Carbon dioxide in Earth's atmosphere initial carbon dioxide in the atmosphere of the young Earth was produced by volcanic activity, modern volcanic activity releases only 130 to 230 megatonnes of carbon dioxide each year. These natural sources are nearly balanced by natural sinks, physical and biological processes which remove carbon dioxide from the atmosphere. For example, some is directly removed from the atmosphere by land plants for photosynthesis and it is soluble in water forming carbonic acid. There is a large natural flux of into and out of the biosphere and oceans. In the pre-industrial era these fluxes were largely in balance. Currently about 57%
Carbon Recycling International as methanol fuel cells. Production of renewable methanol does not depend on agricultural resources, as hydrogen and carbon dioxide are the primary inputs. CRI's emissions-to-liquids production process is based on three main modules, carbon dioxide purification, hydrogen generation and the methanol synthesis and purification system. The catalytic conversion process from hydrogen and carbon dioxide occurs in one step, while production of methanol from fossil fuels, such as natural gas or coal, involves several reforming steps to obtain syngas followed by the catalytic step. The George Olah Plant, or the GO Plant, has a name-plate capacity of 5 million liters per
