Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

Green Car Congress

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. Also, liquefying high-oxygen content low-ranking coal and biomass also consumes more hydrogen and produces more CO 2 , significantly reducing process efficiency.

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.

NETL researchers devise process to create energy and fuel from slag

Green Car Congress

In gasification, slag is made from mineral impurities that remain after a carbon feedstock such as coal has been gasified. The other slag contains high levels of vanadium (III) oxide generated during gasification using petroleum coke-based carbon feedstocks. 2014.01.104.

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.
