  • New Swiss device to monitor carbon dioxide

    A new laser device installed on the Jungfraujoch in Switzerland will help scientists determine the source of carbon dioxide, a major greenhouse gas, on a real-time basis. Until now climatologists tracking carbon dioxide levels in high alpine regions have had to rely on individual samples painstakingly gathered and tested in distance laboratories. The site already hosts a pollution-monitoring ...

  • Rising carbon dioxide and ‘acidified` waters in puget sound

    Scientists have discovered that the water chemistry in the Hood Canal and the Puget Sound, US, main basin is becoming more "acidified," or corrosive, as the ocean absorbs more carbon dioxide from the atmosphere. These changes could have considerable impacts on the region"s shellfish industry over the next several decades. The study, co-sponsored by NOAA, the University of Washington Applied ...


  • EPA Exempts Carbon Dioxide Injection From RCRA Hazardous Waste Regulations

    The Environmental Protection Agency is issuing a final rule that will exempt carbon dioxide streams captured from power plants and industrial sources and injected underground for geologic sequestration from federal hazardous waste regulations. The agency did not make the text of the final rule available Dec. 19. The EPA said carbon dioxide injected into Class VI wells approved for geological ...

  • Carbon Dioxide Levels Identified in Buildings Utilizing Onsite Test Kit

    Last year, an elderly woman in Georgia was found unconscious in a restroom at a McDonald’s restaurant.  The woman later died and it was determined that a lethal dose of carbon dioxide (CO2) had build up when a bleed line for the restaurant’s carbonated beverages, which was located in the wall cavity, became disconnected.   Although extreme cases like these due to carbon ...

  • Burying the climate change problem: greenhouse gas carbon dioxide

    Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be the for the very long term, thousands of years. Now, a team in Brazil, writing in the International Journal of Global Warming has reviewed the risk assessments for this ...

  • Projects Selected for Safe and Permanent Geologic Storage of Carbon Dioxide

    The U.S. Department of Energy (DOE) announced the selection of 13 projects to develop technologies and methodologies for geologic storage of carbon dioxide (CO2). Carbon capture and storage (CCS) research is focused on developing technologies to capture industrially generated CO2, and safely and permanently store it in underground geologic formations, in order to reduce the amount of CO2 being ...

  • Questions and Answers on the proposal for a directive on the geological storage of carbon dioxide

    1) What is carbon capture and storage? Carbon capture and storage is a suite of technological processes which involve capturing carbon dioxide (CO2) from the gases discarded by industry and transporting and injecting it into geological formations. The major application for carbon capture and storage (CCS) is to reduce CO2 emissions from power generation from fossil fuels, principally ...

  • U.S. Carbon Dioxide Emissions Down 11% Since 2007

    Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back slightly as the economy recovered. But shifting ...

  • ASTM D513 - 11e1 Standard Test Methods for Total and Dissolved Carbon Dioxide in Water

    Carbon dioxide is a major respiration product of plants and animals and a decomposition product of organic matter and certain minerals. The atmosphere averages about 0.04 vol % of CO2. Surface waters generally contain less than 10 mg/L, except at local points of abnormal organic or mineral decomposition; however, underground water, particularly deep waters, may contain ...

  • In Milestone, Energy Department Projects Safely and Permanently Store 10 Million Metric Tons of Carbon Dioxide

    In a landmark accomplishment, the U.S. Department of Energy is announcing that a group of carbon capture and storage (CCS) projects supported by the Department have safely captured 10 million metric tons of carbon dioxide (CO2) – the equivalent of removing more than 2 million passenger vehicles from the nation’s roads for one year. This milestone builds on the Obama ...

  • All walled up and no place to go: large-scale geologic sequestration successes put carbon dioxide in its place

    It is the mid-17th century. Jan Baptist Van Helmont, a Belgian chemist, places a carefully measured 62 pounds of coal into a basin, which he ignites, covers, and allows to burn. When the fire has at last smoldered down to nothing but ash and embers, Van Helmont measures the remains and finds not the expected 62 pounds he had started with, but rather one lonely pound of debris.  In his treatise, ...

  • New Report Shows Decline in Carbon Dioxide and Other Pollutants from U.S. Power Plants, but State and Power Company Emissions Vary Widely

    A new report on U.S. power plant emissions from the country’s top 100 electric power producers shows a downward trend in nitrogen oxides (NOx), sulfur dioxides (SO2), mercury and carbon dioxide (CO2) since 2000, with CO2 emissions decreasing 13 percent between 2008 and 2012. The findings show that the industry is already shifting toward a combination of increased energy efficiency and lower ...

  • Predicting the fate of underground carbon

    A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs. One strategy for mitigating greenhouse gases is to inject compressed carbon dioxide into natural aquifers made of permeable rock soaked with brackish salt water. Carbon ...
