Sustainable energy for research facilities in Europe — •Johannes Hampp and Michael Düren — Center for international Development and Environmental Research, Justus-Liebig University Giessen

Energy imports from countries with abundant wind and solar resources are considered to take on a key role in the European energy transition. Wind and solar power can be converted to chemical energy carriers like hydrogen and then imported by ship or pipeline for subsequent conversion back to electricity and (waste) heat. Inherent to this supply chain are conversion losses, typically of factor 2-3 of the final electricity provided. A more efficient and economic solution is importing electricity directly using high voltage direct current (HVDC) lines.

We propose a pilot project which could be pushed by the European Scientific Community, e.g. lead by CERN, to overcome the barriers and to secure low-cost and sustainable energy supply for European research institutions. Historically, political and economic barriers hindered such projects, prominently DESERTEC 15 years ago. Recent projects like XLink's Morocco-UK-Link are demonstrating this idea's feasibility and opportunities. In our proposed project, electricity could be imported from renewables out of Algeria or Tunisia via undersea HVDC lines to e.g. southern France, where a suitable power network to CERN and other research centres already exists.

Using techno-economic modelling we provide insights on the infrastructure scale and economics of such a project. We investigate the influence of different demand cases and explore alternative options.
