Johnson Matthey Battery Systems' technologies have wide potential application in the growing energy storage sector.

Energy storage batteries

Grid energy storage refers to the methods used for large-scale electricity storage within an electrical power grid. Electrical energy is stored during times when production (from power plants) exceeds consumption and these stores are then used at times when consumption exceeds production. In this way, electricity production need not be drastically scaled up and down to meet momentary consumption; instead production is maintained at a more constant level. This has the advantage that fuel-based power plants (i.e. coal, oil, gas) can be more efficiently and easily operated at constant production levels.

Energy storage is also relevant to renewable energy sources. Renewables, such as photovoltaic cells and wind turbines, are by their nature intermittent energy sources and therefore require storage. Battery systems can play a role here in stabilizing power distribution networks.

Johnson Matthey Battery Systems is able to meet energy storage requirements through:

  • Understanding and experience of large capacity batteries
  • Flexible design and manufacturing capabilities
  • In-depth cell chemistry knowledge and partnerships with key cell suppliers
