Pellet plantsin Europe 2003

Enormous development in biofuel productionis now taking place. Almost every week newor upgraded pellets plants are presented on

the market. The result of this development is theexistence of a number of really small as well as verylarge pellet plants. The map and the following list indicates the pro-duction sites of commercial pellet fuel. We haveused different sources including our own questionn-aires although around 25 per cent of the presentedinformation are based on the indirect source. Thereare a few dots on the map that are not mention inthe list. We have also included the harbour of Rot-terdam as symbol for the overseas distribution ofpellets, so far mostly from Canada. For more information please visit our websitewww.bioenergyinternational.com and we appreciateupdating info for upcoming presentations.



Bionorr goesfor 140 000tonnes/year

The large Swedishpellelts producerBioenergi i Norr-

land AB, Bionorr, is dou-bling its capacity upto140 000 tonnes peleltsper year in their plant inHärnsöand, 500 kmnorth of Stockholm. Theproduction replaces aro-und 65 000 m3 heatingoil that has been usedeach year.

The plant is owned byone o the largest forestry

industries in the worldSCA. Their main activi-ty lies in forestry andproduction of timber,pulp and paper world-wide.

New investment of6.5 million Euro is fol-lowed in Härnösandright now. Two moreSprout Matador’s - 5 t/h- presses are installed to-gether with their ownpatented milling dryer.

Now the pellets plant

is equipped with 5 pres-ses, two mill-dryers andlarge storage facilitiesfor the products whichare delivered mainly inbulk but also in big orsmall baggs. The bag-ging equipment forsmall baggs is deliveredby Dansih Fisker PakkeMaskiner A/S.

The heat for the dryeris provided with wood-powder burners fromSwedish VTS Värmetek-

Pelletsproducers

nisk Service AB.Sixty five percent of

the production is delive-red to the large scaleusers, such as districtheating plants, located-mainly in the Stockholmarea. Pellets are trans-ported using vessels andtrucks.

An increasing share isdelivered locally to smallhouses and medium sizeheating centrals.

Kent Johansson, ma-

nager of the plant has 22employees helping himwith the production andadministration. Thenext step, he says, is toarrange a better rawma-terial handling system.Today the sawdust thatis used for the pellets-production is handledby a frontloader.

The pellet plant inKøge south ofCopenhagen is

starting up it’s produc-tion. On a yearly basisthe plan will produce130 000 tonnes of strawpellets and 180 000 ton-nes of wood pellets. Thestraw pellets will betransported on ships andused in the Amagerplant, an old coal firedplant. The wood pelletswill be used in the newand advanced Avedøreplant.

Energi E2 is the ownerof six heat and powerplants that use 445 000tonnes of biomasss an-nually. Calculations hasshowed that the cost forusing dry biomass isonly one third whenusing existing plantscompared to build newplants for biomass.

The pellets plant hastwo production lines,one for straw pellets

with a capacity of 17tonnes per hour and onefor wood pellets with acapacity of 30 tonnesper hour. The twelvepresses from Bühler willrun 6000-7000 hoursper year and produce intotal 310 000 tonnes ofpellets annually.

Most of the process isbased on known andproven technology. Thedryer from GEA will re-duce the water contentin the wood from 45 percent down to 10 percent. The dryer will usesteam from the existingpower plant. In the pro-cess 85 per cent of theenergy in the steam fromthe dryer is recovered. Inthis way only a few percent of the energy con-tent in the pellets is usedin the production pro-cess.

The straw pellets donot need any drying be-fore pelletising since the

material is dry as it is.From the pellet plant

the pellets are transpor-ted on a 700 meter con-veyor to the storage inthe harbour. No adhesi-ve is used to start withbut might be used lateron.

The plant is locatedon the site of Junkers’swood working industry,producing wood floor.The existing heat andpower plant is combinedwith the production ofthe pellets. The pelletplant is located next tothe storage area for thewood industry, where50 000 tonnes of woodcan be stored. The majorpart of the raw materialfor the wood pellets isresidues from the floorproduction. To thatsome part of raw mate-rial will be imported.

Since 2002 the portof Rotterdam haswitnessed a rapid-

ly growing flow of im-ported biomass. Europe-an Bulk Services (EBS),operators of two termin-als in Rotterdam, dis-charge more than25,000 tons of biomassper month, mainly con-sisting of wood pellets.

EBS have witnessedsome very interestingdevelopments in themarket over the last twoyears:

* The growth inimports is tremendousand still continuing:from less than 5000 ton-nes per month in the be-ginning of 2002, amonthly import level ofmore than 40,000 ton-

nes is foreseen as fromJanuary 2004 onwards.

