Drinking ultrapure water using the atomic composition of water, H2O, we can properly determine the amount of ultrapure water needed for the creation of green hydrogen.

Because oxygen is 16 times heavier than hydrogen, it accounts for 89% of the mass of water, which indicates that 9 liters of water are required to make 1 kg of hydrogen.

This ratio can be useful for determining the water requirements for a certain hydrogen production capability. For example, producing 100,000 tons of green hydrogen per year requires 900,000 m3 (tons) of ultrapure water.

Ultrapure water is the key input for the production of green hydrogen. Furthermore, cooling water may be required in the process and system. Overall, the water requirements for green hydrogen are stoichiometrically calculated at 9 L (2.37 gal) of water per kg (2.2 lb.) of green hydrogen produced.

Water Treatment Methods for Green Hydrogen Generation

Several methods can be employed to treat water for green hydrogen generation, each with its own advantages and limitations. The choice of water treatment method depends on factors such as water source, impurity levels, and project requirements. Some common methods include:

Reverse Osmosis (RO)

Reverse osmosis is a widely used water treatment method that utilizes a semipermeable membrane to remove impurities. It is effective in removing dissolved salts, minerals, and organic matter from water, resulting in high-quality water for electrolysis.

RO systems can be integrated into green hydrogen projects to ensure the production of clean and pure hydrogen.

Electro deionization (EDI)

Electro deionization is a water treatment process that combines ion-exchange resins and electricity to remove ions and impurities from water. It is a continuous and chemical-free method that produces ultrapure water suitable for green hydrogen generation.

EDI systems offer a sustainable and cost-effective solution for water treatment in green hydrogen projects.

UV Disinfection

UV disinfection is a non-chemical method that utilizes ultraviolet light to destroy bacteria, viruses, and other microorganisms present in water. It is often used as a final step in water treatment to ensure the removal of any remaining contaminants.

UV disinfection can be integrated into water treatment systems for green hydrogen generation to ensure the production of clean and safe hydrogen.

Several successful green hydrogen projects around the world have demonstrated the importance of effective water treatment in achieving clean and sustainable hydrogen production.

One such example is “Project H2O” in Germany, where a combination of reverse osmosis and UV disinfection was employed to treat water for electrolysis.

The project achieved high hydrogen yields and maintained the purity of the generated hydrogen, contributing to the overall success of the green hydrogen plant.

Another notable case is the “Hydrogen Oasis” project in Australia, where electro-deionization was utilized as the primary water treatment method.

The project was able to produce large quantities of high-purity hydrogen using renewable energy sources, showcasing the effectiveness of electro-deionization in green hydrogen generation.

These case studies highlight the significance of water treatment in green hydrogen projects and emphasize the need for tailored water treatment solutions to ensure optimal performance and sustainability.
