The partner organisation, Sigma Energy Storage, develops energy storage by gas compression. This technology is based on the storage of electricity from intermittent energy sources, such as wind or solar power. During the gas compression, carbon dioxide can be liquefied and extracted. This project aims to convert carbon dioxide into a valuable fuel, which could be reused to fuel the machines, and thus having a low carbon footprint on the environment.
The proposed internship aims to study how the performance and the reliability of mechanical energy storage systems influence their life-cycle cost (LCC), including the acquisition cost, the maintenance, and the energy costs. First, the effect of the variation of the design parameters on the performance and acquisition cost of the product will be assessed. Second, the effect of materials and processes on the reliability and the LCC of product will be studied. Lastly, the energy cost associated with the operation of the product will be analyzed.
