Hydrogen compounds are only required to contain carbon. However, most of them also contain hydrogen, and because it is the carbon-hydrogen bond which gives this class of compounds most of its particular chemical characteristics, carbon-hydrogen bonds are required in some definitions of the word "organic" in chemistry. Millions of hydrocarbons are known, and they are usually formed by complicated synthetic pathways that seldom involve elementary hydrogen. Compounds of hydrogen are often called hydrides, a term that is used fairly loosely. The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H, and is used when
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
