[NEWS] DOE Schedules Meeting of Biomass Advisory Committee

– by Erin Voegele, October 30, 2017, Biomass Magazine

DOE_15093993318854-300x300-noup.jpThe U.S. Department of Energy has announced an open meeting of the Biomass Research and Development Technical Advisory Committee on Nov. 15-16 in Washington, D.C.

According to information published in the Federal Register, the meeting aims to develop advice and guidance that promotes research and development leading to the production of biobased fuels and products. The agenda is expected to include an update on USDA and DOE biomass research and development activities and presentations from industry, national laboratories, and federal agencies on improving feedstock supply chain cost and efficiency and upgrading of biomass into feedstocks.

[NEWS] New Study on Carbon Emissions from Bioenergy

Many climate policies and models consider biomass carbon-neutral. The argument is that carbon emitted during burning the biomass is balanced out by the carbon that plants and trees sequester. But that understanding is flawed.

Biomass is indeed renewable, and burning biomass or biomass-derived fuels can offset fossil fuel use. However, cultivating and harvesting biomass, transporting it, and processing it for energy or to make liquid fuels all emits greenhouse gases. Exactly how the biomass is used—whether directly or turned into fuel—also makes a difference.

[NEWS] Enzyme Shows Promise for Efficiently Converting Plants to Biofuels

To make biofuels, tiny microbes can be used to break down plant cells. As part of that digestive process, specialized enzymes break down cellulose—a major molecule that makes plant cell walls rigid. Scientists showed that an enzyme, from the bacterial glycoside hydrolase family 12, plays an unexpectedly important role in breaking down a hard-to-degrade crystalline form of cellulose. Surprisingly, the enzyme breaks apart the cellulose via a random mechanism unlike other hydrolases.

Breaking down cellulose is a major challenge in developing more efficient strategies for converting plant biomass to fuels and chemicals. The discovery of a specialized enzyme that is highly effective at breaking down rigid plant cell wall components could be harnessed to solve this challenge.

[NEWS] County-by-County Variability of Bioenergy Crop Yields in the U.S.

Using corn and soybeans as their testing ground, researchers at Pacific Northwest National Laboratory devised methods to peer into the mechanisms that modulate crop yield variability. They used statistical models to examine how climate variability impacts yields of these popular bioenergy crops at the county level. Among climate factors, the team showed that temperature is predominant in corn-growing counties, both by volume and percentage of production. Precipitation has a similar impact. The amount of energy from the sun, or radiation, has a much smaller effect USA-wide on both soybeans and corn.

Little Eagle Creek (Trey Crumbie)

Thousands of fish have been killed by 3,000 gallons of biodiesel that leaked into a river from a truck stop in Kentucky, US.

The diesel leaked into Little Eagle Creek near Sadieville in early to mid-November from a branch of the national Love’s Travel Stop chain of truck stops.

Jack Donovan, director of the Georgetown/Scott County Emergency Management Agency, told Lexington Herald Leader that the agency receive a notification of the leak on 18 November, but some locals said they had noticed the leak up to two week prior.

The cleanup of the leak, the exactly source of which has not bee determined, is in progress and will take a “long time”.

Government officials testified before the Senate on Thursday that sluggish development of ethanol and other biofuels has hampered attainment of the Renewable Fuel Standard.

Enacted in 2005, the Renewable Fuel Standard or RSF requires that all transportation fuel sold in the United States contain a minimum amount of renewable fuels.

The Senate Subcommittee on Regulatory Affairs and Federal Management called a hearing Thursday afternoon to look at two new reports from the Government Accountability Office on the standard’s feasibility.
