very small part of the micro-algae. As seawater is used, no indirect
energy consumption is considered for water supply, similar to
[44,19]. Power consumption for seawater pumps is considered as
well as direct power consumption from paddle wheels. Energy
consumption of monitoring and CO2 and nutrient inlet equipment
is not taken into account. Local power production efficiencies are
considered when determining indirect energy consumption from
power consumption. However, electricity consumption of paddle
wheels and harvesting pumps is relatively low, resulting in a small
contribution to direct energy consumption ratio, 0.06, 0.07 and
