• 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.

Highly Dynamic Technology

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.
