Capturing or otherwise neutralizing the CO2 must be done safely, says Stephen Wallace, who runs a microbiology lab at the University of Edinburgh. But he adds that Cemvita Factory’s idea of harnessing microbes for hydrogen production is “indicative of a lot of the really interesting work going on in biotechnology right now.” Wallace and his colleagues are themselves experimenting with bioreactors and have had some success in getting microbes to yield hydrogen from things like moldy bread or the lignin in paper industry waste.
But while some microbes help produce hydrogen, others are the scourge of these projects, as they can eat up stored hydrogen or consume the gas in natural wells, says Jon Gluyas, a geologist at Durham University. “We’re trying to keep bacteria away from our hydrogen because they love feasting on it,” he explains.
And he has another quibble. He argues that “gold hydrogen” is different
