BALTIC STATES SEMINAR ON BIOENERGY
Laulasmaa, Estonia
28 June 2007
BIOGAS
DEVELOPMENTS IN
FINLAND
Ari Lampinen (lampinen@kaapeli.fi)

Share of RE of TPES = 24,1 % (in 2006)
Share of hydropower + industrial wood waste + domestic firewood =
23,4 %
Share of all other RE = 0,7 %
Share of biogas = 0,1 % (0,97 PJ)
Government biogas target 2025:
8 fold increase to 8 PJ
(0,5 % of TPES)
Biogas potential in Finland

POTENTIAL OF WASTE BASED BIOGAS =
3 % of TPES (current use 3 % of the potential)
POTENTIAL OF ENERGY CROP BASED
BIOGAS ( / Mha) = 7 % of TPES (current use
0 % of the potential)
Current biogas use 1 % of total potential

Amount of plants (and diffusion)
пЃ® Landfill gas plants: 33 (diffusion 100 % in active
landfills, 0 % in old landfills)
пЃ® Municipal wastewater treatment plants: 15 (3.6 % of
416 municipalities)
пЃ® Farm plants: 7 (0.01 % of 70000 farms)
пЃ® Industrial wastewater treatment plants: 3 (< 1 %)
пЃ® Co-digestion plants: 4
пЃ® TOTAL: 61

Total production 63.9 Mm3 biogas = 32.6 Mm3
methane = 100 million bus km = fuel for 1000
buses
Flared 27.9 Mm3 biogas = 14.2 Mm3 methane =
43 million bus km = fuel for 430 buses = 140 %
of Helsinki city bus fuel needs
Not used in buses or waste trucks, not even in
the existing fleet of over 70 methane buses (that
use natural gas pipelined from Siberia)
Efficient use of energy and exergy
of wastes at Kalmari farm
пЃ®
Co-digestion of cattle dung, agricultural waste,
kitchen waste, industrial waste and energy crops

Co-production of electricity, heat, traffic fuels and
fertilizers (polygeneration, biorefinary)
Payback time a few years without subsidies
Micro-CHP: 30 kWe + 60 kWt
(modified Valtra tractor engine)
Vehicle refueling facility

Waste based biogas has the lowest lifecycle
greenhouse gas emissions of all traffic biofuels,
incl. all the so called 2nd generation biofuels
CO2 emissions: One Toyota Prius hybrid
emits as much as 10 large biogas Volvos

Conclusions
пЃ®
пЃ®
пЃ®
Large (100-fold) potential to increase biogas production
Main success landfills due to environmental legislation
Very low diffusion of biogas technology in all other sectors,
where legislation does not favour the biogas option
пЃ®
New EU waste directive, draft COM(2005)667, enables changes in
this aspect; a proposal in Finnish is available at
http://www.kaapeli.fi/~tep/projektit/ilmastonmuutos/Jatelaki_aloite_TEP150607.pdf
пЃ®
Most advanced technology available from Finland (BAT and
BEP for dissemination to other countries) = farm scale
polygeneration of traffic fuels, electricity, heat and fertilizers
пЃ®
Also possible as Kyoto JI projects like the Paldiski/Pakri 18.4 MW
