BIOENERGY SYSTEMS
Traditional Biomass
• over-exploitation of natural resources, • low economic valorization of biomass, • low efficienct technologies
Modern biomass
• commercial• efficient technologies• environmentally sustainable
production and use
BIOMASS AS ENERGY RESOURCE
Abundant energy resource
• It can be stored• It can be transformed into energy by different technologies (mechanical,
thermochemical, biological)• It provides solid, liquid and gaseous biofuels to use for heating, power and
transport purposes
• It can not be found free.
• It requires a long chain of activities: planting, growing, harvesting and pretreatment (storage and drying) before it can be transformed into an energy carrier.
• Biofuels have an associated cost that has to be considered.
… not only depends on more efficient conversion technologies (combustion, co-firing, gasification, second generation liquid biofuels)
but
A broad range of research topics should be considered such as biomass availability and logistics.
