GreenFuel Technologies Corporation, developers of algae bioreactor systems that recycle CO2 in smokestack gases into biofuels (earlier post), has signed a licensing agreement with The Victor Smorgon Group headquartered in Melbourne, Australia.
The agreement provides The Victor Smorgon Group with an exclusive license to distribute, install and operate GreenFuel’s Emissions-to-Biofuels (E2B) proprietary technology for growing, harvesting, and processing biomass and products derived from algae throughout Australia and New Zealand. The financial terms of the agreement were not disclosed.

GreenFuel retrofits its E2B process to flue stacks. Flue gas or other CO2-rich gas streams flow into the bioreactor, in which algae are suspended in a media with nutrients added to optimize the growth rate. A portion of the media is withdrawn continuously from the bioreactor and sent to a two-stage dewatering process to harvest the algae.
The primary dewatering increases the algae concentration by a factor of 10-30. Secondary dewatering further increases the algal solids concentration to yield a cake suitable for conventional downstream processing into biofuels.
|Downstream processing options for harvested algae|
|Fermentation||Ethanol and bioplastics|
|Anaerobic digestion||Biogas (methane)|
|Gasification and reforming||Hydrogen and Fischer-Tropsch fuels (BTL)|
Data from field testing of the system in 2004 and 2005 show a CO2 reduction of 82.3% ±12.5% on sunny days and of 50.1% ±6.5% on cloudy days. NOx emissions dropped 85.9% ±2.1% on both sunny and cloudy days. (CO2 reduction was measured from 9am to 5pm; NOx 24 hrs/day.)
A number of companies have tackled using algae in bioreactors. GreenFuel differentiates itself by the technology used for algae adaptation (derived from a NASA project for the International Space Station), a bioreactor design that is inexpensive to manufacture and to operate, and an analytical method for optimally exposing algae to sunlight—all of which have patents pending.
Founded in 1995, The Victor Smorgon Group owns and operates a diversified portfolio of companies in Australia and New Zealand. The company has investments in the manufacturing of biodiesel and plastics, aquaculture, and clothing retailing. The group also has substantial experience in waste recycling, having successfully implemented recycling processes in the paper, glass, steel, and plastics industries.
