[Digestion] High costs of biogass plants in Norway

Sat Dec 4 00:28:07 CST 2010

Hi all,

Footprint and insulation are two parameters we also have to take into
account in Mauritius. Footprint is of utmost importance, generally
speaking in small island development states (SIDS) land shall be devoted
to crops or buildings, thus energy making processes requiring an
extensive area are not convenient although of a low technology ... In
tropical SIDS, mainly poor or emergent countries, with a high dependency
to  fuel importation, the problem is not to insulate tanks within AD
plants but to increase as far as possible the energetic productivity of
digested organic material, because of a limited amount. Therefore we are
working on compact, thermophilic and auto thermal plants.
One of our very simple findings is that a significant part of kcal
needed to heat or sustain the thermophilic phase can easily be produced
with thermal solar panels set on the roof of tanks. One another
technological track  we are following is to differentiate the primary
hydrolysis phase at a mesophilic stage with increased HDT, from the
acidogenic, acetoclastic  to methanogenic phase (all in one) at
thermophilic conditions. This way of thinking is linked to the fact that
considering the few organic input we have to deal with, co-digestion
seems necessary and leads us to experiment some "strange" blendings ... 
I will be interested to share on this, even if related to non tropical
contexts !

HI Harold, 

I wanted to mention that Europe is dominated by insulated tank
digesters, common in Germany, that come at a very high cost.  We have
presented proposals for lagoon digesters that have come in literally 10
times less expensive than competitive bids for Euro-style systems.  I
have done work with RCM-Digesters International, who specialize in these
lagoon digesters, and have installed them in areas of extreme cold
weather.  I am confident that these will always come in less expensive
than the tank-type systems.  The benefit of the tanks often includes the
use of less space (more of an issue in Europe than the U.S.), but that
may not be an issue in Norway.  RCM would be willing to examine a
project of this nature if it were more than just one system.  Let me
know if you want me to facilitate.  

Best,

Alex

        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
