6 FAQs about [Chlor-alkali light energy storage principle]

Can a chlorine flow battery be used for stationary energy storage?

The chlorine flow battery can meet the stringent price and reliability target for stationary energy storage with the inherently low-cost active materials (~$5/kWh) and the highly reversible Cl 2 /Cl − redox reaction. Integrating renewable energy, such as solar and wind power, is essential to reducing carbon emissions for sustainable development.

What are the energy inputs at a chlor-alkali plant?

At a glance, energy inputs at a chlor-alkali plant include the following. The most energy-intensive process in chlor-alkali manufacturing is electrolysis. It accounts for approximately 90% of the plant’s electricity consumption. The next most energy-intensive process is caustic soda concentration, especially when plants operate diaphragm cells.

How can a chlor-alkali cell reduce energy consumption?

Improved control of the brine/liquor flux can help reduce chlorate formation and energy consumption (Lima et al. 2010). At the commissioning of new chlor-alkali cells, the structural and contact voltage drops should be recorded and benchmarked (NPC 2017).

Does chlor-alkali membrane technology reduce cell voltage?

Existing chlor-alkali membrane technology has been optimized to the extent that no further reduction of the cell voltage is expected from additional cell or membrane modifications. Oxygen-supplied cathodes must satisfy two conflicting criteria, high gas permeability and low liquid permeability.

What are the disadvantages of chlor-alkali energy storage?

Damages in the membranes by the strong oxidizing capacity of chlorine were also highlighted in other works [50, 52, 53] and may become one of the main handicaps in this technology, especially when reversibility and integration is looked for. Figure 1. Scheme of the prototypes evaluated for application of the chlor-alkali energy storage. Table 1.

Is the US industry interested in a new energy-efficient chlor-alkali process?

Currently, there is low interest on the part of the U.S. industry in the new energy- efficient chlor-alkali process due to the high capital investment associated with the implementation of a new technology and the potential of hydrogen evolution from current cell technology having a future commercial value.
