Every major CO2 emitting industry needs an installation

Using algae to sequester CO2 from power plants and other CO2 emitting industries

Every major CO2 emitting industry needs an installation

Postby cacofonix » Thu Jan 29, 2009 6:37 am

Every major industry that generates CO2 or other organic gas emissions needs its friendly algae installation. So feels Riggs Eckelberry, CEO of Origin Oil...see this post

Guess everyone is agreed on this in principle...as always, the question is the economics...from what I read, power plants that are going ahead with pilots for algae sequestration are finding that the cost economics are not clear. At least I have not heard a single power plant say clearly that they have their cost and business plan ready.

But sequestering CO2 geologically is an expensive (make that terribly expensive) process as well...so when one does all the pluses and minuses, there is a good chance algae sequestration could indeed prove very cost effective

If anyone has an idea of CO2 sequestration cost economics modelling for power plants, would most appreciate if they could provide me a reference, thanks!

The flue gas from power plants contains the so2 along with co2. Will it affect algal growth?

Sulfur oxides can have a significant effect on the growth rates of the microalgae. It’ll reduce the pH of the growth medium which significantly affects the productivity of the microalgae. However, we can maintain the pH at 8 using NaOH.

Hai,
The exact mechanism is that the sulfur oxides dissolves in medium forming sulphuric acid which reduces the pH.. which can be adjusted by adding sodium hydroxide. This is a form of neutralization which gives sodium sulphate and water. And now what happens to this sodium sulphate ? Will algae use it as nutrient?
