Energy Saving in Acid Lead Battery Factory with Container Formation Facility

PP(Japan): Hitachi Chemical Company, Ltd.  PP(Vietnam): CSB Battery (Vietnam) Co.,Ltd.

Outline of GHG Mitigation Activity

Currently, CSB Battery (Vietnam) manufactures small valve-regulated lead-acid (VRLA) batteries* (so-called sealed battery) with the tank formation method (See the chart below). This project introduces container formation method to some production lines, and about 60% of CO2 from fossil fuel combustion is reduced by integrating formation and charging processes, which consume much of energy in the 11-step battery production, and eliminating a drying process and LPG usage. Furthermore, this new formation method reduces water consumption by removing washing step.

(*Compared to flooded lead-acid battery, it doesn’t need to refill water and is utilized in various ways, such as in uninterruptible power supply (UPS).)

 

 

Expected GHG Emission Reductions

2,880 tCO2/ year

Emission reductions

= Reference emission reductions (RE)
  – Project emission reductions (PE)
= 4,761.0 tCO2/year – 1,880.8 tCO2/year
RE: CO2 emissions from battery production with tank formation method
PE: CO2 emissions from battery production with container formation method
