BYW, they might want to pick a seed with higher oil content.

Todd, when I was a student in this department there was quite a bit
of work being done on the pyrolysis of coal. I suspect this is what
they are talking about in this paragraph:
Waste pyrolysis oil is currently burned as fuel, but this can be
quite polluting, said Dr Dupont. Our system would still make use
of its energy potential, while allowing the often noxious chemicals
in the oil to be more easily controlled.
i.e. 'waste' oil from a totally separate process, not the co-product
of the steam reforming of sunflower oil.

All a bit elusive... quote:
Most methods of producing hydrogen burn another fuel for energy,
which itself creates pollution - carbon monoxide, nitrogen oxides
and other emissions, said Dr Dupont. Our catalyst uses oxygen
from the air to heat up naturally, and this heat is used to
reform the oil with steam to create hydrogen. The excess carbon
dioxide is taken into the second catalyst, then released for
storage or use in other chemical processes, ensuring that
damaging levels of CO2 aren't just put back into the atmosphere.
Oxygen from the air to heat up naturally... Interesting. I
wonder what their loss rate of catalyst, or energy cost to
restore it if needed, or life cycle energy cost to refine it.
They mention pyrolysis in a latter paragraph. Wonder where they
get the damaging levels of CO2? If they were using the pyrolytic
fuels from the process itself to perpetuate stripping (not
creating) hydrogen they would be carbon neutral at worst, erego
no damaging levels of CO2. Not to say that CO2 recovery is not
intelligent, as it could be used to produce methanol as a useable
byproduct, among other things.
