Technical and economic alternatives for transitioning towards 100% renewable energy systems


28.09.2018 kl. 13.00 - 16.00


The energy sector faces a number of challenges, including security of supply, resource
availability, energy costs, access to energy, land use effects and implications for the
environment and climate. These energy sector challenges may be addressed through the
transition to high-renewable energy systems. This dissertation is based on the design of
this transition. The aim of this dissertation is to investigate how analyses of technical and
economic alternatives for energy systems and technologies can support the design of 100%
renewable energy systems. The scope is primarily technical and infrastructure aspects and
implications of the design of future energy systems in Europe towards the year 2050.

The analysis is divided into three: 1) the analysis of concrete technologies, 2) the analysis
of applying two types of cost estimation methods for feasibility evaluations and 3) the
development of strategies for designing 100% renewable energy systems for Germany in
the year 2050.

The dissertation concludes that 100% renewable energy systems are feasible and will
address the key challenges in the energy sector. These 100% renewable energy systems
cannot be designed from single technologies or solutions but require a full energy system
perspective. The strategies designed in this dissertation indicate that energy system costs
are comparable to the costs of fossil fuel alternatives.
