The ‘water footprint’ of bioenergy, i.e. the amount of water required to cultivate crops for biomass, is much greater than for other forms of energy. The generation of bioelectricity is significantly more water-efficient in the end, however – by a factor of two – than the production of biofuel. By establishing the water footprint for thirteen crops, researchers at the University of Twente were able to make an informed choice of a specific crop and production region. They published their results in the Proceedings of the National Academy of Sciences (PNAS) of 2 June.

The researchers found, for example, that it takes an average of 14,000 litres of water to produce one litre of biodiesel from rapeseed or soya. However, the water footprint for rapeseed in Western Europe is significantly smaller than in Asia. For soya, India has a large water footprint, while the figures for countries such as Italy and Paraguay are more favourable. In the generation of bioelectricity, too, there are big differences between the crops: sugar beet has by far the smallest water footprint – jatropha is 10 times less water-efficient. For the production of bioethanol, sugar beet is again by far the favourite: one litre of bioethanol made from sugar beet takes 1,400 litres of water, as against 2,500 litres for sugarcane, which is widely cultivated  in Brazil.  A new report from Novozymes describes how Brazil could produce up to 8 billion liters (2.1 billion gallons US) of biofuel from sugarcane residues (bagasse) by 2020, representing additional export revenue for Brazil of up to US$4 billion. In Brazil, the proportion of bioethanol used in transport fuel is already at 50%; by comparison, the proportion is 7% in the US, 2% in China, and 1% in Europe, according to Novozymes.

The Obama administration established a Biofuels Interagency Working Group this week in a move that carries implications for the industry on several fronts, including regulatory and research and development. 
 
The Biofuels Interagency Working Group, comprised of the U.S. Environmental Protection Agency, Department of Energy (DOE)  and Department of Agriculture, will develop a biofuel market development program, coordinate biofuel infrastructure policies, study biofuel lifecycle and help existing biofuel producers secure credit and refinancing.

Meanwhile, the DOE will spend $786.5 million in stimulus funds on demonstration projects and research to accelerate the adoption of next-generation biofuels. 

For example, the agency will dole out $480 million on 10 to 20 pilot-scale and demonstration-scale projects, with a ceiling of $25 million and $50 million, respectively. Another $176.5 million shall be used to increase funding for two or more commercial-scale biorefinery projects that previously received government assistance.

The DOE biomass program also will dedicate $130 million toward research into ethanol, algal biofuels and biofuel sustainability research.

The proposal breaks down renewable fuels into four categories: cellulosic biofuels, biomass-derived diesel, advanced biofuels, and total renewable fuel. The fuels must produce fewer greenhouse gas emissions than conventional fuels, but there is great debate within the biofuel industry about how these lifecycle assessments should be calculated.

$480 million solicitation for integrated pilot- and demonstration-scale biorefineries

Projects selected under this Funding Opportunity Announcement will work to validate integrated biorefinery technologies that produce advanced biofuels, bioproducts, and heat and power in an integrated system, thus enabling private financing of commercial-scale replications.

DOE anticipates making 10 to 20 awards for refineries at various scales and designs, all to be operational in the next three years.  The DOE funding ceiling is $25 million for pilot-scale projects and $50 million for demonstration scale projects.

These integrated biorefineries will reduce dependence on petroleum-based transportation fuels and chemicals. They will also facilitate the development of an “advanced biofuels” industry to meet the federal Renewable Fuel Standards.
