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.

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). Our hope is that this present summary helps to catalyse such a worthwhile development. Tags: Carbon Capture and Conversion (CCC) Climate Change Emissions Fuels. Jiang et al. Click to enlarge.

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. used three.

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.

National Research Council Report on Americas Energy Future Highlights Vehicle Efficiency Technologies, Conversion of Biomass and Coal-to-Liquids Fuels, and Electrifying the Light Duty Fleet with PHEVs, BEVs and FCVs

Green Car Congress

The report ( America’s Energy Future: Technology and Transformation ) of the Committee on America’s Energy Future addresses a potential new portfolio of energy-supply and end-use technologies—their states of development, costs, implementation barriers, and impacts—both at present and projected over the next two to three decades.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

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.
