There are many companies here selling the product and they explain the process of making aluminum containers to hold in the hydrogen... They also explain that it has a 4 month shelf life due to very slow leaks. They also explain that it should be consumed immediately after opening for the same reason...

Many many companies sell hydrogen water, I posted 2... I could keep posting them, but you have access to Google.
