Combustion CO2 & Nutrient Recovery For Algae Growth
Capturing CO2 from combustion exhaust is one thing, trying to turn it back into a fuel is quite another.
Patented photobioreactor waste-to-energy operations are commendable efforts owned and maintained by algepower.com. This company grows oil-bearing algae for biofuel production as well as other products, and employs CO2 to encourage growth of the tiny aquatic plants.
To simplify algae respiration processes, suggested here is to introduce methane (CH4), combustion-derived CO2 with nutrients entrained for algae growth.
Fresh water algae evolve with obvious differences from salt water phytoplankton. One difference being a free exchange of fresh water CO2 (dissolved oxygen) with the atmosphere while it's not the case for salt water, where CO2 goes in and stays there.
Current research shows fresh water lakes are in fact becoming sources of atmospheric CO2 in the Northern latitudes.
Our studies indicate we can get CO2 to dissolve readily into fresh water where it becomes available for carbonate formation - if we introduce additional hydroxides.
If not, we simply keep the water covered.
Further, the addition of native chalk (CaCO3), prevalent from the late Cretaceous Period, to fresh water ponds and lakes, should have an obvious effect of fresh water CO2 retention. From an algae point of view this turn of events may be an advantage.
Native to cooler regions, home-grown algae types are a already acclimatized variety which may enable renewed biofuel sources as well as food production if the right nutrients were to become available.
Seeding small Northern glacial meltwaters may encourage algae reactions which would not normally occur - at least in the foreseeable future.
This method can be found in our 2013 US Patent 8,354,086 B2, claim 21.
All patent-pending systems reuse self-contained chemical and water solutions from reservoirs featuring conservative operation with carbonate production as a by-product. The carbonate may be mixed with selected aggregates to form bricks or cement as an added benefit.
A water source is a requirement. All systems demand supervision and maintenance.
All systems are available upon request.
Essentially, our structured filter designs transition order from the abandoned and disordered waste produced all around us.
However, carbonate is not an isolated system and the second law holds, predicting ordered systems (like Sun and Earth) evolve toward disorder and randomness.
The decreasing entropy of carbon in this case, should last longer than frozen CO2 in empty oil wells. Both storage concepts are only subsystems of the larger one above.
