Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

Spatially explicit life cycle assessment of 5 sun-to-wheels pathways finds photovoltaic electricity and BEVs offer land-efficient and low-carbon transportation

Green Car Congress

A new spatially-explicit life cycle assessment of five different “sun-to-wheels” conversion pathways—ethanol from corn or switchgrass for internal combustion vehicles (ICVs); electricity from corn or switchgrass for battery-electric vehicles (BEVs); and photovoltaic electricity for BEVs—found a strong case for PV BEVs.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

Increased availability of low CO 2 sources of electricity and hydrogen could counter-intuitively delay, rather than accelerate, a large-scale transition to an electric and/or hydrogen vehicle fleet, according to a new study by researchers from Ford Motor Company and Chalmers University of Technology in Sweden. Anderson, S. Mueller, M.

Tsinghua Study Finds That Conventional Three-Way Catalyst Can Handle the Unregulated Emissions from Low-Content Methanol-Gasoline Blends

Green Car Congress

However, the use of coal-generated methanol as a practical alternative fuel is one of the most realistic options for China, because of the “oil-lean, gas-lacking, and coal-rich” structure of Chinese energy resources. Energy Fuels , Article ASAP doi: 10.1021/ef900974p. —Fan et al.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Researchers at the Norwegian University of Science and Technology (NTNU) are proposing a new process for producing synfuel from biomass using concentrating solar energy as its main energy source. For comparison, they also modeled the production of methanol using only biomass as a fuel and also using coal as source of both carbon and energy.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is. A year ago, we weren’t even having this conversation.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes).
