Overall objectives To develop the basis for a sustainable, cost-effective bioenergy industry in Norway in order to double the bioenergy use by 2020 ► CenBio focus on stationary bioenergy (Heat and Power) ► Action 1. Production of and accessibility to biomass for energy purposes will have to be increased substantially. ► Action 2. Great improvements must be made in the efficiency of biomass production, energy conversion and applications of bioenergy. ► Requirement 1. By-products need to be upgraded in order to be ecologically recycled. ► Requirement 2. Sustainability must be documented for complete bioenergy value chains to enable sustainable and cost-efficient bioenergy 2009-09-29

Feedstock supply Tasks Assess forest biomass availability Quantify biomass fractions (stem, top, branches) Develop silvicultural methods to increase production

Logistics Task Develop effective logistic chains that include harvesting, processing, storage and transport 2009-09-29

Biomass quality Tasks Analyse the impact of variations of moisture, energy content, ash content and density on practical fuel quality Determine the links between fuel quality, conversion efficiency and costs

Biogas production The challenge: Biogas reactors produce substantially less methane (CH4) than what is the energy content of the biomass input Actions: Increase the efficiency of the conversion process by 1. Mixing biomass from different sources 2. Pre treatment of the biomass input

Sustainability WHAT. Based on three pillars: environmental, social and economic factors. WHY. The bioenergy industry has to rely on documented sustainability HOW. Life Cycle Assessments will be used as a tool for calculating sustainability, and as input to scenario studies of bioenergy systems The costs of bioenergy alternatives will be quantified We will analyse the competition for forest fibre used for bioenergy, paper and construction materials purposes, and the resulting fibre prices. Ecosystem studies will document the effect of harvesting branches and tops on soil, fungi, vegetation and biodiversity 2009-09-29
