Magnetic bottle is said to store hydrogen (and then convert into helium?)

TL;DR

Magnetic bottle is said to store hydrogen and then convert into helium.
How exactly does it store hydrogen and how can hydrogen be converted to helium? Is it the complete valency of hydrogen that gives helium?

They say that no other devices can store hydrogen, so how exactly is the magnetic bottle able to do so? More importantly how does it convert it into helium?

The application you are referring to is fusion. Magnetic fields are used to confine a plasma which has a temperature of around 100 million degrees Kelvin.

Hydrogen at normal temperatures (and pressures) can be stored in physical bottles.

Oh, so hydrogen fuses with another hydrogen to become stable and get the configuration of helium or is there another mechanism?

There are a number of nuclear reactions that involve different intermediaries (see Han Bethe Nobel Prize) but they are similar.

A magnetic bottle can be used to store charged particles, called ions, usually in the form of a plasma. But it is actually a very poor method of storing anything, even plasma, as leakage through the ends is fairly significant. It's just one of the easiest methods of storing plasma for research, as better storage methods are vastly more complicated and expensive.

Hydrogen is fused with itself to make helium, but we are usually talking about fusing dueterium and tritium, which are isotopes of hydrogen. That is, regular, plain, basic hydrogen is just a single proton with a single electron. Dueterium is a proton bonded to a neutron and tritium is a proton bonded to two neutrons. All three have a single electron and a single proton, making them chemically identical except for differences in mass. Plain hydrogen and dueterium are both entirely stable. Tritium is unstable and will undergo beta decay with a half-life of about 12 years.

Helium can be formed from the fusion of deuterium with itself or with tritium. Specifically helium-4, the most common isotope of helium. Another isotope of helium, helium-3, is created when tritium naturally decays. Both helium-3 and helium-4 are chemically identical, differing only by mass.

Just about any compressed gas cylinder can store hydrogen in gaseous form, though there will always be some leakage due to hydrogen's very small size. However these cylinders cannot store plasma. You need magnetic bottles or another magnetic-based storage device to handle plasma.

Thanks a lot for clearing this up!