* Originally Rot-terdam only witnessedthe arrival of wood pel-lets from West Canada.Now there is a much lar-ger variety in biomass,including wood andbark pellets from USAeast coast, wood pelletsfrom the Baltic statesand various types of, so-metimes experimental,pellets from destinationsin the Far East and theUS, made from cleanagricultural residues ofcorn, rice, palm and ci-trus.

* EBS receivestrong indications thatlarge scale wood pelletproduction for export toEurope is about to start

up from South Americaand South Africa.

* Biomass used toarrive in vessels of max-imum 10,000 tonnes.Now biomass frequent-ly arrives as part cargo-es in Handymax andPanamax vessels up to60,000 tonnes.

* EBS now perma-nently store more than30,000 tons of biomassfor various internationalsellers, traders and buy-ers who use the storagefacilities for just-in-timedistribution purposesand strategic stocks.

TransshippedPerhaps the most inte-resting development,however, is the fact thatthe arriving biomass in

Rotterdam is no longerexclusively destined forelectric power producersin The Netherlands butis increasingly frequent-ly transhipped to otherEuropean destinationsas Belgium, the UK andDenmark by coastal ves-sels and river barges.

The economics behindthis development arevery interesting. It seemsthat biomass is develo-ping like many largecommodities did in thepast. Instead of onlyusing local (European)biomass and shipping itin small coastal vessels,now the users of bio-mass in Europe startbuying large quantitiesfrom overseas origins,

making use of the adv-antages of economies ofscale: the freight costsper mile or kilometer fora panamax vessel with e.g.60,000 tonnes are only afraction of the freight costsin a coastal vessel.

Biomass develop-ment in Russia

The Russian federation possessesgreat facilities

with regard to bioener-getics.

However the impetusgiven to the develop-ment of this direction isstill not enough for itssuccessful advancement.

The main negativefactors are following:

• higher earning yieldin individual industriesand mining operationsthat makes bioenerge-tics less attractive com-mercially.

• the absence of thelegislation incentive thedevelopment of bioener-getics

• the availability ofthe comparatively cheapfuel in almost all the re-gions of the Russian fe-deration

• the absence of finan-cial mechanism and loaninstitutions interested inprovision of finance ofthe such projects, highlending rates in theRussian banks and shortterms of the reimburse-ment of credit

• the fact that foreigninvestors beware of put-ting up the capital intothe Russian enterprises.

the facilities of Russianinvestors.

None of the foreigncompanies has taken adare to invest of such aproject, notwithstandingthe shown interest. Itcaused that the first en-terprises could not affordto acquire modern high-tech equipment sugges-ted on the Europeanmarket due to the limitedmeans and tight rates.

In the beginning thesecond hand agrarianequipment has beenused and this reflectedupon the quality of theproduct and on the fac-tory load.

Development of indu-strial facilities causes theincrease of the problemsconnected to the recla-mation of the loggingwaste and industrialwood residue.

In the described above situation the pellet producers made a decision to team up, in the end ofaugust the memorandum of RBA was signed. The

main objects of the association are:• adoption of the quality standards and the order

of certification of the product, the product qualitycontrol;

• the assistance to the members of the Associationin the line management, in the receipt of necessarytechnical information and advice;

• close cooperation with the scientific institutesworking in this field;

• biofuel native market grouping and promotionof the Russian product on the international market;

• lobbying of the producers interests at govern-ment level and legislative bodies;

• communications with other European associa-tions, assistance to them in solving all the questionsof the work connected to the Russian Federation;

• assistance to the members of the Association inattraction of the credits and investments.

Transport andlogistics

In view of the transportremoteness of the pro-ducers from the mainconsumers of the biofu-el and much of the Russ-ian Federation, great trans-portation charges arise.

Because of this fact allthe first plants were lo-cated in a short distancefrom the Saint-Peters-burg port, some of themwere built on the shoresof the navigable rivers

and this allows to make ri-vermarine vessel shipment.

The problem of trans-portation makes the re-mote forest regionsunattractive for biofuelproduction. It wouldbecome possible onlywith the development ofthe international trans-portation corridors,more consistent attitudeof the governmenttoward the reclamationof the logging waste andappearance of the nativebiofuel market.

Pre-treatment of rawmaterials

To achieve efficient pelletingthe raw material

moisture content mustbe reduced to approx.10 percent. If the mois-ture content exceeds therecommended 10%, thematerial must undergo adrying process.

