Combined Oxygen Generation System (COGS)

COGS incorporates an electrolyser and gas management plant in one compact unit. The high pressure electrolyser produces pure oxygen and the gas management module produces a liquid waste.

Technical specifications

Oxygen output

Typically in the range of 1 – 10 Nm3/hour

Oxygen output pressure

zero - 1 bar

Oxygen purity

99.5%

Plant pressure

zero - 60 bar

Cell stack current

100 – 600 A

Power

10 - 150kW

Equipment volume

Typically 3.5m3

Gas management system

To suit the system above

Electrolyser

TPG electrolysers take demineralised water and splits it into oxygen and hydrogen. Typically hydrogen is used as a temporary energy storage vector. This can be converted back to electricity by a fuel cell when required. 

Hydrogen output

Typically in the range of 2 – 20 Nm3/hr

Hydrogen pressure

0-60 bar

Hydrogen purity

99.998% or better

Power

10 - 150kW

Equipment volume

Typically 3.5m3
