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).

Study finds co-producing FT fuels and electricity from coal and biomass with CCS delivers low GHG synfuels at lower cost and with less biomass than cellulosic ethanol

Green Car Congress

Furthermore, coproduction systems that utilize a co-feed of biomass and coal (CBTL) and incorporate CO 2 capture and storage (CCS) in the design offer attractive opportunities for decarbonizing both liquid fuels and power generation simultaneously.

New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

Currently, most hydrogen is produced via the steam reforming of natural gas, hydrocarbons and coal. WGS is an endothermic process typically carried out in industry at high temperatures (about 350 °C) with either an iron oxide- or copper-based catalyst to achieve almost complete CO conversion.

This article was first posted on the West Virginia Electric Auto Association (WVEAA) site. Conversely, an EV only uses electricity that must be produced locally, distributed locally, and consumed locally, supporting local jobs.

Fundamental Energy Transitions Can Take a Century

Cars That Think

One hundred and forty years ago, Thomas Edison began generating electricity at two small coal-fired stations, one in London ( Holborn Viaduct ), the other in New York City ( Pearl Street Station ). The early expansion of generation was destined for industry—above all for the conversion from steam engines to electric motors—and for commerce.

A Membrane Strategy for Increasing Hydrocarbon Yield in Biomass-to-Liquids Processes

Green Car Congress

Measured effects on conversion and yield with and without membrane integration (full symbols=without membrane; empty symbols=with membrane). FT synthesis uses syngas (primarily H 2 and CO) generated from coal, natural gas, or biomass. To improve the carbon conversion efficiency of the BTL process, Unruh et al. Click to enlarge.

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.
