Exploring EnergApplications of- Hydrogen energy, Ocean y Sources

What is a renewable energy source?

• A renewable energy source is a source of energy that is replenished naturally and can be used repeatedly.

• A source of energy that is only available in limited quantities

• A non-renewable energy source

• A source of energy that is harmful to the environment

How is hydrogen used as a clean fuel?

• Hydrogen is converted into electricity through fuel cells, emitting only water vapor and heat as byproducts.

• Hydrogen is used as a fuel in traditional combustion engines, releasing harmful emissions.

• Hydrogen is primarily used for cooking purposes in households.

• Hydrogen is a renewable energy source that is not suitable for fuel production.

Explain how hydrogen fuel cells work.

• Hydrogen fuel cells convert nitrogen and carbon dioxide into electricity.

• Hydrogen fuel cells use solar energy to produce electricity.

• Hydrogen fuel cells convert hydrogen and oxygen into water, generating electricity and heat.

• Hydrogen fuel cells release greenhouse gases into the atmosphere.

What is wave energy technology?

• Wave energy technology is a method of generating electricity from ocean waves.

• Wave energy technology is a method of generating electricity from wind turbines.

• Wave energy technology involves harnessing geothermal energy from the ocean floor.

• Wave energy technology is a process of converting sunlight into electricity using solar panels.

Describe tidal power generation.

• Tidal power generation is the process of converting energy from the natural rise and fall of tides into electricity.

• Tidal power generation relies on solar panels

• Tidal power generation is based on geothermal energy

• Tidal power generation involves harnessing wind energy

What is ocean thermal energy conversion?

• OTEC is a process that uses the temperature difference between the warm surface waters of the ocean and the cold deep waters to generate power.

• OTEC is a type of marine animal found in deep ocean trenches.

• OTEC is a method of extracting oil from ocean waters.

• OTEC is a term used to describe the process of desalination of seawater.

Why is hydrogen considered a sustainable energy source?

• Hydrogen infrastructure is not widely available

• Hydrogen production is expensive and inefficient

• Hydrogen can be produced from renewable sources, emits no greenhouse gases when used, and can be stored efficiently.

• Hydrogen is highly flammable and poses safety risks

What are the benefits of using hydrogen fuel cells?

• Releases harmful emissions into the environment

• Requires frequent maintenance

• Limited availability of hydrogen fueling stations

• The benefits of using hydrogen fuel cells include being environmentally friendly, producing only water as a byproduct, having high energy efficiency, quick refueling, and long driving ranges.

How does wave energy technology harness energy from the ocean?

• By harnessing geothermal energy from the ocean

• By using devices that capture the motion of waves and convert it into electricity.

• By using wind turbines in the ocean

• By extracting minerals from the ocean floor

What are the environmental advantages of tidal power generation?

• Produces electricity without emitting greenhouse gases, reduces dependence on fossil fuels, and has minimal environmental impact.

• Intensifies reliance on fossil fuels

• Causes significant environmental harm

• Increases greenhouse gas emissions
