The net energy ratio (NER) for each process was calculated. The results showed that the use of horizontal tubular photobioreactors (PBRs) is not economically feasible ([NER] < 1) and that the estimated NERs for flat-plate PBRs and raceway ponds is >1. The NER for ponds and flat-plate PBRs could be raised to significantly higher values if the lipid content of the biomass were increased to 60% dw/cwd. Although neither system is currently competitive with petroleum, the threshold oil cost at which this would occur was also estimated.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-05-30T20:58:19Z No. of bitstreams: 1 (44)1-s2.0-S0960852409012449-main.pdf: 667025 bytes, checksum: 9776e009028439bec92bea1d5e2fb81c (MD5)Made available in DSpace on 2012-05-30T20:58:19Z (GMT).
