Is hydrogen fuel cells fossil fuels?
no because hydrogen fuel cells are renewable
Are fuel cells a renewable or non renewable source of energy?
Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)
What has the author Maria A Grech written?
Maria A. Grech has written: 'Hydrogen in the energy mix' -- subject(s): Hydrogen as fuel, Fuel cells, Renewable energy sources
Is hydrogen fuel cells renewable or nonrenewable?
Hydrogen fuel cells deteriorate over time, and must be repaired or replaced. The speed at which they deteriorate is of some concern, as it may take as little as a few years for them to fail.
What are some pros and cons of fuel cells?
Some pros of fuel cells are that it is: -efficient -produces no odor, no noise -reliable -environmentally friendly -is indefinetely renewable, as long as hydrogen is harvested Some cons of fuel cells are: - fuel cells are expensive -you have to harvest hydrogen, which is hard -The volume of the fuel cells are larger than the average internal combustion engine.
What are the potential applications of 0h2 technology in the field of renewable energy?
The potential applications of H2 technology in renewable energy include using hydrogen as a clean fuel for vehicles, storing excess renewable energy, and generating electricity through fuel cells.
Are fuel cells renewable?
Yes
Where are some places hydrogen fuel cells are used?
Hydrogen fuel cells are used in various applications, including transportation, where they power fuel cell vehicles like buses, trucks, and passenger cars. They are also employed in stationary power generation for backup power systems and renewable energy integration. Additionally, hydrogen fuel cells are utilized in industrial settings, such as forklift operations in warehouses, and in aerospace for powering spacecraft.
Does energy used by fuel cells come from the sun?
Yes, the energy used by fuel cells can ultimately be traced back to the sun, especially when the hydrogen used in fuel cells is produced through renewable methods like electrolysis powered by solar energy. In this process, solar energy is converted into electricity, which splits water into hydrogen and oxygen. This hydrogen can then be used in fuel cells to generate electricity. Therefore, while fuel cells themselves do not directly use sunlight, their energy source can be solar-based.
Is hydrogen a fossil fuel?
No, hydrogen is not a fossil fuel because it is not derived from ancient organic matter like oil, coal, and natural gas. Hydrogen is an element that can be sourced from a variety of resources, including water, biomass, and renewable electricity.
Can you use hydrogen peroxyde in a fuel cell?
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
How is hydrogen and fuel cells easily renewed?
Hydrogen can be easily renewed through various methods, primarily by electrolysis, where water is split into hydrogen and oxygen using electricity from renewable sources like wind or solar power. Additionally, hydrogen can be produced from biomass or through the reforming of natural gas, although the latter is less sustainable. Fuel cells, which convert hydrogen into electricity, are efficient and emit only water vapor as a byproduct, making them a clean energy solution. This renewable approach supports the transition to a sustainable energy future.
