New report suggests bioenergy crops are not a risk to food production
http://www.greencarcongress.com/2016/06 ... nergy.html

In a new report, researchers have challenged the belief that growing crops for bioenergy will cut food production, a concern they say is stalling new schemes. The report also identifies five ways that countries as diverse as the United States and Brazil can achieve their targets to increase energy security, foster rural economic development and reduce greenhouse gas emissions.

Experts contributed from ten institutions across Africa, Europe and America, including the US Department of Energy’s Oak Ridge National Laboratory (ORNL), the International Food Policy Research Institute (IFPRI), the World Bank and Imperial College London in the UK. . . .

I'll have to find time to read the report, http://onlinelibrary.wiley.com/doi/10.1 ... 12366/full

as the knowledge I've acquired to date indicates the opposite.


Nice Report. I appreciate this statement I pulled from the Abstract,

"Simplistic global analyses, headlines, and cartoons that blame biofuels for food insecurity may reflect good intentions but mislead the public and policymakers because they obscure the main drivers of local food insecurity and ignore opportunities for bioenergy to contribute to solutions. "

Lux: biojet fuel to account for 56% of targeted 2050 CO2 emissions reductions in aviation
http://www.greencarcongress.com/2016/07 ... 9-lux.html

Biojet fuels will be key to achieving the aviation industry’s pledge to cut CO2 emissions to 0.2 billion tons (GT) in 2050—half the 2005 figure—as opposed to the staggering 2.1 GT projected by current growth rates, according to a new report from Lux Research, “Biojet Fuel Technology Roadmap.”

Lux forecasts that biojet fuel innovations, led globally by Honeywell UOP and Boeing, will account for 56% of the targeted CO2 emissions reductions, while a third of the requisite cuts will come from new aircraft technology, and optimization of operations and infrastructure. . . .

US releases Federal alternative jet fuels R&D strategy
http://www.greencarcongress.com/2016/07 ... fajfs.html

. . . The strategy provides a prioritized list of R&D goals and objectives addressing specific scientific, technical, analytical, and logistics challenges that hinder the development, production, and wide-scale economic deployment of AJFs. In releasing the FAJFS, the federal government hopes to accelerate the development of the AJF industry by minimizing technical uncertainty to encourage further private sector interest, facilitate the development and approval of new AJF pathways, and reduce the cost of AJF production in the United States. . . .

Going forward it will lead implementation of the strategy, analyze ongoing federal efforts, and collaborate with federal and non-federal stakeholders, including the Commercial Aviation Alternative Fuels Initiative (CAAFI), in advancing four thematic areas of the strategy:

    feedstock development, production, and logistics;
    fuel conversion and scale-up;
    fuel testing and evaluation; and
    integrated challenges such as sustainability. . . .

US Navy completes sea trial with ARA’s 100% drop-in renewable diesel fuel
http://www.greencarcongress.com/2016/08 ... 9-ara.html

. . . ReadiDiesel was developed by Applied Research Associates (ARA) and Chevron Lummus Global, as a drop-in replacement for petroleum F-76 marine diesel. ReadiDiesel is a 100% renewable biofuel. (Earlier post.)

The SDTS took on approximately 18,000 gallons of ReadiDiesel in San Diego, California. The objective of this particular test was twofold: first, to demonstrate that ReadiDiesel is a drop-in replacement for petroleum-sourced F-76 marine diesel, meaning that it requires no blending with petroleum-derived fuels, equipment modifications or operational modifications by the crew; and second, to ensure that this renewable fuel performs equally to, or better than, existing petroleum-derived fuels.

The renewable diesel fuel powered the Self Defense Test Ship’s General Electric LM-2500 gas-turbine engine and a Rolls Royce 501 K-17 gas-turbine generator.

The test period lasted approximately 12 hours along the Southern California Coast, while enroute from San Diego to Port Hueneme. Navy engineers monitored the performance of the gas-turbine engines and generators while running on petroleum F-76 prior to taking on the ReadiDiesel to establish a baseline for comparison. . . .

Argonne team finds significant albedo warming effect for switchgrass ethanol
http://www.greencarcongress.com/2016/08 ... lbedo.html

One of the key points of contention over the climate benefit of biofuels is the impact of land use change (LUC) associated with biofuel feedstock production. LUC results in biogeochemical (e.g., soil organic carbon) and biogeophysical (e.g., surface albedo, evapotranspiration, and surface roughness) changes. Of the biogeophysical factors, surface albedo has been considered a dominant effect at the global scale.

A team at Argonne National Laboratory has now quantified land use change (LUC)-induced albedo effects for three major biofuels in the US, using satellite data products for albedo and vegetation observations. Published in the RSC journal Energy & Environmental Science, the analysis indicates that the land use change (LUC)-induced albedo effect is small for corn and miscanthus ethanol, but is significant for switchgrass ethanol, which is driven by the types, locations, and intensities of various land conversions to these biofuel feedstocks. . . .

With the LUC-induced albedo effect included, ethanol from corn, switchgrass, and miscanthus has life-cycle GHG emissions of 56, 29, and -4 g/MJ, respectively. These results translate to a GHG emission reduction of about 39%, 68%, and 104%, respectively, relative to petroleum-derived gasoline, which has a GHG emission intensity of 92 g CO2e/MJ. . . .

U-M study finds crop-based biofuels associated with net increase in GHGs; falsifying the assumption of inherent carbon neutrality
http://www.greencarcongress.com/2016/08/20160825.html

. . . 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.

The study, based on US Department of Agriculture crop-production data, shows that during the period when US biofuel production rapidly ramped up, the increased carbon dioxide uptake by the crops was only enough to offset 37% of the CO2 emissions due to biofuel combustion over the period 2005-2013. . . .

The researchers applied Annual Basis Carbon accounting to investigate the changes in carbon flows directly associated with a vehicle-fuel system. Unlike LCA or other forms of carbon accounting used for climate policy to date, ABC does not treat biofuels as inherently carbon neutral; it tallies CO2 emissions on the basis of chemistry in the specific locations where they occur.

ABC accounting reflects the stock-and-flow nature of the carbon cycle,— i.e., that changes in the atmospheric stock depend on both inflows and outflows. LCA, on the other hand, focuses only on inflows (GHGs discharged into the atmosphere).

The system in the study was defined to include motor fuel consumption, fuel processing operations and resource inputs, including cropland for biofuel feedstocks. . . .

Some funding for the study was provided by the American Petroleum Institute.

Technip signs agreement with BTG Bioliquids to design and build pyrolysis plants for biomass-to-oil production

Technip has signed an exclusive cooperation agreement with BTG BioLiquids B.V. (BTL) to provide EPC (engineering, procurement and construction services) for its modular pyrolysis plants. The plants will be based on BTL’s Fast Pyrolysis Oil (FPO) technology which converts biomass to oil through a rapid pyrolysis process.

The fast pyrolysis technology mixes biomass particles and hot sand in a reactor which transforms the material into pyrolysis oil. This oil can be used as a sustainable alternative to fossil fuels for the production of renewable energy and chemicals. . . .
