Chapter XVII - Algae Grown Next to Major CO2 Emitting Industries

This page provides details of the chapter XVII, from the Comprehensive Oilgae Report. You can purchase this chapter alone using the payment button provided below.


CO2 sequestration refers to the process of isolating and storing CO2 which is a greenhouse gas. The conventional CO2 sequestration processes are highly power intensive and as a result, expensive. In a country like the U.S., where coal is the major fuel for power production, costs involved in sequestering CO2 emissions will run into several billions.

Many scientists and environmentalists think that algal farming, when it aligned closely to nature, will give the most promising results in this context. This chapter deals with the algae- based CO2 abatement with its various challenges and the current research works in this area of study.

Key Takeaways from the chapter

  1. For power plants and other entities that are large scale emitters of CO2, sequestering CO2 using algae provides the opportunity of monetizing through carbon credits while at the same time producing biofuels.
  2. It is expected that in future, commercial profit from algae biomass production could offset overall operational costs for CO2 sequestration.
  3. In addition to CO2 sequestration, another potential strategy to offset operational costs is to develop multi-functional systems such as waste treatment in conjunction with algae cultivation at power plants.
  4. Some research programs suggest that CO2 recovery for algae growth from existing processes at ethanol and ammonia plants could be relatively lower in cost than from cement, refineries, or power plants
  5. Over a dozen companies worldwide have made significant investments into algae-based CO2 capture research.
  6. Key challenges involve the large land requirements, inefficiencies in the actual process of CO2 capture and high costs of cultivation if photobioreactors are used.
  7. While algae-based CO2 abatement inherently has excellent potential, it is not expected to become commercialized until 2015.
