Solar cells, lithium-ion batteries, and fuel cells, who might develop better in the future?

I will not describe some macro-level things in a long form here. It's just as simple as dividing lithium-ion batteries and fuel cells and solar cells into equal parts and quality, putting aside the pros and cons of various products we have seen so far, such as the large size of fuel cells and so on. Returning to answering this question from a market perspective, after all, the last question is whether it is possible for a product to stand out and occupy most of the applications. It has already been said. Lithium-ion batteries are energy storage, fuel cells are energy conversion, and solar cells are also energy conversion, but energy storage needs to be realized through storable carriers. We stretched the time dimension a little longer. For example, 50 years, 100 years, or 200 years. Lithium-ion batteries will develop and progress. In the future, as raw materials become less and less, they will be gradually replaced by new materials, but this energy storage method will not change. Remember that all portable equipment needs batteries. If fuel cells are used in the future Even if the technology advances to the size of a fingernail or smaller, I would like to ask, who wants to inject fuel into the Bluetooth headsets, mobile phones, or laptops they wear? Solar cells, is solar energy really clean? Of course, the direct use of solar energy is definitely clean, but if storage is to be achieved, other batteries are still needed to support the use. In addition, solar power generation is a kind of large investment and requires a large area to be realized. The limitation is very large. This may also be the reason why solar energy has not been popularized until now. Most solar energy applications are now commercialized It can support its high maintenance cost. I believe that in the future, this pattern will not change much. This is a very awkward application. In the future, it will be limited to commercialized applications. For example, large office buildings, public places and other places that require a lot of electricity during the day. Fuel cell, why should we put this to the end? Let's put aside our feelings and put it briefly on the technical level. Fuel cell is a very good application. This technology may be the mainstream way of electric vehicles in the future. If there are objections, imagine your family's fuel car. If the long-distance endurance of the car is to be realized, the electric car with the battery solution of charging and replacement is far inferior to the fuel cell. Of course, the current technology is certainly not possible, but it may be possible in the future. However, if this is Japanese technology, I can also say. This will not work. Summary: Lithium-ion batteries, solar cells, and fuel cells are products for several different applications. Products specialized in different fields have their own meanings, just like pots and pans in the kitchen at home. It is not possible that one's prominence can replace another's function. That is absolutely impossible. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
