OK, yet another super 'techy' word that means nothing to almost all of us as reported in the Telegraph today. This one, however, just may be a word that comes into common parlance over the coming years and decades.
So what is it? Electrohydrogenesis is a process from which "efficient and sustainable hydrogen production is possible from any type of biodegradable organic matter".
Scientists have "devised a method of hydrogen production that relies on combining electron-generating bacteria and a small electrical charge in a "microbial electrolysis cell" to belch out hydrogen gas."
The scientists' "reactor generated hydrogen gas at efficiencies up to 99% of the theoretical maximum yield. 'This process produces 288 per cent more energy in hydrogen than the electrical energy that is added to the process'."
Now that is some claim. If validated, this just may represent a realistic way forward for the generation of hyrodgen as a genuine fuel source. Maybe they have even located the holy grail of the 'hydrogen as a fuel' research arena?

Addendum:
Much as I like the concept of Hydrogen powered vehicles, providing, of course, that the Hydrogen itself can be produced in an environmentally acceptable and safe manner, I have to seriously question the enviROI of this from Reuters, reporting on an order for 10 hydrogen powered buses for London.
Sorry, but at a million pounds each [What the **!!!!!] I'm sure that there must be far more important and urgent things, with far more viable enviROI's for this sort of dosh to be spent on!
