As demand rises for clean energy technologies, firms are now leaning towards low-carbon emission energy solutions. Hydrogen is emerging as the prime energy carrier, specifically where it is sourced sustainably. Therefore, electrolysis has emerged as an integral component for developing the Green Hydrogen Market owing to its ability to produce hydrogen from renewable sources.
The process of electrolysis generates green hydrogen by employing an electrical current to separate hydrogen from oxygen (the two components present in water). If electrolysis occurs using renewable energy sources, such as solar or wind, the process is known as green hydrogen production.
How Electrolysis Produces Green Hydrogen
Electrolysis is the process by which hydrogen and oxygen are separated from water molecules using electricity. In case the source of energy used in the electrolysis process is renewable, then it can be stated that green hydrogen will be obtained due to no carbon emissions being produced during the procedure.
Connection With Renewable Energy Technologies
A connection exists between electrolysis technologies and the generation of renewable energy, as it enables overcoming the issue of energy instability. By utilizing electrolysis technology, it is possible to store surplus energy.
As an example, wind farms may provide surplus energy to electrolyzers during off-peak hours to create hydrogen that will later be available for use.
Progress in Electrolyzer Technologies
Technological development of electrolyzers is contributing to improving efficiency and scaling up the process of hydrogen production. Several electrolyzer technologies exist – among them, there are alkali, proton exchange membrane, and solid oxide electrolyzers.
For example, PEM electrolyzers have been gaining much attention lately due to their high flexibility and operability in terms of energy availability, making them applicable to integrating with renewables. Such developments help decrease the cost of production and increase efficiency.
Green Hydrogen and Industry Transition
The development of electrolysis allows the use of green hydrogen as an alternative source of energy for industries. Electrolysis-produced green hydrogen can be applied to several industrial processes to minimize carbon footprint.
