There are significant differences in cost between different brands of energy storage systems. Here are some key points highlighting these variations:
Differences in Costs
- Residential Battery Systems: Prices for residential battery storage systems vary widely based on factors like capacity, brand, and installation costs. For example, a Tesla Powerwall 2 costs from around £5,800, while a Huawei Luna system can range from £3,000 to £6,000. The Alpha ESS Smile 5 is available from around £3,400, showcasing the cost variability.
- Lithium-Ion vs. Other Technologies: For utility-scale applications, lithium-ion batteries have seen rapid cost reductions due to economies of scale, but other technologies like thermal and compressed air storage can be cheaper for long-duration applications. Lithium-ion batteries, however, remain highly cost-competitive, especially in China.
- Regional Variations: Costs also vary significantly based on the region. In China, lithium-ion batteries and other long-duration energy storage (LDES) technologies are often cheaper than in other countries. This disparity is due to China’s advanced commercialization and large-scale projects driven by favorable policies.
- Economies of Scale and Technological Advancement: The cost of lithium-ion batteries has decreased dramatically due to widespread adoption and technological improvements. Other technologies, while potentially cheaper in certain applications, do not yet benefit from the same level of economies of scale.
Comparison of Costs
- Residential Systems: Prices range from approximately £2,500 to over £15,000 depending on capacity and brand.
- Utility-Scale Systems:
- Lithium-Ion: Typically around $304/kWh for 4-hour systems, with projections suggesting costs could fall to $159/kWh by 2050.
- Thermal Energy Storage: $232/kWh, offering one of the lowest costs for long-duration applications.
- Compressed Air Storage: $293/kWh, also more competitive for longer discharge durations.
In summary, while lithium-ion batteries remain a leading choice due to their cost-effectiveness and widespread adoption, other energy storage technologies offer competitive pricing in specific applications or regions.