Both drying andcrushing of raw materi-als are of great impor-tance to the pellet quality.

GrindingIt is recommended togrind the raw materialsin a hammermill.

The Sprout-Matadorhammermill type Multi-mill meets the require-ments to efficient crushi-ng of both fine and coar-se particles. The ham-mermills have magnet/air separators for collec-tion of foreign matters.

Cascade mixerThe ground raw materi-al is pre-treated withsteam in a cascade mix-er before pelleting resul-ting in homogeneouspellets, as the larger ma-terial surface and openfibres promotes steamabsorption. Steam andincreased temperature

softens the wood ligninallowing pelleting to goon without binders.

Pellet millThe new generation ofSprout-Matador PM30pellet mills ensures highoutput and efficient mo-nitoring of the pelletquality. The pellet mill isequipped with a two-step gearbox dimensio-ned for high loads.

Roll tightening can beadjusted from the outsi-de during operation.

The pellet diameter isdetermined by the diffe-rent perforation dimen-sions of the die.

Cooling and finaltreatment

Heat develops in the pel-lets during the pelletingprocess. This heat mustbe taken away from thepellets before they aresifted and stored.

The pellet are cooledby ambient air flowingthrough the cooler, andfor that reason the pellettemperature will alwaysbe 5-10° C above roomtemperature.

By a frequency operated screw dry wood chips aredosed into the hammermill separator separatingforeign matters by means of an opposing air steamand a magnet (201).The hammermill (202) is working with an air flow,which optimises the grinding process and carriesthe wood powder to separation in a cyclone,alternatively a filter (300).From a pre-bin (401) the powder is dosed to thecascade mixer (403), where steam is added.The pellet mill (404) forms the pellets when thematerial is pressed through the ring die by meansof two sturdy rolls.The warm pellets are conveyed to a cooler (408)with air passage where the are cooled to a littleabove room temperature.Finally the pellets are cleaned of dust in a sieve(415). The dust is returned to the process forreuse. By Tove Isaksen, Sprout Matador.

Process controlEfficient process controlresults in high flexibilityand optimum energy ut-ilization. The energyconsumption for opera-tion of the pelleting pro-cess and steam heatingcorresponds to 2.5-3percent of the energycontent of the wood.

Biological waste and industrial and agricultural surplus products can be transformed to environment-

friendly and economical products to be used as fuel or reused in production.

Compression of biomass through pelleting results in essential increase in the density of wood chips

corresponding to a rise from 150 kg/m3 to 650 kg/m3.

Together with a number of environmental advantages a considerable limitation of costs of transport,

storage and handling is achieved. The process is here descibed by one of the suppliers Sprout Mata-dor A/S, Denmark with its sister company UMT, Holland with 25 years of experience in the business.

Reliable fueldeliveries

As the share of forestchips in the fuel blendgrows, homogenousquality and reliableand timely deliveriesbecome very impor-tant. The programmehas supported net-working of indepen-dent machine entre-

Integration, a key to cost reduction

During the first four years of the programme, the annual use of forestchips has increased from 0.5 million

to 1.7 million cubic metres. This growth, ba-sed mainly on the use of logging residues fromregeneration cuttings, has created new require-ments and expectations for production organi-sations. A total of five different production sys-tems have been developed, comminution at lan-ding still being the prevailing technology.

Integrating chip deliveries with the existingtimber procurement process provides flexibi-lity and reliability. To facilitate the manage-ment of a large-scale procurement process,comminution of biomass is partially beingmoved from forest to the plant.

Logistics is becoming increasingly impor-tant, since transport distances grow alongwith the increased use of forest fuel. Processcontrol is promoted by the introduction ofbundling technology, the development ofwhich has been one of the core areas of theprogramme.

When using bundling, logging residues arebaled at site into logs 60-70 centimetres in di-ameter and 3 metres in length, which can betransported with conventional forwarders and

Efficient TechnologProduction of

Renewable energyand particularly wood- derived fuels play akey role in Finnishenergy and climatestrategies.

In order to reducethe emissions of gre-enhouse gases, theannual use of fuelchips produced fromresidual forest bio-mass is to be raisedto 5 million solid cu-bic metres (10 TWh)by 2010.

Annually, this me-ans a reduction ofabout 3 million tonsof CO2 depending onthe fuel replaced.

The Wood EnergyTechnology Pro-gramme launched in1999 by Tekes, theNational TechnologyAgency of Finland,has helped to pro-mote the use of for-est fuels by means ofresearch and deve-lopment.

