OSU team demonstrates Coal-Direct Chemical Looping for more efficient and low carbon coal heat release

Green Car Congress

An Ohio State University team has demonstrated the successful operation of Coal-Direct Chemical Looping (CDCL)—which chemically harnesses coal’s energy and efficiently contains the carbon dioxide produced before it can be released into the atmosphere. Hot iron and coal ash are left behind. 2 millimeters across.

Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

Comparison of coal consumption and CO 2 emissions for co-production and separate production of liquids and power. Conventional CTL plant gasifies coal to produce a syngas which is then converted in a Fischer-Tropsch reactor to products. Even with CCS, the liquid product costs are comparable to recent crude oil prices.

DOE awards $7M to eight oxy-combustion coal technology projects; carbon capture, utilization and storage

Green Car Congress

The US Department of Energy (DOE) selected eight projects to advance the development of transformational oxy-combustion technologies capable of high-efficiency, low-cost carbon dioxide capture from coal-fired power plants. Additional analyses include the evaluation of pressurizing the limestone chemical looping combustion process.

DOE, RTI to Design and Build Coal Syngas Cleanup System for IGCC Power Plants to Reduce Cost of Removing Contaminants, Capturing CO2; Potential for Synthetic Chemicals and Fuels

Green Car Congress

The system also holds the potential to reduce the cost of producing chemicals, transportation fuels, and substitute natural gas from gasified coal. DOE and RTI will design, build, and test a warm gas cleanup system—based on RTI’s high-temperature syngas cleanup technology—to remove multiple contaminants from coal-derived syngas.

Steelmaker ArcelorMittal Europe targets 30% cut in carbon emissions by 30% by 2030

Green Car Congress

Initiatives and technologies underway or to be implemented at ArcelorMittal Europe – Flat Products’ different sites include: Carbalyst – capture waste gases from the blast furnace and biologically convert it into bio-ethanol. LCA studies predict a CO 2 reduction of up to 87% from Carbalyst bio-ethanol compared with fossil transport fuels.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency. Cost considerations on the total infrastructure or cost of ownership were also outside the scope of this work but are nevertheless important, they team noted.

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).
