In the light of shrinking fossil energy reserves and the international climate protection goals a further massive expansion of renewable energies (wind turbines and photovoltaic power plants in particular) is considered as indispensable. Their fluctuating occurrence requires further developed solutions of energy storage on an industrial scale. For this purpose the conversion of electricity to hydrogen by means of electrolysis, also referred to as power to gas, offers a promising technical solution by which reductions of CO2 in further energy sectors such as the transport sector can be achieved at the same time. Thereby the usage of hydrogen is very promising to store fluctuating renewable energy
At the IEK-3 international energy concepts are developed to convert surplus energy from intermittent renewable energy sources into hydrogen and transfer it to other energy sectors like mobility or industry. In this regard an international hydrogen infrastructure is of vital significance. Due to regions of energy excess on the one hand and regions with a higher energy demand, a worldwide solution is required to achieve an economically reasonable usage of hydrogen..
Within the scope of this thesis the worldwide existing and planned projects for the generation, the transport and the distribution of hydrogen are supposed to be identified and categorized according to the planned or already implemented models. Here the main focus is on the possible transport modes via pipeline or ship. The objective of the thesis is a concept to assess the infrastructure systems with regard to techno‑economic aspects. The following tasks are to be dealt with in the course of a master thesis:
Research of worldwide existing and planned projects of hydrogen provision, transmission and distribution grids in particular
Analysis of the respective supply structure and categorization of the projects with regard to the used models and their characteristics
Determination of grid stakeholders (electricity and gas grids)
Comparison of the respective politically and geographically determining factors of hydrogen provision
Working out a concept of technological and economical assessment, for example concerning costs, subsidies and economies of scale
