Hydrogen Technologies

• Hydrogen is a clean, flexible energy source with
  a variety of applications. The most prevalent and
  lightest chemical element in the universe is
  hydrogen. The building block of the universe,
  hydrogen, is also required for a wide range of
  chemical reactions and processes.

• With so many applications, hydrogen is a flexible
  and clean energy source. These are some of the
  most popular hydrogen technologies, and their
  advantages and disadvantages are contrasted
• Steam Methane Reforming (SMR) SMR is the most
  common technique used to make hydrogen,
  accounting for about 95 of the hydrogen produced
  globally. Methane and steam react to produce
  hydrogen and carbon dioxide when a catalyst is
  present. SMR is a proven technology that is
  affordable, efficient, and contributes to climate
  change by producing carbon dioxide as a
  byproduct.
• Electrolysis The electrolysis process, which
  uses electricity, separates water into hydrogen
  and oxygen. There are two types of electrolysis
  PEM (proton exchange membrane) and alkaline.
  Alkaline electrolysis is a tried-and-true method
  that is still economically priced, although being
  less effective than PEM electrolysis. Being more
  expensive than alkaline electrolysis, PEM
  electrolysis is a relatively new technique.

1. Biomass Gasification A gas that can be converted
   into hydrogen is produced by the process of
   biomass gasification, which involves heating
   organic materials like wood or agricultural waste
   in the absence of oxygen. A significant amount of
   biomass fuel is required for biomass
   gasification, which is an expensive and
   carbon-neutral method of creating hydrogen yet
   renewable.
2. Nuclear High-temperature nuclear reactors are
   used in the nuclear hydrogen generating process
   to split water. This technology creates hydrogen
   without releasing carbon emissions, while being
   expensive and raising concerns about the security
   and safety of nuclear reactors.
3. Photobiological Photobiological hydrogen
   generation is the process by which photosynthetic
   microorganisms including algae produce hydrogen.
   This method, which is still in the research and
   development phase, has the potential to produce
   hydrogen in a renewable and carbon-neutral
   manner.
4. Solid Oxide Electrolysis Cells (SOEC) Hydrogen
   and oxygen are separated from water in SOECs by
   means of a ceramic electrolyte. This technology
   works well, even if research and development on
   it is still in its early phases.

• Thermochemical Heat and chemical reactions can
  be used to make hydrogen thermochemically from
  fossil fuels or other sources. This strategy may
  be carbon neutral, but research and development
  are still in progress.
• Explanation of Hydrogen Technologies
• Hydrogen technologies encompass all methods and
  technologies involved in producing, distributing,
  storing, and using hydrogen as an energy source.
  Utilizing hydrogen, the most abundant element in
  the universe, in a variety of forms can meet
  energy needs while minimizing environmental
  impact.
