Abstract: This invention pertains to a new type of method and apparatus for separating, accumulating, compressing and subsequently storing hydrogen gas in a gas column separator system, whereby the lighter and lower density gas hydrogen may be pumped from the top of the column and the change in gas difference, when the higher density and heavier gas appears is sensed thus, automatically stopping the hydrogen gas compressor pump motor unit until the hydrogen gas in the top gas cells is replenished and sensing units probing such hydrogen content subsequently instruct aforementioned hydrogen compressor pump motor unit to resume pumping, such functions being in interaction with the operation of a hydrolizer unit, water supply pump, storage unit, and power supply means.
