Photobioreactor panel energy indicators

Value

Biomethane production

612 m3 methane/year

Net energy as methane

Approx. 4,541 kWh/year.

Net energy from heat

Approx. 6,000 kWh/year

Carbon dioxide emission reduction

6 tons/year

Basic data per m2 bioreactor area biomass production

900 kg/year

Energy production from biomass

345 kj/m2/day

Approx. 4500 kW/h of electricity

  1. Note: Indicators for a 200-m2 bioreactor area with 300 days of production/year
  2. These values are considered minimum because of the more hours of sunshine in Giza than in Hamburg
