Systems and methods of water treatment for hydrogen production
A method includes providing raw water into a first filter assembly to remove solids from the raw water to form a filtrate, providing the filtrate from the first filter assembly into a second filter assembly to electrochemically remove ionics from the filtrate to form purified water, and providing the purified water to an electrolyzer to generate hydrogen by electrolyzing the purified water.
1. A method, comprising:
providing raw water into a first filter assembly to remove solids from the raw water to form a filtrate;
providing the filtrate from the first filter assembly into a second filter assembly to electrochemically or electrically remove ionics from the filtrate to form purified water;
providing the purified water to an electrolyzer to generate hydrogen by electrolyzing the purified water;
pressurizing the hydrogen generated by the electrolyzer in a hydrogen pump; and
recirculating the pressurized hydrogen to the electrolyzer.
2. The method of claim 1 , wherein the second filter assembly includes an electrodialysis cell, an electrooxidation cell, or a combination thereof.
3. The method of claim 1 , further comprising providing the hydrogen generated by the electrolyzer to an ammonia synthesis reactor to produce ammonia.
4. The method of claim 1 , further comprising storing the hydrogen generated by the electrolyzer in a hydrogen storage vessel.
5. The method of claim 1 , further comprising providing the hydrogen generated by the electrolyzer to a generator.
