Hydrogen as a Future Fuel Source Quiz

True or false: Hydrogen is a primary energy source.

True or false: Obtaining hydrogen requires an input of energy.

True or false: Hydrogen can be used as an energy carrier, unlike petroleum.

True or false: Burning hydrogen or using it in a fuel cell produces harmful emissions.

True or false: Early applications of hydrogen are likely to be in heavy industry.

True or false: Making hydrogen required vast amounts of renewable energy sources until recently.

True or false: Hydrogen is less safe than gasoline for use in vehicles.

True or false: Hydrogen is more energy-dense than batteries, but cost and infrastructure are still obstacles.

Hydrogen is an abundant element that could be a fuel of the future to aid the transition to net zero emissions.
Hydrogen needs to be obtained by splitting molecules, which requires an input of energy.
Hydrogen can be used as an energy carrier, unlike petroleum which is a primary energy source.
Burning hydrogen or using it in a fuel cell only produces water as waste, making it a green fuel.
Early applications of hydrogen are likely to be in heavy industry and can help decarbonize the global economy.
Until renewables existed at scale, making hydrogen required vast amounts of fossil fuel or nuclear energy, making it less efficient and more expensive.
Public perception of hydrogen safety is overblown; it can be safer than internal combustion vehicles that use gasoline.
Hydrogen is more energy-dense than batteries, but there are issues of cost and fueling infrastructure that need to be addressed.
Sustainable hydrogen requires reducing it using sustainable energy, but it still requires energy-intensive processes.
Technological advances are making hydrogen production more efficient and cheaper, driving a new hydrogen economy with a projected investment of $500 billion.

Test your knowledge about hydrogen as a potential fuel of the future, its production, applications, safety, efficiency, and role in decarbonizing the global economy.
