Studies have shown that Trombe walls (TWs) with PCMs, due to their large latent heat capacity and narrow melting temperature range, can reduce energy consumption by 10% to 30% annually [28, 29]. The trombe wall is a passive solar system that allows you to harness solar energy for the internal climate control of buildings. However, due to their reliance on direct solar radiation patterns and limited thermal inertia characteristics, traditional TW systems exhibit inherent efficiency limitations. By. This property of solar radiation, described by Wien's displacement law, traps heat between the glass panel and masonry wall, allowing the Trombe wall to effectively absorb heat while limiting its re-emission into the environment. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it.

Statistics show the cost of lithium-ion battery energy storage systems (li-ion BESS) reduced by around 80% over the recent decade. As of early 2024, the levelized cost of storage (LCOS) of li-ion BESS declined to RMB 0.3-0.4/kWh, even close to RMB 0.2/kWh for some li-ion BESS projects.
Li-ion batteries have a typical deep cycle life of about 3000 times, which translates into an LCC of more than $0.20 kWh −1, much higher than the renewable electricity cost (Fig. 4 a). The DOE target for energy storage is less than $0.05 kWh −1, 3–5 times lower than today's state-of-the-art technology.
Lithium-ion (Li-ion) batteries are considered the prime candidate for both EVs and energy storage technologies, but the limitations in term of cost, performance and the constrained lithium supply have also attracted wide attention, .
For energy storage, the capital cost should also include battery management systems, inverters and installation. The net capital cost of Li-ion batteries is still higher than $400 kWh −1 storage. The real cost of energy storage is the LCC, which is the amount of electricity stored and dispatched divided by the total capital and operation cost .
Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
