Algae PhotoBioreactor`s convert Carbon to Biofuels

Engineering designers from fishace technologies in Perth, Western Australia have developed a modular APB (Algae Photo Bioreactor) that can be placed at mine sites and power plant facilities to capture up to 85% of greenhouse gas emissions, blamed for global warming. APB’s captured gases include contaminants such as carbon dioxide and nitrous oxides.

CO2 produced from the combustion of carbon compounds such as coal and natural gas are captured and directed into the Algae Photo Bioreactor. The transparent module, contains the algae in nutrient enriched liquid suspension and when exposed to light allows the algae to undergo photosynthesis.

The CO2 converter system, grows algae in climate controlled closed transparent modules being part of their unique design and the focus of our development in Perth. The algae contained in these modules are harvested and mechanically pressed to recover the biodiesel.

The by-products from this closed carbon capture process are water, oxygen and algal cake a high protein feedstock that can be converted into high value pharmaceutical products such as Astaxanthin an antioxidant and Beta-carotene.

Dubbed the ‘Carbon Eater’ - the technology has been developed by Ecological Engineer, Stephen Bedford Clark, Environmental Designer Peter Galloway and Environmental Scientist Jason Haydock.

'Micro Algae are the fastest photosynthesising organisms known to man. They can complete an entire growing cycle every few days and can produce 100 times more oil per hectare/year than conventional soil based crops that are now being grown for biofuel use,' says Stephen Clark.

Fishace plans to commercialise the technology over the course of the year and expects to be able to compete commercially with the wholesale price of crude petroleum in the future. The consultancy, is developing commercial partnerships to develop technology and mass-produce APB’s and are engaged in the research and development of algae cultivation as a sustainable energy source.

This modular, patent-pending sequestration system offers a cost effective way to grow algae and optimises oil production. ‘By reducing the costs of energy input and initial capital outlay, the promise of algae based biofuels that are price-competitive with petroleum fuels is within our grasp’ says Peter Galloway.

Using Algae Photo-Bioreactors in industrial activities provides companies with a number of positive outcomes: greatly reduced CO2 emissions, algae to produce hydrogen, fats, oils, sugars and functional bioactive compounds for use and resale, emission credits, government tax subsidies, environmental compliance, production of O2 and a cleaner corporate image.
