The figure shows an oxyfuel zero emission power plant, algae production and fish farming.

The awareness of the increase in green gas emissions has resulted in the development of new technologies with lower emission and technologies that can accommodate capture and sequestration of carbon dioxide. Lower power costs combined with improved plant efficiencies and zero atmospheric pollution used to be a dream.

The Marine Cluster has been developed through several years and has its origins in oxyfuel technology designed for zero emission gas power plants.

  • Can produce excellent fodder for fish farming
  • Can produce healthy fish food and important nutrients for humans
  • Can contribute to solving the plastic waste problem in the ocean
  • Can convert wood to liquid biofuel and protein
  • Has no emissions to air, earth or water

Oxy-Fuel and Algae

A key advantage of the Marine Cluster is the idea to combine oxyfuel energy production with CO2 capture, algae processing and fish farming.

Production of microalgae for extracting biofuels and other products is an emerging industry. Accelerated algae growth rate can be achieved by adding pure CO2. Furthermore, the algae production process releaces oxygen. Thus, it seems that the combination of oxyfuel power production and algae production is a perfect match. The oxygen from the algae production can be used in the oxyfuel process, and the collected CO2 can be used to speed up algae growth.

The algae production process requires significant nutrient supply for conituous algal growth. This supply can come from normal fertilizer products. Norway has however a large fish farming industry, where emissions of nutrients is a large environmental problem. Thus, extraction of these nutrients and its utilization in algae production can be a very good solution to this problem, and at the same time reducing the emissions associated with fertilizer production.

Oil is extracted from the algae, and further processed to biodiesel and other valuable products. The residual biomass from the algae production after oil extraction may be used as addition to fish meal production. In addition, the oxyfuel power production process will have an excess of thermal energy, which may be used in the fish meal production. Thus, an integration of a fish meal plant can improve the economy of the cluster further.  An example of a cluster is illustrated below.

The strong synergies between the different plants in the cluster may improve the economy in the different production processes significantly. Thus, it will be possible to realize environmentally friendly industry activities which otherwise would not be profitable enough for investment capital.

Marine Cluster utilizes all waste materials and by-products from the processes in the various production facilities, and have zero hazardous emission to water, air or earth.
