It is a liquid that after irradiating stores that energy while still cold and can be made to release it in form of heat on demand. but also it's low grade heat mostly useful for heating and not for electricity generation. It would be simpler to just build long range transmission lines or put energy intensive manufacturing near PV farm in sunny region

it's transparent too so you can just put pv panel underneath to capture the rest
you get 1.6MJ/kg just by irradiating this thing, nothing else is needed and its storable for months as noncorrosive room temperature liquid
to make ammonia you need to have pv to turn light to electricity then make hydrogen out of it then make ammonia in haber process, each step generates losses and none are practical on small scale
there is a problem that it can heat itself up so hard during decomposition that it can just go on without catalyst
aaand it boils water again
of course, on a city-sized boat
only after years of kicking and screaming, and companies that made CFCs switched to more expensive HFCs and later HFOs so it's not like they went out of the business. (alternative is use of hydrocarbons which is much cheaper but flammability was used as a reason to restrict their use) CFCs are also still used as chemical intermediates and as late as during covid there was an operational illegal R12 factory somewhere in northern china
they stood no chance, never knew what hit them




all of that without heat pumps too
