IdaTech Plc, (since when did it become a great branding idea to place capital letters in the middle of company names?) successfully floated on London's AIM a couple off days ago. The company is currently priced above it's IPO price - pretty good considering current market conditions and that this industry is far from flavour of the month. Investors have after all, lost lots of money in fuel cells over the years.

IdaTech, founded in 1996, was acquired by IDACORP in 1999. IDACORP latterly sold IdaTech to Investec in 2006, since when there has been a steady deal flow and series of press releases. Investec, incidentally, even use IdaTech's fuel cells as backup in their HQ.

IdaTech's major USP has to be its use of methanol mixed with water as a hydrogen fuel source for the reformer, engendering longer run times in emergency backup situations.

Still, for anyone who wants to read the sceptic's case against fuel cells, I highly recommend Joe Romm's Hype About Hydrogen, a book I've mentioned a few times here before.
