Cultivation-system-related parameters (own estimates based on/completed with [9, 25, 26]).

	Raceway ponds	Closed systems
Photoconversion efficiency	1.5	5	%
Typical biomass concentration	0.5 to 1	2 to 9	kg/m³
Spec. energy demand cultivation (per area)	0.5 to 4	2.5 to 15*	W/m²

^∗Based on the volumetric demand of 50 to 150 W/m³ for closed systems and a volume/surface ratio from 0.05 to 0.1 m³/m² [23, 27].
