LogistEC storage experience
• Content
– Storage expertise in operation conditions of EC
• Triticale: Plastic cover vs indoor structures
• Poplar: whole tree vs chips
– Tests with new biofuels
• New crops
• Pre-treated feedstocks

LogistEC storage experience
• Different plastic cover alternatives
4
-
LogistEC storage experience
• Reduces raw material loses
• No very expensive
• Versatile: different solution according the storage configuration
5
• Difficult to built up the plastics cover – No wind
– It is necessary a lorry with a crane
– Risk of accidents
• Possibility of leak formation
Plastic covers advantages and disadvantages
-
LogistEC storage experience
• Indoor storage
6
• Weakness: cost, …but if
• Storage cost indoor: around 7 €/t
• Save: 12% of the storage straw
• Straw price: 55 €/t
Then, economically feasible
-
LogistEC storage tests
• Grassy Biomass Triticale. Start date: 7/05/2014
(Storage test currently in progress) – Bales outdoor
– Bales outdoor cover by plastic
– Bales indoor
– Briquettes outdoor
– Monthly Control : Weight NCV, Ash content, moisture content, elemental analysis.

LogistEC storage experience
• Objective : compare different storage systems
• Staked Logs
• Pile of chips
• Storage during 2014
– Storage demonstration: whole poplar logs stacked – Storage place: a plot near the plant, over a soil floor
– Storage demonstration beginning on: 20/12/2013
– Total biomass harvested: 239,8 t (47% moisture content)
– The height of the poplars : 6 or 7 meters.
– Diameter minimum of 8-9 cm up to a maximum of 12 to 13 cm.
– Parameters controlled: Moisture, NCV and ash
– Pending task: Storage of poplar chips 2015
