HI Bob,
 
The turf we looked at in Ireland is a very early stage of browncoal, and yes its a more solid state than hay or grass, greetings Martin

No Martin, turf as in sportsground surface may be pressed grass but turf a la the Emerald Isle (dunno 'bout Russia) is very definitely not. It is the early stages of coal, in fact it is a brown coal. To describe coal as pressed grass is stretching the category a bit, by a few millions years I'd guess.
Regards,
Bob.

In Europe a lot of the energy plants use TURF which is of course pressed grass, (Ireland Russia) in Scandinavia they use in threre roastbedfurnace pellets comming from Holland made from waste; chopped plastic, textile, wood, paper, board, etc, (solid fuel) these pellets reach the calloric value of coal and are replacing the coal in the furnace.

Does anyone have any additional information on grass as a bio-fuel and the conversion into pellets as the site below suggests?  The site does not have much detail information (capital investment, process, market, etc).
 
It looks interesting!!!  Any thoughts?
 

The best thing about this Cornell web site is the 'Demonstration' page, which summarizes a set of experiments with burning grass pellets in various real stoves and furnaces.   The issue involved is the fairly high ash content of cool season grass. 

Canadians have researched this subject of burning grass pellets.  Do a Google search on "switchgrass pellet stoves canada" and you will find some of their web pages.

You should be aware that grass is being burned in some coal-fired electric power plants.  Up to 10% grass is burned with the coal.   Currently a power plant near Ottumwa, Iowa is running a trial of this idea; they burn 2.5% switchgrass, in the form of  big bales.    I am aware of another power plant project which will use pellets.
