How much hydrogen can be produced by Enapter’s electrolyser and how long does it take to fill a 500 L tank?

Enapter’s electrolyser produce 0.5 Nm³/h (500 NL/h) or 0.04494 kg/h. One electrolyser module produces 12 Nm³ of hydrogen gas in 24 hours, weighting >1kg (1.0785kg). At the normal output pressure of the electrolyser with 35 barg, 1 kg of hydrogen

Enapter’s electrolyser produce 0.5 Nm³/h (500 NL/h) or 0.04494 kg/h. One electrolyser module produces 12 Nm³ of hydrogen gas in 24 hours, weighting >1kg (1.0785kg). At the normal output pressure of the electrolyser with 35 barg, 1 kg of hydrogen occupies a volume of 0.343m3 (343 L).

A full tank of hydrogen for a passenger vehicle contains about 5 kg of hydrogen gas (stored at 700 bar) and can drive for over 500 km.

Filling up a 500 L tank with one EL running at 100% and at 35 barg takes about 500 L * 35 / 500 NL/h = 35h until it is full.
