Wow no kidding. This is why I think the mfr's are not pushing the envelope, presumably due to safety and reliability. As for high load, that what I was just beginning to understand, after seeing a chart that shows no appreciable performance change, until right at peak, and then an additional 15% hydrogen adds a boost, for about 8% improvement in efficiency. I've always thought it was a scam, but now I'm seeing a small window for some kind of claim. And yes, large volume gas production costs way too much electricity, so you would want to build it up and store it. That would seem to contradict the mileage claims though, because you'd be robbing Peter to pay Paul.
