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.

US Awards $1B in Recovery Act Funding to FutureGen 2.0; Advanced Coal Repowering and CO2 Storage

Green Car Congress

The plant’s new boiler, air separation unit, CO 2 purification and compression unit will deliver 90% CO 2 capture and eliminate most SO x , NO x , mercury, and particulate emissions. The pipeline network, along with the repository in Mattoon, helps to lay the foundation for a regional CO 2 network.

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

TCEP will be an integrated gasification combined cycle (IGCC) 400 MW power/poly-gen plant that will capture 90% of the carbon dioxide, 99% of the sulfur, more than 95% of the mercury, and eliminate more than 90% of the nitrogen oxides produced by the process. Ultimately, some 99% of the injected CO 2 can be permanently stored (i.e.

But he did live to see these astrophysical parallels lead to important practical consequences: They helped my group at ASML produce a bright, reliable EUV light source, leading to a major advance in commercial chipmaking. Plenty of pundits suggested that the technology could never be commercialized.

The Birth of Random-Access Memory

Cars That Think

Over the years, memory has been made up of vacuum tubes, glass tubes filled with mercury and, most recently, semiconductors. The first electronic digital computer capable of storing instructions and data in a read/write memory was the Manchester Small Scale Experimental Machine, known as the Manchester “Baby.”

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

Green Car Congress

That figure does not include damages from climate change, harm to ecosystems, effects of some air pollutants such as mercury, and risks to national security, which the report examines but does not monetize. Life-cycle CO 2 emissions from nuclear, wind, biomass, and solar power appear to be negligible when compared with fossil fuels.
