Instead, they appear to favour drop-in fuels made from bio-based hydrocarbons, which properties are similar to those of standard petrol and diesel and can be produced in existing oil refineries. Such advanced drop-ins are being made on a pilot scale by Bio4Energy member RISE Energy Technology Center at Piteå, Sweden and their partner Suncarbon. So-called de-polymerisation of the wood polymer lignin could be a basis for this type of process.
The report, ending a project called BeWhere - Stakeholder analysis of biofuel production in Sweden, is based on an international energy system model called BeWhere, but which has been adapted to national conditions.
The results, published last month, caps off a system analysis project kicked off in 2012 to identify the most advantageous locations for biofuel production in Sweden, financed by the Swedish Knowledge Centre for Renewable Transportation Fuels (f3 Centre) and the Swedish Energy Agency via a national research programme named Renewable Fuels and Systems.
The results of the model runs, complemented with analysis of stakeholder workshops and interviews, are designed to guide policy-makers in their efforts to determine which type of biofuel technology to support. Cost-efficiency has been a key criterion for gauging the optimal type, size and location of possible biofuel production facilities.
More specifically, the package is "part of a larger toolbox in the transformation towards large-scale forest-based biofuel production. The model is intended to be used at a strategic decision-making level. This type of decision-making refers to long-term decisions that usually involve investment-intensive decisions, and which typically pertain to the design of the biomass supply network and policies affecting this", according to the report.
