Background

The evaluation and analysis of sustainable value chains requires the application of interdisciplinary research approaches. These approaches combine economic, ecological, technical and scientific, legal and social aspects. As a result, value chains can be analyzed in their breadth and depth on a system-wide and process-specific basis.

Contents of the work

Power-to-X (PtX) technologies, especially those based on green hydrogen, are crucial for the defossilisation of sectors that are difficult to electrify, such as aviation. As part of the ‘Refineries for Future’ project, various project partners are collecting concrete process data and models for Ptx-based refineries – this work uses these exclusive data sets to generate scientifically sound and practical insights.

Conducting a techno-economic analysis (TEA) for a PtX refinery using Germany as an example market, with a focus on:

•The role of green hydrogen in the value chain (e.g. direct use vs. further processing into e-kerosene).

•Cost optimisation (CAPEX/OPEX) using project data – including sensitivity analyses on electricity prices, CO₂ availability and economies of scale.

•Derivation of break-even scenarios for the German market compared to fossil alternatives.

 Requirements

This thesis is aimed at students of economics, environmental and chemical engineering, mechanical engineering and similar courses. A systematic and results-oriented approach is a prerequisite for being awarded the thesis. An interest in cost accounting and process technology is an advantage. The thesis is particularly suitable for determined and systematic students with prior knowledge of plant design and Microsoft Excel. Please enclose a current transcript of your grades and your CV with your application.