Since the limitingfactor in reaching theobjective is fuel pro-duction, rather thancombustion capacity,the programme hasfocused on produc-tion technologies.The emphasis hasbeen on developingsystems for largeplants with combinedheat and power pro-duction (CHP).

Cost reduction, im-proved fuel quality andreliable deliveries havebeen essential in achie-ving the programme’sobjectives.

This requires moreinvestments in the de-velopment of techno-logy, new supply or-ganisations, and activeparticipation of pri-vate forest ownersand their organiza-tions.

gy for Competitivef Forest Chips

The Finnish Wood Energy TechnologyProgramme 1999-2003

preneurs to developlocal organisationsfor chip procurement.It has also addressedtopics such as the re-duction of moisture inchips, buffer storage,cofiring and the tech-nology for receiving,handling and blen-ding of wood fuels.

Since the mid-1990s, a large numberof heating and CHPplants have been refit-ted for handling andburning large amo-unts of various woodfuels. Today, there areabout 400 forest chip-fired power or heatingplants in Finland.

Transport is the biggest single factor of costformation in the forest chip procurementchain. That is why effective transport is animportant competitive factor. Cost savingscan be achieved by full loads and lesswaiting. IT applications have beensuccessfully used in logistics and navigation.Their usability has increased, as they can betailored to meet the specific needs of the user. The bundling

method is asolution for

boosting the large-scale use of forest bio-mass.

It is already in wideuse in Finland andhas, for example, pro-vided the AlholmensKraft power plant, thelargest biomass plantin the world, with adependable and an ef-fective forest chipproduction system.Bundling provides amore effective way tomanage and controlthe procurement pro-cess. The transport ofbiomass as bundlesintegrates industrialand energy wood lo-gistics, since bundlescan be transported bystandard timbertrucks.

www.bioenergyinternational.com Debate25 deliveriesBundling has a proven record

Timberjack has delivered 26 bundlers since2000 . Among these deliveries there are 19units operating in Finland, 3 in Spain, one in

the USA, one in Sweden, one in Switzerland and onein Italy. The delivery of the machines has been acce-lerating during 2002-2003. There have to be somereasons to this sales increase, on the contrary thanwhat is presented on the Bioenergy International No5. July 2003 issue. In the following, I would try topoint out some reasons for this increase of machinesales:

”Will wood slash bundling have a chance”?1) In Finland there have been several tests arrangedby the various research institutes. Figure 1 depictsone result performed by Finnish Forest Research In-stitute (METLA). This analysis is based on fairly lar-ge amount of measured data.

Picture 1. Relative costs of the different productionmethods.

The production numbers of bundles/h vary from15 to 35. The medium value over the year is > 20/h.The annual production can exceed 60,000 bundlesi.e. > 60 GWh. Also the energy content of the bund-le is today higher that it was in the earlier tests.

2) The terminal crushing of bundles is up to > 3times cheaper than the mobile chipping in relationto the MWh. The quality control of the fuel produ-ced is more stable at the stationary plant than in theforest.

3) When bundling method is used the forest trans-port and long distance transport is easy to arrange,mainly by the same machinery as the solid wood.This is economical and convenient. The log truckscan enter into the forest roads much better than thechip trucks. The bundling system is simple and easymethod when the logistics is concerned

4) Bundling is an environmental friendly systemthat is fully accepted by the different interest groups

5) When fuels storage is as bundles, it is cost ef-fective. The material can be kept in the forest as longas there is the need or the transportation can be ar-ranged. This way the power plant can always besupplied by the large volume of good quality fuel. Noother method can provide such a large flexibility.

6) Summer 2003 showed that the bundles fuel wasso dry that for the smaller power plants the fuel waswatered in order not to achieve to high temperatu-

res in combustion.7) For smaller power

plant the bundling sys-tem is very beneficial,because it provides ancost effective way tocontrol the fuel invento-ries. The bundles can bechipped at the terminalor at the plant by effec-tive mobile chipper.Bundle chipping is up tothree times more pro-ductive than the loosematerial chipping. It hasbeen measured that thechipper can produceover 340 m3 of chipwhen the bundles are fedin.

8) The quality of thewood energy supply canbe lifted significantlyhigher level by using thebundling technology.The long term experi-ments have shown thatthe bundles provide sig-nificantly dryer fuel thanthe forest chips. Bundlesare drying on stacks.

