Hvorfor ikke brænde biomassen af?- mest

CO2 og mest netto energi Hvorfor ikke brænde biomassen af?- mest

CO2 og mest netto energi Fordi biomasse kan bruges til at løse

olieafhængigheden i transportsektoren Fordi biobrændstofproduktion går hånd i hånd med

forbrænding Fordi der ikke altid er brug for overskudsvarme Fordi der er forskel på energikvaliteter Fordi forbrænding er dyrt (tilskud på imellem 500 og

800 kr pr. ton halm) Fordi det ikke er en global løsning
