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.
The alkaline and chlorine industry, also known as the “chlor-alkali industry,” includes plants primarily engaged in producing chlorine, sodium hydroxide (i.e., caustic soda), and other electrolysis co-products. Other important products include potassium hydroxide (i.e., caustic potash) or hydrochloric acid and sodium hypochlorite (bleach).
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.
Chlorine is a highly effective disinfectant used extensively in water treatment. It is estimated that in 2020, the U.S. chlor-alkali industry consumed 94 TBtu (28 TWh) of electricity and 36 TBtu of fuels, mainly natural gas. If you do not manage energy, your business is giving money away to the utility.
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).
Implementing this measure saves up to 20% of the energy used in compressed air systems annually for space heating (Radgen and Blaustein 2001). Chlor-alkali plants use fan systems to support the boiler and for ventilation purposes. Considerable opportunities exist to upgrade the performance and improve the energy efficiency of fan systems.
