U-M study finds crop-based biofuels associated with net increase in GHGs; falsifying the assumption of inherent carbon neutrality

August 25, 2016

A new study from University of Michigan researchers challenges the assumption that crop-based biofuels such as corn ethanol and biodiesel are inherently carbon-neutral—i.e., that only production-related greenhouse gas (GHG) emissions need to be tallied when comparing them to fossil fuels.

In an open-access paper published in the journal Climatic Change, the researchers conclude that once estimates from the literature for process emissions and displacement effects including land-use change are considered, US biofuel use to date is associated with a net increase rather than a net decrease in CO2 emissions.

Biodiesel from engineered sugarcane more economical than from soybean

March 18, 2016

A techno-economic analysis by a team from the University of Illinois at Urbana Champaign and Virginia Polytechnic Institute and State University has determined that biodiesel produced from oil from genetically modified lipid-producing sugarcane (lipid-cane) is much more economical than biodiesel produced from soybean oil.

In their open-access paper, published in the journal Biofuels, Bioproducts & Biorefining, the researchers reported results showing that the biodiesel production cost from lipid-cane decreased from $0.89/L to $0.59 /L as the lipid content in the cane increased from 2 to 20%; this cost was lower than that obtained for soybeans ($1.08/L).

EPA nudges up volume of renewable fuel in final requirements for 2014-2016 under RFS

November 30, 2015

The US Environmental Protection Agency (EPA) announced the final volume requirements under the Renewable Fuel Standard (RFS) program today for the years 2014, 2015 and 2016, and final volume requirements for biomass-based diesel for 2014 to 2017.

This rule finalizes higher volumes of renewable fuel than the levels EPA proposed in June (earlier post), but still represents a reduction compared to the original statutory requirements.

EPA: jatropha-based biofuels could qualify as biomass-based diesel or advanced biodiesel under RFS

October 19, 2015

Based on its analysis of the production and transport components of the lifecycle greenhouse gas emissions of biofuel made from jatropha oil, the US EPA anticipates that biofuels produced from jatropha oil could qualify as biomass-based diesel or advanced biofuel under the Renewable Fuel Standard program if typical fuel production process technologies or process technologies with the same or lower GHG emissions are used. EPA has published its analysis in the Federal Register and is inviting comment.

Background. The RFS regulations lists three critical components of an approved fuel pathway: (1) Fuel type; (2) feedstock; and (3) production process. EPA uses lifecycle analysis to assess the overall greenhouse gas (GHG) impacts of a fuel throughout each stage of its production and use.

DLR-led NEMESIS 2+ project develops compact direct steam reformer for diesel/biodiesel to H2

September 02, 2015

The European NEMESIS 2+ consortium has and successfully tested a pre-commercial on-site system for the production of hydrogen from diesel and biodiesel. The prototype system—the size of a shipping container—can be integrated into existing infrastructure with relative ease.

The prototype, built by the Dutch project partner HyGear, produces 4.4 kilograms of hydrogen from 20 liters of biodiesel per hour—this roughly corresponds to the fuel tank of a B-Class F-cell vehicle. The efficiency of the process, from start to finish, is approximately 70%. (Original project goals were 50 Nm3/h, or 4.5 kg/h with an efficiency >80%.) The EU NEMESIS 2+ project, which ran until June 2015, was coordinated by the German Aerospace Center (DLR).

Lux: Despite softness in utilization, global biofuels capacity to grow to 61.4 BGY in 2018; driven by novel fuels and feedstocks

August 31, 2015

The global biofuels industry averaged 68% in utilization rate from 2005 to 2014, reached a high of 80.9% in 2007, dropped to a low of 56.9% in 2012, and climbed slightly back to 60.4% in 2014. Despite the still apparent softness in capacity utilization, and the on-going softness in fossil fuel prices, global biofuels capacity will continue to grow from 55.1 billion gallons per year (BGY) to 61.4 BGY in 2018, according to a forecast by Lux Research. However, Lux predicts, growth between now and 2018 will not be a continuation of current course.

While ethanol and biodiesel will continue to dominate in absolute terms, these will grow at only a 1.5% CAGR through 2018. Novel fuels and feedstocks will drive the biofuels industry forward at a much more rapid 17% and 22% CAGRs through 2018, respectively.
