  2. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [4] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue ...

  3. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock.

  4. Hybrid sulfur cycle - Wikipedia

    en.wikipedia.org/wiki/Hybrid_sulfur_cycle

    Simplified diagram of the Hybrid sulfur cycle. The hybrid sulfur cycle (HyS) is a two-step water-splitting process intended to be used for hydrogen production.Based on sulfur oxidation and reduction, it is classified as a hybrid thermochemical cycle because it uses an electrochemical (instead of a thermochemical) reaction for one of the two steps.

  5. Hydrogen economy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_economy

    In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [40] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue ...

  6. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  7. Hydrogen technologies - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_technologies

    Hydrogen technologies are applicable for many uses. Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen economy . Hydrogen is a chemical widely used in various applications including ammonia production, oil refining and energy. [ 1 ]

  8. Briggs–Rauscher reaction - Wikipedia

    en.wikipedia.org/wiki/Briggs–Rauscher_reaction

    The colour changes seen during the reaction correspond to the actions of the two processes: the slowly increasing amber colour is due to the production of free iodine by process B. When process B stops, the resulting increase in iodide ion enables the sudden blue starch colour. But since process A is still acting, this slowly fades back to clear.

  9. Hydrogen fuel cell power plant - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_fuel_cell_power_plant

    A hydrogen fuel cell power plant is a type of fuel cell power plant (or station) which uses a hydrogen fuel cell to generate electricity for the power grid. They are larger in scale than backup generators such as the Bloom Energy Server and can be up to 60% efficient in converting hydrogen to electricity.
