Hydrogen peroxide in concentrated form can be made onsite with solar energy can can power our every need.

"Recently H2O2/propylene has been proposed for an inexpensive single-stage-to-orbit (SSTO) vehicle. Its fuel tank would contain propylene with a H2O2-filled bladder floating in it. This combination offers 15% superior Isp to O2/RP4 (a kerosene used as rocket propellant), does not need turbines or cryogenic storage or hardware, and greatly reduces the cost of the booster. The potential of this and other alternative systems is discussed in some detail at Dunn Engineering"

Highly misleading. Hydrogen peroxide is not the fuel even in that rocket, the propylene is the fuel.

not exactly they be used as fuel for jet but they can be used as propellant...

Is the Hydrogen Peroxide propellant factor cost effective to move a jet?

H2O2 is not a rocket fuel by itself. H2O2 is an oxidizer. H2O is very stable, but H2O2 has an extra oxygen which it readily donates to a fuel, such as kerosene or alcohol.

Peroxide isn't used as a jet fuel. The difference between a jet and a rocket is that a rocket needs to carry its own oxidizer with it, while an airplane operates in the atmosphere, taking its oxygen from outside.

Peroxide is commonly used in small rockets. For big rockets, they use liquid oxygen, but it's extremely difficult stuff to handle. H2O2 doesn't have to be kept cold.

What oxider could you add that would burn Hydrogen peroxide?

H2O2 is an oxidizer, and a powerful one at that, more so than pure O2. It's got an oxidation potential near 2V. To oxidize it further, you'd need something like fluorine (oxidiation potential 3V), which will oxidize just about anything.

So generally, you don't oxidize your H2O2; it's taking the reaction the wrong way. You do the opposite: reduce it. In the process, it oxidizes something else (like kerosene or flaked aluminum) releasing vast amounts of heat energy.

Hydrogen peroxide can not burn, it is already burned, if you want to look at it that way. It helps the fuel burn (oxidize). It is the oxidizer. As phryne said, you can use it to burn kerosene, alcohol, or any other fuel you want to burn. It is not a fuel.

I reworded the question differently in another question to better understand how Hydrogen Peroxide dynamics propel small jets. I'm looking to understand, how liquid hydrogen peroxide can be used as a propellant.

Rockets are not the same thing as jets. H2O2 can not be used as jet fuel at all. It is not suitable for any sort of aircraft. It can not propel rockets by itself except for very small ones. When used as a propellant for things like torpedoes it is very dangerous.

H2O2 has been used as jet fuel in experimental craft, but not in anything practical. H2O2 is unstable; it decomposes into water and O2, releasing a lot of heat. All it needs is a good catalyst. It's done as a high school chemistry experiment, e.g.

http://scientist.wetpaint.com/page/Decomposition+of+Hydrogen+Peroxide+Lab

But it's impractical for jet fuel, especially since you're ignoring all that nice O2. That's energy being left on the table.
