The total investment of the Dengkou Electric Energy Storage New Energy Project in Inner Mongolia is 2.137 billion yuan. This phase plans to build an electrochemical energy storage power station with a capacity of 605MW/1410MWh, which is an important part of the future construction of a new power system. This project adopts an innovative flow energy storage system, which plays a significant role in addressing the consumption of new energy, enhancing the flexibility of the power system, and improving the safe and stable operation of the power grid. It is of great significance to the economic and social development of the region.
The preparation and liquid injection processes of positive and negative electrode materials for lithium batteries may come into contact with organic solvents (such as dimethyl carbonate), and the concentration of flammable gases needs to be monitored near the coating machine and liquid injection equipment.
If there are vehicles with faulty batteries near the charging piles, flammable gases may be released. Detectors should be deployed in the charging Spaces and distribution rooms to ensure the safety of personnel.
Explosion-proof detectors should be installed in areas such as hydrogen refueling machines and hydrogen storage cylinder groups to link with emergency shut-off valves to prevent hydrogen leakage from causing explosions.
Hydrogen leakage is prone to occur in electrolytic water hydrogen production workshops and high-pressure hydrogen storage tank areas. High-sensitivity alarms should be installed at pipe joints and valves, with the threshold set at 10% to 25% of the lower explosive limit (4%).
