Hydrogen is a versatile and clean energy carrier that can be used in various applications. Here are some of the most commonly used hydrogen technologies & comparison of their advantages and disadvantages:
1. Steam Methane Reforming (SMR): SMR is the most common method of hydrogen production, accounting for approximately 95% of global production. It involves reacting methane with steam in the presence of a catalyst to produce hydrogen and carbon dioxide.
2. Electrolysis: Electrolysis is a process that uses electricity to split water into hydrogen and oxygen. two types of electrolysis: alkaline and proton exchange membrane (PEM).
3. Electrolysis: Electrolysis is a process that uses electricity to split water into oxygen(O2) and hydrogen(h2). Name of two types of electrolysis: alkaline and proton exchange membrane (PEM).
4. Photobiological: Photobiological hydrogen production involves using photosynthetic microorganisms, such as algae, to produce hydrogen or green microalgae or cyanobacteria.
5. Nuclear: Nuclear hydrogen production involves splitting water using high-temperature nuclear reactors. ...
... This method is a carbon-free way of producing hydrogen, but it is expensive, and there are concerns about the safety and security of nuclear reactors.
6. Solid Oxide Electrolysis Cells (SOEC): SOECs use a ceramic electrolyte to split water into hydrogen and oxygen. This technology is efficient, but it is still in the research and development phase.
7. Thermochemical: Thermochemical hydrogen production involves using chemical and heat reactions to produce hydrogen from fossil fuels or other sources.
