Microalgae mass cultures could contribute to the mitigation of greenhouse gas (GHG) emissions by enabling the direct utilization of fossil CO 2 streams from concentrated sources and the production from the algal biomass of renewable biofuels and fossil fuel-sparing products. EniTecnologie, the R&D arm of the Italian oil & gas company Eni, is carrying out an in-house R&D project focused on demonstrating and improving on the achievable biomass productivities of outdoor microalgale mass cultures

The objective is toWe evaluated the feasibility of fixing flue gas CO 2 from a natural gas combined cycle (NGCC) power plant and to produce renewable methane fuel to replace a fraction of the input fossil methane of input. Initial experiments at the EniTecnologie R&D Centre in Monterotondo, central Italy, compared the productivity of thea marine microalga, Tetraselmis suecica, mass cultured in an outdoor experimental system consisting of a scale-down system that design simulatesing a large-scale microalgae production systems and comprisesing both open ponds and closed photobioreactors. RThe results indicated that closed and open cultivation systems have similar productivities, , and that in open ponds the areal values are close to the maximal productivities so far reported under outdoor operating conditions and significantly higher than those using flue gas CO 2 in similar scale-down systems. This R&D activity is being coordinated with other projects on microalgae mass cultures for biofixation of CO 2 througha constituent project of the International Network on Biofixation of CO 2 and GHG Abatement with Microalgae, an initiative that operates under the auspices of the IEA GHG R&D Programme.
