Ancillary Options

4 SKIES proposes there be up to 1000 kW (1 MW) of PV solar panels installed on the rooftop of the two planned vertical farm buildings to supply additional power to the project.

It may also be worthwhile to integrate non-traditional, renewable, and clean energy systems, such as bird-friendly wind turbines, building integrated photovoltaics (BIPV) and even solar street lighting with integrated wind turbines to demonstrate how these small-scale systems can be easily integrated into a project like KAHNAWAKE. In this regard, the project could attract many visitors interested in seeing how innovative renewable energy technologies can be integrated with modern co-generation or tri-generation technologies, like TRI-GEN-ZERO™.

Algae to make biodiesel
Photovoltaic panels

Although organic waste from the vertical farm operations is considered biomass, another rapid growing organic organism is algae, which can absorb more CO2 than most plants and in a shorter time. In fact, one kilogram of microalgae can capture nearly 1.83 kg of CO2 and can yield up to a hundred times their yield weight per year than food crops. Some algae can even have two harvest seasons in one day. 

The most important product from algae is biodiesel and the biomass can be processed into healthy food, animal feed, biogas and fertilizer. The CO2 concentration in the flue gas from the power plant is about 10% to 20%, otherwise the CO2 concentration in the a™osphere is around 380 ppm.  In order to capture the CO2 from the flue gas, the microalgae species used in the capture process must grow efficiently under the condition of the high CO2 concentration.
