Do you want to contribute to a sustainable future and to researching the energy technologies of tomorrow? At DTU Energy our research is targeting exactly this, and we are looking for new team members.
 

It is clear to all that the sooner we can stop relying on fossil fuels the better. Cars and small vehicles can be run on batteries and fuel cells. Larger vessels like aircrafts and ships for long distance transport needs higher energy density carriers, and liquid fuels or highly compressed gaseous fuels appear to be the only option. Various fuels can be synthesized by electrolysis and down-stream catalytic upgrading processes, but the question; which are the best and most sustainable alternatives remains unanswered.

 

Hydrocarbon fuels like methanol or methane may be synthesized from biomass, but research indicate that fuels obtained from bio-waste (straw, wood chips etc.) will not be sufficient to cover society’s needs, at least not without supplying additional hydrogen. This hydrogen can be obtained by splitting of steam via electrolysis. Due to scarcity of biomass resources, our research also considers fuels alternative to hydrocarbons for instance ammonia.

 

The solid oxide cell technology has the potential to become a key technology in the future sustainable energy system - acting both as fuel cells to generate power locally (SOFC) and as electrolysis cells (SOEC) to supply hydrogen (and maybe also nitrogen) to be used for synthesizing fuels for the transport sector. In the planned activities this technology will be benchmarked against alternatives such as alkaline electrolysis and proton-exchange membrane (PEM) fuel cells. 

 

We are working on a number of research projects, running in parallel, trying to answer the following questions:

  • What are the best sustainable fuels for transport, more specifically cargo shipping?
  • Do we have sufficient bio-waste to produce the needed fuels of tomorrow?
  • Which are the most attractive solutions when considering both the need for large scale energy storage (power2X) and value to the transport sector?

These questions we address by modelling at the system level describing overall efficiency and process economy of plants and synthesis routes for different sustainable fuels. We are looking to recruit two postdocs to help us researching this, i.e. constructing system models at the plant level involving initially the electrolysis units and peripheral components and describing overall process economy. Later system modeling of other energy technologies, such as novel thermal storage devices or novel batteries will also be part of the overall models. You will be working in a team on these topics, with local experts on the actual technologies.

 

This requires a background in physics, chemistry or mechanical engineering. Knowledge on energy conversion processes, energy system descriptions and techno-economical assessments are further advantageous.

 

The main activity will take place at the Department of Energy Conversion and Storage at DTU Lyngby campus.


Qualifications

Qualified applicants must ideally have:
  • PhD degree in engineering, physics, chemistry or similar.
  • Experience with system modelling software such as Aspen+ or similar
  • Knowledge of energy system, conversion and storage technologies
  • 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.
