At the 2025 SMM Zero Carbon Path - PV and Energy Storage Summit hosted by SMM, Halim He, Director for the Middle East and Central Asia at CRRC Zhuzhou Locomotive Research Institute Co., Ltd., shared insights on the topic of "CRRC Battery Energy Storage System Solutions and New Features." He stated that the demand for battery energy storage systems in the Middle East is steadily increasing. However, local energy storage systems face numerous challenges, including difficulties in operation and maintenance, weak power grid infrastructure, and limited cross-border power transmission lines. To address these issues, CRRC has provided corresponding solutions.
Outlook and Challenges
Steady Growth in Demand for Battery Energy Storage Systems in the Middle East
Saudi Arabia: A Core Driver of Energy Storage in the Middle East
The Saudi Ministry of Energy plans to tender 24 GWh of battery energy storage projects from 2024 to 2025, with 18.6 GWh already initiated in 2024.
Saudi Arabia aims to achieve 50% renewable energy by 2030, developing at an annual rate of 20 GW to reach 130 GW by 2030.
UAE: Green Hydrogen Strategy and Utility-Scale Projects
Energy storage is critical for green hydrogen. Utility-scale energy storage demand is expected to rise in 2025.
Other Middle Eastern Countries: Emerging Markets
Egypt plans to build 35.56 GW of renewable energy, with a storage ratio of 15%-20% for a duration of 4 hours.
Oman plans to construct a 1.5 GW solar-storage project, which will be tendered in 2025.
Qatar is accelerating its energy transition and increasing energy storage demand following the World Cup.
Challenges for Energy Storage Systems in the Middle East
Power Grid Compatibility and Stability Requirements
Weak power grid infrastructure and limited cross-border power transmission lines. Energy storage systems need to have grid-forming capabilities to handle critical functions such as frequency regulation and black start.
Low Return on Investment in a Price-Sensitive Market
Abundant oil/natural gas → Low traditional energy prices → Low renewable energy on-grid tariffs → Low return on investment → Cost sensitivity among project owners.
Safety and Environmental Issues
Extreme temperatures up to 55°C and dusty environments; safety at large sites is a top priority.
Difficulties in Operation and Maintenance
Large-scale energy storage stations; long-term warranty extensions; battery recycling requirements.
