TED: How green hydrogen could end the fossil fuel era | Vaitea Cowan

The video discusses the potential of green hydrogen as a clean energy source to replace fossil fuels. It explains the process of water electrolysis to produce green hydrogen and its applications in various sectors like steel production and aviation. The video highlights the challenges of cost and production speed, and presents Enapter's approach to mass-produce electrolyzers, making green hydrogen more accessible and affordable. The goal is to transition to a sustainable energy future by leveraging green hydrogen and renewable electricity.

What is the key process involved in producing green hydrogen?

• Nuclear fission

• Photosynthesis

• Combustion of fossil fuels

• Water electrolysis

Why is green hydrogen considered crucial for the future of energy?

• It is the only renewable energy source

• It is easier to produce than electricity

• It can replace the 80% of energy consumption that is in the form of molecules

• It is cheaper than fossil fuels

How does green hydrogen help in reducing CO2 emissions in steel production?

• By using more electricity

• By using coal more efficiently

• By replacing coal with a clean molecule that emits only water

• By increasing the temperature of the reaction

What is a significant challenge in using batteries for aviation?

• Batteries are too light

• Batteries are not powerful enough

• Batteries are too expensive

• Batteries are too heavy

Which of the following is NOT an application of green hydrogen?

• Fuel for global shipping

• Energy storage across seasons

• Direct combustion as a fuel

• Nuclear power generation

What is the main challenge in making green hydrogen a widespread energy source?

• Lack of interest from industries

• Speed, scale, and cost of production

• High cost of green electricity

• Insufficient research and development

What historical analogy is used to describe the potential mass production of electrolyzers?

• The invention of the light bulb

• The rise of personal computers

• The development of the steam engine
