Master Thesis - Comparative LCA of hydrogen transport with DME, Ammonia, and Methanol for securing Germany`s steel industry

titel

As demand for hydrogen grows across sectors, the need for efficient transportation methods becomes paramount. While pipelines have traditionally been favored for transporting high-purity hydrogen, alternative methods present compelling options, particularly for regions where pipeline infrastructure is lacking or economically unfeasible. This thesis explores chemical hydrogen carriers, specifically dimethyl ether (DME), ammonia, and methanol, targeting scenarios where high purity is not a strict requirement. By examining the potential of different transportation chains alongside conventional pipeline systems, this study seeks to identify the most promising options for hydrogen transportation in Germany, focusing primarily on environmental impacts. This work builds upon a previous master thesis that defined a case study in Germany for hydrogen transportation with low purity requirements (e.g., for steel production) and conducted a cost analysis of different hydrogen supply chains.

Your Job:

The primary objective of this thesis is to assess the environmental impacts of DME, ammonia, and methanol as hydrogen carriers compared to a non-chemical reference system for transporting hydrogen within Germany, focusing on scenarios where high purity is not essential. Specific research objectives include:

  • Conducting a comprehensive literature review to understand the current state of research on hydrogen transportation methods, with a focus on chemical carriers
  • Gathering information from other projects at Forschungszentrum Jülich with similar focus to inform and refine the scope of the Life Cycle Assessment (LCA)
  • Performing an LCA to quantify and compare the environmental impacts of DME, ammonia, methanol, and selected other hydrogen transportation methods, considering factors such as greenhouse gas emissions, resource depletion, and human toxicity


By addressing these objectives, this research aims to contribute to the ongoing discourse on hydrogen transportation and facilitate informed decision-making towards achieving Germany`s energy transition goals. The findings will provide valuable insights into the environmental trade-offs associated with different hydrogen transportation methods, supporting the development of sustainable energy systems in Germany and beyond.

Your Profile:

  • Technical master studies (mechanical engineering, electrical engineering, construction engineering) or information technology study background with high interest in technical applications (computer science, computational linguistics)
  • Experience in LCA
  • Fluent written and spoken English
