The search for alternative fuels to alleviate our dependency on fossil-based transport fuels is driven by depleting conventional oil resources and looming climate change induced by anthropogenic greenhouse gas (GHG) emissions. Through a lifecycle approach, we evaluate whether algal biodiesel production can be a viable fuel source once the energy and carbon intensity of the process is managed accordingly. Currently, algae biodiesel production is 2.5 times as energy intensive as conventional… Expand

Effects of ethanol on vehicle energy efficiency and implications on ethanol life-cycle greenhouse gas analysis.
TLDR
It is argued that due to the increased emphasis on alternative fuels with drastically differing energy densities, vehicle efficiency should be evaluated based on energy rather than volume, and shows that efficiency of existing vehicles can be affected by ethanol content. Expand
Life cycle assessment of algae biodiesel and its co-products
TLDR
Life cycle assessment of algae biorefinery considering selected multi-products revealed less CO2 emissions and land use for biodiesel, protein and succinic acid production system compared to that of only biodiesel and protein production system from algae. Expand

Net energy and greenhouse gas emission evaluation of biodiesel derived from microalgae.
TLDR
This study proposes a detailed, industrial-scale engineering model for the species Nannochloropsis using a photobioreactor architecture that is integrated with a lifecycle energy and greenhouse gas emission analysis compatible with the methods and boundaries of the Argonne National Laboratory GREET model, thereby ensuring comparability to preexisting fuel-cycle assessments.
