How will you contribute?

After the International Energy Agency, cooling our food and houses requires today 20 % of all the energy needed in the residential sector. This share will grow to 40 % by 2040 as a direct consequence of the world population increase and the global warming effect. This industry accounts for 10% of all CO2 emissions, which is three times more than what is generated by aviation and shipping. The existing cooling technologies are overwhelmingly dominated by the vapour-compression systems, which is a 150 years-old technology relying on greenhouse gases and exhibiting an average efficiency less than 50 %. We clearly need to come up with more efficient cooling principles.

LIST has recently been very successful at showing that electrocaloric cooling is a convincing technology when it comes to efficient cooling alternative principles (Alvar Torello et al. Science 2020; Junning Li et al., Science, 2023). In this study, we want to investigate electrocaloric polymers of different compositions to study their behaviour in a cooling regenerator. This study will be performed in collaboration with ARKEMA in France. Arkema is the first provider of polyvinylidene difluoride in the world and is interested in finding alternative applications for this well-known polymer. The objective of this project is to make a cooling proof-of-concept based on electrocaloric polymers made of different compositions able to exhibit a temperature span reaching 20 K.

You will be to fabricate polymer-based electrocaloric regenerators based on polymers of different compositions. This requires a strong taste for experimental studies, a good knowledge of electrical measurements and a good command of Python coding. Most of the work will be related to assembling polymer-based devices, preparing fluid-based circuits compatible with voltage to make heat exchangers based on these polymers and testing these devices (voltage, current, temperature change, cooling power). Thermodynamic knowledge is also mandatory for this position. Modelling based on finite element will also be part of the job in this position.
