Comparison of Microalgal Oil and Diesel


Rough excavation cost

Rough Excavation Cost

  • Need approx 25,000 of 980.0 square meters of 0.30 meter deep trenches for raceway ponds. Is approx 10,337 cf of “dirt” removed for each pond.

  • Excavation includes machine excavation with front end loader or backhoe, two trucks with 30 minute trips per load. Dumping fee not included.

  • Have not taken into account any tree or rubble removal from site or any concrete laying etc. Only dirt dig and removal.


Rough excavation cost1

Rough Excavation Cost

  • May be able to sell dirt from dig.

  • Labor cost is $1,156

  • Cost of removal of cf of “dirt” is $7,649

  • Total is $8,805 (per pond) X 25,000 ponds = $220,125,000

  • Estimated from online calculator “HomeTech Cost Estimator”


Plant cost

Plant Cost

  • Algae Production

    • $220,000,000

    • Does not include cost of PBR tanks and FDSF

  • Extraction

    • $24,000,000

    • Scaled from soy crush plant estimates

  • Biodiesel Production

    • $183,564,777

    • Scaled from DOE data
