Postdoc Position on Hydrogen Liquefaction using Magnetocalorics

Updated: about 2 months ago
Deadline: 28 Feb 2023

Do you want to help develop innovative and environmentally friendly energy technologies based new cooling technologies to enable Power-to-X?
As part of a large EU funded project, we will develop a cryogenic cooler based on the magnetocaloric effect to liquify hydrogen for transportation purposes. The consortium of 14 partners from 9 different countries will develop magnetocaloric materials and apply them to a new prototype capable of liquifying hydrogen starting from liquid nitrogen temperature. The consortium will also consider hydrogen safety and the roadmap for rolling out hydrogen as a major element of the future energy system.

This postdoc position will focus on modelling the magnetocaloric liquefaction device using an existing model which has been used for over a decade for modelling magnetocaloric devices at DTU. Modelling activities will include material screening, development of more detailed and more computationally efficient regenerator models and assessing design concepts for the prototype magnetocaloric system. The results of the modelling will be crucial for the project partners, who will realize a liquefaction prototype, and you will get to collaborate with these partners.

Responsibilities and qualifications
The main task of this three year postdoc is to model an active magnetic regenerator applied to a cryogenic hydrogen liquefaction system. This will involve developing new modelling strategies, taking into account innovative aspects such as novel magnetocaloric materials and new system applications. The postdoc will work closely with other partners to implement material properties into the model and incorporate the prototype design into the system model.

Qualified applicants must have:

  • PhD degree in engineering, physics or similar.
  • Experience with heat and mass transfer or numerical techniques.
  • Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamic group.
  • Good communication skills in English, both written and spoken.

Experience in the following is desirable:
  • Experience with MATLAB or similar programming languages
  • Experience with magnetocalorics or similar materials.
  • Experience with machine design.
  • Experience with cryogenics.

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.

The salary and appointment terms are consistent with the current rules for postdocs. The period of employment is 3 years. The expected starting date is the summer of 2023 but the start date is flexible.
