The National Bioeconomy Blueprint describes five strategic objectives for a bioeconomy with the potential to generate economic growth and address societal needs. 1. Support R&D investments that will provide the foundation for the future U.S. bioeconomy.“Coordination of Federal bioeconomy-related research activities can improve the efficiency and effectiveness of those investments and is especially important when [...]

Trading firm sues US EPA over Renewable Identification Number (RIN) biofuel program

CLEAN GREEN SCAMBiofuel producers and oil refiners were roiled last October when the federal government charged Rodney Hailey, the owner of Clean Green Fuel, with carrying out a $9 million scam involving the distribution of 32 million fake credits, or renewable identification numbers.Oil companies are required to purchase RIN credits from producers of renewable fuel [...]

OriginOil’s algae harvest technology removes 98% of hydrocarbons from frac flowback

In California, OriginOil reports that, in recent independent third-party testing, the company’s algae harvesting process was able to remove 98% of hydrocarbons from a sample of West Texas oil well ‘frac flowback’ water in the first stage alone. Frac flowback describes water used in a drilling process called ‘hydraulic fracturing’, or ‘fracking’.This test sample was [...]

A Nation-Sized Battery?

The Intermittency Challenge and the approaching need for massive storage of rapidly dispatchable energy has led the concept of the National Battery, a unified facility that holds the aggregated outputs from an array of intrinsically episodic renewable sources, releasing energy as demand requires. In this contribution, the original demonstration of Murphy that lead-acid batteries are [...]

An assessment of greenhouse gas emissions-weighted clean energy standards versus renewable portfolio standards

This paper quantifies the relative cost-savings of utilizing a greenhouse gas emissions-weighted Clean Energy Standard (CES) in comparison to a Renewable Portfolio Standard (RPS). Using a bottom-up electricity sector model for Hawaii, this paper demonstrates that a policy that gives “clean energy” credit to electricity technologies based on their cardinal ranking of lifecycle GHG emissions, [...]

The role of bioenergy in a fully sustainable global energy system

We find that the potential for sustainable bioenergy from residues and waste, complementary fellings, energy crops and algae oil in 2050 is 340 EJ a−1 of primary energy. This potential is then compared to the demand for biomass-based energy in the demand scenario related to this study, the Ecofys Energy Scenario [1]. This scenario, after [...]

EPA approves E15 ethanol blend registrations

In Washington, The U.S. Environmental Protection Agency approved the first applications for registration of e hanol for use in making gasoline that contains up to 15 percent ethanol – known as E15.To enable widespread use of E15, the Obama Administration has set a goal to help fueling station owners install 10,000 blender pumps over the [...]
