[Digestion] High costs of biogass plants in Norway

[Scholwin, Frank]

Hej Harold,

we are regularly analysing the biogas market and unfortunately see exact this development you describe. The prices did raise within the last 5 years by more than 50 %.

But only taken from your figures the calculation seems to be really above also actual market prices. If you could send me some more information about the calculation of a single plant what is the basis for the large calculation for your country  I could make my comments. When I take your 100.000 t – plant I would assume that (when you would generate electricity) investment costs would be in Germany when you construct no special treatment of the residues, no new storage for the residues for the winter time and when you generate electricity without gas upgrading and if you use cow manure about 5-7 Mio € (electrical capacity about 900 kWel). Adapted technically to very cold regions of your country probably 10 to 20 % higher.

So far best regards
Frank

Betreff: [Digestion] High costs of biogass plants in Norway

Hello all
Our Agency - Climate and Pollution Agencu made in 2010 a study of measures in the Agriculture sector to curb the emissions of climate gases. The production of biogass from manure was one of them, with reductions of methane and N2O from the storage of manure as well as a potential to reduce the emissions of CO2  by substitution of fossile fuels. Our consultant provided us with costs for the building and running costs, much higher than any other country in Europe, included neigbouring Sweden and Denmark.
For plants with capacities to treat 50 - 100.000 tonns of manure the following figures were given:


4.3 million tons of manure/year (about 30 % of the total amount of available manure) representing manure from farms in areas with a relative high density of animals:



Biogassgeneration: 710 GWh/year

Investment= 4.3 billion NOK = 540 million €

Cost of Capital = 350 million NOK = 44 million €/year

Transport, labor, maintenance and electricity; 215 million NOK = 27 million €/year





Investment 126 €/ton manure annual capacity

Cost of capital; 10 €/ton manure

Cost of labor etc:  6 € /ton manure

 Sum: ca 16 €/ton



Plant 100.000 ton manure/year:

Investment : 12.6 mill €

Capital + other cost:  1,6 mill €



Compared to the figures below, they are 60-100 % more expensive, even without assumed electricity generation.



Knut Hjort Gregersen (2005) Centralised Codigestion Plants in Denmark - Present situation and future perspectives. Bioenergy 2005, Trondheim, Norge:



Plant with annual capacity of 110.000 m3



Investment: 55 euro/m3 annual capacity

Cap + other cost: 10 €/ m3 behandlet



One of the possible explanations which is given, is that manufactorers from Central Europe are not very interested in the Norwegian market - low potential and calculate with hig costs in their bids.



We would like your view points on the given figures; do they seem reasonable?

Would manufactorers lower their prices to a "european" level?

These high costs made the measure "Biogas" very costly"  in relation to the obtained emission reductions, even when taken in consideration other benefits.



Looking forward to your comments



Harold Leffertstra
