CSIRO needs to give out more info on bio-crude to see if it really is amenable to processes like fractional distillation, cat- and hydro- cracking. Other pyrolysis oils have over 10% water plus unhelpful fractions akin to vinegar. I think we need not just bunker type fuels for ships and generators but premium fuels for our PHEVs. Or maybe there will be a split; black goo for stationary engines (eg for wind backup) and low EROEI ethanol for range extended plugin cars.
I wouldn't get too excited about this and I don' think you'll get too much from CSIRO until the patent is at least filed.
Waht amazes me is the way these boffins consider anything not immediatley consumed as waste. Agricultural stubble plays an important part in leaving some organic matter in farm soils, which halps reatin moisture and feed essential micro-organisms. Forest wastes also are valubale environmental products that have a palce in the forest cycle.
I wouldn't necesarily object to landfill waste extraction for ligno-cellulose, if methane production from the same waste was not considered a higher EROI. We might make enough diesel at least to keep the garbage trucks going.
