Specifically, if I wanted to purchase a large amounts of helium, what are my options for purchasing helium in a state that is suitable for long term storage?
It's my understanding that if I were to buy helium in bulk it would be shipped cold, as a liquid. Keeping helium in liquid form for 10-20+ years would involve a lot of serious refrigeration.
Are there other reasonable options for bulk, long term storage?
This may not seem like much of a "chemistry" question but since this is used in chemical sciences, I assume this is a need that some may be aware and may have a good answer since this is an elemental material that some may use on a very common basis.
