What is an advantage of using hydrogen as a fuel?
Hydrogen fuel cells provide an inherently clean source of energy, with no adverse environmental impact during operation as the byproducts are simply heat and water. Unlike biofuel or hydropower, hydrogen doesn’t require large areas of land to produce.
What are 3 advantages of hydrogen fuel cells?
Hydrogen fuel cells (HFCs) produce no harmful emissions, eliminating the costs associated with handling and storing toxic materials like battery acid or diesel fuel. In fact, when fueled with pure hydrogen, the only by-products are heat and water, making our products a zero-emission, sustainable power source.
What are the 2 main problems with using hydrogen for fuel?
The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
What are 3 characteristics of hydrogen?
Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth.
What are the properties of hydrogen and oxygen?
Hydrogen — reaction with oxygen Oxyhydrogen is most explosive at a hydrogen:oxygen ratio of 2:1, also known as Brown’s Gas, or 2:5 for hydrogen and air. Hydrogen gas is highly flammable and will burn in air at an extremely wide range of concentrations (between 4% and 75% by volume).
What are the advantages and disadvantages using hydrogen as fuel?
Hydrogen is incredibly dense in energy and is able to provide a lot of power. It is 3 times more powerful than most fossil based fuel sources so less hydrogen is required to perform the same tasks. This is why hydrogen is used in space exploration to fuel spaceships, aeroplanes, boats, cars and fuel cells.
What are the advantages and disadvantages of using hydrogen gas as fuel?
Hydrogen Fuel Cell Advantages and Disadvantages in Material…
- Hydrogen Fuel Cell Technology.
- Advantage: High Energy Density Improves Productivity.
- Disadvantage: The Use of Fossil Fuels in Hydrogen Production.
- Disadvantage: Hydrogen Storage and Transportation.
- Disadvantage: Fuel Cell Efficiency.
What are the pros and cons of hydrogen energy?
Hydrogen fuel cells Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.
What are the advantages and disadvantages of hydrogen energy?
It is Dependent on Fossil fuels Hydrogen energy is renewable and has a minimal environmental impact, but its separation from oxygen requires other non-renewable sources such as coal, oil and natural gas. Fossil fuels are still needed to produce hydrogen fuel.
