Master’s Thesis Project

– Investigation of Nanocoated Materials for Open & Closed Sorption Cycles

SaltX has invented a patented technology to store energy with salt. When SaltX is implemented it enables a significant higher energy efficiency to end customers. Today SaltX work with partners such as Vattenfall, Alfa Laval and Goldwind. Now we need Master student thesis project to support evaluation activities of nanocoated open and closed sorption cycle materials.

Background
SaltX Technology has designed and developed various thermally driven systems for solar cooling, heat pumping and energy storage purposes in closed-sorption cycles. Another developing sector which is of increasing importance is open-sorption cycles and desiccant dehumidification which allows for energy efficient and accurate control of humidity as well as thermochemical energy storage. A hygroscopic substance is employed to absorb moisture while renewable thermal energy or waste heat may be used to dry the substance thus preparing it for reuse (i.e. regeneration). SaltX Technology has been developing various desiccant materials with specialised nanocoating to enhance moisture absorption efficiency whilst maintaining absorption capacity over a large number of regeneration cycles. Desiccant dehumidification can be employed in applications such as; pharmaceutical production, shipping, air-conditioning systems and electrical device production amongst others.

A Master’s thesis project to support evaluation activities of nanocoated open and closed sorption cycle materials has thus been proposed.

Objectives

  • Carry out a literature study on material coating mechanisms and desiccant dehumidification materials
  • Experimentally investigate the coating efficiency of 2 to 3 nanocoating materials, alternatives and techniques.
  • Design and implement testing of the sorption capacity of materials under various conditions.
  • Measure, collate and evaluate the performance data of the sorption materials.

Project description

The project will be conducted partly at KTH, partly at SaltX facilities in Southern Stockholm.

The project comprises a literature study, experimental design, an experimental study, and thesis writing. The project should be reported both via the thesis report as well as with an oral presentation.
