Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

A co-production scenario—yet to be commercial—would take unconverted syngas from the FT reactor and combust it in a combined cycle power plant to generate electricity that is sold to the grid. Even with CCS, the liquid product costs are comparable to recent crude oil prices. Source: Mantripragada and Rubin.

GE Aviation testing 100% Gevo Alcohol-to-Jet fuel

Green Car Congress

With the successful scale-up of this technology, it is believed that Gevo’s HEDFs could be produced at a lower cost than the petroleum-based equivalent, even at current oil prices. HEDFs are currently used in air and sea-launched cruise missiles used by the US military forces. Patrick Gruber, Gevo’s CEO.

Study finds no alternative to widespread switching of direct fuel uses to electricity to meet 2050 California GHG targets; putting detail in climate wedges

Green Car Congress

Technically feasible levels of energy efficiency and decarbonized energy supply alone will not be sufficient to reduce greenhouse gas emissions 80% below 1990 levels by 2050, according to a detailed modeling of the California economy performed by a team from Energy and Environmental Economics, the Monterey.

EIA 2035 reference case projects drop in US imports of petroleum due to modest economic growth, increased efficiency, growing domestic oil production, and biofuels

Green Car Congress

EIA’s AEO2012 projects a continued decline in US imports of liquid fuels due to increased production of gas liquids and biofuels and greater fuel efficiency. EIA added a premium to the capital cost of CO 2 -intensive technologies to reflect current market behavior regarding possible future policies to mitigate greenhouse gas emissions.

EIA Energy Outlook 2013 reference case sees drop in fossil fuel consumption as use of petroleum-based liquid fuels falls; projects 20% higher sales of hybrids and PHEVs than AEO2012

Green Car Congress

Energy consumption by LDVs (including commercial light trucks) declines in the Reference case, from 16.1 Sales of battery-powered electric vehicles are 65% lower in the AEO2013 Reference case than the year before, with annual sales in 2035 estimated to be about 119,000. Biofuels grow at a slower rate due to lower crude oil prices and.

Roland Berger study outlines integrated vehicle and fuels roadmap for further abating transport GHG emissions 2030+ at lowest societal cost

Green Car Congress

To further abate GHG emissions in road transport by 2030, more biofuels and hybrid powertrains for passenger cars as well as more biofuels and new truck concepts for commercial vehicles are a cost effective way of delivering more GHG savings from transport and with supportive polices they can deliver an extra 34 Mt CO 2 e by 2030.
