Pickle:
I know there's some paranoia in the US about hydrogen - but there's a limit to the amount of helium available (unusually for a gas, it's mined from the ground), using it for balloons instead of essential uses (e.g. medical equipment) is frivolous and wasteful. And helium is harder to contain inside an envelope.
The US military is looking again at hydrogen for unmanned heavy-lift applications - using helicopters as towing tugs for MBT recovery operations, etc. Commercial LTA is again looking at hydrogen - the price and availability compared to helium is advantageous, advances in envelope materials and admix fire retardant gases go some way to addressing the public consciousness tainted by Hindenburg.
You can find several modellers online using hydrogen they're generating themselves rather than buying in helium.

Salute, despite my previous post.

Hydrogen can be extracted from water, making it cheaper and more sustainable. On the other hand, you just know little timmy is going to make his voice all squeaky before he blows out the candles and accidentally charbroil his insides.
With the USA it's all about the lawsuits.
