“…In comparison, a DLSC house produced only 1.91 tonnes of CO2 emissions per year, showing a reduction of 4.5 tonnes of GHG emissions per house per year. Considering the fact that TES systems contribute to 20% of the environmental footprint of a CSP plant, using a basalt-air packed bed storage system caused a reduction of about 12% for the GWP indicator, in the study by [37]. Further, in comparison to a conventional two tanks molten salt TES system, there was a 60% reduction in the GWP.…”

Renewable energy sources coupled with thermal energy storage (TES) systems offer a better hope in mitigating climate change. But, in order to integrate TES systems into the grid, it is important to understand their environmental performances. Life cycle assessment (LCA) serves as a leading methodological tool for environmental decision-making processes that allows one to identify the critical areas of improvement in a product life cycle, and hence can be used effectively in climate change mitigation strategies. Due to the scarcity of review articles that provide useful information on the LCAs of TES systems, a total of 23 papers were reviewed in this study. These were reviewed under three categories: sensible heat storage (SHS) systems, latent heat storage (LHS) systems, and thermochemical heat storage (THS) systems. Further, the greenhouse gas (GHG) emissions arising from TES systems were evaluated, giving special attention on the global warming potential impact category. The production stage was found to be the major contributor to GWP in all three TES systems. Following this review study, it can be concluded that the environmental performance can be greatly enhanced through TES systems, due to significant reductions in GHG emissions.

“…20 This part has been neglected in the current study. Furthermore, the choice of TES materials strongly influences the GWP value 39 : a Thermocline/Mullite system leads to 17 kg CO 2.eq / MWh versus 2 kg CO 2.eq /MWh for a Thermocline/basalt system. In the current case, the use of CaO/Ca(OH) 2 as the storage material reduces the impacts on GWP compared to other storage materials such as liquid salts or ceramics.…”

This paper presents an original life cycle assessment (LCA) of a concentrating solar power (CSP) plant with thermochemical energy storage (TCES). The studied CSP plant is a hypothetic solar tower plant with a Rankine power cycle, and the TCES material used is calcium hydroxide. Based on three proposed TCES integration concepts, detailed sizing and the associated emission inventory are performed for four main groups that constitute the CSP plant, including the solar field, the solar tower, the storage system and the power cycle. Various midpoint impact categories are evaluated using the IMPACT 2002+ method embedded in the SimaPro 7.3 software. A sensitivity analysis is performed to identify the most influencing elements of the CSP plant on the environmental impacts. LCA results show that the CSP plant with different TCES integration alternatives has comparable global warming potential (approximately 11 kg CO 2.eq /MWh) and energy payback time (approximately 4 months). The additional environmental burden due to the addition of the TCES system is relatively small (about 30%). The use of calcium hydroxide for the TCES has noticeable midpoint impacts on the respiratory inorganics, the terrestrial ecotoxicity and the mineral extraction. Solar field group (heliostat mirrors) is generally the most sensitive and environmental impacting factor of the CSP installation. The Turbine integration concept has the smallest environmental impacts among the three concepts proposed.

“…The LCA framework and data inventory on CSP systems were firstly detailed by Heath et al (2009) and Oró et al (2012) brought a global approach on TES systems LCA comparison. Further work detailed studies on heat storage systems containing waste (Lalau et al, 2016) or natural (Nahhas et al, 2020) TES material. Concerning the industrial waste heat domain, the previous work is scarce and mainly focused on latent heat storage, such as López-Sabirón et al who found that up to half the life cycle of a heat exchanger filled with phase change materials (PCM) was needed to payback its life cycle impacts by avoiding fossil fuel consumption (López-Sabirón et al, 2014a) or that some PCM may not be able to balance the TES system carbon footprint (López-Sabirón et al, 2014b).…”
