“…According to Dornburg and Faaij [47] the influences of logistics on the total costs increases with the scale of the plant, due to increasing the supplying areas therefore having higher transportation distances. Therefore, both the yield of biomass per unit area and the location of the biomass have an impact also when determining the optimum size of a power plant [48]. Follow up studies should compare the supply costs between the other two peat power stations in Ireland.…”

Highlights A linear programming model that optimises wood biomass supply in Ireland. It uses MC to determine harvesting, chipping, storage and transportation costs. It analyses two supply chain scenarios and two truck configurations. Low wood MC increases supply cost due to longer transport distances. Optimal truck loads can be achieved by controlling wood MC. AbstractIn the coming years, Ireland will continue to face an increasing demand for wood biomass as a renewable source of energy. This will result in strained supply/demand scenarios, which will call for new planning and logistics systems capable of optimizing the efficient use of the biomass resources.In this study, a linear programming tool was developed which includes moisture content (MC) as a driving factor for the cost optimisation of two supply chains that use short wood and whole trees from thinnings as material feedstock. The tool was designed and implemented to analyse the impact of moisture content and truck configurations (5-axle and 6-axle trucks) on supply chain costs and spatial distribution of the supply materials. The results indicate that the inclusion of wood chips from whole trees reduces the costs of wood energy supply in comparison with only producing wood chips from short wood to satisfy the demand, with 9.8% and 10.2% cost reduction when transported with 5-axle and 6-axle trucks, respectively. Constraining the MC of the wood chips delivered to the power plant increases both transport and overall supply chain costs, due, firstly to an increase in the haulage distance and secondly, to the number of counties providing the biomass material. In terms of truck configuration, the use of 6-axle trucks resulted in a 14.8% reduction in the number of truckloads and a 12.3% reduction in haulage costs in comparison to the use of 5-axle trucks across the MC scenarios analysed.

“…Bigger plants demand more material and results in bigger supply areas which in turn increases transport distances and costs (Dornburg & Faaij 2001). Also, both the yield of biomass per unit area and the location of the biomass have an impact on the optimum size and location of the power plants (Kumar et al 2003).…”

“…This gives a surplus of 2.2 million tons straw/year or 40 % of the total production [1]. The straw-to-grain ratio is assumed to be 1.1:1 on the basis of its mass fraction [22]. Accordingly, a portion of the impact from common operations for straw and grain (from cultivation to harvesting) is allocated to straw.…”

The conversion of biomass to four different outputs via gasification is a renewable technology that could reduce the use of fossil fuels and greenhouse gas (GHG) emissions. This study investigates the energy aspects for a new concept of biomass based quad-generation plant producing power, heat, methanol and methane. Circulating fluidized bed gasifier and the gas technology institute (GTI) gasifier technologies are used for this quad-generation process. Two different biomass feedstocks are considered in this study. The net energy ratio for six different pathways having the range of between 1.3 and 7.2. The lowest limit corresponds to the wood chips-based power, heat, methanol and methane production pathway using GTI technology. Since more efficient alternatives exist for the generation of heat and electricity from biomass, it is argued that syngas is best used for methanol production. The aim of this study was to evaluate the energy performance, reduce GHG and acid rain precursor emission, and use of biomass for different outputs based on demand. Finally, a sensitivity analysis and a comparative study ar conducted for expected technological improvements and factors that could increase the energy performance.
