Life-Cycle Feasibility of a Prefabricated Structural Panel for Carbon Storage in the Nordic Construction System

Summary:This presentation explores the development and life-cycle feasibility of an innovative hybrid structural panel designed to transition the built environment from a carbon source to a carbon storage system. The research addresses the fragmented landscape between material innovation, environmental assessment, and building performance by integrating these domains into a unified framework. Key Research Highlights: Hybrid Material Strategy: Combines Mineral Carbonation (CO₂ capture in a stable mineral matrix) with Biogenic Carbon Storage (engineered wood-based core) to achieve net-negative embodied carbon. Design Space Exploration: Instead of a single product, the research defines a multi-dimensional design space to evaluate trade-offs between carbon storage, structural performance, and durability in harsh Nordic climates. Transparent LCA Framework: Implements a robust "Cradle-to-Gate" Life-Cycle Assessment (LCA) methodology that separates biogenic and mineral carbon flows to ensure accurate, non-double-counted accounting. Technical Challenges Addressed: The research identifies and investigates critical technical hurdles for real-world application, including: Interfacial bonding and adhesion between mineral and wood layers. Moisture transport and freeze-thaw resilience in Nordic conditions. Carbon permanence and long-term stability of stored CO₂. Impact and Policy Context: This work aligns with EU Taxonomy Regulations and the EU Green Deal, providing scientific data to support the transition toward a resource-efficient, climate-neutral built environment by 2050.
