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 ).

Global Bioenergies reports first production of green isobutene at demo plant

Green Car Congress

With a nameplate capacity of 100 tons/year, the demo plant will allow the conversion of various resources (industrial-grade sugar from beets and cane, glucose syrup from cereals, second-generation sugars extracted from wheat straw, bagasse, wood chips…), into high-purity isobutene. Earlier post.).

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

Green Car Congress

Earlier studies show that poplar woodchips are a viable biofuel source, but costs still don’t pencil out, especially since trees are cut just once every 10-plus years. Additionally, other tree parts go to waste when only the trunk is used, making the process more inefficient and wasteful. That’s the problem. Chang Dou, Devin S.

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.

Will be competitive at an oil price of $45 to $90 at their commercial date. The biggest challenge is in the deconstruction stage, with high costs for pretreatment and enzymes. These costs have to go down, but improvements will come from optimizing the whole system, from feedstock to production. Waste-to-fuel.

CAR releases study on use of bio-based materials in automotive sector; potential for the Great Lakes Region

Green Car Congress

The report defines bio-based materials as industrial products made from renewable agricultural and forestry feedstocks, which can include wood, grasses, and crops, as well as wastes and residues. These feedstocks are usually fermented and go through a series of conversions to produce polymers that can be used in plastic composites.

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.
