Nature's Solution to Climate Change
Cyanobacteria are photosynthetic, aquatic microalgae that produce 50% of the world’s oxygen. The photosynthetic efficiency in these organisms is far superior to that of plants and therefore possess an untapped potential for scalable carbon capture.
We harness the power of genetic modification (GM) to 3X the rate of carbon fixation of wild-type strains*. Our unique triple-target GM plan drives the net bicarbonate influx into the cell through an undisclosed transporter protein, upregulates the light-harvesting mechanisms, and creates a perpetual efflux of carbon-dense bioproducts from the cell. This carbon that would otherwise be converted into biomass in a slow-step, is instead directed towards the synthesis of a host of high value bioproducts by our unique proprietary cyanobacterial strains. Altogether, we create a highly efficient 'biological factory' for the sole purpose of maximising carbon fixation.
A breakthrough in Bioengineering:
Tripling the rate of carbon capture
A new class of Photobioreactor design
Efficient photobioreactor design is essential to maximising light-harvesting. Reactors require short path-length, high surface area-volume ratio and good optical transparency. Our low-cost closed raceway pond, featuring our unique reactor-in-series design enables maximum surface area for light-dependent reactions and CO2 gas-recycling. Concentrated CO2 extracted from industrial flue gases is directly bubbled through the long network of photobioreactors before leaving the system as a mixed gas comprised of a much lower ppCO2 and higher ppO2.
A precise control photobioreactor
Flue gases leave the industrial stack at 150-400C. By using a steady input of hot CO2 cooled with ambient air, we maintain the photobioreactor at the optimum temperature with negligible heating costs. Our breakthrough technology brings the net CCS cost to below €50/tCO2 captured - a significant advantage compared to our competitors. Every 72 hours, the excess volume in the reactor comprised of the insoluble carbon-dense bioproduct and excess biomass growth is drained through an outlet and replaced with fresh media derived from sterilised nitrate-enriched sewage water.
