The water gas shift reaction is the reaction between carbon monoxide and steam to form hydrogen and carbon dioxide: CO + H 2 O ⇌ CO 2 + H 2. This reaction was discovered by Felice Fontana and nowadays is adopted in a wide range of industrial applications, such as in the production process of ammonia, hydrocarbons, methanol, hydrogen and other chemicals.
Hydrogen production from natural gas and heavier hydrocarbons is achieved by partial oxidation. A fuel-air or fuel-oxygen mixture is partially combusted, resulting in a hydrogen- and carbon monoxide-rich syngas. More hydrogen and carbon dioxide are then obtained from carbon monoxide (and water) via the water-gas shift reaction. [35]
[8]: 21–24 In electricity generation and hydrogen production, CCS is envisioned to complement a broader shift to renewable energy. [8]: 21–24 CCS is a component of bioenergy with carbon capture and storage, which can under some conditions remove carbon from the atmosphere.
(The Center Square) – A proposed $7.5 billion ammonia production facility in Ascension Parish could position Louisiana as a global leader in clean energy. "It would be the largest [ammonia ...
Scientists have developed a new carbon capture system that absorbs CO2 and produces useable electricity and hydrogen fuel.
It is currently the least expensive method for hydrogen production available in terms of its capital cost. [16] In an effort to decarbonise hydrogen production, carbon capture and storage (CCS) methods are being implemented within the industry, which have the potential to remove up to 90% of CO 2 produced from the process.

Less than 1% of dedicated hydrogen production is low carbon: steam fossil fuel reforming with carbon capture and storage, green hydrogen produced using electrolysis, and hydrogen produced from biomass. [4] CO 2 emissions from 2021 production, at 915 MtCO 2, [35] amounted to 2.5% of energy-related CO 2 emissions [36] and 1.8% of global ...
Researchers have also suggested using biomass as a carbon source for fuel production. Adding hydrogen to the biomass would reduce its carbon to produce fuel. This method has the advantage of using plant matter to cheaply capture carbon dioxide. The plants also add some chemical energy to the fuel from biological molecules.
