GRAPHESALT: Water desalination based on grapheme electrodes

Graphesalt

GRAPHESALT is a new hybrid material for CDI electrodes. It is based on 3D-grapheme (oxide), which overcomes the three critical limitations of the current electrodes:

  • Has high capacitance (> 200 F/g)
  • Specific raised surface area
  • Elevated electroadsorption capacity due to its specific porous structure

Sectors

Chemical and petro-chemical industry and biorefinery
Construction equipment and facilities
Infrastructure

PROBLEM/OPPORTUNITY

In 2025, 2 billion people are expected to reside in water-scarce regions and 2/3 of the world's population will live under water-stressing conditions. ​

Current desalination technologies have a very high CAPEX and energy consumption: reverse osmosis (2.9-3.7 kWh/m3) and multi-stage flash distillation (4 kWh/m3).

The alternative is capacitive deionisation (CDI), with energy consumption of the order of 1 kWh/m3.

However, use is very limited by constraints in electrode materials.
