    ...about using hydrogen as an energy source. A lot of people touted it as a replacement for natural gas. It's not, as it has a much lower caloric value, and will react with metal piping, leaking where natural gas wouldn't. You need special piping and tanks for hydrogen, and if you use it in fuel cells, you can't add odorants and colorants to make leaks apparent, as they will poison the catalyst. Otherwise, hydrogen fires are almost colorless, and leaks will definitely be odorless.
