Please tell me in the US who offers these! I had been asking companies here in the US if that was possible, in the works, or already available and I got a resounding NO because of the instability of h/c.   I eventually got an international company that had it but it was still in their governments "approval" stage that takes quite some time.  If we have that here, I would love to know where it is so I can get updated on how it was done and the trials results.

Thank you,
