Answer:
It is important for us to be able to make hydrogen from seawater instead of pure water for several reasons:
Abundance: Seawater is abundant and widely available, making it a more sustainable and renewable source of hydrogen compared to pure water, which is often in limited supply.
Cost-effective: Seawater is a low-cost source of hydrogen, as it does not require the use of fresh water, which can be scarce and expensive in many regions.
Energy efficient: Seawater contains dissolved salts and minerals, which can be used as catalysts to speed up the water splitting process and make it more energy efficient.
Environmental impact: Using seawater as a source of hydrogen instead of pure water reduces the amount of freshwater that is used, conserving this precious resource and minimizing the environmental impact of water extraction and transportation.
Versatility: Seawater can be used as feedstock for various hydrogen production methods such as electrolysis, thermolysis, photocatalysis, and biotechnology.
In summary, being able to make hydrogen from seawater is crucial to address the growing energy demand while also preserving fresh water resources, and also to make hydrogen production more sustainable and cost-effective.
