For those of you who struggled with high school chemistry, this one's a doozy.
I wrote about the Kia Sportage FCEV in Part 1 of this story. Kia is owned by Hyundai, and both are located in Korea. Kia is supposed to be the slightly lower-end and sportier mate to Hyundai's marginally higher-end and luxurious vehicles. So, it is no surprise that they share hydrogen R&D costs and technology.
I mention in most of my posts on hydrogen that it is very early in the development stage, that hydrogen is an energy carrier, not an energy source, and that it takes more power to produce hydrogen at this point than you get out of it. These facts are not enough information to give up entirely on hydrogen for use in automobiles, as evidenced by the recent progress of fuel cell vehicles in Korea.
