Posted By: BrianwilsonInteresting to note wheat prices reached all time high in UK last week , same time as announcement that largest bioethanol plant using 1,100.000 tonnes of wheat per year is to commence operation. Food riots reported in various Countries but UK encouraging farmers to change 60,000 ha land use from wheat production to dedicated biomass .Fuel for 21st Century at what cost?RgdsBrian

Posted By: evanIt would be interesting to know if such pellets are actually available and what is their price compared to normal compressed sawdust pellets. The energy cost will show up there if it's as bad as it sounds.
Posted By: Brianwilsonrenewablejohn- Your comment "farms still growing the same amount of wheat just the use would be different" sums up my concern. It is a question of which use should be the priority with rapid increase in food costs part due to diversion of basics into ethanol production. I do suspect the food scare scenario is part of move to push GM acceptance but with increasing population and large amounts of food being lost due to natural disasters should we be delberately diverting food into fuel tied to 25 yr commitment.I understand set aside argument has been addressed and spare low grade land is generally used for miscanthus(elephant grass) for biomass feedstock although yields apparantly disappointing.S.T. raises point of fuel security but ethanol and biomass projects are mainly being sited in port locations which points to import of feedstock, puts us into world market pressures but it is a complex subject . The plant operators indicate preferred use of indigenous supply but surely bottom line is cheapest source which questions any hope of price stability for farmer.Probably I am just missing something again.

The energy cost will show up there if it's as bad as it sounds.Energy cost wise torrefied wood is easier to pelletise than wood pellets as the material is more friable. As it is a direct substitution to coal it will be marketed at a similar price to coal. I cannot see it being available on the domestic market in the near future as the interest generated to date has been with commercial installations who have coal fired boilers who want a renewable solution without having to install a new wood pellet boiler
