Biswajit Karmakar

It might be the hydrogen solubility lesser than CO2.

Duried Alwazeer

The solubility of CO2 in water at 20°C (1.6 g/kg) is 1000 times the solubility of hydrogen.

Muhammad Ali

Thanks this really helps.

Any idea about high pressure and high temperature conditions? Let's say at 50 C and 20 MPa?

Murad Abuaisha

Yes hydrogen solubility in water or brine is two orders of magnitude lesser than that of CO2. Usually gases dissolution reduces with the degree of salinity.
