Life Cycle Assessment of Biofuels

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...

Review 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 ...

Life-cycle assessment of transportation biofuels from hydrothermal liquefaction of forest residues in British Columbia

Background Biofuels from hydrothermal liquefaction (HTL) of abundantly available forest residues in British Columbia (BC) can potentially make great contributions to reduce the greenhouse gas (GHG) emissions from the transportation sector. A life-cycle assessment was conducted to quantify the GHG emissions of a hypothetic 100 million liters per year HTL biofuel system in the Coast Region of BC....
