Approaches
As the required compression power for water is less than that for hydrogen-gas the water is pumped up to a high-pressure, in the other approach differential pressure is used. There is also an importance for the electrolyser stacks to be able to accept a fluctuating electrical input, such as that found with renewable energy. This then enables the ability to help with grid balancing and energy storage.

Famous quotes containing the word approaches:
“No one ever approaches perfection except by stealth, and unknown to themselves.”
—William Hazlitt (1778–1830)
“As the truest society approaches always nearer to solitude, so the most excellent speech finally falls into Silence. Silence is audible to all men, at all times, and in all places. She is when we hear inwardly, sound when we hear outwardly. Creation has not displaced her, but is her visible framework and foil. All sounds are her servants, and purveyors, proclaiming not only that their mistress is, but is a rare mistress, and earnestly to be sought after.”
—Henry David Thoreau (1817–1862)
“These were not men, they were battlefields. And over them, like the sky, arched their sense of harmony, their sense of beauty and rest against which their misery and their struggles were an offence, to which their misery and their struggles were the only approaches they could make, of which their misery and their struggles were an integral part.”
—Rebecca West (1892–1983)
