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.

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.

Paragraph starter
The research by Abokersh et al. (2021) highlights the critical role of integrating circular economy principles into the design of energy storage systems. By developing a framework that combines Life Cycle Assessment (LCA) with Material Circularity Indicators (MCI), they demonstrated that enhancing reuse and recycling strategies can significantly improve the environmental sustainability and circularity of thermal energy storage technologies. This approach underscores the importance of considering a product's entire lifecycle, from material sourcing to end-of-life management, in achieving truly sustainable design solutions.
