European Parliament Report Assesses Fuel Alternative Options, Including Biofuels

The Scientific Technology Options Assessment (STOA) body of the European Parliament has published a report called “Alternative Technology Solutions for Road and Air Transport”. In this report, the pros and cons of energy alternatives categorized into 5 technologies (hydrogen/fuel cells, battery electric vehicles, hybrid technology, biofuels and natural gas) were analyzed. With respect to biofuels, the report states that “second generation biofuels” (cellulosic ethanol and biomass-to-liquids technology) present a long term viable option. Biogas or biogas/natural gas blends for transport fuels are also a possible scenario. To meet Europe’s biofuel needs, biomass may have to be imported from abroad..
ICRISTAT Collaborative Program Realizes Ethanol Production from Sweet Sorghum while Benefiting Farmers without Compromising Food Security

A joint public-private partnership between ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) and Rusni Distilleries in India has successfully produced ethanol from sweet sorghum with the benefit of providing additional income to “resource-poor farmers from the drylands”. “Sweet sorghum ethanol” is now being produced at a distillery in Mohammed Shapur village in Andhra Pradesh, India. Dr. William Dar, ICRISAT Director General, says that the project successfully blends (1) ICRISAT's scientific capability in developing sweet sorghum varieties with higher juice availability, (2) the entrepreneurial capability of Rusni Distilleries, and (3) the effective linkage with the dryland farmers through the grass-roots networking strength” of partners like the Aakrithi Agricultural Associates of India (AAI). Under the program, the farmers (previously identified in village clusters) are given the sweet sorghum varieties for planting. Mechanisms are also in place to allow farmers to take their sweet sorghum stalk harvest to cluster centers where the stalks are crushed to extract the juice, converted into syrup, and then transported to Rusni Distilleries for ethanol production. According to ICRISAT, an additional source of income is provided to the farmers, while “they do not lose out on food security”. The stalks are processed into ethanol, while the grains can be used for food.

Switchgrass (Panicum virgatum) and Miscanthus (Miscanthus x giganteus) are two “C4” perennial grasses which have been reported to be promising cellulosic feedstocks for ethanol production in the United States. “C4” is one of 3 pathways that plants use to fix carbon dioxide into sugars by photosynthesis. However, which of these two grasses is better? Recently, the team of Frank Dohleman of the Plant Biology Department of the University of Illinois at Urbana-Champaign published their side-by-side field trial results, comparing the productivities of these two grasses. Overall, Miscanthus was shown to be more productive than switchgrass. Greater productivity means greater ethanol production potential. The following were the key attributes that may explain why Miscanthus produced more usable biomass relative to switchgrass: (1) 45% greater leaf area, (2) capability to gain more photosynthetic carbon per leaf area (33% greater than switchgrass), and (3) longer growing season (11 days longer than switchgrass).

Durum wheat is main raw material of Italian pasta and is reported to be one of the reasons that make Italian pasta taste good. The endosperm of Durum wheat gives pasta its characteristic yellow color. Although Durum wheat for pasta is sourced in Italy, the country is forced to import 40% of its supply (mainly from Canada and Syria), due to strong domestic demand and a growing export market. However, Syria recently banned the export of this commodity, and the wholesale price in Canada has increased due to new demand of the wheat as a biofuel feedstock. Consequently, Italian pasta manufacturers are warning of a 20% surge in pasta prices in autumn this year.
Global warming has been attributed to the productivity declines of Durum wheat in the Mediterranean. The Biopact website also describes another component of the problem, related to “European and American tariffs on imported ethanol, which allow durum wheat to be used as a raw material for ethanol”. More details are available at the Biopact website.
