Why do you think the emergency propulsion component is destroyed after use? This has always confused me. The only reason I can think of is for gaming purposes. I mean it's not like the thing would blow up after use.
I can think of two work arounds until the code is changed, if ever.
One would be to make the emergency propulsion component use a lot (1000-2000) of supply when used, this makes sense if you are using more fuel to get the extra movement. The only problem with that is by using quantum reactors / emergency supply pods you reduce the penalty for using them every turn.
The other option is to make the component larger, say 50-75 kt space each. This would probably force you to limit how many you put on a vessel.
I hope they fix this little anomality along with the emergency resupply pod. Then you would only use them when needed.
