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.

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.

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.

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

Green Car Congress

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). Molten carbonate electrosynthesized boron-doped CNTs exhibit high electrical conductivity. —Ren et al. Licht (2017).

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

In both electric- and hydrogen-favoring cases, availability of low-carbon electricity and hydrogen prolonged the use of petroleum-fueled ICE vehicles. For example, the study found that the availability of carbon capture and storage (CCS) technology has a major impact on the lowest cost passenger vehicle fuel and technology choice.
