 I'm enjoying Hawaii's warm ocean breezes as I wait for my ride with Mitch from the Hawaiian Natural Energy Institute in a cleaner missions vehicle fueled by hydrogen. H&EI is providing the hydrogen infrastructure used to fuel this car. Mitch, if you could just tell me what the essential elements of this car are, to propel it. The essential element starts with the fuel cell, which is up under the hood where the engine used to be. It combines hydrogen, which is stored in the car, and hydrogen tanks. Oxygen from the air, produces electricity, and that drives the electric motors. We call it a fuel cell because you have hydrogen on one side, and you have oxygen on the other. It's like a battery. What you have here is a zero emissions car. Can you explain to me why that is? Yes, the chemical reaction between the hydrogen and the oxygen produces pure water, absolutely pure water. Our Marine Corps-based hydrogen station is the first really dual fuel, fast-fill hydrogen station in Hawaii, and we learn a lot about what it takes to put in a hydrogen fueling station here in Hawaii, which we can transpose that to industry. So you can see the fueling station just coming into view here on the corner. The whole idea is to make this for the consumer to be able to have the same experience they have as going to a normal gasoline station. Seeing the hydrogen dispenser as we approach, I can understand what Mitch is talking about. The setup looks very much like a conventional gas station. The first thing Mitch wanted to show me was the electrolyzer, the heart of the fueling station, where electricity produces oxygen and hydrogen from pure water. The oxygen is vented to the atmosphere, while the hydrogen is fed to pressurized storage tanks. And what would you say, is it like one of these to a complete refueling of the car? Approximately one of those. The car takes four kilograms and each one of these tanks holds about four kilograms of hydrogen. The fueling process requires the hydrogen from the storage tanks to be compressed to 10,000 psi, so that sufficient hydrogen can be stored for a range of 300 plus miles per refueling. That makes the HNEI Experimental Fueling Station an autonomous producer and dispenser of hydrogen gas, all on the same site. Almost like a gasoline dispenser, it locks on. I just hit the start button here, and you can hear that first puff of hydrogen going into the line. It's doing a check. Yeah, oh, to make sure they're all as well before it actually pumps the hydrogen. Filling up from empty takes less than five minutes, and we're quickly on our way. As Mitch drove me back to my gasoline-powered car, I could now understand why the hydrogen fast fuel concept is a major step along the road to an emission-free hydrogen-powered future.
