Global Bioenergies reports first production of green isobutene at demo plant

Green Car Congress

Global Bioenergies is now entering the final phase of demonstrating its technology for converting renewable carbon into hydrocarbons. It can also be converted into isododecane, a compound found in jet fuel. Earlier post.). Isobutene—one of the main petroleum derivatives—is a platform molecule.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ).

Biosyncrude Gasification Process Could Produce Motor Fuel at Cost of Around $3/gallon

Green Car Congress

A crude oil price of US$100/bbl results in an approximate cost of €0.56/L Biomass is pyrolized to a pyrolysis oil. The pyrolysis oil is mixed with pyrolysis coke from the process to create a biocrude slurry for transport and subsequent gasification to syngas and subsequent catalytic conversion to chemicals and/or fuels.

Univ of Washington team working to make poplar coppice viable cheap, high-volume biofuel feedstock

Green Car Congress

The UW team is the first to try converting the entire young tree—leaves, bark and stems—into bio oil and ethanol using two separate processes. We have the environmental incentives to produce fuels and chemicals from renewable resources, but right now, they aren’t enough to compete with low oil prices.

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. They calculated production cost estimates assuming n th plant economics and without public investment support, CO 2 credits or tax assumptions.

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

Green Car Congress

A key barrier to achieving RFS2 is the high cost of producing biofuels compared to petroleum-based fuels and the large capital investments required to put billions of gallons of production capacity in place. If competition for bioenergy feedstocks intensifies because of low supply, the price will likely increase.

Study Finds Integrated Biorefinery Processes Could Be Highly Competitive With Petroleum Fuels on Efficiency and Costs, While Offering Substantial Reductions in Greenhouse Gas Emissions

Green Car Congress

The RBAEF project, which was launched in 2003, is the most comprehensive study of the performance and cost of mature technologies for producing energy from biomass to date. forest conversion) resulting from land-use considerations. Achieve production costs consistent with gasoline when oil prices are at about $30 a barrel.
