Methane SIBC

Anaerobic Digester Sunflower Holcomb Power Plant Algae Reactor Electricity Methane Energy Products BiogasElectricity Flue Gas Water Ammonia Coal-based Power Plant Subsystem l Flue gas emissions from the power plant are stripped as they flow through the algae reactor creating algae oil and solids. l Ammonia from the anaerobic digester can be used for the SCR in power plant and excess methane can replace some demand for natural gas. l Excess water from algae reactor can be cleaned for electricity production.

SIBC

Algae Reactor Converts C02 emissions into renewable fuels l Microalgae is the most primitive plant form - typically one or two cells. l This simple structure allows algae to be very efficient at converting sunlight, CO 2, and nutrients into oil (for biodiesel) and starch (for ethanol). l The algae reactor is capable of utilizing the waste CO 2 and NOx in flue gas and the nutrients from livestock/processing waste to create valuable energy products. l Algae systems have been research for decades including work by the National Renewable Energy Laboratory. Production was found to be viable but most work was done when fuel prices were half of what they are today. l No large scale algae reactor is in operation today but significant investment has been made recently in conjunction with higher global energy costs.
