Application

Design takeaway

When designing thermal energy storage systems, actively incorporate strategies for material reuse and recycling into the initial design phases, and critically assess material choices for their end-of-life potential.

How to apply

When evaluating or designing thermal energy storage solutions, use a composite indicator that assesses both environmental impacts (via LCA) and material circularity (via MCI) to guide design decisions towards more sustainable and circular outcomes.

Project actions

  • 01When researching materials for your design, consider not just performance but also their recyclability and potential for reuse.
  • 02Explore tools like Life Cycle Assessment (LCA) and Material Circularity Indicators (MCI) to quantify the environmental impact and circularity of your design choices.

Method & Evidence

AimHow can a framework integrating life cycle assessment and material circularity indicators be used to evaluate and enhance the sustainability of thermal energy storage systems within a circular economy context?
MethodFramework Development and Case Study Application
ProcedureA methodology framework for Sustainable Circular System Design (SCSD) was developed, incorporating an Environmental Sustainability and Circularity (ESC) indicator. This indicator combines Life Cycle Assessment (LCA) for environmental impacts and the Material Circularity Indicator (MCI) for circular performance. The framework was applied to a high-temperature thermal energy storage system using molten salts in a concentrated solar power plant, analyzing scenarios with increased recycling and reuse rates.
ContextRenewable energy systems, specifically thermal energy storage in concentrated solar power plants.

Strengths & Limitations

Strengths

  • +Provides a novel composite indicator (ESC) for evaluating sustainability and circularity.
  • +Applies a structured methodology to a relevant real-world case study.

Limitations

The availability of data for LCA and MCI can be challenging for novel materials or complex systems. Real-world implementation of reuse and recycling processes may differ from theoretical models.

Reliability & validity

The validity of the ESC indicator relies on the accuracy of the LCA and MCI calculations. Reliability would be enhanced by using standardized LCA databases and consistent MCI calculation methods across different case studies.

Think critically

To what extent can the principles of this framework be applied to product categories beyond energy storage, and what are the primary challenges in adapting such a comprehensive sustainability assessment?
