The technical and economic feasibility and environmental performance of atmospheric gasification for electricity production of biomass wastes and residues is investigated for Dutch conditions. The potential of biomass wastes and residues in The Netherlands amounts over 100 PJ/yr. Characteristics, supply during the year, degree of contamination and (negative) costs differ widely per stream: between minus 10-6 ECU/GU (HHV) (**). An ACFB/CC system based on the General Electric LM 2500 gas turbine and TPS atmospheric gasification technology, including the flue gas drying and low temperature gas cleaning is selected. The system performance is assessed for clean wood, verge grass, organic domestic waste, demolition wood and a wood sludge mixture. Integral systems calculations are performed by using an ASPEN{sup +} model. Fuel gas compositions for various fuels were derived by lab scale gasification tests of various fuels and model calculations. The net calculated system efficiencies lies between 35.4-40.3% (LHV) for various fuels, with significant potential for further optimization. Estimated investment costs based on suppliers information amount 1500-2400 ECU/kW-installed, the upper range representing a first plant, the lower the cost level on longer term. Electricity production costs, including logistics and (negative) fuel price vary between minus 6.7-8.5 ECU ct/kWh, the negative values caused by present waste treatment being a source of income to the conversion facility. Environmental performance is expected to meet the worlds` most stringent standards on waste incineration and the system seems flexible enough to process a wide variety of fuels. The economic analysis showed a high sensitivity of the kWh costs for the system efficiency but very most sensitivity for transport distance which pleads for application of larger scale plants. As a waste treatment option this concept seems to beat all alternatives presently applied.
