This paper presents a comprehensive review of the most popular energy storage systems including electrical energy storage systems, electrochemical energy storage systems, mechanical energy storage systems, thermal energy storage systems, and chemical energy storage systems.
Energy storage technologies have the potential to reduce energy waste, ensure reliable energy access, and build a more balanced energy system. Over the last few decades, advancements in efficiency, cost, and capacity have made electrical and mechanical energy storage devices more affordable and accessible.
Energy storage technologies can be broadly categorized into five main types: mechanical energy storage, electrical energy storage, electrochemical energy storage, thermal energy storage, and chemical energy storage [,,, ]. Mechanical energy storage has a relatively early development and mature technology.
For energy storage technologies to be used more widely by commercial and residential consumers, research should focus on making them more scalable and affordable. Energy storage is a crucial component of the global energy system, necessary for maintaining energy security and enabling a steadfast supply of energy.

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2022). 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.
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
Developer premiums and development expenses - depending on the project's attractiveness, these can range from £50k/MW to £100k/MW. Financing and transaction costs - at current interest rates, these can be around 20% of total project costs. 68% of battery project costs range between £400k/MW and £700k/MW.
Battery technology: The type of battery technology used in the storage system plays a significant role in the cost. Popular battery types include lithium-ion and LiFePO4, with varying costs and performance characteristics. System size and capacity: The larger the storage system, the higher the cost.
The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
Total System Cost ($/kW) = Battery Pack Cost ($/kWh) × Storage Duration (hr) + BOS Cost ($/kW) For more information on the power versus energy cost breakdown, see (Cole et al., 2021). For items included in CAPEX, see the table below. Components of CAPEX Inclusions in CAPEX
The Norwegian power system is almost entirely based on hydropower plants with storage reservoirs, with very small percent of variable energy sources, resulting in a robust power system with sufficient energy storage and frequency reserves.
Domestic gross energy consumption was 134,7 TWh in 2019, a decrease from the all-time high of 136,9 TWh in 2018. The Norwegian peak demand normally occurs in the winter season. The peak electricity demand was 23672 MWh/h in 2019, which is lower than the peak demand in 2018. Table 5. Peak demand for the last 10 seasons. Source: Statnett.
The Norwegian Quality of Supply Regulation includes minimum requirements for voltage frequency, supply voltage variations, voltage dips, voltage swells, rapid voltage changes, short- and long term flicker since 2014, voltage unbalance and harmonic voltages including total harmonic distortion (THD).
The total installed generation capacity in Norway was 36 493 MW as of 31.12.2019. Available generation capacity during a cold winter is estimated to approximately 26 500 MW by Statnett. The wind power generation capacity increased by 780 MW from 2018 to 2019, whereas the hydro power generation capacity increased by 277 MW.
Prohibitions of market manipulation and insider trading, requirements on disclosure of inside information and market surveillance was implemented in the Norwegian energy legislation and entered into force 1.3.2018. These provisions are similar to REMIT6, and Norway has harmonised market conduct rules with our neighbouring energy markets.
The Norwegian electricity network is characterised as transmission (400kV-132 kV) and distribution (132kV – 240V) network. Distribution network is further differentiated as regional distribution (132kV – 22kV) and local distribution (22kV – 240V) for regulatory purposes.
There are no regulated prices in Norway. Customers who have not yet chosen a supplier shall, the first six weeks, be served by their local DSO (supplier of last resort) at a price that is maximum øre/kWh 5 excl. VAT (or øre/kWh 6.25 incl. VAT) above spot price.

[PDF Version]Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
Figure 1 depicts 28 distinct business models for energy storage technologies that we identify based on the combination of the three parameters described above. Each business model, represented by a box in Fig- ure 1, applies storage to solve a particular problem and to generate a distinct revenue stream for a specific market role.
We propose to characterize a “business model” for storage by three parameters: the application of a storage facility, the market role of a potential investor, and the revenue stream obtained from its operation (Massa et al., 2017).
Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).
However, the current energy storage development still has the problem of insufficient business models and single energy storage income. With the continuous improvement of China's electricity market mechanism, a flexible market environment will provide more feasible business models and market space for energy storage development.
The main finding is that examined business models for energy storage given in the set of technologies are largely found to be unprofitable or ambiguous.
