Ammonia as a mobile energy source

Yet another potential option as we transit away from fossil... producing hydrogen from ammonia... good article here.
It all starts well - five times the stored energy density of a Tesla battery and much faster refuel time... but ends up with half the range.

The company - Amogy- private finance at the mo.

Something else for green investors to think about if ammonia ever gets off the ground.

For the moment, fossil... high density, quick refuel... nothing moves faster than a fossil.

I have always been mildly confused why methanol hasn't gained a higher profile as an alternative fuel. On the face of it, it has all the credentials as a fossil fuel replacement. It's essentially made from H2 and CO2. The CO2 can be recycled from the atmosphere by numerous means and the H2 recovered from the water produced in combustion. And it is almost a drop in substitute for present liquid fuels. And methanol, though toxic if you drink it, doesn't stink and make your eyes water like ammonia does.

It has had its champions in the past.
I think it loses to ethanol in energy density, toxicity... and flavour ;)

Pretty low energy density there, too.

Why is meths not a popular fuel for camping stoves when there's a choice? 'Cos it burns far too cool compared to propane/butane, or to paraffin or petrol.
