The Scientific Basis of Seawater Fuel Production

The concept of producing fuel from seawater relies on extracting hydrogen, the most abundant element in the universe, from water molecules (H₂O). While seawater contains a vast reservoir of hydrogen, extracting it is a complex and energy-intensive process. Several methods are being explored, each with its own advantages and challenges:

1. Electrolysis: Splitting Water with Electricity

Electrolysis is the most well-established method for splitting water into hydrogen and oxygen. An electric current is passed through the water, causing the water molecules to break apart. The hydrogen gas is then collected and can be used as fuel.

Challenges:

• Energy Intensive: Electrolysis requires a significant amount of electricity, making it crucial to use renewable energy sources to power the process.
• Electrode Corrosion: The electrodes used in electrolysis can corrode in seawater due to the presence of salt and other minerals, requiring the development of durable and corrosion-resistant materials.
