dc.description.abstract | The circular economy can be promoted as a solution to support the sustainability market position of
renewable energy systems. To design a circular and sustainable system, a structured approach is needed.
The present study develops a methodology framework for sustainable circular system design (SCSD),
aiming to assess thermal energy storage (TES) technologies from a sustainable perspective. To this end, a
composite indicator, namely, environmental sustainability and circularity indicator (ESC) is provided.
This indicator combines the environmental impacts of the TES system via the conduction of a life cycle
assessment and its circulatory performance using the product-level material circularity indicator (MCI).
The developed methodology is applied to a case study of high-temperature TES using molten salts as a
part of a concentrated solar power plant. The SCSD embraces the analysis for the most relevant processes
through proposing different ecological scenarios including, increasing the recycling rates (Modest Scenario), increasing the reuse rates (Medium Scenario), and a combination of both (Optimistic scenario).
The circularity analysis showed that for the Modest, Medium and optimistic scenarios, the MCI moves
from 20.6% for the current situation to 30.3%, 38.6%, and 46.4%, respectively. Accordingly, the optimistic
scenario showed the most environmentally sustainable and circular scenario with ESC of 7.89%, whereas
the Modest and Medium scenarios exhibited ESCs of 1.20% and 2.16%, respectively. A major obstacle for
substantial improvement of the circulatory and ESC is the high share of unrecyclable molten salts in the
system and therefore, any effort to improve the circulatory and the environmental benefits of this system
can be reached by using more environmentally friendly alternative materials. The study concludes that
the integration of reusing and recycling at the initial design should be sought in order to achieve a more
environmentally sustainable and circular outcome. | es |
