Fig. 6. Towards sustainable operation for algae diesel production using ethyl algaeate. Carbon mass flows for ethyl algaeate production to match 50,000,000 gallons per year
petroleum diesel (based on the lower heating value, LHV) or about 0.1% of the annual diesel consumption in the US. All values are in 107 mol carbon day1 unless indicated
otherwise. Arrow widths are roughly proportional to carbon mass flows.
