Photoelectrolysis of water

The semiconductor crucial to this process, absorbs sunlight, initiating electron excitation and subsequent water molecule splitting into hydrogen and oxygen.

[6] Advantages: Utilizing sunlight, photoelectrolysis serves as a renewable method for hydrogen production, offering scalability and adaptability across different geographical conditions.

Challenges: The primary hurdles include the still-developing efficiency of the process and the intermittent nature of solar energy, which can affect consistent hydrogen production.

Although currently more expensive than traditional methods like steam methane reforming, the potential for technological advancements could make it more economically viable.

Continued research and investment in overcoming existing challenges will be crucial to harness the full potential of this technology.
