To limit global mean temperature to 1.5°C relative to pre-industrial levels, global CO2 emissions must be decreased and become net zero at some point. As the energy sector is the main source of greenhouse gases, it also has the highest potential for improvement. [1] Improvements that can be reached by shifting to renewable energy sources. Concentrated solar plants coupled with thermal energy storage are a promising technology for dispatchable renewable energy. This technology can assure energy supply even in remote areas without contributing to greenhouse gases emissions during its operation. However, greenhouse gases, and other emissions, could be present during the fabrication process of components that make up the concentrated solar plant.
