A novel demonstration underway at Technische Universität Darmstadt (TU Darmstadt), a research university in Darmstadt, Germany, has shown a calcium carbonate looping (CCL) technology retrofitted at ...

Renewable energy and coke oven gas are two potential sources of hydrogen that can be used for the form of carbon capture called calcium looping. As illustrated in the diagram, using coke oven gas may ...

By Liang-Shih Fan and Elena Chung, Ohio State University Coal plays a big role in America’s energy present and future. According to the U.S. Energy Information Administration (EIA), coal comprises 20 ...

Chemical looping combustion (CLC), an advanced coal power technology that could markedly simplify carbon capture at power plants, has moved significantly closer to commercialization, owing to a ...

Alstom has made significant progress in proving the feasibility of the chemical looping concepts, including completing the first self-sustained operation of a chemical looping combustion unit. Photo ...

How can we burn natural gas without releasing carbon dioxide (CO2) into the air? This feat is achieved using a special combustion method: chemical looping combustion (CLC). In this process, CO2 can be ...

Researchers have discovered a new method by which a catalyst can be used to selectively burn one molecule in a mixture of hydrocarbons -- compounds made of hydrogen and carbon atoms. For the first ...

Thermochemical approaches exploit reversible chemical reactions to capture carbon dioxide and store or release energy at high temperatures. Central to these methods are looping cycles in which a solid ...
