Hydrogen production: How is hydrogen made and what is it?

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.

Producing hydrogen through technological use

Several technologies for hydrogen production exist, which can be used depending on the specific requirements and available resources. Here are some common methods:
 

 

 

 

Sustainability of hydrogen production: Choosing the right energy source

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.

Hydrogen is also often referred to as the "champagne of the energy transition". But how can we produce hydrogen from renewable energies on a large scale?


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:

PEM electrolysis, also known as proton exchange membrane electrolysis, splits water into hydrogen and oxygen using a polymer membrane and electric current.

Advantages:

Disadvantages:

Alkaline electrolysis:

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 (Solid Oxide Electrolysis Cell):

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 electrolysis (Anion Exchange Membrane):

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.

Advantages:

Disadvantages:

There are many contaminants that can threaten your compressed air system, but moisture is among the most prevalent. You may be thinking, but it’s just water, but water can have a devastating impact on your compressed air system, your production equipment, and your end product. The best way to prevent moisture from contaminating your compressed air is with a dryer. …


Compressed air can be one of the most expensive forms of energy for manufacturing plants, often using more energy than other equipment. One horsepower of compressed air requires eight horsepower of electricity. With many air compressors running at efficiencies as low as 10%, there’s often plenty of room for improvement. Fortunately, 50% of compressed air systems at small- to medium-sized industrial facilities have opportunities for low-cost energy conservation. …


As easy as it would make all of our lives, vacuum pumps are far from being “one size fits all”. Not only do you have the size to consider when choosing a vacuum pump, but more importantly type. I will briefly touch on some of the advantages and disadvantages associated with each vacuum technology we deal with. This should give you a better understanding of where to begin your search... …


AIRnet offers moisture-eliminating drop fittings called Quick Drops! Quick Drops make “drop-tees” obsolete, removing the need for extra parts and pipe, while saving time and money. …


Proper compressor installation and commissioning helps ensure trouble-free startup and long-term reliability. Thorough inspection and critical review during each phase of the installation process eliminates “built-in” deficiencies or problems which c... …

And making the switch is easy. All you need is a gas generator and a supply of compressed air. …


Did you know that one of the largest costs for industrial manufacturers is compressed air? That’s right – anywhere from 12% to 40% of a facility’s total energy costs come from its compressed air installation. This means that finding innovative ways (no matter how small) to increase compressed air efficiency can amount to big savings over the long run! Items like leak elimination, air audits, reduced pressure bands, and reducing unloaded running hours are some of the most popular ways to decrease energy usage – but there are many other actions that you can take. Read on to discover additional ways to reduce your costs and make sure your compressor system is running as efficiently as possible! …


A properly sized and designed piping system is a necessary component of any distribution compressed air system. Without this key component in place, the delivery of air from the compressor to the specific points of use will be inefficient and costly, both in the short term as well as in the long term. Let’s look more closely at how to size your compressed air piping system to ensure minimal pressure loss while maintaining maximum efficiency. …


Potential for growth of micro-organisms in a compressed air system is tied to the moisture level (dew point) of the compressed air. In simple terms, if there is moisture in your compressed air, microorganisms such as mold and bacteria have the environment they need to grow and thrive. While it’s true that as air is compressed, much of the moisture present in the intake air will condense, enough moisture remains to allow micro-organisms to proliferate. …


Your compressor installation is a workhorse that requires regular service and maintenance to help it achieve maximum efficiency and longevity. This is where compressor monitoring and data gathering technologies come in, as these provide meaningful information on your system that can be visualized, tracked over extended time periods, and used to make insightful decisions regarding compressor performance.  …

Air compressor leaks can be a substantial source of wasted energy in any system, sometimes wasting 20-30% of a compressor's production. Worst of all, a poorly maintained compressor can have a leak rate expected to equal 20% of total compressed air... …


Choosing the right compressor is essential to your long-term satisfaction and maybe, to the profitability of your business. Many times compressors are based on a single factor alone, such as horsepower or tank size, which is only part of the story. …


In oil injected screw compressors, there is a thin layer of oil found between the rotors to create a seal and maintain proper efficiency as the compression occurs. The unfortunate side effect of this solution is that oil may carry over to the point of use in your air system. This can be mitigated by having correct filtration in place to remove the oil contaminants in your air. Additionally, many individuals may decide to opt for a completely oil-free solution, with the use of a scroll compressor or water injected screw compressor. …


Most businesses concentrate on the air compressor and consider the piping as a secondary concern. The piping system can make or break your business. Faulty, inefficient piping can cause pressure loss and lost power. Keeping a close eye on the overall layout, installations and maintenance of your air piping system will help keep your business running at its’ optimal efficiency. …
