The only thing I'd be concerned about is having highly combustible elements in the home. Maybe have them in a garage or require them to be away from the house, and also require very thick tanks.
And I can't imagine it'd be too difficult to do the same thing at filling stations, they have the same getup as is in a home, only larger, for those who might be away from home when they need to fuel up.
Yes *struts*, about 15% of all our electricity comes from renewable hydroelectric. The only downside is that damming can do damage to the immediate environment. 13% of our power comes from nuclear. 1.5% of our power comes from wind, too. Solar only accounts for about .2%. We still have quite a ways to go, but 30% of our energy coming from non-fossil fuels is a good start.
