TED: The carbonless fuel that could change how we ship goods | Maria Gallucci

The video discusses the potential of green ammonia as a clean alternative to fossil fuels in the shipping industry. It highlights the environmental impact of current shipping practices and explores how green ammonia, which can be produced using renewable energy, could revolutionize the industry. The video also covers the necessary infrastructure, potential adoption parallels with electric vehicles, and complementary technologies like wind-assisted propulsion. The historical context of shipping and the urgent need for change to combat climate change are emphasized.

What is the main environmental benefit of using green ammonia in shipping?

• It is easier to store than other fuels.

• It does not produce carbon dioxide.

• It increases the speed of ships.

• It is cheaper than diesel.

What is a key factor in making green ammonia?

• Relying on nuclear power.

• Utilizing renewable electricity.

• Combining carbon and hydrogen.

• Using fossil fuels for production.

What role do renewable energy sources play in the production of green ammonia?

• They provide the electricity for electrolysis.

• They are stored in ammonia tanks.

• They are used to power ships directly.

• They are converted into ammonia directly.

Why are chemical tankers considered early adopters of ammonia engines?

• They already carry ammonia in their cargo holds.

• They have more advanced technology.

• They travel shorter distances.

• They are smaller and easier to modify.

What is a potential challenge in adopting green ammonia for shipping?

• Lack of interest from shipbuilders.

• High cost of ammonia production.

• Limited availability of nitrogen.

• Need for new infrastructure near ports.

What is a similarity between the adoption of green ammonia and electric vehicles?

• Both need supportive policies and infrastructure.

• Both rely on fossil fuels.

• Both are more expensive than traditional options.

• Both require new types of engines.

How does wind-assisted propulsion benefit cargo ships?

• It speeds up the loading process.

• It reduces the need for diesel engines.

• It lowers the ship's height.

• It increases the cargo capacity.
