The key objective of the CO2ALGAEFIX project is to demonstrate, at a one hectare surface scale, an efficient way to capture CO2 from stationary sources (in this case, a power plant that uses natural gas). It aims to demonstrate that CO2 emissions can be used as a substrate for biomass algae production.
The project will use a 10.000 m2 pilot plant constructed by Algaenergy for experiments in microalgae cultivation. It aims specifically to test and demonstrate a new photobioreactor concept based on flat panels as the basis for a highly efficient large-surface culture plant. The process proposed will include novel technologies to capture and concentrate CO2, and make it available for culturing microalgae.
Through ongoing evaluation and optimisation of the pilot plant’s design, and its connection to the CO2-generation plant, the project hopes to achieve increased CO2 bio-fixation and the photosynthetic efficiency of microalgal cultures. The surface of 1ha of the demonstration plant is expected to capture and fix more than 200 tonnes of CO2 per year. If successful, the technology should easily scale-up to industrial level.
