Desalination of seawater solves energy storage problem

Can rechargeable seawater batteries be desalinated simultaneously?

Due to the unique structure, containing both aqueous (seawater) electrolyte and organic electrolyte, it is easy to implement simultaneous water desalination and energy storage if the system of rechargeable seawater batteries is modified. In 2018, Zhang et al. proposed a rechargeable seawater battery desalination system.

How can seawater desalination technology reduce energy consumption?

Thereby, this technology could combine with some filtration technologies playing the role of pretreatment and the 2nd pass treatment to desalinate seawater; this technology could also replace some units or be added additionally in the current seawater desalination plants to reduce the energy consumption.

Is seawater desalination a viable strategy?

Desalination emerges as a viable strategy (Fig. 1), capitalizing on the copious and accessible nature of seawater. Seawater desalination methods, mainly including ultrafiltration, and electrodialysis (ED), reverse osmosis (RO), and other methods [15, 16]. Fig. 1. Visual maps of journals generated by VOSviewer.

Can seawater batteries desalination reduce energy consumption?

Considering the energy recovery of seawater batteries desalination technologies (i.e., discharging process), the energy consumption could reduce to around 5 kWh m −3 with the energy recovery reaching 90% by declining the voltage gap during the cycling. Table 3.

How much energy does seawater desalination use?

Reverse osmosis is dominant in desalination with an energy consumption of 3–5 kWh m −3, which consumes more than 70% of the energy of the whole seawater desalination plants. [41, 42] More energy-efficient technologies are required for large-scale seawater desalination.

Can seawater electrolysis be combined with desalination?

The integration of seawater electrolysis and desalination techniques presents a substantial opportunity to address the planet's expanding need for renewable energy and clean water resources [125, 126]. Water electrolysis generally necessitates the use of ultrapure water and can be efficiently conducted in PEMWE electrolyzer .