During the year 2003there was a survey doneby Finnish VTT of forestchip quality. As a con-clusion of this survey itwas clear that mobilechippers produced chipswith very high moisturecontent. Often the chipdeliveries included also avisible snow and ice. Asa biggest problem it wasseen that the mobilechipping is done fromthe small raw materialinventories, which couldbe under snow or rightafter the felling. All theinterviewed powerplants pointed out thatthe increasing number ofstationary crushers im-prove the quality controlof fuel.

Bundling method fitsalso very well in themodern information sys-tems, because it is easycontrol, measure andhandle. When utilizingthe bundling technologymore and new users canbe found for renewableenergy. Bundling is att-ractive and will certain-ly widen the bioenergybusiness significantly.

Germany:Improvements

for power frombiomass an-

nounced

The German government isplanning impro-

vements for the pro-duction of power fromrenewables

The actual German”law about the priorityof renewable energy”says, that the owner ofthe mains supply haveto buy power fromcertain renewable en-ergies at a fixed price.

For power from bio-mass there are threesteps of prices:

• power plants un-der 500 kW get 10,23Cent per kWh,

• power plants bet-ween 500 kW and 5MW get 9,21 Cent and

• power plants bet-ween 5 MW and 20MW get 8,7 Cent.

Beginning with Ja-nuary 2002 these pri-ces are falling eachyear by 1 % for newplants.

Higher guaranteeprice suggested

The recently announ-ced plan to changethis law says, that thefixed price for powerfrom biomass will risefor small power plants.

Up to 75 kW 12,5Cent and up to 200kW 11,5 Cent.

BonusBesides there is sche-duled a additional bo-nus for using naturalbiomass like plantsand the excrements oflivestock.

Up to 500 kW theplan is to pay a bonusof 2,5 Cent.

And last but notleast there is a bonusof 1 Cent planned forusing certain innovati-ve technologies.

In May 2003 Finnforest Corporationand Wärtsilä Biopo-

wer signed an agreementto deliver two BioPowerCHP plants and one Bio-Energy plant for theVilppula and Renkosawmills.

The plants are up andrunning before the endof the year.

Track recorddecisive

This breakthrough wasthe result of trust, feasi-bility, technology and

environmental values combined with innovativeplant concepts. Finnforest Oy bought the first Bio-Grate technology from Sermet already in 1994. To-day with those new orders the number of BioGrate-plants is totalling seven, five of them operating at fullsatisfaction of the owner and two under construc-tion.

Finnforest is a foregoing wood product companywith a 1.8 billon Euro turn-over and about 7500employees. Finnforest are present in 21 countries andthey belong to the large Finnish Metsäliitto Groupas its mechanical timber processing arm.

Towards self sufficiencyThe recent history of unexpected energy price deve-lopment was one of the reasons for Finnforest’s de-cisions to control that cost and produce the energythemselves.

Heat & PowerBioPower forFinnforest´ssawmills

Besides the main product, which is 600 000 m3 oftimber, the mill produces almost the same amount ofchips and saw powder for fibre production and over300 GWh of bark which is most feasible to convertinto energy at the sawmill.

Vilppula sawmill is one of the largest in Europeand they process around 1.35 million m3 of spruceevery year, which roughly correlates to 140 truck (18-weeler) loads every day, year around if all timberwould come on trucks. To handle, cut and dry suchamount of wood they need not only the latest cut-ting technology but also reliable power and thermalenergy. In fact, their energy bill is around 2.5 % oftheir 120 million Euro turn over and it is clearly thelargest production cost item after timber purchase.

CHP for the sawmill - heat forthe community

The new plant with BioPower 5 and BioEnergy 9 willconsume 180 GWh bark annually, which is around60% of that total bark production and convert it to22 GWh electrical and 132 GWh thermal energy.This covers 70% of the mill’s electrical consumptionand 100 % their thermal energy need for drying thelumber and heating a nearby Vilppula town with 5000 inhabitants. District heating energy sales bringsvaluable additional income and thus improved thefeasibility of the project.

Fast delivery on all marketsBoth BioPower 5 and BioEnery 9 plants are schedu-led to be in full production this December and theywill be handed over in the beginning of 2004. Withthe same schedule Wärtsilä Biopower is constructinga BioPower 2 CHP plant for Finnforest´s Renko saw-mill.

Reducing the risk of fire and explosion

AndersBergström,Firefly.

Identifying and cooling hot particles in abiomasss fuel hand-

ling system can preventfire and explosions.

Bioenergy Internatio-nal looks closer on how itcan be done in practice.

