Summits for a Sustainable Planet

Hydrogen Generator

Summits AEM and PEM electrolysers modules are the right choice If you are looking for a reliable and efficient way to produce green hydrogen from renewable energy sources. In both our AEM and PEM electrolysers the hydrogen is produced by passing an electric current through water. The current splits the water molecules into hydrogen and oxygen atoms. The hydrogen atoms are then collected on one side of the membrane, while the oxygen atoms are collected on the other side. Electrolysers are highly efficient, reliable, and durable. They are also modular and scalable, making them easy to deploy and expand as needed.

PEM Electrolysers

PEM stands for proton exchange membrane, a technology that uses a solid polymer membrane to split water into hydrogen and oxygen. Our PEM electrolysers are compact, modular, and scalable, ranging from 1 to 10,000 Nm3/h of hydrogen production capacity. They can operate at high pressures and respond quickly to changes in power input, making them ideal for grid balancing and energy storage applications. PEM electrolysers are highly efficient and reliable, and they are becoming increasingly popular for hydrogen production applications. With our PEM electrolysers, you can benefit from lower operating costs, longer lifetime, and higher safety standards than conventional electrolysis methods. Contact us today to find out more about our PEM electrolyser models and how they can help you achieve your green hydrogen goals.

PEM electrolysers offer several advantages over other types of water electrolysers, including:

High Efficiency

PEM electrolysers have a higher efficiency than other types of water electrolysers, meaning that they can produce more hydrogen with less electricity.

Fast Response Time

PEM electrolysers can quickly respond to changes in electricity demand, making them ideal for use with renewable energy sources such as solar and wind.

Wide Operating Range

PEM electrolysers can operate at a wide range of temperatures and pressures, making them suitable for a variety of applications.

Compact Size

PEM electrolysers are relatively compact in size, making them easy to install and transport.

AEM Electrolysers

AEM electrolysers are a new type of technology that is revolutionizing the way we produce hydrogen. Unlike traditional alkaline electrolysers, AEM electrolysers use a specialized membrane to separate the hydrogen and oxygen produced during electrolysis.

How our AEM Electrolysers Work

The specialized membrane used in AEM electrolysers is made of a material that is permeable to hydroxide ions (OH-). This means that the OH- ions can pass through the membrane, while the hydrogen and oxygen atoms cannot. This ensures that the hydrogen and oxygen are kept separate, which prevents them from recombining into water. AEM electrolysers are a rapidly developing technology with the potential to revolutionize the way we produce hydrogen. As the technology continues to mature, we can expect to see AEM electrolysers become even more efficient, affordable, and versatile.
