Drying Energy Cost at 110% included drying cost share: a worked example

What does the result look like when included drying cost share reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when drying or moisture-control energy needs to be included in a production quote, pilot trial, cost standard, or process comparison.

The inputs for this scenario

  • Dried anode material mass: 1,200 kg (unchanged)
  • Drying energy cost per kg: 0.42 $ / kg (unchanged)
  • Included drying cost share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed dryer setup cost: 350 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable drying energy cost = dried anode material mass × drying energy cost per kg × included drying cost share) to the inputs above produces each figure below.
  • At this operating point the engine returns 904 $ for total drying energy cost, the number this scenario is built around.
  • At this operating point the engine returns 0.75 $ / piece for drying energy cost per kg processed.
  • At this operating point the engine returns 554 $ for variable drying energy cost.
  • At this operating point the engine returns 350 $ for fixed dryer setup cost.

How this compares with the baseline

  • Against the tool's baseline example, where included drying cost share sits at 100% and the headline result is 854 $, this scenario comes in 5.9% above the baseline at 904 $.
  • A figure at this level is achievable when included drying cost share is genuinely sustained, not just peaked for a shift. It treats energy cost per kg as flat, but real specific energy rises sharply for high-moisture or solvent-laden feeds, so a single rate can understate cost for wet material.
