Biofuel made from power plant CO2
snip
GreenFuel has so far received more than $18 million in venture
capital
funding, and hopes to install a full-scale algal farm at least 1
kilometre square near the Redhawk plant by 2009. Berzin calculates
that
if the farm has enough algae to absorb all the CO2 produced by the
1000-megawatt plant, GreenFuel could ultimately produce more than 150
million litres of biodiesel and 190 million litres of ethanol a
year.
To
do this, it would need a farm of between 8 and 16 square kilometres.
Something wrong with the sums here surely. The most gross solar input that you could get is 1kW/m^3 * 10^6 m^3 = 1GW if you're near enough to the equator, and if you include all the visible wavelengths.
I don't see how you're going to convert the CO2 from a 1GW plant with that!
Have I missed something?
I had read it as if he were comparing it with conventional biomass farm.
But still I'm sceptical.