Using biomass materi-al is combined with acertain risk of unwantedfire or explosion. This iswell known in the foodindustry as well as inwood working industry.

Starting from a boardmaking industry morethan 30 years ago a tech-nology and system ai-ming at preventing thisrisk was developed.

– The way of thinkingof safety aspects and riskmanagement varies bet-ween different marketsand different countries,says Anders Bergström,market manager at Fireflyin Stockholm, Sweden.

Not many securitysystems can handle the

heavy streams of bio-mass material before alarge boiler in a heat andpower plant or in a pel-let plant.

The system has to de-tect a potentially dan-gerous hot particle andcool it down before atdevelops to a fire or ex-plosion and at thesame time doing thiswithout interrupting theprocess.

Risk analysis– To do this we usuallystart with a risk analysisof the process, says An-ders Bergström. In this wecan identify the sources ofdangerous particles, e.g.machines as mills, pelletpresses that can generateignition sources.

The effect is often notseen in these machinesbut in a risk zone with amixture of dust and airthat is explosive.

In the risk analysis we

study drawings and lookat the process to be ableto design a system thatdetects the ignition sour-ce, cool it or divert itfrom the risk zone via avalve.

High speeddetection

The essential part of thesolution is a sensor withinfrared cells which de-tect if something with acertain temperature andmass is passing by athigh speed. In pneuma-tic transport ducts thespeed of the material canreach 30 meter per se-cond and in a matter of

milliseconds the detectorhas to react and identifyif the particle isdangerous.

Another importantaspect is that the sensorsshould not give unneces-sary false alarms. Byusing a detector that isinsensitive to daylightthis risk can be kept to aminimum.

Efficient extinguis-hing

Downstream the detec-tor there is an extinguis-hing zone, e.g. Divertingvale, isolation valve,CO2 extinguishing.

In most cases water is

injected during 2 se-conds. After this the hotparticle is cooled downand the process continu-es without interruption.

Many biomass fuel-handling systems todayare handling very heavymaterial flows. This putsextra demand to the wa-ter extinguishing system.

A high water pressure7-9 bar and full-conenozzles gives large waterdroplets and a high mo-mentum of the ext-inguishing water. This incombination with the lo-cation of the nozzles, thatmust be located from dif-ferent directions into thechute, is the key for suc-cessful extinguishing.

The new heat plant inSolna, Sweden is a goodexample of how the sys-tem can be implemen-ted. Bioenergy Interna-tional will come back tothis in a near future.

14 ->God for biogas

If these plans are reali-sed, it’s expected, thatthere will mainly bemore power producedin small biogas plants.

The use of naturalwood however won’tbenefit much. As aconsequence, thetechnic of biogasplants could ”mature”by mass production.So the biogas sectorcould benefit interna-tionally by this law.

There is still an ex-pected half of a year,until the law will passthe German parlia-ment with a majoritybuilt by Labour andthe green party.

Right now there aremany discussions,whether the condi-tions for power frombiomass should beeven more improved.

The prospects foreven better conditionsare good.

This is due to thefact, that the farmers,who can deliver thefuel for the biogasplants, traditionallyvote mainly conserva-tive.

The main obstaclefor these improve-ments could howeverbe the fears of the in-dustry of higher powerprices.

The main argumentof the secretary for theenvironment from thegreen party, JürgenTrittin, against thesefears is the expecta-tion, that the prices forpower from renewableenergies could fall wit-hin ten years to a eco-nomically appropriatelevel.

This expectation isfueled by the hope ofa ”technical revolu-tion” induced by thelaw.

supply wood of anykind and quality fromintact stems to woodchips. All species of treesare suitable for woodchips production forwhich mobile as well asstationary chippers arein operation.

Container trucks car-ry the fuel to the co-ge-neration plant.

It is possible to usewood with a water con-tent between 15 and 55per cent. So seasonalfluctuations of watercontent of the used bio-mass will not cause pro-blems.

Ashes recirculatesThe use of the ashes ari-sing from the firing pro-cess is circulated back toagriculture sector whereit is used as fertilizer.

This is not yet in linewith the German Fertili-zer Ordinance from1999 or with the Bio-mass Ordinance from2001, but with theamendment to the Ferti-lizer Ordinance havingpassed Parliament andbeing now in Federal

the biomass co-ge-

CombustionsWood chips are burnedin a special biomass boi-ler on a water-cooled vi-bration grate. The max-imum heating power is26.7 MW.

Heat & PowerFrom oil to biomass:

Only wood from theregion was to be used asa sustainable energysource.

