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).

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.

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.

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.

List of The Best 10 Alternative Fuels for Cars that Could Replace Gasoline

Get Electric Vehicle

It is a liquid alcohol fuel produced from a variety of feedstocks, including natural gas, coal, biomass, or even carbon dioxide. Bioethanol is being produced converting carbon-based agricultural feedstock such as sugar cane, bagasse, grain, barley, potatoes. It is less expensive to produce for IC engine vehicles.

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. which fraction of the reactants is converted to the desired products (e.g., Click to enlarge.

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

Green Car Congress

The concept’s key feature is the use of high-temperature heat from a solar concentrating tower to drive the chemical process of converting biomass to a biofuel, obtaining a near-complete utilization of carbon atoms in the biomass. Energy conversion efficiency (%). The purpose of the concept, said Edgar G.
