Hydrogen Generation System

The world’s first non-catalytic water electrolysis with a method developed by H3-KOREA

Using the NICE (None Interval, Catalyst, Electrolyte / No Catalyst, No Electrolyte, No Separation Membrane) method, securing higher economic efficiency than the existing water electrolysis method.

  • Currently, water electrolysis electrodes use metals or alloys that are highly reactive to metals as catalysts, but there are concerns about performance degradation due to high voltage or corrosion of electrodes by the environment.
  • In order to overcome this, based on several tests by our R&D, we concluded that carbon materials can bring durability advantages compared to metal plates.
  • Through this R&D, we found and developed that a CNT-based carbon composite with excellent electrical conductivity is used for the anode material, and iron oxide is removed through modification of the STS material for the cathode material to secure durability, thereby minimizing the oxidation reaction and securing durability, so it can be used semi-permanently.
  • The market for hydrogen storage is formed by a gas compression method or liquefaction method. There is a risk of explosion due to the high pressure of up to 700 bar for hydrogen storage, charging, and transportation. So a solid storage alloy controlled under of 10 bar will be the safest method.

  • MH storage can store 5 times more than hydrogen gas and 1.2 times more than liquid hydrogen when comparing hydrogen storage per unit volume.

  • Metal Hydride will be a game changer for the future hydrogen ecosystem.

  • The most important part of MH storage is w.t%, which is a measure of how much hydrogen can be stored. Currently, commercialization is 1.76 w.t%, but our developed technology can exceed 3 w.t%.

  • In addition, it can be stored and transported in a container, so it can be transported to island areas, and there is no boil-off gas phenomenon of gaseous hydrogen or liquefied hydrogen.
