Before a biogas plant is built or a biogas program is implemented, a techno-economic assessment should be made. For this, two sets of cost-benefit analyses have to be carried out:
· The macro-economic analysis (economic analysis) which compares the costs of a biogas program and the benefits for the country or the society.
· The micro-economic analysis (financial analysis) which judges the profitability of a biogas unit from the point of view of the user.
Even if today the technical performance of biogas plants no longer constitutes a problem, and even if regions favourable for biogas can be relatively easily identified, the establishing of an efficient and sustainable dissemination structure continues to remain the key problem of numerous biogas projects. In various countries, experiences with the dissemination of agricultural biogas systems exist. Depending on the stage of biogas development in a country or region, the structure of a biogas programme reflects the phases of implementation:
· Research and development
· Pilot programs
