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:
“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)
“Someone approaches to say his life is ruined
and to fall down at your feet
and pound his head upon the sidewalk.”
—David Ignatow (b. 1914)
“Bloody men are like bloody buses—
You wait for about a year
And as soon as one approaches your stop
Two or three others appear.”
—Wendy Cope (b. 1945)