At that time oil pricesin Germany were notvery high (16 ct/l HEL),whereas biomass (at thattime only wood wastewas in use) was regardedas not economic.

This required a usableand cost-efficient fuel lo-gistics and also a soundsale structure. So eta-en-ergieberatug elaborateda draft concept whichforesaw:

• evaluation of the lo-cation (infrastructure,distance to costumers),

• estimation of theheat demand and actualprices,

• dimensioning of im-portant system compo-nents (boiler, turbine),

• estimate of wooddemand and prices forwood chips,

• calculation of pro-

fitability and financingconcepts.

Furthermore therewas a very detailed con-cept needed in manyothe areas which is pre-sented in fig 3 above.

Finding acceptanceof the plant with

inhabitantsFirst of all some bigcustomers of energy likeHipp, the Ilmtal Hospi-tal and a few other en-terprises, as well as com-mune and district admi-nistration of Pfaffenho-fen could be won forlong-term contracts tobuy energy from the co-generation plant at thesame price as they wereused to buy oil or gas.

A little later the enter-prise Müller-Bräu, a bigbrewery, signed a cont-ract to buy coolingwhich they need duringsummer time.

Rather difficult tur-

ned out to be winningprivate customers forheat and power. Up tothis time in Pfaffenhofenno district heating netexisted, and people wererather sceptical.

Strong reservationsexisted particularlyagainst possible emis-sions like air pollutantsand noise, as well asagainst a sustainablefuel supply through na-tural wood. The opposi-tion of a group of inha-bitants of the townagainst the plant had tobe taken seriously.

So the planners andconstructors engagedthemselves in convincingpeople of the economi-cal and comfort benefitsof using heat, power andchill supplied by the bio-mass plant, and withpermanent informationin town meetings, semi-nars, promotion standson street corners they

succeeded in winning aconsiderable number ofcitizens to support theerection of the plant andto agree buying heat andpower from it.

ReferendumTwo citizen initiativesformed themselves: onewas pro plant, the othercontra.

In the end the suppor-ting votes had the major-ity in a referendum.

Finally the biomassplant could be erected inthe years 2000 and 2001and parallel to it the di-strict heating net wasbuilt.

In July 2001 the plantwas put into operationin a formal ceremonywith a speech of the Par-liamentary Secretary ofState, Mrs. Probst.

In the meantime thebiomass plant has foundan increasing acceptanceamong the populationof Pfaffenhofen. Somore and more privateconsumers show theirinterest in getting con-nected to the districtheating.

Know-how transferto prospective

project developersWith new developmentsin German energy andenvironmental policy,i.a. the Renewable Ener-gy Act from April 1,2000 which grants att-ractive feed-in tariffs forenergy from renewable

sources, an increasinginterest in building andrunning biomass plantsis to be seen.

In the Pfaffenhofenplant a technique wasused which was availa-ble on the market andcould be combined witha detailed concept tocope with the special de-mands of location, fuelsupply possibilities, con-sumer structure etc.

Its practical applicabi-lity could be proved to-gether with a solid eco-nomic operation and en-vironmentally effectiveresults. These experienc-es can be taken over inother planned installa-tions. So particularlyparts of the project likefuel logistics, fuel hand-ling and use of ashes areof great interest for allprofessionals dealingwith that matter likeuniversities, expertsfrom regional and localadministrations andfrom enterprises fromGermany as well asfrom other countries. Somany lectures concer-ning the technique of theplant, thermal produc-tion of chill and econo-my of operating such aplant have been held onnational and internatio-nal conferences. A consi-derable number of poli-ticians, experts, interes-ted persons and groupshave visited the Pfaffen-hofen plant.

4. ConclusionBiomass plants for pro-ducing energy for power,heat and chill are econo-mical!

This statement is valideven without taking intoaccount the comparablyhigh German feed-in ta-riffs for renewables.

But planning, buildingand operating plants ofthis kind are more com-plex and more difficultthan those run with oth-er renewable energies.

Efficient fuel logisticsand fuel supply, sale ofpower and heat duringthe whole year withmaximal output as wellas finding the optimaland reliable techniquehave to be carefullyplanned and harmoni-zed especially in regardto specific local condi-tions.

This makes coopera-tion of experts from dif-ferent disciplines neces-sary.

Three main columnsare important for aneconomically soundrunning of the plant:

1. efficient fuel supp-ly,

2. a technique adjus-ted to the demand and

3. long-term securedenergy sale.

