LCA of carbon capture technologies

Semester project or Master thesis, Spring semester 2025

Description

This project aims to perform a comprehensive life cycle assessment (LCA) to evaluate the environmental impact of implementing adsorbents in carbon capture systems. The study will compare different processes, such as Temperature Swing Adsorption (TSA), Temperature-Vacuum Swing Adsorption (TVSA), and Vacuum Pressure Swing Adsorption (VPSA), using MOFs, Silica, and Zeolites. The goal is to identify the most sustainable and environmentally friendly process for industrial-scale CO₂ capture.

Objectives

  1. Environmental Assessment:
    Conduct a cradle-to-grave analysis to quantify the environmental impacts of adsorbent materials and in carbon capture.

  2. Process Comparison:
    Compare the sustainability of TSA, TVSA, and VPSA technologies using environmental indicators such as greenhouse gas emissions, energy use, and resource depletion.

  3. Material Evaluation:
    Assess the environmental trade-offs of using different adsorbents like MOFs, Silica, and Zeolites in terms of production, usage, and disposal stages.

  4. Data Analysis:
    Use LCA tools and databases to generate quantitative insights for process and material optimization.

  5. Sustainability Reporting:
    Provide actionable recommendations for selecting adsorbent materials and processes that align with global sustainability goals.
