Burning wood (pellets) on a large scale!!!!!

[cessna]

There was a programme (Mega Shippers) on Quest TV this evening,which did a feature on shipping wood pellets from Louisiana to Immingham docks,and on to Drax Power Station . I am sure the guy at Drax said they use a 1000tonnes of wood pellets (ground to dust) an hour !!!!!!!!!!!!!!!!!!!!

How sustainable is that ???????????

Please correct me if I am wrong.

1000 tonnes/hour is about 5GW of thermal input, at 35% conversion to electricity That gives about 1.75GW electricity out. We peak about 50GW on a winter evening.

once the shipping is taken into account the co2 is higher than coal

I doubt it shipping in bulk is very energy efficient, have you a cite to show the energy cost incurred in transport from US to Drax?

 

We once did a costing on hauling wood, for energy, from Surrey to Didcot, it worked out less costly than sending electricity the same distance.
