Green hydrogen production: from the creation of the molecule to its use

From the production of hydrogen by extraction to the use of the molecule… Lhyfe, producer of green hydrogen, explains everything about the life cycle of renewable hydrogen as it is manufactured by Lhyfe.

What are the stages of renewable hydrogen production?

Here are the three stages of Lhyfe renewable hydrogen production. Lhyfe’s production units produce without any CO2 emissions (as opposed to carbonated hydrogen):

Electrolysis of water

Hydrogen is produced from water from rivers, the ocean, rain, or leachate. Electrolysis is a process that splits the chemical bonds of H2O molecules. It is done using renewable energy. During this process, oxygen is released into the air. On the other hand, there is no carbon dioxide (CO2) emission.

Hydrogen (H2) compression

This process reduces the volume of hydrogen and increases the pressure.

Hydrogen purification

In this step, the remaining traces of oxygen (O2) and water (H2O) are removed.

How is renewable hydrogen transported? For what purposes?

Hydrogen can be stored in containers outside the plant. It is then transported by truck. The hydrogen produced can then be used for :

  • Transportation: The hydrogen that has been produced can power hydrogen vehicles. These vehicles, therefore, release zero CO2 emissions when driven.
  • Industry: delivered hydrogen can also be used to power factories (in small quantities)

When used for industry, in massive quantities, hydrogen can be transported directly through a pipe connection. This allows the factory to be supplied for the following uses:

  • lass
  • steel
  • food manufacturing
  • plastics

Lhyfe’s hydrogen production is made from renewable energy. That's why we call it green. This is an effective way to decarbonize your business!

What is a hydrogen fuel cell? A comprehensive guide

Hydrogen fuel cells are a clean and efficient source of energy that have been gaining attention in recent years due to their potential to revolutionize various industries, such as transportation and power generation. In this article, we'll explore the basics of hydrogen fuel cells, how they work, their advantages, limitations, and various applications.

What is a Hydrogen Fuel Cell?

A hydrogen fuel cell is an electrochemical device that converts the chemical energy stored in hydrogen and oxygen into electricity, heat, and water. Unlike traditional combustion engines that burn fossil fuels, hydrogen fuel cells generate electricity without harmful emissions, making them an environmentally friendly alternative to conventional energy sources.

How Does a Hydrogen Fuel Cell Work?

The basic principle behind hydrogen fuel cells is the electrochemical reaction between hydrogen and oxygen. There are several types of hydrogen fuel cells, but two of the most common are Proton Exchange Membrane (PEM) fuel cells and Solid Oxide Fuel Cells (SOFC).

Proton Exchange Membrane (PEM) Fuel Cells

PEM fuel cells consist of an anode, a cathode, and a proton exchange membrane sandwiched between them. Hydrogen gas is fed to the anode, where it encounters a catalyst, usually made of platinum. The catalyst causes the hydrogen molecules to split into protons and electrons. The protons pass through the proton exchange membrane to the cathode, while the electrons travel through an external circuit, generating electricity. At the cathode, the protons, electrons, and oxygen from the air combine to form water and heat, the only byproducts of the process.

Solid Oxide Fuel Cells (SOFC)

SOFCs operate at higher temperatures than PEM fuel cells, typically around 800-1,000°C. They use a solid ceramic electrolyte to transport oxygen ions from the cathode to the anode. At the anode, hydrogen reacts with the oxygen ions, producing water and releasing electrons. These electrons flow through an external circuit, generating electricity.

Advantages of Hydrogen Fuel Cells

  1. Environmentally friendly: Hydrogen fuel cells produce zero greenhouse gas emissions, as their only byproducts are water and heat.
  2. High efficiency: Hydrogen fuel cells are more energy-efficient than traditional combustion engines, as they can convert up to 60% of the energy stored in hydrogen into electricity.
  3. Quiet operation: Unlike combustion engines, hydrogen fuel cells operate quietly, making them suitable for various applications, such as residential power generation.
  4. Fuel flexibility: Some fuel cells can utilize different types of fuels, including natural gas and biogas, in addition to hydrogen.

Challenges and Limitations

  1. High cost: The manufacturing cost of hydrogen fuel cells, especially those using platinum catalysts, can be high.
  2. Hydrogen storage and infrastructure: Storing and transporting hydrogen can be challenging due to its low energy density and the lack of a comprehensive hydrogen infrastructure.
  3. Durability and lifespan: Some fuel cell types may have a limited lifespan due to degradation of components, such as the electrolyte and catalysts.

Applications of Hydrogen Fuel Cells


Hydrogen fuel cells have been widely explored as a clean alternative to conventional internal combustion engines in vehicles.
