This thesis project explores the transformation of an active mining site into an infrastructure with a dual purpose. The project aims to address the negative environmental impacts associated with the mining industry and contribute to the development of a sustainable energy grid. Focusing on Boliden's Garpenberg Mine in Sweden, the proposal utilizes a technique called Mine Storage, which harnesses pumped storage principles to store and release energy. By repurposing mine shafts as energy storage systems, this approach enables the stabilization of the residual load curve and alleviates energy grid bottlenecks.

The project recognizes the challenges of mine reclamation, particularly concerning water pollution, and explores the potential for an architect's contribution in enhancing the outcomes of such projects. The proposed solution involves the creation of a wetland-like environment within the reclamation area, which acts as a natural filter, purifying water as it flows through. The wetland helps trap and break down pollutants, improving water quality and reducing the impact of pollution on downstream ecosystems.

The architectural design integrates the wetland with the Mine Storage infrastructure, aiming to provide a variety of conditions and habitats for biodiversity to thrive. The shape-shifting nature of the wetland, influenced by the operation of the energy storage system, creates visual effects and an intuitive understanding of the interconnectedness between electricity demands, local communities, and the environment. The proposal demonstrates the potential for an infrastructure to serve a functional purpose while also carrying symbolic meaning, engaging the community and raising awareness of sustainable practices.

Through research, collaboration with experts, and critical analysis of default solutions, the project emphasizes the importance of research as an integral part of the design process. It highlights the transformative power of architecture in creating dynamic and living structures that remind us of our responsibility to care for the environment. The proposed project presents a unique opportunity to repurpose a mining site, extending its lifespan, and contributing to a sustainable energy supply while fostering biodiversity and reconnecting communities with their natural surroundings.
