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.

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.

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

Green Car Congress

Despite the expected reduction in cost of alternative technologies, the share of new car sales will remain relatively small; the influence of these technologies on overall emissions currently remains marginal. PHEVs fueled with advanced biofuels and low carbon, renewable electricity (for PC). 34 Mton CO 2 e (WTW). Roland Berger study.

MITEI releases report on Electrification of the Transportation System

Green Car Congress

The transportation sector thus represents a significant fraction of total greenhouse gas (GHG) emissions both globally and in the US—light-duty vehicles (LDVs) are responsible for 17.5% Electrification will also reduce oil dependence, providing foreign policy benefits and the potential to reduce real oil prices and oil price volatility.

Inaugural Quadrennial Technology Review report concludes DOE is underinvested in transport; greatest efforts to go to electrification

Green Car Congress

The DOE-QTR defines six key strategies: increase vehicle efficiency; electrification of the light duty fleet; deploy alternative fuels; increase building and industrial efficiency; modernize the electrical grid; and deploy clean electricity. DOE’s most significant role in transport research is here.

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

Green Car Congress

His paper, Kreutz noted, is only a preliminary scoping study designed to sketch out the rough outlines of each system’s prospective performance and economics as related primarily to GHG. Kreutz presented the paper at the 10 th International Conference on Greenhouse Gas Control Technologies ( GHGT-10 ) earlier this fall in The Netherlands.

Study Finds EVs Economically and Financially Viable in New South Wales, Australia Market Today

Green Car Congress

The study found that for small and medium passenger vehicles, expected lifetime cost per kilometer for EVs is already lower than that of conventional ICE. The total cost of ownership includes the vehicle price, annual fuel and maintenance costs and insurance. Future costs have been discounted at 7%. Source: AECOM.
