“…Kumar et al [15] also investigated the pipeline hydro-transport of corn stover and found the one-way pipeline at a scale of 1.0e2.0 M t y À1 dry corn stover and mixture solid volume content of above 15% to cost less than truck delivery (Fig. 7).…”

“…Drawing on the works of Wasp et al [28] on pipelining wood chips and Liu et al [56] on pipelining compressed coal cylinders, Kumar et al [15] developed pipeline cost estimates for transporting wood chip-water mixtures; these estimates are shown on Table 3 and Fig. 7(a).…”

“…Nardi [34] suggested a similar technique for wood chips to inject the chemicals into a heated section near the receiving facility. Kumar et al [15] examined the simultaneous saccharification and transport (SST) on a corn stover hydro-transport pipeline. It was found that, since the current cellulase enzyme (that converts starch into sugar) causes an acidic environment in the pipe, the SST requires a prohibitively expensive stainless steel pipeline that makes it technically and economically inapplicable.…”

“…Costs for truck transport to the pipeline inlet are identical to those for rail transport. Pipeline costs are derived from a previous study (7). Note that pipeline costs show a significant economy of scale, whereas truck and rail transport do not.…”

Logistics cost, the cost of moving feedstock or products, is a key component of the overall cost of recovering energy from biomass. In this study, we calculate for small- and large-project sizes, the relative cost of transportation by truck, rail, ship, and pipeline for three biomass feedstocks, by truck and pipeline for ethanol, and by transmission line for electrical power. Distance fixed costs (loading and unloading) and distance variable costs (transport, including power losses during transmission), are calculated for each biomass type and mode of transportation. Costs are normalized to a common basis of a giga Joules of biomass. The relative cost of moving products vs feedstock is an approximate measure of the incentive for location of biomass processing at the source of biomass, rather than at the point of ultimate consumption of produced energy. In general, the cost of transporting biomass is more than the cost of transporting its energy products. The gap in cost for transporting biomass vs power is significantly higher than the incremental cost of building and operating a power plant remote from a transmission grid. The cost of power transmission and ethanol transport by pipeline is highly dependent on scale of project. Transport of ethanol by truck has a lower cost than by pipeline up to capacities of 1800 t/d. The high cost of transshipment to a ship precludes shipping from being an economical mode of transport for distances less than 800 km (woodchips) and 1500 km (baled agricultural residues).

“…Upstream equipment includes receiving, slurry making, and initial pumping. The elements along the pipeline are the booster pumps and, at the end, the equipment for draining the biomass from the carrier liquid (Kumar et al 2005 ). Unlike truck and train transport, there is an economy of scale for pipeline transport.…”
