True
Study Notes
- 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.
