Proposed process for low-emissions coal-to-liquids

Green Car Congress

The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. Background.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Process flow diagram. Source: SRI.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Conducive to our new solar process, electrolysis of molten carbonates forms oxides, which precipitate as calcium oxide when mixed with calcium carbonate. Click to enlarge.

Oxford Team Outlines Progress and Potential in CO2 Capture and Conversion to Synthetic Transportation Fuels

Green Car Congress

Natural photosynthesis uses solar energy to recycle CO 2 (and H 2 O) into new plant life (biomass) and ultimately fuels (biofuels). order to take full advantage of the high ‘tank-to-wheel’ efficiency of electric vehicles, critical steps will also be needed to decarbonize the upstream energy (electricity) supply. Jiang et al.

China unveils Dalian National Laboratory for Clean Energy; initial focus on clean fossil-fuel technologies

Green Car Congress

Li says the facility will combine all major areas of energy research, including cleaner fossil fuels, solar power, and fuel cell technologies.Mindful that China relies on coal for more than two-thirds of its electricity, Li expects the DNL to focus much of its resources on clean fossil-fuel technologies, at least initially.

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

Green Car Congress

Schema of synfuel synthesis through solar-driven biomass gasification. Solar energy produces both heat for gasification and H 2 via electrolysis. High temperature heat for biomass gasification is obtained from a molten-salt system in a solar concentrating tower. Energy conversion efficiency (%). From Hertwich et al.
