The Xintian Energy Storage Power Station Project of CGN New Energy is invested and constructed by CGN (Hunan) New Energy Development Co., LTD., with a total investment of 400 million yuan. After the project is put into operation, it will pay an annual tax of 4 million yuan. This will not only meet the development needs of new energy in the whole province, but also enhance the regulation capacity of the power system, relieve the transmission pressure of new energy in the Xintian area and the consumption level of new energy, improve the reliability of power supply in the power grid, and enable the power grid to operate safely and economically.
During the disassembly process of used batteries, flammable gases (such as electrolyte evaporation) may be released. It is necessary to install alarm devices in the disassembly assembly line and the waste gas treatment area to monitor the gas concentration.
Equipment such as photovoltaic inverters and energy storage battery compartments may release hydrogen due to faults (such as thermal runaway of lithium batteries). It is necessary to install alarm devices in battery rooms and equipment rooms to monitor the hydrogen concentration in real time and prevent the risk of explosion and combustion.
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%).