The Pfaffenhofen bio-mass co-generationplant as a pilot projectwas supported with agovernment grant fromthe ”Investment Pro-gram for Reduction ofEnvironmental Loads”by the Federal Ministryfor the Environment,Nature Conservationand Nuclear Safety andwith an investmentgrant by the BavarianState Ministry for Agri-culture and Forestry.

But with an appropri-ate concept biomassplants are nowadayssuccessful even withoutany financial support.

For pellet stoves:

Telephone activatedcontrol system

Rika’s Premio - presented with the newcontrol system at the International

Trade Fair ISH Frankfurt.

Control via mobilephone or fixed net-work helps save upto 25-30% of pri-mary heating costs.

The new control sys-tem is supplied by

the Austrian manufactu-rer Rika.

The novelty is that thepellet stove is able to beactivated by an externalcall.

This new kind of flex-ibility allows you e.g. tokeep all rooms at a cons-tant temperature of 15°C via your primary hea-ting source, and create

the individually desiredcosy warmth with yourpellets stove at preciselythe required time.

Just by lowering yourprimary heat source byone degree you will savearound 5 per cent onfuel costs.

This specific kind ofcontrol system meetsone of the most essenti-al current customerneeds for independencyand flexibility, thusproviding an excellentbusiness opportunity forthe specialised trade.

In the new develop-ment, special attention

was paid to serviceabil-ity, user friendliness andoperational safety, alsoto a broad ability rangewith a high efficiency le-vel in all capacity rang-es from 2-8kW.

The control system isavailable in all Rika pel-let stoves.

New system forsmall scale sto-rage of pellets

The new storage sys-tem for wood-pelletswith integrated with-drawal (delivery-sys-tem) for boilers forfamily-houses is cal-led Geobox. It is developed byGeoplast, an austriancompany, which isspecialised in produ-cing tanks for stora-ge. The Geobox issupplied in seperateparts, which makes itvery easy to assem-ble in most rooms.

By the variable con-tainer height the boxadapts individually tothe room height, andthus a maximumspace utilization.

The Geobox can beset up also in the up-per floor or effectedat the attic, the with–drawal by means offall-pipe or suctionsystem.

A further possibility isthe location outsidethe house.

It is possible to sto-re in the Geobox bet-ween 3.2 and 6.7tonnes pellets.

In Solna, in the cen-tral great Stockholmarea a large oil fired

heating plant is conver-ted to biomass. Two 50MW boilers will use pul-verised dry biomassfrom the start of 2004.

The investment is esti-mated to 22 millionEuro. Taking into ac-count the heavy taxationon fossil fuels used forheating, 3-4 million Eurowill be saved annually.

No land availableThe plant, located inSolna by the sea, is sur-rounded by water onone side, a major roadon one side and officeson another side. A fewhundred meters awayare a number of multi-family houses. The sur-roundings are denselypopulated and there wasno land available forbuilding a biomass plantfuelled with wet bio-mass.

– The message fromour leading politicianswas that we must use thesite we already have,says Sven Jonsson, pro-duct manager at Norr-energi, supplying Solnaand Sundbyberg withheat and power. Whenthis finally was clear tous, the decision was ea-sier to make. Dry bio-mass was our choise,says Sven Jonsson.

Fuel by train, shipand trucks

The yearly supplyneeded is approximately60 000 tons. This will betransported by trainfrom HMAB innorthern part of Swedenand by boat from SBE toa terminal for reloading.Trucks will feed theplant from a close bystorage site. Mebio willalso supply smaller volu-mes. The Saxlund hand-ling equipment will feedthe two Champion mills

with briquettes and pel-lets. The powder will beburned in four burnersfrom VTS with a capaci-ty of 20 MW each.

What’s up with the weather, natural variation or greenhouse

gas, is for meteorologists to debate. Yet, the growing consen-

sus amongst global leaders is the effect of global warming is

fact and that it’s time to go for renewable energy sources, big

time.

Many countries have, by ratifying the Kyoto agreement, obliged themselves to

decreasing their emission levels of carbon dioxide. The deadlines for

meeting these obligations is running out.

This is the background for the World Bioenergy 2004 international conference

and tradeshow to be held in Jönköping, Sweden. This international event is

expected to attract more participants than any other comparable conference. For

the first time the tradeshow itself is of paramount importance. It is no longer

enough to discuss the challenges and possibilities facing bioenergy solutions

tomorrow, it is time to invest in the leading

technologies available today.

Make sure that your company is part of the

picture when buyers of bioenergy technology

and solutions arrive in Jönköping next June.
