Combining different energy sources and uses by Joe Cargnelli
Power-to-Gas: We’re ReadyJoseph CargnelliChief Technology OfficerHydrogenics CorporationJune 8th, 2012 | Toronto, CanadaFuture of Energy Summit
(+) DC Power (-) 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. 2
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) 3
Myth #2: Not Much Technology Progress 70 cm = 50 cm1MW Advanced 140 cm Electrolysis 49 cm 1MW of Commercial Electrolysis 4
Highly Dynamic Technology Hydrogenics’ HySTAT TM electrolyzer provided frequency regulationin Ontario by responding to real-time frequency regulation signalsfrom the IESO on a second-by-second basis. 5
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. 6
