Harnois Énergies, based in Quebec City, produces the hydrogen using an electrolyzer, which splits water into hydrogen and oxygen using electricity. Because the electricity is from Hydro-Quebec — which is 94 per cent hydro-generated, five per cent by wind and almost fully decarbonized — the resulting hydrogen is considered green. Such nearly ideal arrangements are far from universal, nor does it mention the efficiency of the electrolyzer. Alstom approached the company to supply hydrogen as it was able to bring the gas to the pressure needed for the purposes of this project. A diesel-powered truck carries the hydrogen to the train station for refuelling. An interesting juxtaposition of technologies ... But Harnois says the fuel would ideally one day be produced on site. For refueling, the full hydrogen tank on the truck is connected to the empty tank on the train, and the pressure difference causes the hydrogen to flow from one to the other. A regulator controls the flow so it doesn't get too hot. The fuelling takes about an hour. I wonder how long the predecessor train took to fuel.
