Plug Power has just has received a follow up order of 120, for its GenCore backup fuel cell systems, from IST Holdings Ltd.

In his 2004 book, "The Hype about Hydrogen" Joseph Romm said "Price and payback trump almost everything else" - the insight I think of a true sage. In other words, while companies "... say they would like more reliable power (such as fuel cells), the vast majority are not willing to pay very much more for it".

2 years on, fuel cell sales are starting now to come through and this industry is starting to go places. Still, how many companies would choose to pay much more for fuel cells as an uniterruptible power supply over an advanced flywheel or even an off the shelf diesel generator?
