1. Preface. Global warming and severe air pollution caused by automobile exhaust pose a great threat to human health.

The growing concerns about climate change led to the ratification of the Paris agreement, which aims to limit the global warming below 2 ° C to pre-industrial levels .Following its ratification, the European Union (EU) has established a Climate Target Pact to cut GHG emissions by at least 55% by 2030, with the aim of becoming carbon-neutral by 2050 .
The energy density of various storage methods (N''Tsoukpoe et al. 2009), the volume reduction in the storage containment using various TES technologies (Pinel et al. 2011), classification of the chemical storage (Pinel et al. 2011) and the combination of working materials of thermochemical energy storage (Gores et al. 2012) are depicted in Fig. 1 a–d.
The following conclusions are drawn: 1) customer-sited energy storage could partially replace coal power plants to provide flexibility for integrating a high share of renewable energy into the power system; 2) CO 2 emissions can be significantly reduced at a cost of $30 per tonne; 3) customer-sited energy storage systems cannot gain profits based on the current
