Scientists Develop Technology That Burns Natural Gas With No CO2 Emissions (scienceblog.com)

New submitter Ben Sullivan writes: Researchers and engineers in Vienna have developed a way to burn natural gas without releasing CO2 into the air through a combustion method called chemical looping combustion (CLC). In this process, CO2 can be isolated during combustion without having to use any additional energy, which means it can then go on to be stored. The method had already been applied successfully in a test environment, and has now been upscaled to allow use in up to a 10 MW facility. ScienceBlog.com reports: "A granulate made of metal oxide circulates between the two chambers and is responsible for transporting oxygen from air to fuel: 'We pump air through one chamber, where the particles take up oxygen. They then move on to the second chamber, which has natural gas flowing through it. Here is where the oxygen is released, and then where flameless combustion takes place, producing CO2 and water vapor,' explains Stefan Penthor from the Institute of Chemical Engineering at TU Wien. The separation into two chambers means there are two separate flue gas streams to deal with too: air with a reduced concentration of oxygen is discharged from one chamber, water vapor and CO2 from the other. The water vapor can be separated quite easily, leaving almost pure CO2, which can be stored or used in other technical applications."

    From the article:

    "“The large-scale underground storage of CO2 in former natural gas reservoirs could be very significant in the future,” believes Stefan Penthor. The United Nations Intergovernmental Panel on Climate Change (IPCC) also sees underground CO2 storage as an essential component of any future climate policy. However, CO2 can only be stored if it has been separated as pure as possible – just as it is with the new CLC combustion method."

    It's pretty well understood. Increasing CO2 in the atmosphere means more energy is trapped in the lower atmosphere and on the surface. In general terms, that means heat, though it also means more energetic storm systems and other atmospheric phenomena as well.

    It's been known for over a century what happens if you increase CO2 concentrations in the atmosphere. For anyone to act like somehow it's all still a mystery is to basically ignore the actual, real, verified physical properties of carbon dioxide and other greenhouse gasses.

    If you are pumping it into an underground reservoir that used to hold natural gas, then you already know the reservoir can hold gas for geological time periods. (Or at least it could until someone drilled into it.)

    I don't know why these global warming idiots just don't do their own research before opening their mouths.

    Did you ever think that maybe we did?
