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…

Microalgae can grow in waste or seawater, have vastly superior biomass yields per hectare and, most importantly, the CO2 removed from the atmosphere during photosynthetic growth of the plant offsets

Sustainable Integration of Algal Biodiesel Production with Steam Electric Power Plants for Greenhouse Gas Mitigation

Significant reductions in anthropogenic greenhouse gas (GHG) emissions, particularly of fossil carbon dioxide (CO2), are necessary worldwide in order to prevent adverse impacts of global climate

Environmental sustainability of emerging algal biofuels: A comparative life cycle evaluation of algal biodiesel and renewable diesel

Holistic evaluation via a life cycle based approach is critical for guiding the environmentally conscious development of emerging microalgal biofuel pathways. This study models the energy return on

Life-Cycle Energy Use and Greenhouse Gas Emissions Analysis for Bio-Liquid Jet Fuel from Open Pond-Based Micro-Algae under China Conditions

A life-cycle analysis (LCA) of greenhouse gas (GHG) emissions and energy use was performed to study bio-jet fuel (BJF) production from micro-algae grown in open ponds under Chinese conditions using

Techno-economic assessment of carbon-negative algal biodiesel for transport solutions

Effects of ethanol on vehicle energy efficiency and implications on ethanol life-cycle greenhouse gas analysis.

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.

Life‐cycle impacts of soybean and algae biodiesel: Case study of US marine vessels

The push to find alternatives to fossil fuels has driven research and consumption of biofuels. Recent actions in the United States have placed an emphasis on the use of renewable fuels for improved



Net energy and greenhouse gas emission evaluation of biodiesel derived from microalgae.

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.

Second Generation Biofuels: High-Efficiency Microalgae for Biodiesel Production

The use of fossil fuels is now widely accepted as unsustainable due to depleting resources and the accumulation of greenhouse gases in the environment that have already exceeded the “dangerously

Environmental, economic, and energetic costs and benefits of biodiesel and ethanol biofuels.

Transportation biofuels such as synfuel hydrocarbons or cellulosic ethanol, if produced from low-input biomass grown on agriculturally marginal land or from waste biomass, could provide much greater supplies and environmental benefits than food-basedBiofuels.

Microalgal Biomass for Greenhouse Gas Reductions: Potential for Replacement of Fossil Fuels and Animal Feeds

Microalgal biomass production offers a number of advantages over conventional biomass production, including higher productivities, use of otherwise nonproductive land, reuse and recovery of waste

Life cycle energy and greenhouse gas analysis for agave-derived bioethanol

The sustainability of large-scale biofuel production has recently been called into question in view of mounting concerns over the associated impact on land and water resources. As the most
