What happened to the hydrogen vehicle?
Can you tell me whatever happened to the hydrogen vehicle? It was a big topic a few years back, but I haven't heard much about it lately.
Hydrogen vehicles are still being researched and developed, but they haven't yet become widely available to the public. There are a few reasons for this. First, producing the hydrogen fuel itself can be expensive and energy-intensive. Second, there aren't yet widespread refueling infrastructure for these vehicles. However, some automakers like Toyota, Honda, and Hyundai continue to work on perfecting this technology.
