Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
Methanation is an important step in the creation of synthetic or substitute natural gas (SNG). [7] Coal or wood undergo gasification which creates a producer gas that must undergo methanation in order to produce a usable gas that just needs to undergo a final purification step.
Formic acid for example can be made by reacting the hydrogen with CO 2. Formic acid combined with CO 2 can form isobutanol. [15] Methanol can be made from a chemical reaction of a carbon-dioxide molecule with three hydrogen molecules to produce methanol and water.
For example, photo-fermentation with Rhodobacter sphaeroides SH2C can be employed to convert some fatty acids into hydrogen. [ 121 ] Fermentative hydrogen production can be done using direct biophotolysis by green algae, indirect biophotolysis by cyanobacteria, photo-fermentation by anaerobic photosynthetic bacteria and dark fermentation by ...
Hydrogenation occurred at a high temperature and pressure, with syngas produced in a separate gasifier. The process ultimately yielded a synthetic crude product, Naphtha , a limited amount of C 3 /C 4 gas, light-medium weight liquids (C 5 -C 10 ) suitable for use as fuels, small amounts of NH 3 and significant amounts of CO 2 .

Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane.It is principally used for producing ammonia or methanol.
The concept of a society that uses hydrogen as the primary means of energy storage was theorized by geneticist J. B. S. Haldane in 1923. Anticipating the exhaustion of Britain's coal reserves for power generation, Haldane proposed a network of wind turbines to produce hydrogen and oxygen for long-term energy storage through electrolysis, to help address renewable power's variable output.

The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization.
