Challenges in Implementing LAES Systems
1. Low Round-Trip Efficiency
- Issue: LAES systems have a relatively low round-trip efficiency, typically ranging from 50% to 70%, which is lower than that of other energy storage technologies like lithium-ion batteries.
- Impact: This lower efficiency results in higher energy losses during the charging and discharging process, affecting overall system performance.
2. Capital Costs
- Issue: The initial investment for LAES facilities is substantial, with costs around £500 per kilowatt-hour in early 2025.
- Impact: High upfront costs can deter investment despite expected declines with technological advancements and scaling.
3. Geographic and Operational Limitations
- Issue: While LAES offers geographic independence, integrating external thermal systems to enhance efficiency often requires nearby thermal power plants or industrial facilities.
- Impact: This integration can undermine the inherent advantage of LAES systems, which is their ability to operate independently.
4. Environmental and Sustainability Concerns
- Issue: The use of external fuels to improve efficiency introduces CO2 emissions, which can lead to environmental issues.
- Impact: Addressing these emissions is crucial for maintaining sustainability in energy storage solutions.
5. Techno-Economic Challenges
- Issue: LAES systems are still premature in terms of full-scale operational data and techno-economic analysis.
- Impact: This lack of data hampers accurate predictions of system performance and affects commercialization efforts.
