Postdoc in Synthesis and Solid-State storage of Ammonia

Technical University of Denmark (DTU)

2800 Kgs. Lyngby, Denmark

Department of Energy Conversion and Storage at the Technical University of Denmark (DTU Energy) invites applications for a two-year experimental – modeling postdoc position to work on the development of ammonia synthesis and storage via sorption into solid-material.

This postdoc position is open in the frame of the ARENHA European project with 11 partners. Driven by the need to drastically increase the capacity of energy storage while increasing the Power to X to Power efficiency, the key objective of ARENHA is to demonstrate the viability of ammonia as key energy carrier for stationary storage of excess renewable energy. At DTU Energy, the postdoc tasks are to develop new sorbent materials and beds / tanks for modified Haber-Bosch synthesis of ammonia and its solid-state storage. A first focus of the work is to synthesize and characterize new mixed cation halides with properties suitable for the working parameters of the modified Haber-Bosch synthesis (lower pressure and temperature than conventional method), and with the parameters for safe solid-state ammonia storage. The composition of the materials to be studied will be first determined by Density Functional

Calculation performed prior to this experimental work. A second focus of the work is to optimize the design of the sorbent Haber-Bosch bed and solid-sate storage tank using a simulation tool already developed at DTU Energy. At the final stage, a small-scale prototype of the bed and tank will be constructed and tested, and the implementation of their full-scale counterpart in the ARHENA prototype supervised. The research project will be conducted as a collaboration between the Section for Imaging and Structural Analysis (ISA) and the Section for Atomic Scale Modelling (ASM). The experimental work is done in the framework of ISA and the achieved results are related to the modelling activities that are performed in ASM. The research environment is international, inspiring and dynamic.

Responsibilities and tasks
The successful candidate will work in close collaboration with the experimental and simulation groups to discover the optimal materials and bed / tank design for the synthesis and storage of ammonia.

Main duties of the position include:

  • Synthesis of mixed cation halides
  • Structural and ammonia sorption properties characterization
  • Simulation using COMSOL software and existing model of optimized bed / tank design.
  • Construction and test of small-scale bed / tank prototype.

Candidates should have a PhD degree in experimental physics, chemistry, materials science or equivalent. The core skills for the project are:
  • Experience in COMSOL modeling of fluid dynamics, heat and mass transfer.
  • Experience in characterization of sorption material with Sievert’s method.
  • Experience in material synthesis using mechano-chemistry.
  • Excellent communication skills in English (both written and verbal)
  • Ability to work independently and take responsibility for progress and quality of projects
  • Ability to work in an international team environment
  • Moreover, the successful candidate is:
  • Highly motivated and enthusiastic about the research topic.
  • Able to work in an organized fashion, document and disseminate scientific results such as writing results in reports and publications.
  • Able to work with diverse colleagues with working on theory and experiments

The assessment of the applicants will be made by: Senior Researcher Didier Blanchard and Head of Section Luise Theil Kuhn
