Agro-energies in Luxemburg

• Important Agro energies in Luxemburg
• Naturally growing raw materials (seed flax,
  grain, wood, corn)
• Biogas
• Solar energy
• Wind energy

BIOGAS UN DER ATERT soc. coop.

• Beginning of the production in 2001
• Realization of the entire project in 2003
• Starting of bio-methanisation September 2003
• 29 farmers
• 3 employees

8

• Dimension
• 3 préfosses
• 3 digesters of 1000 m3 and 3 post-digesters of
  1000 m3
• 2 storage tanks of 1900 m3
• 10 tanks for decentralized storage of 21 000 m3
• Force
• Gas motor of 500 KW
• 2 dual-fuel motors of 100 KW
• Extension to 1300 KW in progress 3 motors of
  265 KW that will take over the work of the small
  motors

9

• Resources
• 2950 UGB, 31000t/year of liquid manure
• and 7000t/year manure
• Corn 5000t/year
• Tons of lawn and grass silage 4000t/year
• Energetic plants 1100t/an
• Bio-digest Production
• 41200t/year spreading by injection

10

• Energy production
• Average of 3,6 millions of m3 biogas a year
• Electricity 5500MWh/year
• Total calorific energy 6400MWH/year of which
  2200MWH/year are distributed via a heat network
  of 800m to the swimming pool
• Connections to the new High School of Redange and
  its gymnasium in progress

Natural gas Kehlen (soc.coop.) (1/2)

• Agricultural Biogas installation with
  co-fermentation (still under conception)
• Owners and operators 30 Farmers (Union)
• Fermentation (wet) with gas production following,
  which means no electricity
• Processing of the raw biogas 55 Methane
  converted to natural gas quality, i.e. at least
  98 CH4
• Feeding into the existing natural gas network
  (medium pressure)
• Gas processing via wet gas cleaning (500 m3/h)
• Separation of the fermentation rest substrate
  (firm-liquid-separation)

12
Input materials (2/2)

• Agricultural input materials
• Slurry (semi-liquid manure), Manure from
  participating farms
• NaWaRos (herb and corn silage,
  GanzPflanzenSilage (silage of entire plants),
  Cereals, ...)
• Input materials not coming from agriculture
• Biological waste and plant waste from the local
  community
• K3 waste, i.e. so-called waste from food
  production (e.g. Dough ware) as well as from the
  food chain (e.g. expired food)

K3 waste has to be hygeninized, following EU
rules (70C during 1 hour)? uses a lot of energy
and is expensive!!
13
Subsidies for renewable energies from 2008

• Solar energy 30 of the acquisition costs up to
  30 KWcrête
• Wood burner for heating 30 of the acquisition
  costs up to a subvention maximum of 4000
• Biogas installations are supported with 50 of
  the acquisition costs
• (Subsidies of New Agriculture Law)

14
Prices for feeding in are valid for 15 years

• Electricity from solar energy 0,42cent/kW
• Biogas
• From 300 to 500 KW 0,13 Cent/KW
• From 501 to 2500 KW 0,12Cent/KW
• If proof for selling of Heat is shown, an extra
  Beim Nachweis des Verkaufes der Hitze Extra
  premium of 0,3 Cent/KW

15
Conclusions

• Accelerate research activities
• Cut down subsidies for lowering the price of the
  feeding in
• ( This makes it easier to cover running costs)
• Make it easier to use waste for Biogas
  installations
• More profit from feeding in
