy Studies. Her research mainly focusses on the integration of renewable energies in energy markets and network regulation. It analyses the interactions of different regulatory and market designs within energy systems. Over more than 10 years she has participated in and led several research projects in this field.

Johannes Giehl is a Postdoc at the Copenhagen School of Energy Infrastructure (CSEI) at CBS. His research in energy system transformation focuses on renewable hydrogen and energy infrastructure development, energy economics and sector coupling business models. He is currently involved in two research projects on the characteristics of optimal production of hydrogen, ammonia, and other electrofuels (https://csei.eu/nord_h2ub/) and the market potential for hydrogen in the Nordics (https://csei.eu/ptxmarkets/).

Manuel Llorca is an Assistant Professor at the Copenhagen School of Energy Infrastructure (CSEI) of CBS. His research interest includes economic performance and regulation of energy networks, energy poverty, and energy efficiency and rebound effects, among other themes. Currently, he is coordinating a research project on the Public Acceptance of Carbon Capture, Utilisation, and Storage (PAoCCUS) in Denmark funded by Danmarks Innovationsfond (https://inno-ccus.dk/public-acceptance-of-ccus).

Jens Weibezahn is an Assistant Professor and Marie Skłodowska-Curie Fellow with the Copenhagen School of Energy Infrastructure (CSEI) at CBS. His research mainly focuses on flexibility options, sector integration, decentralization, and planning and market design in energy systems using – amongst other methods – open-source energy system models. He is currently involved in two research projects on energy sharing and energy communities (NRGcitizens) and on Nordic hydrogen valleys as energy hubs (Nord_H2ub).
