It can be stored and transported, serving as a clean and versatile energy vector for various applications.
Synthetic Natural Gas Production
Hydrogen generated through electrolysis can also be combined with carbon dioxide (CO2) through a process called methanation. This results in the production of synthetic natural gas (SNG), a renewable alternative to conventional natural gas. This SNG can be injected into existing natural gas infrastructure or used for heating, electricity generation, or even as fuel for vehicles.
Liquid Fuel Synthesis
In the Power-to-Liquid pathway, renewable electricity powers electrochemical or thermochemical processes that facilitate the conversion of hydrogen and carbon dioxide into liquid synthetic fuels. These fuels include synthetic gasoline, diesel, and jet fuel. The production of liquid fuels offers a means to store renewable energy and extend its application to transportation and industries reliant on liquid energy carriers.
Chemical Compound Generation
Power-to-Chemicals technologies encompass diverse reactions that transform renewable electricity into valuable chemical compounds. For instance, the Haber-Bosch process can utilize surplus energy to produce ammonia (NH3), a key component in fertilizers. Methanol (CH3OH) can be synthesized through the combination of carbon dioxide and hydrogen, holding promise for industrial applications, as well as serving as a chemical feedstock.
Integration and Utilization
The synthesized products, whether hydrogen, synthetic gases, liquid fuels, or chemical compounds, can be integrated into existing energy and industrial infrastructure. Hydrogen can be used in fuel cells for electricity generation or as a raw material in industrial processes. Synthetic fuels can power vehicles and machinery, while chemical compounds find applications in various sectors, from agriculture to manufacturing.
