The Variety of Liquid Bio Fuels

Liquid Bio Fuels

A great varation of bio fuels canbe found

Approved by Wrtsil are: Vegetable based bio fuels:

Palm oil, Palm stearin, Rapeseed oil, etc.

Transesterified bio oils(biodiesel)

Animal based not approved DME (Di-Methyl Ether) not

approved Methanol & Ethanol not approved Bio oil alcohol mixes not

approved

Lower Heating value => Outputreduction

Sources of Liquid Bio Fuels

Sources of vegetable oils (2003) Palm oil (28.3M tons/year)

Malaysia (47%) Indonesia (37%)

Soy Bean (31M tons) USA Sourth Europe

Rapeseed (12.3M tons) North Europe

Sunflower (8.6M tons) South Europe

Total Oils&Fat production

2003: 123.5 million tonnes Animal fats 23M tons

28.3 Mtons is enough for 14000MW continous

Prices of Liquid Bio Fuels

Price development Palm oil price development

has been positive over longterm trend With HFO at 250 300 $/ton

and Palm oil at 400$/ton, thepower generation market

requires subsidies to becomecommercially attractive CO2 trading and incentives in

Italy, Holland and Germanyhave created local markets

for LBF power plants 0

Varying characteristics Ash content

Clear oil & dark oils havedifferent level of ash

Influence on particulateemissions

Viscosity is highlytemperature dependant

Too cold -> wax Too hot -> polymerization

MW in operation

MW development The introduction of incentives

in Italy has created a fastgrowing installed base of LBFplants

Projected estimates suggestthat up to 500MW of LBF

plants could be in operationby end of this decade

LBF business models

Four models Crudel Vegetable Oils

The primary model for using

LBF. Bio diesel

Today very expensive, notreally feasible for powergeneration

Waste oils from food industry

Karlburg plant model, but waslater changed to by products.Problem: Emissions

Waste or fuel? Which EUdirectives are to be used?

By-products

Main customers are companiesoperating in Bio-oil refinerybusiness
