On the tanks are safety valves mounted which also activate above a certain temperature. So the tanks will release the hydrogen. If the hydrogen does not catch fire it will quickly dissipate in the atmosphere. If it does catch fire you will have a colorless flame which burns until the tank is empty. The only reasonable way it can explode is when it vents and the gas accumulates under a ceiling or in a convinced space.
The hydrogen can be produced by elektrolyses , which is zero emission..
A leak in to an enclosed space, such as a car's luggage space, for example? The average car's luggage space would make for a nasty explosion if the worst happened.
Hydrogen can be produced by electrolysis, but the vast majority (c.95% I think) is from steam reforming which is energy intensive and results in CO2.
If we're going to install sufficient renewable capacity to allow generation of sufficient hydrogen for vehicle fuel, we might as well just miss out the middle man and use the electricity directly. Oh, and we're unlikely ever to install sufficient renewable capacity to do that, either via hydrogen or direct use. The UK currently generates about 20% of its electricity demand from renewable sources. Almost all (>99%) of that electricity goes to heating, lighting, industry. Transport is almost entirely oil powered (petrol, diesel).
Of course, we could do it, but there isn't the political will, nor the finance available, to make the UK fully renewable-resource powered - whether that's direct electricity or via hydrogen as storage.
