Sapphire Energy turns algae into ‘green crude’ for fuel
I suspect we are going to be seeing more and more of stories like this one. A newly formed company says that is can produce “green crude” using algae, CO2 and sunshine, and that it is three years away from commercial production at costs comparable to “artificial crude” from the tar sands.
I have no idea of the veracity of any of this but I notice that the people interviewed are cautious as opposed to optimistic: they want to know what the greenhouse gas effects of the entire process are, probably due to being bitten by that issue by other biofuels. Then there is the question of tailpipe emissions. If it is just like the fuels we use now in that respect, then perhaps local air quality will suffer. So it’s not a magic bullet. And of course there are other promising technologies too. One of the great things about $135 per barrel oil is that a lot of people now have some real financial incentives to get creative.
