Rocket Fuel

[Egil Skallagrimsson]

HG has rules for chemical power sources for space craft instead of the fusion plants and gravitic drives, but what is the "standard" price of chemical fuel for M drives and P-plants?

I probably can't see it for looking, so any ideas? I assume it is more than the 500Cr/dt for purified hydrogen, but how much more expensive? 1000Cr/dt, 5000Cr/dt?

Any thoughts/page references?

Thanks

and what is the fuel? hydrazine? ethanol? naphtha? kerosene? biofuel?

I don't know. If L-hyd then you need to carry O2 as well. :|

You could decide that the power plants are high tech fuel
cells, like those of 2300AD, which use hydrogen and oxy-
gen at the same cost as hydrogen fuel, since the produc-
tion of hydrogen from water creates oxygen as its bypro-
duct. Many current rockets also use liquid hydrogen and
liquid oxygen as their propellants, so the cost for their fuel
could also be the same, or almost the same, as that of hy-
drogen fuel.

Not specified in HG, so any of the above, and perhaps something more exotic

Good thinking, that might be the way around it. The chemical p-plants and m-drives in HG are much less efficient in use, so would still work out considerably more expensive to run, even if the fuel costs are about the same.
