Hydrogen is becoming increasingly important as a promising clean energy carrier – especially with a view to a more climate-friendly future. But have you ever wondered what hydrogen actually is and how it is produced? In this article, we look at the basics and technologies used to produce hydrogen and what makes hydrogen a special element.
Several technologies for hydrogen production exist, which can be used depending on the specific requirements and available
resources. Here are some common methods:
It should be noted that not all hydrogen production processes are equally sustainable or environmentally friendly. The sustainability of
hydrogen production depends on the energy source used and the CO2 emissions during the production process. In order to make the most of the
benefits of hydrogen as a clean energy source, it is of great importance to use renewable energy sources for the production of hydrogen.
The use of renewable energies such as solar energy, wind energy or hydropower can significantly reduce CO2 emissions in hydrogen production,
making it more sustainable and sustainable. Environmentally friendly hydrogen is produced. This is an important step towards achieving a
low-carbon future and tackling climate change.
Electrolysis is the process that is most promising. The electrolysis process enables the environmentally friendly production of hydrogen, especially if the electricity used for it comes from renewable energy sources. These technologies play an important role in enabling clean hydrogen to emerge as a sustainable energy carrier for various applications. We took a detailed look at the different technologies and took a look at the advantages and disadvantages of each.
PEM electrolysis, also known as proton exchange membrane electrolysis, splits water into hydrogen and oxygen using a polymer membrane and electric current.
Advantages:
Disadvantages:
In alkaline electrolysis, water is split into its constituents hydrogen and oxygen using an alkaline electrolyte, typically an aqueous solution of potassium hydroxide.
Advantages:
Disadvantages:
SOEC stands for Solid Oxide Electrolysis Cell and refers to a high-temperature electrolytic cell that converts water into hydrogen and oxygen at high temperatures and with solid oxides as the electrolyte.
Advantages:
Disadvantages:
AEM stands for Anion Exchange Membrane and refers to an electrolyzer technology that uses a special membrane that allows permeability to negatively charged ions and splits water into hydrogen and oxygen using electric current.
