PhD scholarship in "Investigating thermal energy storage via NH3 absorption/desorption processes"
The section for Electrochemical Materials and Interfaces (EMI) at DTU Energy, Technical University of Denmark (DTU),
invites application for a PhD scholarship in the area of Thermal Energy Storage.
The PhD Scholarship is supported by the Nordforsk organisation within the project "Neutrons for Heat Storage". Three
academic institutions, IFE (Norway) for the neutrons studies, KTH (Sweden) for the reactor designs and DTU (Denmark)
for the material characterization and synthesis, together with AMMINEX Emissions Technology (Denmark) as industrial
partner are parts of the project.
Responsibilities and tasks
To support the transition to fossil free society and economy, energy storage and particularly thermal energy storage has
been identified as a strategic technology. Within the "Neutrons for Heat Storage" project, we will study and build a cost
effective and compact thermochemical heat storage system based on ammonia salts (2-3 kWh storage capacity), thanks to the
heat which can be stored and recovered from the desorption and absorption of the ammonia into the salts.
The successful candidate will be involved in the three different phases of the project.
1.Synthesis and structural characterization of the chosen ammonia salts to be used in the thermochemical heat storage system.
Using combination of X-ray and Neutron diffraction, s/he will characterize structurally the different phases of the salts,
with no ammonia, fully ammoniated and the possible intermediates. S/he will characterize the macrostructure developing during
the swelling and shrinking of the salts.
2. Development of the storage tank - Neutron radiography will be performed on prototype reactor vessels during a 6-months stay at
IFE (Norway). The obtained information will guide to improve the design of the reactor prototypes for which the student will have
a three months stay at KTH (Sweden).
3.Building and testing of the Thermochemical Heat Storage system.
The candidate will participate in the ongoing effort to build up competences at IFE and in the Nordic region on the use of Neutron
Imaging applied to energy materials. S/He will work in close collaboration with the academic and industrial partners, promoting
long-term excellence and capacity building in research using neutrons including industrial applications.
Candidates should have a master’s degree in physics, chemistry or materials science or a similar degree with an academic level
equivalent to a master’s degree in engineering.
A successful candidate:
has good ability to work in a multi-disciplinary environment
is able to work independently and take responsibility for progress and quality of projects
has good writing and communication skills in English
We favour candidates with experience in instrumentation, in computational physics, chemistry and related areas.
Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the
general degree programmes of DTU. For information about the general requirements for enrolment and the general planning
of the scholarship studies, please see the DTU PhD Guide
The assessment of the applicants will be made by Didier Blanchard, Peter Holtappels and Guangling Zhao.
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation,
which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom
tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks
with the best universities in the world.
Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.
The work place will be at DTU Energy, Risø Campus, Roskilde
Further information may be obtained from Senior Researcher Didier Blanchard,
firstname.lastname@example.org and Prof. Peter Holtappels, email@example.com.
Please submit your online application no later than 15 February 2017. Apply online at
Applications must be submitted as one pdf file containing all materials to be given consideration. To apply, please open the
link "Apply online," fill in the online application form, and attach all your materials in English in one pdf file. The
file must include:
A letter motivating the application (cover letter)
Grade transcripts and BSc/MSc diploma
Excel sheet with translation of grades to the Danish grading system (see guidelines and
excel spreadsheet here)
Candidates may apply prior to obtaining their master’s degree, but cannot begin before having received it.
All interested candidates irrespective of age, gender, race, disability, religion or ethnic background are encouraged to apply.
The Department of Energy Conversion and Storage is focused on education, research, and development within functional materials
and their application in sustainable energy technologies. In a sustainable energy system, a large part of the energy will be supplied
by fluctuating sources such as solar and wind power. This makes it critically important to be able to convert and store the energy as
needed. At DTU Energy we work on fuel cells, electrolysis, solar cells, batteries, magnetic refrigeration and other sustainable energy technologies.
The Department, which has more than 200 employees, was founded in 2012. We are currently present on both Risø Campus, close to the town
of Roskilde, and Lyngby Campus, north of Copenhagen. In 2019, the entire department will be moving into new facilities at Lyngby Campus.
DTU is a technical university providing internationally leading research, education, innovation and scientific advice. Our staff of
5,800 advance science and technology to create innovative solutions that meet the demands of society; and our 10,600 students are
being educated to address the technological challenges of the future. DTU is an independent academic university collaborating globally
with business, industry, government, and public agencies.
