Zero? A cup of water doesn't typically contain tritium.
You can fuse anything lighter than iron and it will release energy. The process with tritium is just easier. Stars can extract the nuclear potential energy from hydrogen and oxygen just fine.

I'd love to see someone fusing water at sea level.
That's a lot of activation energy, but it takes money to make money. Err, takes energy to make energy.
Please don't let this become news until there's a production ready design. There are lots of these battery innovations promising multiple x of improvement, yet never delivering anything. Maybe it's actually interesting to battery chemistry enthusiasts, but you can't give them headlines like this either. Bring the down votes.
The problem is even though we have gotten miraculously stable lithium batteries, they still aren't 'bulletproof' enough that explosion and fire risks are negligible. Add 3x more energy to it and it starts becoming a really big problem. This is what has kept 99.9% of these miraculous battery technologies we always hear about, too dangerous to use in consumer devices. If it is as stable, or preferably more stable, than…
If even half of these amazing battery technologies had come true, my car would be driven by a D cell battery. But I'm ok that it hasn't, because I once heard a battery chemistry guy say that "the higher capacity a battery is the more it resembles a bomb." I can't find the reference any more, but with all the Samsungs and Teslas catching fire, it rings true.
> the higher capacity a battery is the more it resembles a bomb A battery is a package containing the reagents necessary for a highly energetic reaction. A bomb is a package containing the reagents necessary for a highly energetic reaction. A high-capacity battery is effectively a bomb, pretty much by definition.

Actually a bomb is something that is programmed to detonate intentionally under certain conditions. There are plenty of other similarly energetic chemicals around the house, like gas in cylinders. The problem with some batteries is, unlike a bomb, the detonation conditions are hard to control. Luckily battery ignition, as enegetic as it is, is low velocity.

Petrol is fairly flammable and explosive too, but we still drive around with big tanks of it under the back seat

Gasoline is not explosive, it requires oxygen to burn. We wouldn't allow normal passenger vehicles to drive around with big tanks of explosives.

Gasoline only explodes under very specific environmental conditions, otherwise it just burns.
One could say the same about lithium :).
When was the last time you read about battery explosion?

When was the last time you read about a Car carrying tank of fuel sudden burst into frame? When was the last time you read about battery explosion?
