NYKOMB SYNERGETICS 7. Methanol Production Cost For the production of 1,000 tonnes/day of fuel-grade methanol the calculated production cost per year is US $0.28/litre or ECU 0.25/litre. This has been calculated with a typical feedstock cost of ECU 9.5/MWh and 12 % annuity. Furthermore, in the calculated cost there has been no credit taken for the available production of heat for distant heating. Exchange rates (PostGirot, 26 September 1997): 1 USD = 7.50 SEK 1 DEM = 4.29 SEK 1 ECU = 8.50 (set rate by Authors). 8. Commercial Demonstration Ecotraffic R&D AB For the commercial demonstration, the subsequent phase of efforts will clearly focus on selecting a raw materials base, a site, a process configuration, product slate, and a commercial investor partnership and alliances which will meet the following criteria: • Robust investment object in terms of product flexibility. • Sustainable long term operation. • Plant scale minimum to meet commercial demonstration objective. • Transport fuel produced which will be compatible with major automotive actors’ long range views. • Overall economics to provide a commercial return after allowing for compensation for small scale and short term market aberrations in pricing of competing fossil-based fuels. • Possibility to organise a substantial fleet demonstration for the biomass derived fuel. An overriding consideration is that the selection of project specifications shall be made in such a way that a successful commercial demonstration is as far as possible assured - i.e., a commercial return on the partnership’s risk capital shall be likely in view of the parameters at hand.

NYKOMB SYNERGETICS 9. Logistics and Site Location Ecotraffic R&D AB Even for a fairly modest demonstration plant, the logistic task of securing biomass feedstock is a significant one. The ideal candidate sites for a methanol production plant are sites where substantial volumes of forestry material is at hand or can be transported at low costs, i.e., in conjunction with pulp mills, preferably with integrated sawmills. At such sites the logistic investment is largely in place and cross haul costs would be minimised on the way from the logging/harvesting operation to the plant. Also, the ideal site should provide a possibility of heat and utility integration with the commercial demonstration site. Thus, on assignment of County Administrative Boards of Jämtland and of Västernorrland and for Trollhättan Municipality site studies have been made. Furthermore, Växjö Energi AB has indicated interest to locate a methanol production plant. Man power needed for operation of the plant is estimated to 60 - 70 people and an estimated 8 trucks/hr will be needed for transport of the raw material, provided that the plant is not to be located at a site where primary fuel is already in place. The 1,000 tonnes/day or 1250 m 3 /day produced methanol will have a purity of 99.85 % and will be stored in two 5000 m 3 cisterns. These will be alternatively used for production, storage and loading. Coastal tankers and/or tank trucks with a maximum carrying volume of 53 m 3 of fuel will transport the methanol to central tank farm storage facilities for longtime storage. An estimated 2 trucks/hr will be needed for transport of the fuel. At the tank farm, fuels to be marketed (excluding methanol only fuel, which require no further upgrading and thus can be sold direct) will be produced by blending with diesel and/or gasoline. The fuel products will further be sold via the present commercial distribution line of tank trucks and gas stations. 10. Engine Testing Engine testing for a 11 litre heavy duty diesel engine with 12 vol. % methanol (water-free) emulsified in diesel oil showed in comparison with pure diesel oil a considerable reduction of emissions of nitrogen oxides (NOx) and particles. However, a slight reduction (4 - 5 %) of power and torque was noted, but with an improved efficiency (2 - 3 %). Parallel tests with 15 vol. % ethanol (azeotrope) emulsified in diesel oil did not produce the reduction of NOx emissions recorded for methanol, and earlier tests elsewhere could not be reproduced. In conclusion, alcohol-only fuels are effective in reducing emissions of NOx, particles and poly-cyclic aromatic hydrocarbons (PAHs) and their biological effects. In these respects, tests also show that the environmentally classified oils in Sweden (very low contents of PAHs and sulphur) are superior to European standard diesel oils.
