Carbon–hydrogen bond C−H bond is generally regarded as being non-polar. In structural formulas of molecules, the hydrogen atoms are often omitted. Compound classes consisting solely of C–H bonds and C–C bonds are alkanes, alkenes, alkynes, and aromatic hydrocarbons. Collectively they are known as hydrocarbons. In October 2016, astronomers reported that the very basic chemical ingredients of life—the carbon-hydrogen molecule (CH, or methylidyne radical), the carbon-hydrogen positive ion (CH+) and the carbon ion (C+)—are the result, in large part, of ultraviolet light from stars, rather than in other ways, such as the result of turbulent events related to supernovae and young stars, as
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
