Why purify?

14 oktober 2020

Although hydrogen is the most abundant molecule in the universe it hardly occurs in a free form on earth, but rather in a bonded form such as in methane and water. When hydrogen is produced from natural resources such as water or hydrocarbons, it is not in a pure form.

Trace amounts of contaminants such as nitrogen, methane, carbon monoxide, carbon dioxide etc, remain in the produced hydrogen. These contaminants need to be removed before using it for conversion processes in industry or in fuel cells. HyET’s Electrochemical Hydrogen Compressor (EHC) is capable of hydrogen compression and purification in one device. Because of the selectivity of the electrochemical cells in the EHC system it enables the purification of hydrogen from contaminants such as nitrogen or methane. In the latter case increasing the value of both gasses.

HyET Hydrogen’s Electrochemical Hydrogen Compressor therefore fulfils an essential role in the value chain of hydrogen supply, storage, and conversion.

It is therefore not surprising that the EHC technology is becoming increasingly popular as a reliable, modular and highly efficient system that combines hydrogen compression and purification in one processing unit without the use of moving parts.
