Taloudellisesti kilpailukykyinen kokoluokka on erittäin suuri• Vähintään 100-200 ktoe/a tuotanto; biomassasyöttö 300-600 MW• Tarvittava investointi 500 -1000 M€• Ensimmäinen laitos jopa 50 % kalliimpi kuin kypsä teknologia• Tekniset ja taloudelliset riskit liian suuret – julkisen tuen tarve liian suuri• Sivutuotelämpöä syntyy 100-200 MW – usein vaan lahdevoimaksi
Raaka-aineen hankinta ja logistiikka haasteellista• Paikallisesti saatavilla olevien tähteiden määrä rajallinen• Laitos joutuu käyttämään myös runkopuuta/kuitupuuta• Raaka-ainekustannukset nousevat helposti tasolle 25-30 €/MWh
Tarvitaan hajautettua pienemmän kokoluokan teknologiaa!• Prosessin yksinkertaistaminen ja CAPEXIN alentaminen• Integroinnin maksimointi: biomassalogistiiikka, voimalaitosintegraatio• Paikallisten tähteiden ja jätteiden hyödyntäminen
Suuren kokoluokan keskitetyn kaasutus- ja synteesilaitoksen haasteet

Mikä rooli kaasutus-BTL-teknologialla energiamurroksessa 2030 jälkeen? Aurinko, tuuli ja maalämpö kasvavat voimakkaasti Hiilen käyttö vähenee voimakkaasti / loppuu kokonaan Perinteisen CHP-voimalaitosteknologian rooli pienenee Kevyt liikenne sähköistyy – perustuen uusiutuvaan sähköön Maakaasu säilyttää asemansa hiiltä pidempään Myös teollisuuden prosessihöyryn tarve säilyy ja yhdyskuntien
lämmitystarve nykyistä pienempänä Raskas liikenne tarvitsee vähähiilistä polttoainetta ja kemian
teollisuus raaka-aineita
Kehitetään hajautettuun tuotantoon ja pienille lämpökuormille soveltuva prosessi joka pystyy mukautumaan vaihtelevasti saatavilla olevaan aurinko- ja tuulienergiaan

SXB – PILOT AT BIORUUKKI, 2016
“Biomass will have a significant role also in the future renewable energy mix, but the use will be partly shifted from the present heat and power
production to the production of fuels and chemicals – on this road gasification
technologies will play a key role”
