Yes. Hydrogen is collected from water in a proses called electrolysis, (we have a lot of water) in electrolysis an electrical current is sent through the water and the hydrogen (negative ions) is sent towards the negative wire. the hydrogen is sent through a protonic stage membrane fuel cell stack where the hydrogen electrons are split from the atomic nuclei and powers what ever needs doing. The electrons bond back with the rest of the atom and then come back out of the fuel cell, bond with oxygen to change back to H2O.
Yes, it is (96%) produced by coal and oil, but can be made from renewable sources like wind or solar power!
renewable
Hydrogen is a nonrenewable source of energy when used for nuclear fusion (which is still not a technologically attainable power generation mechanism). When used as an energy carrier for oxidation (e.g. fuel cell, and internal combustion engine) hydrogen is not an energy source. In such applications, hydrogen is a man-made resource.
Two typical examples are Oil and Solar power. There will come a time when the oil reserves will run out - making it a non-renewable source of power. Solar power on the other hand will be available as long as the sun continues to provide us with energy. The sun's energy is a continuing thermal 'cycle' turning hydrogen into helium, and back to hydrogen.
No; hydrogen is not a renewable resource.
Hydrogen has significant potential for renewable energy production in the future due to its versatility as a clean fuel source that can be produced using renewable sources like wind and solar power. This makes hydrogen a promising option for reducing greenhouse gas emissions and transitioning to a more sustainable energy system.
There are no natural supplies of hydrogen. It always has to be removed from something, and the commonest source is water (H2O). However, so far, there is no way to remove hydrogen from water that does not use more energy than the resulting hydrogen will produce. If a cheap way is discovered to separate water into Hydrogen and Oxygen then all our worries about global warming and peak oil will be over. A.K.A its renewable EDIT: correction: UV radiation naturally splits H2O molecules in the ocean, producing hydrogen and oxygen, which reacts with O2 in the air, forming ozone (O3). That is how the ozone layer formed. But yes, electrolysis of water to produce hydrogen is not very efficient at the moment. - Oscar
Hydrogen fuel cells themselves are not inherently renewable; their sustainability depends on how the hydrogen is produced. If hydrogen is generated through renewable sources, such as electrolysis powered by solar or wind energy, it can be considered renewable. However, if it is produced from fossil fuels, such as natural gas through steam methane reforming, it is not renewable and can contribute to greenhouse gas emissions. Ultimately, the environmental impact of hydrogen fuel cells hinges on the methods used to produce the hydrogen.
they are renewable
Nuclear fusion is not renewable. It requires hydrogen nuclei as an energy source, and once these have been used in fusion they are not naturally replenished. In fact, fusion power has a very high energy change, rendering it near impossible to reverse the process. A star, for example, is powered by nuclear fusion, and will eventually die out due to a lack of hydrogen.
Hydrogen gas itself is not being destroyed when it is converted to energy. Renewable sources of hydrogen include water electrolysis powered by renewable energy sources like solar or wind power, and biomass gasification. These processes produce hydrogen without depleting finite resources.
The use of fossil fuels is required to create pure hydrogen. APEX!
