Economics of Producing H2 From Crude Glycerol?

06/07/2012 7:50 AM

Can someone advise on the economics of this compared with making H2 from natural gas?

The biggest problem I have is that, though the advisor to the project has experience in setting up a medium scale biodiesel business, he is fixated about this venture focusing on making hydrogen from the crude glycerol (It will be a completely separate business this time, disposing of the glycerol from small biodiesel outfits in the area).

The project is only at the stage where financing is being sought, so I want to ensure that we have the most robust model possible to take to investors.

The other, possibly bigger problem as I see it, is that not only is H2 the only product that he recommends to produce (even though many other more value-added and transportable products also have potential) but he is pushing the idea that the H2 will be immediately consumed in a fuel cell (further large expenditure up front!) rather than considering if it's more valuable as a feedstock.

Thanks kindly for -all- the links, but particularly the economic feasibility pdf.

To me it seems fairly touch and go whether enough high quality H2 could be made to even cover the running costs and service loans, let alone turn a profit on the sort of scale plant that we would be devising.

Would I find support here for the view that deriving electricity (via a fuel-cell) that would simply be pumped into the grid would return even less value than the hydrogen (even if a 'green' tariff offset things somewhat)?

I can see it might be a different story if the set-up was purely run as a back-up generator (for a server farm for example) or for a remote community that otherwise would use Diesel generators but in a developed metropolis I can't see how it stacks up.

I don't see it as viable for electricity production.

Check these guys out. They're using antifreeze to make cutting gas.

Thanks. Most interesting.

Anti-gelling agents and MTBE-like products are also possible and a better ROI than H2 can offer IMO.
