Hydrogen Energy

Hydrogen energy refers to the use of hydrogen as a clean and versatile source of energy for various applications. Like electricity, Hydrogen is a secondary source of energy. It stores and carries energy produced from other resources (fossil fuels, water, and biomass).

Unlike primary energy sources such as coal, oil, or sunlight, Hydrogen is not a primary energy source in itself.Instead, it acts as an energy vector or carrier. This means that Hydrogen serves as a medium for storing and transporting energy, rather than being a direct source of energy itself. This distinction is essential to understand the role of hydrogen in the energy landscape.
Hydrogen production relies on other primary energy sources, such as natural gas, electricity, or biomass. These primary sources power the chemical processes that result in the creation of hydrogen. Hydrogen can be produced using renewable energy sources through a process called electrolysis, where water is split into hydrogen and oxygen. This Hydrogen can then be used as a clean energy carrier or fuel for various applications.

Blue Hydrogen

Blue hydrogen is primarily derived from natural gas through steam reforming, which involves the combination of natural gas and heated water in the form of steam. The result is the production of hydrogen, along with carbon dioxide as a byproduct. However, the defining characteristic of blue hydrogen is the implementation of carbon capture and storage (CCS) technology to capture and store carbon dioxide.

Blue hydrogen is often referred to as “low-carbon hydrogen” because the steam reforming process still generates greenhouse gases, but the implementation of CCS reduces the carbon footprint of the production process.
Compared to gray hydrogen, blue hydrogen has the potential to significantly reduce carbon emissions, as the captured carbon can be utilized or stored, preventing it from entering the atmosphere. However, the use of natural gas as the primary source of blue hydrogen production still relies on non-renewable fossil fuels.
