0.19 for Bissau, Huelva an Uppsala respectively. Table 2 presents
a data overview, including assumptions, references and energy
consumption ratios, of the data used in the mass and energy balance
of raceway ponds.
A breakdown of both direct and indirect consumption ratios for
raceway ponds is shown in Fig. 5, clearly depicting the influence of
carbon dioxide supply to the indirect energy consumption. The
indirect energy consumption ratio is mainly determined by the
cultivation inputs, which are related to productivity: carbon dioxide
uptake, its utilisation efficiency and energy consumption during
carbon capture determining more than half of the total
indirect energy consumption ratio of the cultivation step. Therefore,
the total indirect energy consumption ratio is roughly similar
for the three selected locations. Only the power production efficiencies
are different, which causes small differences between
the three locations. The power production efficiency is 49.7%,
44.7% and 40.5% for Uppsala, Huelva and Bissau respectively. Direct
and indirect energy consumption ratios are 0.06 and 0.74 for Bissau,
0.07 and 0.75 for Huelva, and 0.19 and 0.97 for Uppsala
respectively.
