Cobelec™: Electricity from Ag. Residues
The Cobelec™ business plan presentation outlines a cleantech investment for renewable energy made from agricultural residues. In September 2010, our business plan was recognised as runner-up in a clean energy financing forum.
A pre-feasibility study has been performed that shows that the conversion of 60,000 tonne/year agricultural residues can be converted into 7MW electricity. The conversion technology employed is gasification which produces a combustible gas that is used in a specialised gas engine (GE Jenbacher or similar).
After the competition, due to the difficult regulatory environment in South Africa, interested investors asked for investigation into alternative products (i.e. not electricity) which we have completed. These products include hydrogen, bio-SNG (Synthetic Natural Gas) and ammonia. To compliment this plant, a bio-based chemicals plant has also been proposed in a separate project (Cobchem™) where a portion of the biomass will be extracted and converted to furfural prior to gasification. Should the gasification be used to form hydrogen, furfural alcohol could be another product that this processing complex (GreenEnergyPark™) could manufacture.
The direction of this project and final configuration of the plants will depend on the interest of investors and at this stage is flexible.
