The Bridging Technology
• An electrolyzer is an electro-chemical
conversion device that utilizes an electric
current to separate water into hydrogen
and oxygen.
• An electrolyzer stack has no moving
parts, produces no harmful emissions
and operates at high efficiencies.
• Hydrogenics is the worldwide leader in
water electrolysis.

3. Myth #1: Making Hydrogen is Very Inefficient
e-
1 m3 contains
H2 and requires
1 m3 of Water 111 kg of Hydrogen 5 MWhr of energy to
convert with an electrolyzer
energy
H2 contains
111 kg of Hydrogen 4.3 MWhr of energy (HHV)

5. Highly Dynamic Technology
Hydrogenics’ HySTAT TM electrolyzer provided frequency regulation
in Ontario by responding to real-time frequency regulation signals
from the IESO on a second-by-second basis.

6. Myth #3: Hydrogen Can’t be Distributed in
Existing Pipelines
Hong Kong and China Gas Company has 3000km of
pipeline, serves 1.6 million customers with ~49% hydrogen
In Hawaii, The Gas Company has 1,770km of pipeline with
~11% hydrogen
In Europe, France, Germany, Austria and Switzerland have
set current limits of allowable hydrogen at 5% by volume
Small quantities of hydrogen are technically
manageable in gas pipelines.
