While we may hear of this being a possible fuel source, people forget that there is a production involved. This production method consists of breaking water molecules into hydrogen and oxygen gases by using electricity. It is imperative to research this method and the importance of the electricity.
Electrolysis Defined
According to the Department of Energy, electrolysis is a process that occurs within a device called an electrolyzer. The electrolyzer uses electricity to break water molecules into hydrogen and oxygen, and they can be as simple as small devices to as large as full-scale production facilities.
Variations of an electrolyzer consist of different electrolytes and conditions.
It can be seen that there are a variety of the devices used within the production method.
The Value of the Electricity Used
The U.S. Department of Energy states that the source of the electricity used in electrolysis has an impact on the sustainability of the produced fuel. According to the article, renewable and nuclear energy sources are two examples of electricity sources currently being considered for large-scale production of hydrogen.
Suppose two of these electrolysis centers are using the same production methods, but with different sources of electricity. The centers can have the same production equipment, but the amount of emissions released will be different.
The similarity of the production equipment and the difference in the electricity sources show that the name hydrogen fuel cannot describe the entire production process.
The Electricity Source And Its Availability
The Department of Energy also discusses that the availability of the electricity can determine the amount of hydrogen fuel produced.
In this instance, the electrolysis would utilize extra renewable electricity.
However, a compelling project will include a distribution plan for the produced fuel. Developers must consider where the fuel will be used and how to meet those needs. A promising
opportunity to use available electricity is an important consideration, but not the only consideration in developing a reliable supply.
Conclusion
Electrolysis can be seen as a link between electricity production and hydrogen fuel production. The value of this process depends on the electricity source, the equipment used within the production, and the needs of the fuel. Considering the entire production is important when determining the value of hydrogen fuel versus other fuel sources.
