Life-Cycle Assessment of Microalgal-Based Biofuels
Fossil fuel depletion and attempts of global warming mitigation have motivated the development of biofuels. Several feedstock and transformation pathways into biofuel have been proposed as an alternative to usual fuels. Recently, microalgae have attracted a lot of attention because of the promise of reduced competition with food crop and lowered environmental impacts. Over the last years, sever...
متن کاملBiofuels from Algae
Algae can provide a variety of fuels for transport, heating or electricity generation, including biodiesel, aviation fuel and biogas. Algal biofuels are at an experimental stage and are more expensive than fossil fuels. Algal biofuels could be made more costeffective by extracting other valuable products from algae or incorporating their production into waste water treatment. Commercial...

متن کاملReview Transport biofuels – a life-cycle assessment approach
Life-cycle studies of the currently dominant transport biofuels (bioethanol made from starch or sugar and biodiesel made from vegetable oil) show that solar energy conversion efficiency is relatively poor if compared with solar cells and that such biofuels tend to do worse than conventional fossil transport fuels as to the emission of eutrophying and acidifying substances. Lifecycle studies of ...
متن کاملMicroalgae to biofuels: life cycle impacts of methane production of anaerobically digested lipid extracted algae.
This study presents experimental measurements of the biochemical methane production for whole and lipid extracted Nannochloropsis salina. Results show whole microalgae produced 430 cm(3)-CH4 g-volatile solids(-1) (g-VS) (σ=60), 3 times more methane than was produced by the LEA, 140 cm(3)-CH4 g-VS(-1) (σ=30). Results illustrate current anaerobic modeling efforts in microalgae to biofuel assessme...
