Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a method that can reduce the levels of mercury in sulfuric acid by more than 90%, even from low levels. It is therefore a worldwide challenge that sulfuric acid often contains one of the most toxic substances: mercury.

U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

A recent United Nations provision has banned the use of mercury in spacecraft propellant. Although no private company has actually used mercury propellant in a launched spacecraft, the possibility was alarming enough—and the dangers extreme enough—that the ban was enacted just a few years after one U.S.-based

Texas Clean Energy Project signs long-term CO2 offtake agreement with Whiting Petroleum for enhanced oil recovery; 90% CO2 capture from IGCC coal polygen plant

Green Car Congress

The TCEP would integrate coal gasification, combined-cycle power generation, CO 2 capture, and. Whiting will be the first in the Permian to purchase CO 2 from a power project that will be produced through the coal-gasification process. The TCEP integrates coal gasification, combined-cycle power generation, CO 2 capture, and.

Duke study finds China’s synthetic natural gas plants will have heavy environmental toll; 2x vehicle GHG if used for fuel

Green Car Congress

Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change. —Robert B.

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.

GE Technology Selected for Hydrogen Energy IGCC Project in California

Green Car Congress

HEI is a joint venture of BP Alternative Energy and multinational mining company Rio Tinto Hydrogen. IGCC plants gasify solid fuels into syngas, which then is used by a gas turbine combined-cycle system to generate electricity, providing a cleaner, economical coal-to-power option. Earlier post.).

Stanford launches major new natural gas research initiative

Green Car Congress

Compared with burning coal, natural gas emits about half the carbon dioxide and substantially less soot, mercury and sulfur. —Mark Zoback, a professor of geophysics and NGI’s director. US emissions of CO 2 have declined to the level of the mid-1990s.
