I've mentioned before that in Japan they are using natural gas fuel cells for household electricity.
On Saturday Extra on Radio National this weekend, they were talking about an Austalian company which is developing them too. There is no transcript available, but you can listen to it on streaming audio here. (It starts about half way through that segment.)
The link to the company itself is here. I don't think it is not mentioned on their site, but was in the interview, that it is CSIRO research which the company is trying to commercialise.
We won't be seeing them anytime soon in Australia, however. According to the interview, they are being commercialised for the European, Japanese and North American markets. This is because the cost of electricity here is such that they are not yet cost effective.
