Highlights LAES is potential for frequency regulation, black start, clean fuel, load shifting. Decoupled LAES is flexible, portable, cold-electricity-supply, yet costly currently. Standalone LAES has a round-trip efficiency of 50–60 % and limited economic benefits. Hybrid LAES has compelling thermoeconomic benefits with extra cold/heat contribution.

Land reserve projects lay the foundation for land financialization by producing reserved land, which can become a tradable commodity or mortgage. Land reserve projects have four steps, including land acquisition, the primary development of land (or site preparation), land holding, and land disposition ( Huang and Chan, 2018 ).

The water storage efficiency evaluates the storage of water in the root zone after the irrigation in relation to the need of water prior to irrigation. Es= 100 (Vs/Vrz) (28.4) Where, Es= the storage efficiency (%) Vrz= the root zone storage capacity (m3). The root zone depth and the water-holding capacity of the root zone determine Vrz.

PCM can store energy more efficiently, releasing it when demand is high. This efficiency is vital for commercial settings such as multifamily housing, universities, and hospitals, where there is a constant and high demand for hot water. PCM’s ability to provide energy on demand means less strain on the heat pump and lower overall operating costs.

The best aspect of pumped hydro as an energy storage method is that it is relatively inexpensive and long-lasting. It has very high round-trip efficiency, which means little power is wasted while it generates electricity. Most are designed to store between 6-20 hours of energy, with the amount of energy dependent on the system’s size.

Solar battery storage efficiency refers to how effectively a battery system converts and stores solar energy. It is typically measured as the ratio of the energy stored in the battery to the amount of energy put into it. Higher efficiency means less energy loss during storage, which increases the usable energy available for later consumption.
