In: Energy for Sustainability 2015: Sustainable Cities: Designing for People and the Planet, Coimbra, Portugal, 14-15 May, 2015, 8 p.http://hdl.handle.net/10400.9/3007Microalgae are an attractive way to produce biofuels due to the ability to accumulate lipids and very high photosynthetic yields. This article presents a review of life-cycle assessment studies of microalgae biodiesel production, including an analysis of modeling choices and assumptions. A high variation in GHG emissions (between -0.75 and 2.9 kg CO2eq MJ-1) was found and the main causes were investigated, namely modeling choices (e.g. the approach used to deal with multifunctionality), and a high parameter uncertainty in microalgae cultivation, harvesting and oil extraction processes.engGreenhousesPhotobioreactorsLife cycle assessmentMicroalgaeBiodiesel Productionconference object
