Implementing liquid air energy storage (LAES) on a large scale faces several significant challenges:
Main Challenges
- Low Round-Trip Efficiency:
- LAES systems have a relatively low round-trip efficiency, estimated to be around 50–60% for large-scale systems.
- This low efficiency means that a substantial amount of energy is lost during the storage and retrieval process, impacting overall system performance and economic viability.
- Economic Viability and Financial Incentives:
- LAES systems require significant financial incentives to become economically viable. Research shows that providing subsidies on capital expenditures can significantly improve their viability, making them more attractive for investment.
- Without financial support, the economic feasibility of LAES may not compete favorably with other energy storage technologies.
- Technical Limitations and Integration Challenges:
- While LAES systems can operate independently without geographical constraints, integrating them with external thermal systems to improve efficiency can limit their flexibility. Such integration often requires nearby thermal power plants or facilities.
- Use of external fuels can enhance efficiency but may introduce CO2 emissions, complicating the sustainability of the system.
- Techno-Economic Analysis and Lack of Operational Experience:
- LAES technology is still in its early stages, with limited data from large-scale operating conditions. This makes techno-economic predictions challenging and affects the commercialization of the technology.
- Off-design conditions are not fully understood, which is crucial for evaluating system performance.
- Policy and Implementation Barriers:
- While policies can quickly address economic viability, implementing these policies takes time. Additionally, there is a need for broader support and regulatory frameworks to foster the adoption of LAES technology.
