Description
Summary:This paper presents our endeavor to establish a feasible renewable energy power plant in Bangladesh. Our primary energy source is the municipal waste in Dhaka city. The organic compounds present in waste produces biomethane by anaerobic digestion. But the combustion of this gas emits harmful CO 2 . To reduce emissions substantially, an algae pond is proposed where the exhaust carbon dioxide is sequestered yielding algae growth. But algae appears to be a potential producer of biodiesel and biomethane; so it secondary source of renewable energy for our power production. The generator used for producing electricity works on the principle of magneto hydrodynamics (MHD). Input to our MHD generator is the thermal energy obtained from combustion of the renewable biomethane & biodiesel. Though the installation cost is high, we can benefit from the significant reduction of fuel cost & revenue earned from selling fertilizer. Our studies show that with the MHD generator working at 60% thermal efficiency, 90.6MW power can be produced for 24 hours.
