Purdue analysis finds H2Bioil biofuel could be cost-competitive when crude is between $99–$116/barrel

Green Car Congress

The Purdue University-developed fast-hydropyrolysis-hydrodeoxygenation process for creating biofuels—H 2 Bioil ( earlier post )—could be cost-competitive when crude oil prices range from $99 to $116 per barrel, depending upon the source of hydrogen, the cost of biomass and the presence or absence of a federal carbon tax, according to a new study by the Purdue team. Their analysis is published in the journal Biomass Conversion and Biorefinery.

VTT study concludes gasification-based pathways can deliver low-carbon fuels from biomass for about 1.90-2.65 US$/gallon

Green Car Congress

The horizontal red lines show the comparable price of gasoline (before tax, refining margin 0.3 $/gal, exchange rate: 1 € = 1.326 $) with crude oil prices 100 $/bbl and 150 $/bbl. The investigation was focused on gasification-based processes that enable the conversion of biomass to methanol, dimethyl ether, Fischer-Tropsch liquids or synthetic gasoline at a large (300 MW th of biomass) scale.

Sandia Labs/GM Biofuels Systems Study Concludes Large-Scale Production of Advanced Biofuels is Achievable and Sustainable

Green Car Congress

The simulations assume technological progress in the conversion technologies, which results in average biomass conversion yields of over 95 gallons of ethanol per dry ton of biomass by 2030. Conversion technologies are linked to feedstocks. In the study, conversion technologies are linked with specific feedstocks. For each new plant constructed, the BDM selected a feedstock/conversion pair resulting in the lowest cost of ethanol.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Further, the report found, only in an economic environment characterized by high oil prices, technological breakthroughs, and a high implicit or actual carbon price would biofuels be cost-competitive with petroleum-based fuels.The report also suggests that RFS2 may be an ineffective policy for reducing global GHG emissions because the effect of biofuels on GHG emissions depends on how the biofuels are produced and what land-use or land-cover changes occur in the process.

GAO Report Concludes Industry and Government Face Significant Challenges in Meeting RFS Target While Minimizing Unintended Adverse Effects; Suggests Federal Research Give Priority to Non-Ethanol Biofuels

Green Car Congress

Biofuels production has had mixed effects on US agriculture with respect to land use, crop selection, livestock production, rural economies, and food prices, the report found. For example, while increasing demand for corn for ethanol contributed to higher corn prices, thereby providing economic incentive for some corn producers, they also increased feed costs for livestock producers. tax credit is.

The report concludes that while the 1-million unit goal is ambitious, it is also achievable based on steps already taken as part of the Recovery Act along with proposed additional policy initiatives including improvements to existing consumer tax credits, programs to help cities prepare for the growing demand for electric vehicles, and strong support for research and development to continue reducing the cost of electric vehicles.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. The government assisted the shift by giving sugar companies subsidized loans to build ethanol plants, as well as guaranteeing prices for their ethanol products.

National Low Carbon Fuel Standard study releases major Technical Analysis and Policy Design reports; providing a scientific basis for policy decisions

Green Car Congress

The primary objectives of the National Low Carbon Fuel Standard (LCFS) Study were to (1) compare an LCFS with other policy instruments, including the existing Renewable Fuel Standard (RFS2) and a potential carbon tax, that have the potential to significantly reduce transportation greenhouse gas (GHG) emissions from fuel use; and (2) propose a policy structure for an LCFS that would be implementable, cost effective, and provide maximum economic gains to the consumers and the society.

Will be competitive at an oil price of $45 to $90 at their commercial date. This technology could avoid both the need for significant capital investment to upgrade refineries to produce more low sulfur fuel oil (LSFO) and greater dependence on costlier, low sulfur crudes. There are many players, and the oil industry (including Shell, ExxonMobil, BP, Valero and Chevron) is looking at a range of methods to eliminate steps in the process to reduce complexity and cost.

The Renault-Nissan Alliance and Project Better Place have signed a Memorandum of Understanding to create a mass-market for electric vehicles in Israel which is an excellent target market: it has a sales tax exceeding 60% for gasoline vehicles, gasoline costs over $6 per gallon, most driving fits the range of electric vehicles, and the government strongly supports energy independence. Millions of EVs and PHEVs would expand the sale of electricity as an alternative to oil.
