• Carbon dioxide

Why is water management crucial in green hydrogen production?

• To ensure the process does not exacerbate water scarcity

• To increase the cost of production

• Because water is the only byproduct

• Because water is consumed and not returned

How does the water usage of green hydrogen compare to biofuels?

• Both use the same amount of water

• Green hydrogen uses considerably less water

• Biofuels use less water

• Green hydrogen uses more water

What is a potential challenge of using seawater for electrolysis?

• It is not renewable

• It produces harmful emissions

• It requires desalination and handling of corrosive salt

• It is too expensive

What strategy can help mitigate the impact of green hydrogen production on water scarcity?

• Increasing fossil fuel usage

• Using only fresh water

• Ignoring regional water availability

• Importing green hydrogen from water-rich regions

What is a key advantage of green hydrogen over traditional fossil fuels?

• Higher greenhouse gas emissions

• Higher cost

• Lower energy efficiency

• Minimal water usage

What is essential for maximizing the benefits of green hydrogen?

• Careful planning and management

• Increasing fossil fuel consumption
