Abstract
A system and method are provided for growing microalgae in cold climate areas. The system includes an expanding Plug Flow Reactor with a plurality of ponds used to grow algae by mixing a culture fluid with a nutrient. To minimize the loss of heat due to environmental factors, the expanding Plug Flow Reactor is covered with a translucent, light-transmitting cover and is lined with an insulation liner. In addition, an underground sump and pump are provided and connected to the expanding Plug Flow Reactor. The sump is provided to store the algae at night when ambient air temperature is at its coldest. An adjacent power plant provides: (1) heat byproducts to warm the culture and (2) CO2 for use as a source of carbon in photosynthesis.
