Reed canary grass as an energy crop Håkan Örberg Unit of biomass technology and chemistry

Reed Canary Grass research at SLU/BTK Establishing crop Crop treatment Harvesting and transport Storage Upgrading to Briquettes and pellets Combustion

Perennial rhizomatous Grass Reed Canary Grass A high yield crop in humid areas Resistant to diseases and damage by insects Establishing by seeding Agricultural machineries can be used by harvesting and seeding

Delayed harvest of Reed Canary Grass 1. Washing by winter rain gives lower K and Cl contents 2. Harvest in early spring time gives dry material % water 3.High losses

Regions in screening trails

Yield of delayed harvested RCG in Northern Europe

Fertilizing kg/ha Year 1+2 N P K Year 3-10/year Based on a yield of: 7500 kg/ha

Harvesting studies Harvesting methods Combination of machineries Capacity measurements Defining period length of harvest Defining yield and losses Defining d.m.values

Storage studies Different cover methods Different stacking methods Time consumption Cost calculating

Upgrading to pellets or briquettes Capacity and quality measurements Electrical consumption measurements Optimizing processing parameters: - Grinding, sieving, steam conditioning - Die type System analysis
