Although the curves in Fig. 4 do display the characteristic ',' Ushape. ''The curves become relatively flat beyond a plant size of.Approximately 290 million L / year (5000 bbl / day). This flatness.Means that although vegetable oil transportation cost does counter -.Balance the economy of scale benefit transportation cost, is.Not as influential in overall HDRD production cost as it is for overall.Production cost of other biomass products. The economically optimal.Plant size in each case was 812 million L / year (14 000, bbl / day).And the minimum costs of production were: $1.09 / L (canola oil.Feedstock), $0.85 / L (Camelina, oil feedstock meal sold), and $1.37.L (Camelina, oil feedstock meal not sold). Since the cost curves.Are relatively flat beyond a plant size of 290 million L / year.(5000 bbl / day), the economically optimal size of HDRD production.Plant is really a range of plant sizes (290 - 1161 million L / year or,,5000 - 20 000, bbl / day), rather than a single plant size. As shown in.Table 2 Neste has, recently built two HDRD plants within this size.Range (929 million L / year, or 16, 000 bbl / day).Based on the curves in Fig. 4 it is, clear that the HDRD production.Cost in Alberta is lowest for HDRD produced from, camelina oilBut only if camelina meal can be sold. If camelina meal cannot be.Sold then it, is cheaper to produce HDRD from canola oil. The difference.In production cost for each case is almost entirely due to.The differences in feedstock costs because the other costs involved.In converting vegetable oil to HDRD are very similar in magnitude.In order to illustrate how the magnitude of each cost component.Changes with, plant size a breakdown of the production costs for.A 58 million L / year (1000 bbl / day) and a 290 million L / year.(5000 bbl / day) HDRD plant (canola oil feedstock) are shown in.Fig. 5.
