Course paper / final thesis

Development of Molten Halide Salt Technologies for Low-Cost Large-Scale Energy Storage

Starting date

3. January 2022

Duration of contract

5-6 months


by appointment

Type of employment


Molten salt batteries (MSBs) and molten salt thermal energy storage (MSTES) are intriguing energy storage technologies with advantages of low-cost, large-capacity and long-lifespan. MSBs have gained great interest as large-scale electricity storage device, able to integrate the intermittent renewable energy technologies like wind and solar in to the grid, while MSTES has the commercial applications of more than 20 GWhe in concentrated solar power (CSP) plants. As one of the largest research institutions in the world in the development of molten salts for energy-related applications, DLR Institute of Engineering Thermodynamics is working on overcoming this challenge with several years of experience on the development of molten halogen salts for large-scale thermal energy and electricity storage. The first master thesis is a part of the EU-H2020 project SOSTICLE, two Na-Zn MSBs will be developed for demonstration. DLR is in charge of development of molten salt electrolytes for these MSBs. The second master thesis focuses on the development of the Chloride MSTES (next-generation MSTES). In Chloride MSTES, electrochemical technology will be employed for long-term corrosion control.

Your tasks:

1.      In-depth literature review on related thesis research topic,

2.      Experimental and simulation work on development of related molten salt technology,

3.      Adaption of the experimental test-rig for the related tests,

4.      Writing the thesis.

Your qualifications:

  • Master in Chemical/Process Engineering, Chemistry, Electrochemistry, Materials Science and Engineering, Energy Engineering, Mechanical Engineering or related.
  • A good experience in molten salts, thermal energy storage, liquid metals, batteries, thermodynamic simulation, and/or chemical analysis such as titration, ionic chromatography (IC) and gas analysis is preferred.

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
